cp_js_end referer

gistfile1.aw

<?php

class My_ext {

    /* blah blah blah */

    public function cp_js_end()
    {
        //be courteous to other users of this hook
        $str = $this->EE->extensions->last_call;

        $this->EE->load->helper('array');

        //we need to look at the referring page, this script is loaded in it's own request
        parse_str(parse_url(@$_SERVER['HTTP_REFERER'], PHP_URL_QUERY), $get);

        $controller = element('C', $get);

        $method = element('M', $get);

        if ($controller === 'content_publish' && $method === 'entry_form')
        {
            //bingo! we're on the publish page
            $str .= '
            $(document).ready(function(){
                //EMBIGGEN MY TITLE!
                $("input[name=title]").css("font-size", "80px");
            });
            ';
        }

        return $str;
    }
}

The script that is created using cp_js_end is loaded externally, which means that

<?php
if ($this->EE->input->get('C') === 'content_publish')

will not work as you might expect. You've got to look back to the referring page's query string to ascertain which CP page is currently loaded.

Missing a semi-colon after $method = element('M', $get) - was getting a white screen and just figured that out!

Beautiful.
