将自定义值保存到帖子的主要内容

我创建一个元自定义输入来创建一个页面生成器。这样我就可以放下&；拖动元素以生成帖子的内容。

当我保存帖子时，我希望它能直接保存到帖子内容。

因此，我想我将更改$\\u POST并将其挂钩以保存\\u POST操作。

$_POST[\'content\'] = $_POST[\'page-builder-content\'];

我试过了，但没用。有什么建议吗？代码：

function stPageBuilder() {
    $screens = array(\'post\', \'page\');

    foreach ($screens as $screen) 
    {
        add_meta_box(
            \'st-post-class\',            // Unique ID
            esc_html__( \'Page Builder\', page-builder\' ),        // Title
            \'stPageBuilderCallBack\',        // Callback function
            $screen,                    // Admin page (or post type)
            \'advanced\',                 // Context
            \'default\'                   // Priority
        );
    }
}

function stPageBuilderCallBack($post, $box) {
    wp_nonce_field( basename( __FILE__ ), \'st-page-builder-nonce\' );
    // here is html layout for drag & drop feature
}

function stPageBuilderSave($postID) 
{
    if (\'page\' == $POST[\'post_type\']) {
        if (!current_user_can(\'edit_page\', $postID)) return;
    } else {
        if (!current_user_can(\'edit_post\', $postID)) return;
    }

    if (!isset($_POST[\'st-page-builder-nonce\']) || !wp_verify_nonce($_POST[\'st-page-builder-nonce\'], basename(__FILE__))) return;

    $_POST[\'content\'] = $_POST[\'st-page-builder-content\'];

}

function staddPageBuilder() {
    add_action( \'add_meta_boxes\', \'stPageBuilder\' );    
    add_action( \'save_post\', \'stPageBuilderSave\' );
}

staddPageBuilder();

// Hook to a different action / filter function staddPageBuilder() { // ... add_filter( \'wp_insert_post_data\', \'stPageBuilderSave\', 10, 2); } // Notice the new filter passes different arguments, so we need to adapt the function function stPageBuilderSave($data, $postarr) { // Since we don\'t have the $postID variable, let\'s try to grab it from the array passed by the insert function // Note that passing the object ID to the current_user_can function is very unusual and you can do without it $postID = isset($postarr[\'ID\']) ? $postarr[\'ID\'] : 0; if (\'page\' == $POST[\'post_type\']) { if (!current_user_can(\'edit_page\', $postID)) return; } else { if (!current_user_can(\'edit_post\', $postID)) return; } if (!isset($_POST[\'st-page-builder-nonce\']) || !wp_verify_nonce($_POST[\'st-page-builder-nonce\'], basename(__FILE__))) return; // This bit changes, because the action is different and so are the function\'s arguments $data[\'post_content\'] = $_POST[\'st-page-builder-content\']; return $data; }

// Create post object $my_post = array( \'post_title\' => \'My post\', \'post_content\' => \'This is my post.\', \'post_status\' => \'publish\', \'post_author\' => 1, \'post_category\' => array(8,39) ); // Insert the post into the database wp_insert_post( $my_post );
