发送帖子更改以设置电子邮件地址(不是用户或订阅者)

我现在使用的是“The Events Calendar“我的网站上的插件，用于协调员工团队。我希望能够自动发送包含活动帖子正文的电子邮件（帖子类型不是$post, 但是$tribe_events 相反）每次都会更新，但仅针对该职位相关的员工。

为了获取电子邮件地址，我在$tribe_events 根据我在网上找到的添加社交媒体按钮的插件发布type editor，效果很好：

add_action( \'add_meta_boxes\', \'add_custom_box\' );

function add_custom_box( $tribe_events ) {
    add_meta_box(
        \'animateurs\', // ID, should be a string.
        \'Animateurs\', // Meta Box Title.
        \'social_services\', // Your call back function, this is where your form field will go.
        \'tribe_events\', // The post type you want this to show up on, can be post, page, or custom post type.
        \'side\', // The placement of your meta box, can be normal or side.
        \'core\' // The priority in which this will be displayed.
    );
}

function social_services( $tribe_events )
{
// Get post meta value using the key from our save function in the second paramater.
$custom = get_post_meta($tribe_events->ID, \'_social_services\', true);

?>
    <input type="checkbox" id="anim_patrick" name="social_services[]" value="patrick@example.com" <?php echo (in_array(\'patrick@example.com\', $custom)) ? \'checked="checked"\' : \'\'; ?>>
    <label for="anim_patrick"></label>Patrick<br>

    <input type="checkbox" id="anim_jeff" name="social_services[]" value="jeff@example.com" <?php echo (in_array(\'jeff@example.com\', $custom)) ? \'checked="checked"\' : \'\'; ?>>
    <label for="anim_jeff"></label>Jeff<br>
<?php
}     

function save_extra_fields(){
global $post;

if(isset( $_POST[\'social_services\'] ))
{
    $custom = $_POST[\'social_services\'];
    $old_meta = get_post_meta($post->ID, \'_social_services\', true);
    // Update post meta
    if(!empty($old_meta)){
        update_post_meta($post->ID, \'_social_services\', $custom);
    } else {
        add_post_meta($post->ID, \'_social_services\', $custom, true);
    }
  }
// update_post_meta($post->ID, "producers", $_POST["producers"]);
}
add_action( \'save_post\', \'save_extra_fields\' );

The result

这将成功保存活动帖子所涉及的员工的电子邮件地址。

我可以使用此代码显示这些电子邮件地址的数组（在页面上-不是我想做的。这纯粹是为了显示如何从数组中获取电子邮件地址）：

<?php $meta = get_post_meta($post->ID, \'_social_services\', true); $anims = implode (", ", $meta); echo $anims; ?>

我需要的是最后一部分，那就是向中包含的电子邮件地址发送一封包含最新帖子内容的电子邮件$anims 每次$tribe_events 职位类型已更新。

我如何才能做到这一点？

PS：我是PHP的nube。这是我第一次尝试这样的事情。

/** * To send email on updating your event post * * @param int $post_id The post ID. * @param post $post The post object. * @param bool $update Whether this is an existing post being updated or not. */ function send_email_on_event_update( $post_id, $post, $update ) { $post_type = \'tribe_events\'; // your post type // If this isn\'t a \'tribe_events\' post, No need to send emails if ( $post_type != $post->post_type ) { return; } // - Now to Send emails // first get array of your emails $all_emails = get_post_meta($post_id , \'_social_services\', true); // this is suppose to be variable containing array of emails $post_title = get_the_title( $post_id ); $post_url = get_permalink( $post_id ); $subject = $post_title; $message = "This event has been updated:\\n\\n"; $message .= $post_title . ": " . $post_url; $message .= "keep adding what ever you want to send in this email..."; // Send email to $all_emails. wp_mail( $all_emails, $subject, $message ); } // have kept the priority to 11 to make sure we get the content for email after every thing is saved add_action( \'save_post\', \'send_email_on_event_update\', 11, 3 );

特定于某个主题的“Recent Posts”循环的帮助

我对WP越来越熟悉，但对PHP一无所知。我有一个网站正在www.wordpress-temporary上运行。我正在为客户开发的com。这是有一些定制的“二十一二”主题。我想做的是制作10页模板，每个练习区两个。每个练习区都有一个“主页”，其中显示特定于练习区的菜单以及该练习区主题的最新帖子。“内部页面”将添加一个谷歌新闻提要。我已经做了侧边栏业务。php和边栏商务主页。php插件到业务的页面模板文件夹中的相应文件。php和商务主页。php。我在想，因为在每个页面上都没有我想要的任何给定小部件，所以根本不
