apply_filters( 'postmeta_form_limit', (int) $int ); 

Parameters (1)

Number of custom fields to retrieve. Default 30.

Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

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

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'postmeta_form_limit', 'filter_postmeta_form_limit', 10, 1 );
