Usage

To run the hook, copy the example below.

$var_fields = apply_filters( 'acf/export/clean_fields', $var_fields ); 
                         
if ( !empty( $var_fields ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the acf/export/clean_fields callback 
function filter_acf_export_clean_fields( $var_fields ) { 
    // make filter magic happen here... 
    return $var_fields; 
}; 
         
// add the filter 
add_filter( 'acf/export/clean_fields', 'filter_acf_export_clean_fields', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'acf/export/clean_fields', 'filter_acf_export_clean_fields', 10, 1 );
