PHP Warning Message

Hi guys,

I’m seeing a repeating warning being logged in my hosting portal. I pasted the error message into Claude and uploaded the plugin zip. It came up with a reasoning and solution for the error.

I asked Claude to write a post that I can copy/paste for you detailing the issue:

PHP Warning: Attempt to read property “post_type” on null — display.php line 312

Version: 4.2.4

Seeing the following in error logs:

PHP Warning: Attempt to read property "post_type" on null in /widget-options/includes/widgets/display.php on line 312

The issue is in the is_single() branch (~line 307). When the global $post is empty, the code calls get_post() as a fallback but doesn’t null-check the result before accessing ->post_type:

if (!$post) {
    $current_post = get_post();
    $type = $current_post->post_type; // Warning if get_post() returns null
}

get_post() can return null in certain contexts (REST API requests, some AJAX calls) where is_single() is true but no post object is available.

Suggested fix:

if (!$post) {
    $current_post = get_post();
    $type = $current_post ? $current_post->post_type : '';
}

Not a critical issue in terms of security, but it can cause widgets configured to show on specific post types to be incorrectly hidden when get_post() returns null. Also generates log noise and will surface as an error if display_errors is on.
