Filters the transient lifetime of the feed cache.

Description

apply_filters( 'wp_feed_cache_transient_lifetime', (int) $lifetime, (string) $filename ); 

Parameters (2)

0. $lifetime (int)

Cache duration in seconds. Default is 43200 seconds (12 hours).

1. $filename (string)

Unique identifier for the cache object.

Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

// define the wp_feed_cache_transient_lifetime callback 
function filter_wp_feed_cache_transient_lifetime( $lifetime, $filename ) { 
    // make filter magic happen here... 
    return $lifetime; 
}; 
         
// add the filter 
add_filter( 'wp_feed_cache_transient_lifetime', 'filter_wp_feed_cache_transient_lifetime', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'wp_feed_cache_transient_lifetime', 'filter_wp_feed_cache_transient_lifetime', 10, 2 );
