Wordpress获取发布内容并升级页面

Question

我无法升级我的function.php以便：

检查是否有草稿

如果有内容，标题和类别

如果有一个title = post_category的页面升级页面的内容 使用post_content（和post_title）

否则创建一个title = post_category和content = post_content and post_title

的页面

代码

add_action( 'wp_insert_post', 'privatepostcheck' );

function privatepostcheck(){

    $args = array(
              'post_type' => 'post',
              'post_status' => 'draft'
              );
    // get the draft post         
    $posts_array = get_posts( $args ); 
    foreach($posts_array as $post){
        // foreach draft post get title, content and category
        $posttext = get_the_content($post);
        $postcate = get_the_category($post);
        $postitle = get_the_title($post);   

        //check if there is page with name = post category
        //get the page
        $page = get_page_by_title( $postcate );
        //get content
        $content_page = apply_filters('the_content', $page ->post_content);
        $content_post = apply_filters('the_content', $post->post_content);
        $page = array(
                'post_content' => "asidasoidjasoidjsaoi<br>".$content_page,
            );
        wp_update_post( $page );
}
