* A walker class to use that extends wp_dropdown_categories and allows it to use the term's slug as a value rather than ID. | |
* | |
* See http://core.trac.wordpress.org/ticket/13258 | |
* | |
* Usage, as normal: | |
* wp_dropdown_categories($args); | |
* | |
* But specify the custom walker class, and (optionally) a 'id' or 'slug' for the 'value' parameter: | |
* $args=array('walker'=> new SH_Walker_TaxonomyDropdown(), 'value'=>'slug', .... ); | |
* wp_dropdown_categories($args); | |
* | |
* If the 'value' parameter is not set it will use term ID for categories, and the term's slug for other taxonomies in the value attribute of the term's <option>. | |
