Description

apply_filters( '<field_no_prefix>_edit_pre', (mixed) $value, (int) $post_id ); 

The dynamic portion(s) of the hook name refer to the post field name.

Parameters (2)

0. $value (mixed)

Value of the post field.

1. $post_id (int)

The post id.

Usage

To run the hook, copy the example below.

$value = apply_filters( '{$field_no_prefix}_edit_pre', $value, $post_id ); 
                         
if ( !empty( $value ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the <field_no_prefix>_edit_pre callback 
function filter_field_no_prefix_edit_pre( $value, $post_id ) { 
    // make filter magic happen here... 
    return $value; 
}; 
         
// add the filter 
add_filter( "{$field_no_prefix}_edit_pre", 'filter_field_no_prefix_edit_pre', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( "{$field_no_prefix}_edit_pre", 'filter_field_no_prefix_edit_pre', 10, 2 );
