[SOLVED] this.form.submit() won't go to the right page

[miseleigh]

I call the following from products.php:

<form action="http://www.mysite.com/products/bybrand.php" method="post">
          <select name="brand" onChange="this.form.submit()">
                        <option value="null"> Select Manufacturer </option>
                        <option value=1>Manufacturer 1</option>
                        <option value=2>Manufacturer 2</option>
                        <option value=3>Manufacturer 3</option>
          </select></form>

but when an option is selected, the page tries to go to products.html (which doesn't exist) instead of products/bybrand.php.  I have a few forms like this on products.php that are supposed to go to different pages, but they all do the same thing.  Any help would be greatly appreciated.

Well, nevermind... the original author had it redirecting back to the original products page if the varibale wasn't set and forgot to actually request it.  All fixed!

 

On products/bybrand.php:

<?php
  Header("Cache-Control: must-revalidate");

  $brand=$_REQUEST['brand'];  // I added this

  if(!isset($brand) || $brand == "null")
     header("Location: ../products.php");   //was originally products.html
