Usage

To run the hook, copy the example below.

$var = apply_filters( 'the_category', $var, $separator, $parents ); 
                         
if ( !empty( $var ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the the_category callback 
function filter_the_category( $var, $separator, $parents ) { 
    // make filter magic happen here... 
    return $var; 
}; 
         
// add the filter 
add_filter( 'the_category', 'filter_the_category', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'the_category', 'filter_the_category', 10, 3 );
