Action hook for custom tax edit

Question

So, i have a function in my template file functions.php which cache a search form that contain a custom taxonomie terms. I want to flush cache (or delete one cache group) when I add/delete/edit terms of a specific taxonomie.

Is it possible? maybe with do_action, but for which hook? thx

Answer 1

Look at wp-includes/taxonomy.php. The actions are:

• do_action("created_term", $term_id, $tt_id, $taxonomy);
• do_action("created_$taxonomy", $term_id, $tt_id);
• do_action("edited_term", $term_id, $tt_id, $taxonomy);
• do_action("edited_$taxonomy", $term_id, $tt_id);
• do_action('delete_term', $term, $tt_id, $taxonomy);
• do_action("delete_$taxonomy", $term, $tt_id);

Answer 2

You are looking for created_term, edited_term and delete_term. Each callback accepts 3 parameters:

function wpse_created_term( $term_id, $tt_id, $taxonomy ) {
}    
function wpse_edited_term( $term_id, $tt_id, $taxonomy ) {
}    
function wpse_delete_term( $term_id, $tt_id, $taxonomy ) {
}    

add_action( 'created_term', 'wpse_created_term', 10, 3 );
add_action( 'edited_term', 'wpse_edited_term', 10, 3 );
add_action( 'delete_term', 'wpse_delete_term', 10, 3 );
