How to have an empty post title and content when creating a new WordPress post via the front-end

0 Views

My aim is to insert a new draft post into the database via a custom front-end form I’ve created. I need the post title and content to be empty. Is this possible?

I’ve tried the following which doesn’t work:

$post_data = array(
    'post_title'    => '',
    'post_type'     => 'post',
    'post_content'  => '',
    'post_status'   => 'draft',
    'post_author'   => 1
);

$post_id = wp_insert_post( $post_data );

Note: You can create a new post using the back-end editor with empty title and content so I am wondering how they guys at WordPress do it.

  1. You can not insert a blank post with wp_insert_post, WordPress will prevent it with wp_insert_post_empty_content hook, you can see it in the source code : https://developer.wordpress.org/reference/functions/wp_insert_post/

    The only way to do it is to overpass this hook with a custom function

    Here is an example (source)

    add_filter('pre_post_title', 'wpse28021_mask_empty');
add_filter('pre_post_content', 'wpse28021_mask_empty');
function wpse28021_mask_empty($value)
{
    if ( empty($value) ) {
        return ' ';
    }
    return $value;
}

add_filter('wp_insert_post_data', 'wpse28021_unmask_empty');
function wpse28021_unmask_empty($data)
{
    if ( ' ' == $data['post_title'] ) {
        $data['post_title'] = '';
    }
    if ( ' ' == $data['post_content'] ) {
        $data['post_content'] = '';
    }
    return $data;
}
