Two different form action based upon a variable?

[vozzek]

Hi all,

 

Is it possible to have a form choose from two different possible actions (i.e. loading two different pages) based upon the value of a variable in php?

 

For example, let's assume my form looks like this:

 

<form ACTION="https://mywebsite.com/checkoutA.php" method="POST" name="pay_form" id="pay_form" onSubmit="return chkPayForm();" style="margin:0;">

 

Let's assume I have a variable called $total.  If $total>0 I would like the form to process onto the page checkoutA.php

 

But if the $total is not greater than zero, I would like the form to process onto the page checkoutB.php

 

How would I go about this?  Would I need to know the value of $total before the page gets to the html <form> code, and then optionally echo each possible outcome?  Or is there an easier way?

 

Thanks in advance, as always.

Okay, was afraid of that.

 

Thanks!

if u want it to be on the form itself, u can look at javascript validation. but dun rely on it, meaning keep a php validator in place.

Perhaps I missed something but couldn't you just run a switch in the one file so that based on the value of total you process the submited data in the same file but with two separate bits of code.

if ($total>0)
{
print "<form action="checkoutA.php>"
}
else
{
print "<form action="checkoutB.php>"
}

 

Or something along those lines.
