Usage

To run the hook, copy the example below.

$image_attachment = apply_filters( 'attachment_thumbnail_args', $image_attachment, $metadata, $uploaded ); 
                         
if ( !empty( $image_attachment ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the attachment_thumbnail_args callback 
function filter_attachment_thumbnail_args( $image_attachment, $metadata, $uploaded ) { 
    // make filter magic happen here... 
    return $image_attachment; 
}; 
         
// add the filter 
add_filter( 'attachment_thumbnail_args', 'filter_attachment_thumbnail_args', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'attachment_thumbnail_args', 'filter_attachment_thumbnail_args', 10, 3 );
