Search By Multiple Checkbox, with AJAX div updating... where do I begin?
===

I'm hoping to create a fairly simple 'filter by multiple checkbox' search tool for a website... and I don't know where to begin with live updating results within a specified div as soon as someone selects/deselects a checkbox.

I hoping to build a filter system similar to this page:

... I want to have a system where clicking on each checkbox triggers a form submit, which loads results into a specified DIV on the same page.

Do you have any pointers towards, or code snippings, which could help me get started?


I am coding using PHP.

Thank you so much in advance for your help!
