* Retrieves a modified URL query string.
|
|||
|
|
*
|
|||
|
|
* You can rebuild the URL and append query variables to the URL query by using this function.
|
|||
|
|
* There are two ways to use this function; either a single key and value, or an associative array.
|
|||
|
|
*
|
|||
|
|
* Using a single key and value:
|
|||
|
|
*
|
|||
|
|
* add_query_arg( 'key', 'value', 'http://example.com' );
|
|||
|
|
*
|
|||
|
|
* Using an associative array:
|
|||
|
|
*
|
|||
|
|
* add_query_arg( array(
|
|||
|
|
* 'key1' => 'value1',
|
|||
|
|
* 'key2' => 'value2',
|
|||
|
|
* ), 'http://example.com' );
|
|||
|
|
*
|
|||
|
|
* Omitting the URL from either use results in the current URL being used
|
|||
|
|
* (the value of `$_SERVER['REQUEST_URI']`).
|
|||
|
|
*
|
|||
|
|
* Values are expected to be encoded appropriately with urlencode() or rawurlencode().
|
|||
|
|
*
|
|||
|
|
* Setting any query variable's value to boolean false removes the key (see remove_query_arg()).
|
|||
|
|
*
|
|||
|
|
* Important: The return value of add_query_arg() is not escaped by default. Output should be
|
|||
|
|
* late-escaped with esc_url() or similar to help prevent vulnerability to cross-site scripting
|
|||

* (XSS) attacks.
