Problem with submit button variable

GaryAC

I am having a problem with a variable of a submit button.

I check to see if the button has been pressed by:

if($add)

Which works howver, $add stays true, so even when I don't press it the code within this statement gets executed.

How can I reset the button variable to flase after it has executed the code??

Thanks for yoour help, this is really wining me up!!!

I don't know if if($add) is all you have or not. I'm going to assume so since that's all you posted.

You need to retrieve the form value either via $POST[] or $GET[] depending on the form method you are using. If you're using post, it would be: $add = $_POST['add'];

Once you have $add assigned to the form, you can then test it. If the form was not submitted, $add will be null. If the form was submitted, then its value will be "Add to Shopping Basket". These two values are not true/false. You have two options at this point: 1. test if null or "Add to Shopping Basket" - or - 2. Test if $POST['add'] has been set using isset() function: isset($POST['add']) <-- returns true/false which is what you're looking for.

Hallo,

you can validate the existens of a variable with "isset" and use "unset" to destroy a variable.

Read for both functions the doc. this helps a lot.
