Are cp_css_end and cp_js_end available in 3.3.3

They work fine for me in 3.3.3. Have you looked in exp_extensions to make sure your extension is adding the right information to the database?

Thanks Pedro - I checked and it was added to exp_extensions.

It turns out it was firing. The issue was that I thought I could return a string of javascript code in the method that is called.

However, it looks as though the hook is designed to parse the contents of a file rather than parse a string directly from the method.

So, the following works for me now:

public function cp_js_end()
    {
        return file_get_contents( PATH_THIRD . '/sym_cloner/js/sym_cloner.js');
    }

You should be able to do either, file_get_contents returns a string after all.

Ok, thanks Pedro, I’ll retry the string bit. Thanks for your help.
