Re: [PHP] Help with PHP processing form checkboxes needed :-(
Hi there, Thanks to everyone who replied about the checkboxes, I must have had brainrott or something as the answer was so simple - just delete the entries for the items on the page and put them back in again. Simple and works like a charm :-) Regards Chris Payne - Original Message - From: "kranthi" To: "Michael A.

The way I handle something like this is to give the checkbox tag a "value" attribute. Like: Each page has to be a form if you do this. When you check the form, look for $_POST['mixer'] == 'ordered_mixer'. If that relation is true, the user left the box checked. If it's not true, the user unchecked the box. Don't hold me to this. Do an experiment and see if that doesn't work. I'm operating from memory, and I could be wrong. Paul That's basically what I do except I don't care what value is sent so I set the value to 1, a value won't be set if isn't checked, so I just check to see if the _POST['whatever'] is set or not. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi everyone,
I'm having a major problem. I have an order system that allows you to
add items with a checkbox, that works fine. If you add an item and go
back to the product listing the items that are in your cart show up as
checked on the products listing forms to make it easier to see what you
have in your cart.
My problem comes here:
I have been asked that if you have items in your cart and people are
browsing your products, when they see it checked (Because they added it
earlier) - well, basically they want to be able to uncheck it from there
and delete it from the database, how the heck can I do this? When you
check a box it's easy as it sends it's id but if you don't check one it
doesn't send any data or am I missing something?
Please be gentle with me as this is confusing the heck out of me :-)
if (isset($_POST['someitem'])) {
$someitem_checked = true;
} else {
$someitem_checked = false;
}
Regards
Chris
