text field on a form

[Anon]

Hello,

I am having a problem submitting a simple html form to a php page...Here is the code

HTML FORM

<form action="index.php" method="POST">

<input type=text name=zip size="9"><input type=submit value=Go name=action>
</form>

INDEX.PHP

if (!$zip){
echo "Its working";
exit;
}
With the above example I will get an undeclared variable error. However if I change it to.

if (!$action){
echo "Its working";
exit;
}
It works fine. I also tried with a hidden field which also worked fine. Why wont the text field work?? win2k IIS5 PHP4.2

Thanks

why not just use:

if (isset($action)) or if (!empty($action))

why dont you try
if (!isSet($zip)){
echo "Its working";
exit;
}
or to check ithe value of zip also
if (!isSet($zip)){
if($zip == ""){
echo "Its working";
}
exit;
}

Dude---
You could change the method of your form to GET instead of POST and it might work.

Also, if your $zip variable is set, you want to check it by:
if ($zip){
do this if $zip is set....
}

if (!$zip){
do this if $zip is NOT set...
}

If nothing works try referencing the variable by $HTTP_POST_VARS[zip], because the variables are stored in the $HTTP_POST_VARS array.
