Short-circuit filter for wp_get_referer() during testing.

Allows tests to completely bypass wp_get_referer() and provide their own referer values. Only available during unit tests for security. Return a non-null value to short-circuit.

Auto-generated Example

add_filter(
   'gatherpress_pre_get_wp_referer',
    function( string|false $pre_value = null ) {
        // Your code here.
        return null;
    }
);

Parameters

• string|false|null $pre_value Pre-value to return instead of using wp_get_referer().
