From your comment: Apparently the function can indeed not be used on the frontend in wp (see here), can anyone confirm this? I can confirm that the post_exists() function can be used on the front-end, but you need to manually load the file that defines the function, which is wp-admin/includes/post.php — see the “File: <path>” … Read more
When you select a page as your blog page, the template that WordPress is looking for is the home.php file. You should really check out the Template Hierarchy from the WordPress documentation as these things are really WordPress basic knowledge. Check out the Template Hierarchy here: https://developer.wordpress.org/themes/basics/template-hierarchy/
You can use is_paged() for this. This function determines whether the query is for a paged result and not for the first page. So ofcourse, in your case, you should use !is_paged(). Check out the docs here: https://developer.wordpress.org/reference/functions/is_paged/
I guess you need this function get_the_post_thumbnail_url($menu->object_id); (provided menu item is not a custom link) $menu->ID is not the id of the post/page it is linking to. About calling meta yes it is also possible $image_url = get_post_meta( $menu->object_id, ‘meta_key’, true );

This should also gate any other potential work-arounds, such as modifying the post through the REST API or direct POSTing. As an added benefit, it will … Read more

All you have to do is iterate the recent posts and add them one by one. add_action(‘admin_menu’, function () { $args = array( ‘post_type’ => ‘post’, ‘post_status’ => ‘publish’, ‘orderby’ => ‘post_date’, … Read more
One approach is to cast the objects as arrays. I recently had to do this in a project where I retrieved a list of articles and needed to display the featured image. There may be alternate ways to handle this issue, but I’ve found it to be reliable. Here is some relevant code from the … Read more
The default function that renders the categories meta box is post_categories_meta_box – it doesn’t have any internal hooks we can use to inject our own HTML, so let’s create our own meta box handler and just use the function internally: function wpse_406861_post_categories_meta_box( $post, $args ) { post_categories_meta_box( $post, $args ); echo <<<HTML <label> <input type=”checkbox” … Read more
You can check if post’s author has Administrator role like this (and output markup accordingly): if( author_can( get_the_ID(), ‘administrator’ ) ) { // author is admin } else { // author is not admin } See Roles and Capabilities if you want to check for something more specific than general role.
