How to show post title in content editor in backend?

Question

Is this possible? I am trying to use a pre-defined template for my contents. To do that, I use something like this:

add_filter( 'default_content', 'custom_editor_content' );
function custom_editor_content( $content ) {

     $args = array(
        'posts_per_page'=> 15,   
        'orderby'  => array( 
                'ID' => 'DESC' ,
            ),
    );
    $query = new WP_Query( $args );
    $query_contents=Array();

    while ( $query->have_posts() ) {
        $query->the_post();
        array_push($query_contents,Array(
            "id"=>get_the_ID(),
            "title"=>get_the_title(),
            "url"=>get_permalink(),
        ));

    }
    $content = '



    '.get_the_title( $id ).'


    ';
   return $content;
}

But I can't get the post, somehow. Does someone know how to do this? If I put the while statement into $content, it shows the whole query in the editor and that's not what I want of course.

All I want to do is to fetch the post title and show it in the content editor (after posting or before, that wouldn't matter)

Could someone help me out?

Answer 1

$id isn't set anywhere in your code snippet. get_the_title( null ); returns an empty string. If you want the title of a post, you'll need to set $id to a proper post ID.

(Also, $args) is unset in the code you've posted, and I don't see anywhere that you use query_contents either.)
