Best Practices & Usage Notes (if applicable): post_mime_types
When using the post_mime_types hook, it’s important to consider the security implications of allowing certain file types for a specific post type. Developers should carefully review and test the allowed mime types to ensure that only safe and necessary file types are permitted.
Usage Example: post_mime_types
“`php
function custom_post_mime_types( $post_mime_types ) {
$post_mime_types[‘video’] = array( ‘mp4’, ‘mov’, ‘avi’ );
return $post_mime_types;
}
add_filter( ‘post_mime_types’, ‘custom_post_mime_types’ );
