1.1.11
by Manuel Seelaus
new upstream release 4.4 |
742 |
* Retrieves a modified URL query string.
|
743 |
*
|
|
744 |
* You can rebuild the URL and append query variables to the URL query by using this function.
|
|
745 |
* There are two ways to use this function; either a single key and value, or an associative array.
|
|
746 |
*
|
|
747 |
* Using a single key and value:
|
|
748 |
*
|
|
749 |
* add_query_arg( 'key', 'value', 'http://example.com' );
|
|
750 |
*
|
|
751 |
* Using an associative array:
|
|
752 |
*
|
|
753 |
* add_query_arg( array(
|
|
754 |
* 'key1' => 'value1',
|
|
755 |
* 'key2' => 'value2',
|
|
756 |
* ), 'http://example.com' );
|
|
757 |
*
|
|
758 |
* Omitting the URL from either use results in the current URL being used
|
|
759 |
* (the value of `$_SERVER['REQUEST_URI']`).
|
|
760 |
*
|
|
761 |
* Values are expected to be encoded appropriately with urlencode() or rawurlencode().
|
|
762 |
*
|
|
763 |
* Setting any query variable's value to boolean false removes the key (see remove_query_arg()).
|
|
764 |
*
|
|
765 |
* Important: The return value of add_query_arg() is not escaped by default. Output should be
|
|
766 |
* late-escaped with esc_url() or similar to help prevent vulnerability to cross-site scripting
|
|
767 |
* (XSS) attacks.
