Creating CRON Job that needs to use PHP and HTML and even Javascipt

Dear Experts,

I want to use the cron functionality to run a tasks every hour, but from reading a few articles here I understand that cron can not execute HTML as it is not like viewing the page in a web browser. Because one of my scripts is updating multiple mysql rows, I need to use html and a submit button which can not be excecuted by CRON. I have looked at this article about using CGI bin to store the scripts that I can use CRON to execute the script in the CGI bin. Here is the link

Any help with this I would be very grateful. I need to include a submit button in the script file that will submit automatically when the page loads. Now I can achieve this with javascript but I do not think this will work as Javascript is not a server side language. ( can CGI execute javascript) or is there a way to have the html or php automatically submit the form once the page has loaded.

Again any suggestion that could help would be really helpful as I have almost no knowledge of CGI bin's capabilities or how to submit a form automatically once the page loads without using javascript.

many thanks as always for your help
