pre_post_mime_type

The WordPress Core pre post mime type hook.

Description

add_filter( 'pre_post_mime_type', (string) $sanitize_mime_type ); 

Parameters (1)

0. $sanitize_mime_type (string) => 'sanitize_mime_type'

The sanitize mime type.

Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

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

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'pre_post_mime_type', 'filter_pre_post_mime_type', 10, 1 );
