post_format_rewrite_base filter

Filters the post formats rewrite base.

apply_filters( 'post_format_rewrite_base', string $context )


This filter hook called post_format_rewrite_base that allows you to overwrite the base.

In the core code, this hook looks like the following.

$post_format_base = apply_filters( 'post_format_rewrite_base', 'type' );

You’ll notice that the default base is type, which will give you post format archive URLs like

With the filter hook, it’s extremely easy to change this to something new. Suppose you wanted type to be types instead. Your plugin code would look like the following.

add_filter( 'post_format_rewrite_base', 'my_post_format_rewrite_base' );

function my_post_format_rewrite_base( $slug ) {
	return 'types';


  • $context : (string) Context of the rewrite base. Default ‘type’.

Live Example

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

 // define the post_format_rewrite_base callback 
function filter_post_format_rewrite_base( $type ) { 
// make filter magic happen here... 
return $type; 

// add the filter 
add_filter( 'post_format_rewrite_base', 'filter_post_format_rewrite_base', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'post_format_rewrite_base', 'filter_post_format_rewrite_base', 10, 1 );
