Issue with $_POST and multiples forms

rakennedy75

I seem to be having an issue with $POST variable. I have multiple forms on my site with different sections but use the same variable name such as ... firstName or lastName. When I pass the forms to a php script I use the $POST variable to access the variable. Works fine until I access another form and when I use a script like this...

if($_POST['firstName == "") {....

than it isn't empty so it doesn't read this correctly.

is there a quick way to reset all post variables or will I have to manually clear them before I access the next form like this....

$POST['firstName'] == "";
$POST['lastName'] == "";
$_POST['address'] == "";

I hope this makes sense
any help would be appreciated, thanks

You can use the [man]unset[/man] language construct to unset the variables in the $_POST array after you are done with it.

For example, when you are done with the POST array in your form, do this:

unset($_POST);

This will empty the array for the next use.

ok, I am still haveing a little bit of an issue. That was the type of function I was looking for but it doesn't seem to fixing my issue so maybe there is another reason for it.

Here is what is happening. I am using a post form method of "post" when they post the first time it checks all there errors correctly but if I hit the back button and submit again it bypasses the errors for some reason, but it only seems to do it with specific forms. One is a drop down menu and the value in the default selection is -1. So when you go to the next page is has a statement like this...

if($_POST['leadSource'] == "-1")
{
      $error = "........";
}...

but the second time is still processes. Any idea why this might happen. Thanks for your help
