Helper function to check whether the shortcode should be rendered or not.

Description

apply_filters( 'before_rtmedia_gallery_display', (unknown) $flag ); 

Parameters (1)

0. $flag (unknown)

The flag.

Usage

To run the hook, copy the example below.

$flag = apply_filters( 'before_rtmedia_gallery_display', $flag ); 
                         
if ( !empty( $flag ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the before_rtmedia_gallery_display callback 
function filter_before_rtmedia_gallery_display( $flag ) { 
    // make filter magic happen here... 
    return $flag; 
}; 
         
// add the filter 
add_filter( 'before_rtmedia_gallery_display', 'filter_before_rtmedia_gallery_display', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'before_rtmedia_gallery_display', 'filter_before_rtmedia_gallery_display', 10, 1 );
