help with changing variable via form

[webguync]

Hi, I have a weather app, coded which creates weather based on a set zip code. I want to create a form which when the user fills out their local code and clicks the send button that will change the zip code variable. Currently it is set up like this

$zip = '90210'; //change to your zipcode

 

need help with getting started with this. Thanks!

Sounds like you know what to do.  Just assign $zip to the POST value after submission.  Maybe I'm misunderstanding.

so it would just be this?

<form method="post" action="<?php echo $PHP_SELF;?>">
Enter Zip Code:<input type="text" size="12" maxlength="12" name="zip"><br /> 

</form>

 

and then I would change

$zip='90210';
to
$zip= $_POST["zip"]

Try it out.
