How to use post_format_rewrite_base filter in WordPress

post_format_rewrite_base filter

Filters the post formats rewrite base.

apply_filters( 'post_format_rewrite_base', string $context )

Description

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 mydomain.com/type/post-format-slug.

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';
}

Parameters

• $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 );
