启用隐藏管理功能显示所有站点设置Tested on:

这段代码做了一些很酷的事情。它将向设置菜单添加一个附加选项，并链接到；“所有设置”；这将显示数据库中与WordPress站点相关的所有设置的完整列表。下面的代码将仅使此链接对管理员用户可见，并对所有其他用户隐藏它。

// CUSTOM ADMIN MENU LINK FOR ALL SETTINGS
   function all_settings_link() {
    add_options_page(__(\'All Settings\'), __(\'All Settings\'), \'administrator\', \'options.php\');
   }
   add_action(\'admin_menu\', \'all_settings_link\');

修改登录徽标（&M）；图像URL链接Tested on:

此代码允许您轻松修改WordPress登录页面徽标以及此徽标的href链接和标题文本。

add_filter( \'login_headerurl\', \'namespace_login_headerurl\' );
/**
 * Replaces the login header logo URL
 *
 * @param $url
 */
function namespace_login_headerurl( $url ) {
    $url = home_url( \'/\' );
    return $url;
}

add_filter( \'login_headertitle\', \'namespace_login_headertitle\' );
/**
 * Replaces the login header logo title
 *
 * @param $title
 */
function namespace_login_headertitle( $title ) {
    $title = get_bloginfo( \'name\' );
    return $title;
}

add_action( \'login_head\', \'namespace_login_style\' );
/**
 * Replaces the login header logo
 */
function namespace_login_style() {
    echo \'<style>.login h1 a { background-image: url( \' . get_template_directory_uri() . \'/images/logo.png ) !important; }</style>\';
}

EDIT: 如果要使用站点徽标替换登录徽标，可以使用以下内容动态提取该信息（在上测试WP3.5):

function namespace_login_style() {
    if( function_exists(\'get_custom_header\') ){
        $width = get_custom_header()->width;
        $height = get_custom_header()->height;
    } else {
        $width = HEADER_IMAGE_WIDTH;
        $height = HEADER_IMAGE_HEIGHT;
    }
    echo \'<style>\'.PHP_EOL;
    echo \'.login h1 a {\'.PHP_EOL; 
    echo \'  background-image: url( \'; header_image(); echo \' ) !important; \'.PHP_EOL;
    echo \'  width: \'.$width.\'px !important;\'.PHP_EOL;
    echo \'  height: \'.$height.\'px !important;\'.PHP_EOL;
    echo \'  background-size: \'.$width.\'px \'.$height.\'px !important;\'.PHP_EOL;
    echo \'}\'.PHP_EOL;
    echo \'</style>\'.PHP_EOL;
}

在搜索结果中包括自定义帖子类型

// MAKE CUSTOM POST TYPES SEARCHABLE
function searchAll( $query ) {
 if ( $query->is_search ) { $query->set( \'post_type\', array( \'site\', \'plugin\', \'theme\', \'person\' )); } 
 return $query;
}
add_filter( \'the_search_query\', \'searchAll\' );

Add your custom post types to your sites main RSS feed by default.

// ADD CUSTOM POST TYPES TO THE DEFAULT RSS FEED
function custom_feed_request( $vars ) {
 if (isset($vars[\'feed\']) && !isset($vars[\'post_type\']))
  $vars[\'post_type\'] = array( \'post\', \'site\', \'plugin\', \'theme\', \'person\' );
 return $vars;
}
add_filter( \'request\', \'custom_feed_request\' );

Include custom post types in "Right Now" admin dashboard widget

// ADD CUSTOM POST TYPES TO THE \'RIGHT NOW\' DASHBOARD WIDGET
function wph_right_now_content_table_end() {
 $args = array(
  \'public\' => true ,
  \'_builtin\' => false
 );
 $output = \'object\';
 $operator = \'and\';
 $post_types = get_post_types( $args , $output , $operator );
 foreach( $post_types as $post_type ) {
  $num_posts = wp_count_posts( $post_type->name );
  $num = number_format_i18n( $num_posts->publish );
  $text = _n( $post_type->labels->singular_name, $post_type->labels->name , intval( $num_posts->publish ) );
  if ( current_user_can( \'edit_posts\' ) ) {
   $num = "<a href=\'edit.php?post_type=$post_type->name\'>$num</a>";
   $text = "<a href=\'edit.php?post_type=$post_type->name\'>$text</a>";
  }
  echo \'<tr><td class="first num b b-\' . $post_type->name . \'">\' . $num . \'</td>\';
  echo \'<td class="text t \' . $post_type->name . \'">\' . $text . \'</td></tr>\';
 }
 $taxonomies = get_taxonomies( $args , $output , $operator ); 
 foreach( $taxonomies as $taxonomy ) {
  $num_terms  = wp_count_terms( $taxonomy->name );
  $num = number_format_i18n( $num_terms );
  $text = _n( $taxonomy->labels->singular_name, $taxonomy->labels->name , intval( $num_terms ));
  if ( current_user_can( \'manage_categories\' ) ) {
   $num = "<a href=\'edit-tags.php?taxonomy=$taxonomy->name\'>$num</a>";
   $text = "<a href=\'edit-tags.php?taxonomy=$taxonomy->name\'>$text</a>";
  }
  echo \'<tr><td class="first b b-\' . $taxonomy->name . \'">\' . $num . \'</td>\';
  echo \'<td class="t \' . $taxonomy->name . \'">\' . $text . \'</td></tr>\';
 }
}
add_action( \'right_now_content_table_end\' , \'wph_right_now_content_table_end\' );

删除除管理员用户以外的所有用户的更新通知Tested on:

此代码将确保除“之外，没有其他用户”；“管理”；更新可用时由WordPress通知。。

// REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
   global $user_login;
   get_currentuserinfo();
   if ($user_login !== "admin") { // Change admin to the username that gets the updates
    add_action( \'init\', create_function( \'$a\', "remove_action( \'init\', \'wp_version_check\' );" ), 2 );
    add_filter( \'pre_option_update_core\', create_function( \'$a\', "return null;" ) );
   }

已更改版本，仅显示管理员用户的更新通知（而不仅仅是用户“admin”）：

// REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;
       get_currentuserinfo();
       if (!current_user_can(\'update_plugins\')) { // Checks to see if current user can update plugins
        add_action( \'init\', create_function( \'$a\', "remove_action( \'init\', \'wp_version_check\' );" ), 2 );
        add_filter( \'pre_option_update_core\', create_function( \'$a\', "return null;" ) );
       }

从Google CDN加载jQuery

// Even more smart jQuery inclusion :)
add_action( \'init\', \'jquery_register\' );

// Register from Google and for footer
function jquery_register() {

    if ( !is_admin() ) {

        wp_deregister_script( \'jquery\' );
        wp_register_script( \'jquery\', ( \'https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js\' ), false, null, true );
        wp_enqueue_script( \'jquery\' );
    }
}

// Remove version info from head and feeds
function complete_version_removal() {
    return \'\';
}
add_filter(\'the_generator\', \'complete_version_removal\');

这使得通过添加垃圾邮件和删除链接更容易管理前端的评论**

// Spam & delete links for all versions of WordPress
function delete_comment_link($id) {
    if (current_user_can(\'edit_post\')) {
        echo \'| <a href="\'.get_bloginfo(\'wpurl\').\'/wp-admin/comment.php?action=cdc&c=\'.$id.\'">del</a> \';
        echo \'| <a href="\'.get_bloginfo(\'wpurl\').\'/wp-admin/comment.php?action=cdc&dt=spam&c=\'.$id.\'">spam</a>\';
    }
}

最后，我喜欢将发布到RSS提要的时间推迟10-15分钟，因为我总是在文本中发现至少几个错误。其他用途是，在将内容推送给RSS阅读器之前，您希望内容在一天或一周内对您的站点是独占的。

// Delay feed update
function publish_later_on_feed($where) {
    global $wpdb;

    if (is_feed()) {
        // Timestamp in WordPress format
        $now = gmdate(\'Y-m-d H:i:s\');

        // Value for wait; + device
        $wait = \'10\'; // integer

        // http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_timestampdiff
        $device = \'MINUTE\'; // MINUTE, HOUR, DAY, WEEK, MONTH, YEAR

        // Add SQL syntax to default $where
        $where .= " AND TIMESTAMPDIFF($device, $wpdb->posts.post_date_gmt, \'$now\') > $wait ";
    }
    return $where;
}
add_filter(\'posts_where\', \'publish_later_on_feed\');

设置post修订的最大数量，以避免DB膨胀

/**
 * Set the post revisions unless the constant was set in wp-config.php
 */
if (!defined(\'WP_POST_REVISIONS\')) define(\'WP_POST_REVISIONS\', 5);

自定义管理菜单的顺序Tested on: WordPress 3.0.1

此代码允许您重新组织“管理”菜单中元素的顺序。您只需单击“管理”菜单中的现有链接，然后将所有内容复制到/wp admin/URL之前。下面的顺序表示“新管理”菜单的顺序。

// CUSTOMIZE ADMIN MENU ORDER
function custom_menu_order($menu_ord) {
    if (!$menu_ord)
        return true;
    return array(
     \'index.php\', // This represents the dashboard link
     \'edit.php?post_type=events\', // This is a custom post type menu
     \'edit.php?post_type=news\',
     \'edit.php?post_type=articles\',
     \'edit.php?post_type=faqs\',
     \'edit.php?post_type=mentors\',
     \'edit.php?post_type=testimonials\',
     \'edit.php?post_type=services\',
     \'edit.php?post_type=page\', // This is the default page menu
     \'edit.php\', // This is the default POST admin menu
 );
}
add_filter(\'custom_menu_order\', \'custom_menu_order\');
add_filter(\'menu_order\', \'custom_menu_order\');

用于更改EXPERT长度的函数Tested on:

默认情况下，所有摘录的字数上限为55个字。使用以下代码，您可以覆盖此默认设置：

function new_excerpt_length($length) { 
    return 100;
}

add_filter(\'excerpt_length\', \'new_excerpt_length\');

本例将摘录长度更改为100个单词，但您可以使用相同的方法将其更改为任何值。

在“管理文章/页面”列表中添加缩略图您可以将其添加到功能中，以便在“管理/编辑文章和页面”列表中显示带有缩略图预览的新列。

/****** Add Thumbnails in Manage Posts/Pages List ******/
if ( !function_exists(\'AddThumbColumn\') && function_exists(\'add_theme_support\') ) {
 
    // for post and page
    add_theme_support(\'post-thumbnails\', array( \'post\', \'page\' ) );
 
    function AddThumbColumn($cols) {
 
        $cols[\'thumbnail\'] = __(\'Thumbnail\');
 
        return $cols;
    }
 
    function AddThumbValue($column_name, $post_id) {
 
            $width = (int) 35;
            $height = (int) 35;
 
            if ( \'thumbnail\' == $column_name ) {
                // thumbnail of WP 2.9
                $thumbnail_id = get_post_meta( $post_id, \'_thumbnail_id\', true );
                // image from gallery
                $attachments = get_children( array(\'post_parent\' => $post_id, \'post_type\' => \'attachment\', \'post_mime_type\' => \'image\') );
                if ($thumbnail_id)
                    $thumb = wp_get_attachment_image( $thumbnail_id, array($width, $height), true );
                elseif ($attachments) {
                    foreach ( $attachments as $attachment_id => $attachment ) {
                        $thumb = wp_get_attachment_image( $attachment_id, array($width, $height), true );
                    }
                }
                    if ( isset($thumb) && $thumb ) {
                        echo $thumb;
                    } else {
                        echo __(\'None\');
                    }
            }
    }
 
    // for posts
    add_filter( \'manage_posts_columns\', \'AddThumbColumn\' );
    add_action( \'manage_posts_custom_column\', \'AddThumbValue\', 10, 2 );
 
    // for pages
    add_filter( \'manage_pages_columns\', \'AddThumbColumn\' );
    add_action( \'manage_pages_custom_column\', \'AddThumbValue\', 10, 2 );
}

删除对自己博客的pingTested on:

// Remove pings to self
function no_self_ping( &$links ) {
    $home = get_option( \'home\' );
    foreach ( $links as $l => $link )
        if ( 0 === strpos( $link, $home ) )
            unset($links[$l]);
}
add_action( \'pre_ping\', \'no_self_ping\' );

启用GZIP输出压缩通常应将服务器设置为自动执行此操作，但许多共享主机不执行此操作（可能是为了提高客户端带宽使用率）。

 if(extension_loaded("zlib") && (ini_get("output_handler") != "ob_gzhandler"))
   add_action(\'wp\', create_function(\'\', \'@ob_end_clean();@ini_set("zlib.output_compression", 1);\'));

显示数据库查询、花费的时间和内存消耗Tested on:

function performance( $visible = false ) {

    $stat = sprintf( \'%d queries in %.3f seconds, using %.2fMB memory\',
            get_num_queries(),
            timer_stop( 0, 3 ),
            memory_get_peak_usage() / 1024 / 1024
        );

    echo $visible ? $stat : "<!-- {$stat} -->" ;
}

然后，上面的代码下面的代码将自动将上面的代码插入到您的公共网站的页脚中（确保您的主题正在调用wp_footer):

add_action( \'wp_footer\', \'performance\', 20 );

可以多次调用。

自动从帖子内容中提取第一幅图像Tested on:

此代码将自动提取与帖子关联的第一个图像，并允许您通过调用getImage函数来显示/使用它。

// AUTOMATICALLY EXTRACT THE FIRST IMAGE FROM THE POST
function getImage($num) {
    global $more;
    $more = 1;
    $link = get_permalink();
    $content = get_the_content();
    $count = substr_count($content, \'<img\');
    $start = 0;

    for($i=1;$i<=$count;$i++) {
        $imgBeg = strpos($content, \'<img\', $start);
        $post = substr($content, $imgBeg);
        $imgEnd = strpos($post, \'>\');
        $postOutput = substr($post, 0, $imgEnd+1);
        $postOutput = preg_replace(\'/width="([0-9]*)" height="([0-9]*)"/\', \'\',$postOutput);;
        $image[$i] = $postOutput;
        $start=$imgEnd+1;
    }

    if(stristr($image[$num],\'<img\')) {
        echo \'<a href="\'.$link.\'">\'.$image[$num]."</a>";
    }
    $more = 0;
}

启用实时站点上使用的错误调试和日志记录这是我编写的一段代码，它利用了默认情况下通常禁用的WP\\U调试常量。我创建了一种方法，不仅可以启用WP\\u DEBUG，这样您就可以在实时站点上使用它，而不会产生负面的副作用，而且还可以使用其他调试常量来强制显示错误，并在/WP content目录中创建错误和通知的日志文件。

在wp配置中删除此代码。php文件（保存备份以防万一后），然后可以传递？debug=站点上任何URL末尾的1、2或3个参数。

?调试=1=显示所有错误/通知？调试=2=强制显示？调试=3=创建调试。/wp内容目录中所有错误的日志文件。

但这就是它变得更加棘手的地方。

自动将动态标题添加到公共页面Tested on:

使用下面的代码将根据公开查看的页面/帖子自动创建动态页面标题。

/* Dynamic Titles **/
// This sets your <title> depending on what page you\'re on, for better formatting and for SEO
// You need to set the variable $longd to some custom text at the beginning of the function
function dynamictitles() {
    $longd = __(\'Enter your longdescription here.\', \'texdomainstring\');
        if ( is_single() ) {
          wp_title(\'\');
          echo \' | \'.get_bloginfo(\'name\');

    } else if ( is_page() || is_paged() ) {
          bloginfo(\'name\');
          wp_title(\'|\');

    } else if ( is_author() ) {

将一个小部件放到“任意小部件”侧栏中，保存它，您将得到短代码：）

通过短代码获取自定义字段值

add_shortcode(\'field\', \'shortcode_field\');

function shortcode_field($atts){
  extract(shortcode_atts(array(
   \'post_id\' => NULL,
  ), $atts));

将编辑器默认设置为WYSIWYG或HTML

function my_default_editor() {
    $r = \'tinymce\'; // html or tinymce
    return $r;
}
add_filter( \'wp_default_editor\', \'my_default_editor\' );

Here is how to remove the HTML Editor

jQuery(document).ready(function($) {
$("#edButtonHTML").remove();
});

add_filter(\'wp_default_editor\', create_function(\'\', \'return "html";\'));

删除作者元数据库/选项（&O）；移动到发布MetaBoxTested on:

让我抓狂的事情之一是一个凌乱的Wordpress管理区。我现在总是从一开始就在函数中设置的元素之一。php文件正在删除作者元框和屏幕选项，然后将该选项添加到发布元框中。在我看来，这是有道理的，可以让事情保持干净。这也尊重适用的权限。

为了实现这一目标，只需将以下代码复制并传递到函数中即可。php文件。

如果您觉得有更好的方法，请提出建议。

注意：更新了代码以修复编码问题

// MOVE THE AUTHOR METABOX INTO THE PUBLISH METABOX
add_action( \'admin_menu\', \'remove_author_metabox\' );
add_action( \'post_submitbox_misc_actions\', \'move_author_to_publish_metabox\' );
function remove_author_metabox() {
    remove_meta_box( \'authordiv\', \'post\', \'normal\' );
}
function move_author_to_publish_metabox() {
    global $post_ID;
    $post = get_post( $post_ID );
    echo \'<div id="author" class="misc-pub-section" style="border-top-style:solid; border-top-width:1px; border-top-color:#EEEEEE; border-bottom-width:0px;">Author: \';
    post_author_meta_box( $post );
    echo \'</div>\';
}

快速确定服务器（&A）；环境详细信息

对于我的系统，环境由主机名的前3个字母决定，但这可以很容易地更改为适合您需要的任何字符。

add_action( \'admin_notices\', \'report_environment_status\', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname(\'n\');
    switch (strtolower(substr($server,0,3))) {
        case \'pXX\':
            $msg = "PRODUCTION";
            break;
        case \'qXX\':
            $msg = "QA";
            break;
        case \'dXX\':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = \'UNKNOWN\';
    }
    echo "<div id=\'update-nag\'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}

您还可以将其转换为插件并通过网络激活，以便所有站点都能收到通知。

延长自动注销时间Tested on:

使用下面的代码，您可以延长Cookie的保存时间，从而使登录的用户保持更长的登录时间：

function keep_me_logged_in_for_1_year( $expirein ) {
   return 31556926; // 1 year in seconds
}
add_filter( \'auth_cookie_expiration\', \'keep_me_logged_in_for_1_year\' );

添加一个“；“设置”；插件列表页面上的插件链接；“设置”；WordPress后端插件页面上的插件链接，方便用户使用跳转到设置（该代码还提供了WordPress版本2.9的解决方案）

// plugin definitions
define( \'FB_BASENAME\', plugin_basename( __FILE__ ) );
define( \'FB_BASEFOLDER\', plugin_basename( dirname( __FILE__ ) ) );
define( \'FB_FILENAME\', str_replace( FB_BASEFOLDER.\'/\', \'\', plugin_basename(__FILE__) ) );
function filter_plugin_meta($links, $file) {
  /* create link */
  if ( $file == FB_BASENAME ) {
    array_unshift(
      $links,
      sprintf( \'<a href="options-general.php?page=%s">%s</a>\', FB_FILENAME, __(\'Settings\') )
    );
  }
  return $links;
}

global $wp_version;
if ( version_compare( $wp_version, \'2.7alpha\', \'>\' ) ) {
    add_filter( \'plugin_action_links_\' . FB_WM_BASENAME, \'filter_plugin_meta\', 10, 2);
} else {
    add_filter( \'plugin_action_links\', \'filter_plugin_meta\', 10, 2 );
}

删除WordPress注释中URL的自动链接

remove_filter(\'comment_text\', \'make_clickable\', 9);

荣誉Rarst 对于无查询清理的代码

有条件地加载脚本这里有一种仅在存在特定短代码或小部件时加载脚本的方法。资料来源：Loading scripts only if a particular shortcode or widget is present

function has_my_shortcode($posts) {
    if ( empty($posts) )
        return $posts;
    $found = false;
    foreach ($posts as $post) {
        if ( stripos($post->post_content, \'[my_shortcode\') )
            $found = true;
            break;

    if ($found){
        $urljs = get_bloginfo( \'template_directory\' ).IMP_JS;
    wp_register_script(\'my_script\', $urljs.\'myscript.js\' );
    wp_print_scripts(\'my_script\');
}
    return $posts;
}
add_action(\'the_posts\', \'has_my_shortcode\');

And here is how to load scripts only if a certain widget is present

要在仅加载小部件的页面中加载脚本，必须在小部件类中添加is\\u active\\u widget（）代码。E、 例如，请参阅默认的最近评论小部件（wp includes/default-widgets.php，第602行）：

class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array(\'classname\' => \'widget_recent_comments\', \'description\' => __( \'The most recent comments\' ) );
        $this->WP_Widget(\'recent-comments\', __(\'Recent Comments\'), $widget_ops);
        $this->alt_option_name = \'widget_recent_comments\';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( \'wp_head\', array(&$this, \'recent_comments_style\') );
        add_action( \'comment_post\', array(&$this, \'flush_widget_cache\') );
        add_action( \'transition_comment_status\', array(&$this, \'flush_widget_cache\') );
    }

Remove Private and Protected Prefix此函数删除；Privite：“私人”；标记为私有的帖子和页面的前缀。仅对登录用户或组可见的内容有用。

function the_title_trim($title) {
$title = attribute_escape($title);
$findthese = array(
    \'#Protected:#\',
    \'#Private:#\'
);
$replacewith = array(
    \'\', // What to replace "Protected:" with
    \'\' // What to replace "Private:" with
);
$title = preg_replace($findthese, $replacewith, $title);
return $title;
}
add_filter(\'the_title\', \'the_title_trim\');

EDIT: 更新内容包括删除受保护的：以及。

Custom excerpt length

function excerpt($num) {
    $limit = $num+1;
    $excerpt = explode(\' \', get_the_excerpt(), $limit);
    array_pop($excerpt);
    $excerpt = implode(" ",$excerpt)."... (<a href=\'" .get_permalink($post->ID) ." \'>Read more</a>)";
    echo $excerpt;
}

例子：<?php excerpt(\'22\'); ?>这将限制摘录为22个字符。

摘录将被打断... (Read More)

    }
    return $classes;

在主页上显示来自不同自定义帖子类型的帖子，方法是将此帖子底部的以下代码拖放到您的函数中。php文件，您可以让wordpress自动显示您创建的不同自定义帖子类型的帖子。目前默认情况下，wordpress仅显示属于默认；“发布”；岗位类型。

在下面提供的示例中，您需要更改调用以下内容的部分：

$query->set( \'post_type\', array(\'post\', \'page\', \'services\', \'attachment\'));

使用您自己的自定义帖子类型，您希望将其包含在主页帖子列表结果中。在这种情况下，我们要求wordpress将属于默认设置的所有帖子返回给我们；“发布”；和；第“”页；post\\u type然后要求wordpress也包括我们为“创建的自定义帖子类型”；“服务”；最后是默认的wordpress帖子类型；附件“；这只是意味着，任何时候，只要有东西添加到媒体库中，它就会自动显示在主页上，作为一个单独的条目。

// CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( \'pre_get_posts\', \'my_homepage_post_list\' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars[\'suppress_filters\'] )
        $query->set( \'post_type\', array(\'post\', \'page\', \'services\', \'attachment\'));
    return $query;
}

您还可以在不同的位置使用此自定义查询，例如通过以下内容在自定义提要中使用

if (( is_home() && false == $query->query_vars[\'suppress_filters\'] ) || is_feed())

预填充帖子类型

////////////////////////////////////////////////////////////////////////////////////
// This auto populates post types and posts.
///////////////////////////////////////////////////////////////////////////////////

add_filter( \'default_content\', \'my_editor_content\' );

function my_editor_content( $content ) {

    global $post_type;

    switch( $post_type ) {
        case \'your_post_type_here\': //auto populate
            $content = \'The content you want to pre-populate the post type with.\';
break;
     }

    return $content;
}

自动包含谷歌分析代码Tested on: Wordpress 3.1 RC3

自WordPress 2.3.0以来，我一直在我的所有网站上使用此脚本。。。它只是将标准的谷歌跟踪脚本添加到页脚。

// Add Google Analytics Tracking Code
function add_google_analytics() {
?>
<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src=\'" + gaJsHost + "google-analytics.com/ga.js\' type=\'text/javascript\'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
    try {

        pageTracker._trackPageview();
    } catch(err) {}</script>
<?php
}

add_action(\'wp_footer\', \'add_google_analytics\');

只需确保更换UA-XXXXXXX-X 使用您自己的Google跟踪代码。。。

在所见即所得编辑器中添加“下一页”按钮

add_filter(\'mce_buttons\',\'wysiwyg_editor\');
function wysiwyg_editor($mce_buttons) {
    $pos = array_search(\'wp_more\',$mce_buttons,true);
    if ($pos !== false) {
        $tmp_buttons = array_slice($mce_buttons, 0, $pos+1);
        $tmp_buttons[] = \'wp_page\';
        $mce_buttons = array_merge($tmp_buttons, array_slice($mce_buttons, $pos+1));
    }
    return $mce_buttons;
}

向TinyMCE编辑器添加自定义样式有时用户和客户端会对其内容在编辑器中的显示方式与在前端的显示方式感到困惑。将主样式表中的一些相关行复制到新的tinymce中。css有很大帮助：

function custom_mce_css($wp) {
    return $wp .= \',\' . get_bloginfo(\'stylesheet_directory\') . \'/css/tinymce.css\';
}
add_filter( \'mce_css\', \'custom_mce_css\' );

function closeCommentsGlobaly($data) { return false; }
add_filter(\'comments_number\', \'closeCommentsGlobaly\');
add_filter(\'comments_open\', \'closeCommentsGlobaly\');
 <小时>
2. Give the administrator a different CSS class for the administrator\'s comments
if (1 == $comment->user_id)
    echo \'siteadmin\'; // Pick your class here
 <小时>
3. A really cool rich with a data list of comments - gr8 for custom locked page
$comments = get_comments( array(
    \'number\'    => 10, // How many comments
    \'status\'    => \'approve\' // Type of comments
) );

foreach($comments as $eachComment){

    // Collect the data and assign it
    $commentID = comment_ID;
    $commentAuthorEmail = $eachComment->comment_author_email;
    $commentPostId = $eachComment->comment_post_ID;
    $commentPostTitle = get_the_title( $commentPostId );
    $commentPostUrl = get_permalink( $commentPostId );
    $comment_sidebarnumber = get_comments_number( $commentPostId );

    global $wpdb;
    $userCommentCount = $wpdb->get_var(\'SELECT COUNT(\'.$commentID.\') FROM \' . $wpdb->comments. \' WHERE comment_author_email = "\' . $commentAuthorEmail . \'"\');

    echo \'<div style="border: 1px solid #ccc; padding: 10px;">\';

Create a conditional tag for custom taxonomies

    function has_student( $student, $_post = null ) {
    if ( !empty( $student ) )
        return false;
    if ( $_post )
        $_post = get_post( $_post );
    else
        $_post =& $GLOBALS[\'post\'];
    if ( !$_post )
        return false;
    $r = is_object_in_term( $_post->ID, \'studcat\', $student );
    if ( is_wp_error( $r ) )
        return false;
    return $r;
}

使WordPress编辑器允许iFrames

// make TinyMCE allow iframes
add_filter(\'tiny_mce_before_init\', create_function( \'$a\',
\'$a["extended_valid_elements"] = "iframe[id|class|title|style|align|frameborder|height|longdesc|marginheight|marginwidth|name|scrolling|src|width]"; return $a;\') );

    $new_page_template = \'\'; //ex. template-custom.php. Leave blank if you don\'t want a custom page template.

//don\'t edit under this line
$page_check = get_page_by_title($new_page_title);
$new_page = array(
    \'post_type\' => \'page\',
    \'post_title\' => $new_page_title,
    \'post_content\' => $new_page_content,
    \'post_status\' => \'publish\',
    \'post_author\' => 1,
);
if(!isset($page_check->ID)){
    $new_page_id = wp_insert_post($new_page);
    if(!empty($new_page_template)){

自动添加来自目录位置的标题图像，在wordpress附带的默认标题图像中，您会注意到一个额外的主题菜单，该菜单被激活，允许您选择要使用的标题图像。在默认主题代码中，这些图像被硬编码到函数中。php文件。下面的代码允许wordpress根据您可以直接在服务器（或主题文件夹）上创建的特定标题图像自动拾取新图像。

它将自动包括任何。jpg或。jpeg文件。每个图像都必须有一个关联的缩略图文件，但这只能是原始图像的一个副本，具有不同的名称，文件名必须以“结尾”-缩略图；。关联名称用作标题外观设置中的描述，下划线将自动替换为空格。（例如，My\\u Header\\u Image\\u A.jpg，My\\u Header\\u Image\\u A=缩略图。jpg将自动显示一个描述“My Header Image A”）

if ($handle = opendir( TEMPLATEPATH . \'/images/headers/\') ) {
    $headers = array();
    while (false !== ($file = readdir($handle))) {
        $pos = strrpos( $file, \'.\' );
        if( $pos !== false && $pos > 0 ) {
            $file_name = substr( $file, 0, $pos );
