Metabox重复字段-单选按钮未正确保存

时间：2014-02-21 作者：EHerman

我有多个单选按钮设置在一个自定义帖子类型的元框内。我创建了这样的元盒：

    add_action(\'admin_init\', \'add_meta_boxes\', 1);
    function add_meta_boxes() {
        add_meta_box( \'repeatable_fields\', \'Top 10 Movie List\', \'repeatable_meta_box_display\', \'cpt_top_ten_list\', \'normal\', \'default\');
    }

    function repeatable_meta_box_display() {
        global $post;
        $repeatable_fields = get_post_meta($post->ID, \'repeatable_fields\', true);
        wp_nonce_field( \'repeatable_meta_box_nonce\', \'repeatable_meta_box_nonce\' );

     if ( $repeatable_fields ) :

    // set a variable so we can append it to each row
    $num = 0;
    $second_num = 0;

    foreach ( $repeatable_fields as $field ) {
    $num++;

<div class=" playbackformat-holder-<?php echo $num; ?> playbackformat-holder">
    <form id="playback-form-<?php echo $num; ?>">
        <label for="dvd-<?php echo $num; ?>">
        <input type="radio" class="playbackformat-holder-radiobutton" value="dvd" name="playback_format[<?php echo $second_num; ?>]" id="dvd-<?php echo $num; ?>" <?php if($field[\'playback_format\'] == \'dvd\') { echo \'checked\'; } ?>>DVD
        </label>

        <label for="bluray-<?php echo $num; ?>">
        <input type="radio" class="playbackformat-holder-radiobutton" value="bluray" name="playback_format[<?php echo $second_num; ?>]" id="bluray-<?php echo $num; ?>" <?php if($field[\'playback_format\'] == \'bluray\') { echo \'checked\'; } ?>>Bluray
        </label><br>    

        <label for="3d-<?php echo $num; ?>">
        <input type="radio" class="playbackformat-holder-radiobutton" value="3d" name="playback_format[<?php echo $second_num; ?>]" id="3d-<?php echo $num; ?>" <?php if($field[\'playback_format\'] == \'3d\') { echo \'checked\'; } ?>>3d
        </label><br />
    </form>     
</div>
second_num++;
}
这是我的save函数，用于将数据存储到数组中。

add_action(\'save_post\', \'repeatable_meta_box_save\', 10, 2);
function repeatable_meta_box_save($post_id) {

    if ( ! isset( $_POST[\'repeatable_meta_box_nonce\'] ) ||
    !wp_verify_nonce( $_POST[\'repeatable_meta_box_nonce\'], \'repeatable_meta_box_nonce\' ) )
    return;

    if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE)
    return;

    if (!current_user_can(\'edit_post\', $post_id))
    return;

    $old = get_post_meta($post_id, \'repeatable_fields\', true);
    $new = array();

    $playbackFormats = $_POST[\'playback_format\'];


    $count = count( $names ) - 1;

    for ( $i = 0; $i < $count; $i++ ) {

    // currently only storing the last stored radio value
    $new[$i][\'playback_format\'] = $playbackFormats[$i];

    // save movie description
     // and however you want to sanitize
    if ( !empty( $new ) && $new != $old ) {
        update_post_meta( $post_id, \'repeatable_fields\', $new );
    } elseif ( empty($new) ) {
        delete_post_meta( $post_id, \'repeatable_fields\', $old );
    }

}
我面临的问题是，假设我有三排。如果将第一个设置为DVD，第二个设置为bluray，第三个设置为3D，则最后一个值存储为3D。所有其他[\'playback_format\'] 存储为“null”。

按照我的设置方式，似乎应该妥善保存。这是一个精简版。我有正确存储的输入字段，但单选按钮一直是一个主要问题。

看起来我的保存功能应该存储[\'playback_format\'] 在数组中的适当位置。但只有一家商店。我已经让它为所有三行存储相同的值，但无法为每一行获取唯一的值，也不知道为什么。

任何帮助都将不胜感激，因为这是拼图的最后一块！

谢谢（下面的屏幕截图提供了视觉帮助）

以下是var_dump($field); 将数据存储在上面的屏幕截图中之后。

array(4) {

所以我在练习后回到这里，实现了一些炼金术设置，这意味着所有输入都有如下名称name="_movies[3][title]" 其中3是循环中的迭代。

创建元框

// metaboxes should be registered on the add_meta_boxes hook
add_action(\'add_meta_boxes\', \'add_meta_boxes\' );
function add_meta_boxes() {
    add_meta_box( \'repeatable_fields\', \'Top 10 Movie List\', \'repeatable_meta_box_display\', \'cpt_top_ten_list\', \'normal\', \'default\');
}


function repeatable_meta_box_display( $post ) { 

$repeatable_fields = get_post_meta($post->ID, \'repeatable_fields\', true); 

if ( empty( $repeatable_fields ) ){
    $repeatable_fields[] = array ( 
                                \'image\' => \'\',
                                \'title\' => \'\',
                                \'playback_format\' => \'dvd\',

保存元现在相对容易，因为名称中的数组为我们设置了元：

add_action(\'save_post\', \'hhs_repeatable_meta_box_save\', 10, 2); 
function hhs_repeatable_meta_box_save($post_id) { 

if ( ! isset( $_POST[\'hhs_repeatable_meta_box_nonce\'] ) || 
!wp_verify_nonce( $_POST[\'hhs_repeatable_meta_box_nonce\'], \'hhs_repeatable_meta_box_nonce\' ) ) 
return; 

if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) 
return; 

if (!current_user_can(\'edit_post\', $post_id)) 
return; 

$clean = array(); 

if  ( isset ( $_POST[\'_movies\'] ) && is_array( $_POST[\'_movies\'] ) ) :

    foreach ( $_POST[\'_movies\'] as $i => $movie ){

    // skip the hidden "to copy" div
    if( $i == \'%s\' ){ 
        continue;
    }

$playback_formats = array ( \'dvd\', \'bluray\', \'3d\' );

    $clean[] = array( 
        \'image\' => isset( $movie[\'image\'] ) ? sanitize_text_field( $movie[\'image\'] ) : null,
        \'title\' => isset( $movie[\'title\'] ) ? sanitize_text_field( $movie[\'title\'] ) : null,
        \'playback_format\' => isset( $movie[\'playback_format\'] ) && in_array( $movie[\'playback_format\'], $playback_formats ) ? $movie[\'playback_format\'] : null,
        \'description\' => isset( $movie[\'description\'] ) ? sanitize_text_field( $movie[\'description\'] ) : null,
        );

}

endif;

// save movie data 
if ( ! empty( $clean ) ) { 
    update_post_meta( $post_id, \'repeatable_fields\', $clean ); 
} else
    delete_post_meta( $post_id, \'repeatable_fields\' ); 
}
我会说，我遇到了我们在聊天中谈到的同一个问题。。。。在经历了这一切之后，我仍然在运行第二台和第三台“playback\\u格式”收音机，而不是晚间发布的时候，我几乎疯了。但最后，我注意到你正在用<form> 要素我确信这就是问题所在，因为我一摆脱它，它就奏效了。

我建议你试着减少额外的<Form> 首先查看代码，看看这是否解决了问题。这可能是您的其余代码工作。如果不是，那么我很确定我的现在是。。。然而，我已经更改了一些名称和ID，因此这可能会影响依赖于此的其余工作。

最后，关于我是如何改变一切的，我需要修改你的添加行JS。这里进行了简化，因为我不想处理tinyMCE编辑器，所以我只留下文本区域用于测试目的。

使用Javascript复制行

/*********************** Add Row Button Click *****************************/ 

$( \'#add-row\' ).click(function() { 
var rowCount = $(\'#repeatable-fieldset-one\').find(\'.single-movie-row\').not(\':last-child\').size(); 
var newRowCount = rowCount + 1;

var row = $( \'.empty-row.screen-reader-text\' ).clone(true); 

// Loop through all inputs
row.find(\'input, textarea, label\').each(function(){ 

    if ( !! $(this).attr(\'id\') )
        $(this).attr(\'id\',  $(this).attr(\'id\').replace(\'[%s]\', \'[\' + newRowCount + \']\') );  // Replace for

    if ( !! $(this).attr(\'name\') )

    if ( !! $(this).attr(\'for\') )
        $(this).attr(\'for\',  $(this).attr(\'for\').replace(\'[%s]\', \'[\' + newRowCount + \']\') );  // Replace for

});

row.removeClass( \'empty-row screen-reader-text\' ).find(\'.movie_rank_number\').val(\'# \'+newRowCount);
row.insertBefore( \'.empty-row\' ); 

// if row count hits 10, hide the add row button 
if ( newRowCount == 10 ) { 
jQuery(\'#add-row\').fadeOut(); 
} 

return false; 
});

结束

DO_ShortCode()不会返回PHP数组

我做了一个短代码[get_clients] 它应该在通过调用时返回所有客户端的数组do_shortcode(\'[get_clients]\'). 但它只返回一个字符串“Array”。为什么？
