Is it possible to call an extension method using an URL instead of a hook?

No, that’s what hooks are for. Moving to Dev.

So if I wat to call a function with an anchor or a form I will have to create a module for that?

Hooks are actually to be used in extensions. They allow to rewrite certain parts of EE, as it were, without the need to hack the original code.

Yeah.. but since you don’t have a hook to redirect after entry deletion.. and it’s not possible do redirect using the delete finish hook because then the entries are not really deleted.. the only option left, without hacking the core is to rewrite the delete_entries() function found in the content_edit.php controller.

The simplest solution would be to rewrite the delete function inside an extension. The problem is that I needed to call the function without using php or javascript code..

If there was a way to call the function using a url, I wouldn’t have to write a whole module just for that..
