add_filter and added argument
-
Greetings
I’m trying to play wit hthe add_filter function
I did my homework reading
http://codex.ww.wp.xz.cn/Function_Reference/add_filterbut I face a problem when I want to pass more than one argument to the function that is target
I have a function as such
function populate_dropdown_destinations($form,$formID,$titleRemove,$sport_category){ here some code execution .... }I call it by
add_filter(“admin_pre_render”, “populate_dropdown_destinations”,10,4);but I have hard time to find where I put the $formID,$titleRemove,$sport_category values for those variable
I have try
apply_filters( ‘populate_dropdown_destinations’, $form, 2, ‘-test’, ‘test’);
but that is firing a big error
any idea where I can find some ressource to learn how to deal with added argument at the add-filter stage
thank you in advance
