[PHP] PHP, Javascript, and Forms
Hi, I have a form with about 20 fields in it and have two drop down menus in which the second one changes depending on the previous one. This is done with a javascript which reloads the page. The problem with this is that everything the user has put in so far gets erased when the page reloads. I am using PHP sessions, but at this point these fields are not saved yet. Is there a way to do this using sessions, or some other PHP function. All the javascript I've looked at reloads the page. This also screws up my validation routines.

I think a better way for you to go(it may be a little bit more difficult, but it won't have any annoying flickering from the reloading of page) is to use AJAX. But if you insist on going on a PHP form + Javascript validation - submit form -PHP form + Javascript validation, that can be done as well. It might help to put up a sniplet of your PHP code. When you say the page is reloading, I assume that you mean you have a form tag that sends the POST data back to itself?

Javascript can do this easily, you set up your variable content section in a div. Then use div.innerHTML = newcontent. Only the content of the div will change. Searching for innerHTML should give you a few tutorials and full examples. David -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
