自定义元框Save_Post函数中未触发回调.php



子主题,函数.php,我正在创建一个元框。我在自定义元框中有两个文本字段。每当用户从管理员添加帖子单击"更新"或"发布"时,我都需要保存字段。允许此元框出现在盟友类型的帖子中,包括自定义帖子。

我正在运行PHP7.3,运行wordpress 5.3

我尝试:1)使用其他钩子,如save_edit_post,admin_init,publish_post等。

2) 为add_Action提供优先价值

3) 审查了 HTTP post 请求以确认元键值对正在传递 - 是的。

4) 使用 get_post_meta() 和$POST全局变量来测试值是否通过 - 但无法验证。

function add_taddressbox_address_meta_box() {
    add_meta_box(
        'taddressbox_address_meta_box', // $id
        'taddressbox Address', // $title
        'show_taddressbox_address_meta_box', // $callback
        get_current_screen(), // $screen
        'normal', // $context
        'high' // $priority
    );
}
function taddressbox_address_save_postdata($post_id, $post, $update)
{
    //if this is post revision, then bail
   if (wp_is_post_revision( $post_id))
   {
       return;
   }
    // if our current user can't edit this post, bail  
    if( !current_user_can( 'edit_post' ) ) return;  

  $lat_val = sanitize_text_field(get_post_meta($post_id, '_taddressbox_lng', true));
    //get_post_meta($post->ID, 'taddressbox_lat', true);
    $lng_val = sanitize_text_field(get_post_meta($post_id, '_taddressbox_lng', true));
    update_post_meta($post_id, '_taddressbox_lat', $lat_val);   
    update_post_meta($post_id, '_taddressbox_lng', $lng_val);

}

function show_taddressbox_address_meta_box() {
    global $post;  
//   $values = get_post_custom( $post->ID );
    $lat = isset( $values['taddressbox_lat'] ) ? trim(esc_attr( $values['taddressbox_lat'][0] )) : '30'; 
    $lng = isset( $values['taddressbox_lng'] ) ? trim(esc_attr( $values['taddressbox_lng'][0] )) : '69';
//$lat = '30';
//$lng ='69';
    //  $meta = get_post_meta( $post->ID, 'taddressbox_address', true );
        ?>
    <input type="hidden" name="taddressbox_address_box_nonce" value="<?php echo wp_create_nonce( basename(__FILE__) ); ?>">
    <!-- All fields will go here -->
    <div id="map" tabindex="0" style="position: relative;height:400px;margin:0; padding:0; display: block;"></div>
    <div id="taddressbox_latlng">
     <label for"latitude">Latitude</label> <input type="text" id="taddressbox_lat" name="taddressbox_lat" value="<?php echo $lat; ?>">
      <label for"longitude">Longitude</label> <input type="text" id="taddressbox_lng" name ="taddressbox_lng" value="<?php echo $lng; ?>">
    </div>
<script>

<?php if ( trim($lat) == '' || trim($lng) =='' ) { ?> InitializetaddressboxMap();
<?php  } else {  ?>
InitializetaddressboxMap(<?php echo $lat; ?>,<?php echo $lng; ?>);    
<?php } ?>
</script>
    <?php  }

您必须使用 $_POST[] 来捕获并保存表单提交的代码。我已经修复了您的代码,请随意使用它。

add_action( 'add_meta_boxes', 'add_taddressbox_address_meta_box' );
    function add_taddressbox_address_meta_box() {
        add_meta_box(
            'taddressbox_address_meta_box', // $id
            'taddressbox Address', // $title
            'show_taddressbox_address_meta_box', // $callback
            get_current_screen(), // $screen
            'normal', // $context
            'high' // $priority
        );
    }

    add_action( 'save_post', 'taddressbox_address_save_postdata' );
    function taddressbox_address_save_postdata( $post_id )
    {
        //if this is post revision, then bail
       if (wp_is_post_revision( $post_id))
       {
           return;
       }
        // if our current user can't edit this post, bail  
        if( !current_user_can( 'edit_post' ) ) return;  
        if ( ! isset( $_POST['my_lat_lang_box_nonce'] ) ) {
            return $post_id;
        }
        $nonce = $_POST['my_lat_lang_box_nonce'];
        // Verify that the nonce is valid.
        if ( ! wp_verify_nonce( $nonce, 'my_lat_lang_box' ) ) {
            return $post_id;
        }
        $lat_val = sanitize_text_field($_POST['taddressbox_lat']);
        $lng_val = sanitize_text_field($_POST['taddressbox_lng']);
        update_post_meta($post_id, '_taddressbox_lat', $lat_val);   
        update_post_meta($post_id, '_taddressbox_lng', $lng_val);

    }

    function show_taddressbox_address_meta_box( $post ) {
        $lat = get_post_meta( $post->ID, '_taddressbox_lat', true );
        $lng = get_post_meta( $post->ID, '_taddressbox_lng', true );

        wp_nonce_field( 'my_lat_lang_box', 'my_lat_lang_box_nonce' );
         ?>
