Does php support jquery. And if so is the following possible?? I also want to know if the following is possible using jquery. 1) I have certain search criteria in drop downlist box. 2) The first list box will be loaded when the page loads. 3) When a item is selected from the list the next drop down list should be filled in taking data from DB. But the page should be refreshed or loaded again. Is this possible??
Yes. PHP is executed before any output to the visitor. Javascript is client side code, so you can populate javascript, including jquery before the page is loaded. As far as changing values after a selection is made, the best method would be to make an ajax request to a back-end php script and then populate a new select box or other option for the user. You can also submit the page to a php form when the first selection is made and then populate a new form.
