PHP error: snippet-ops.php(582) : eval()’d code on line 5PHP message

Hi @ghsu292

Thanks for reaching out. The error message “Attempt to read property ‘ID’ on null” suggests that the code is trying to access an object’s ID property, but the object itself is null (i.e., it doesn’t exist at that moment).

Before accessing the ID property, you should check whether the object exists. For example if your snippet is trying to get the ID from a post like the following you could do something like this:

if ( get_queried_object() ) {
    $post_id = get_the_ID();
} else {
    $post_id = 0; // Or handle it appropriately
}

To help further, more details on what is attempted to being accessed would be helpful. In any case the above explanation will apply.

Hope this helps.
