Php - When I require, it gives me a browsing error

Question

I have an input in a html file, wich as its form action on swag.php

<?php
header ('Location: ./teste.php');
$varr = $_POST['amount1'] ;

?>

I have teste.php

<?php 
require 'swag.php';

echo $var2;
?>

And then the input:

<form action="./post_swag/swag.php" method="post">
<input name="amount1" type="text" size="12" maxlength="4" />

<input type="submit">
</form>

When I insert the input's value, it gives me a browsig error, in teste.php, saying that it can't redirect me to the page because firefox detected that the server is rederecting a request to this adress for that the process is never concluded. And then it says that might be disabled cookies... What should I do?

Answer 1

The Location header tells the browser to stop what it's doing and load something else instead. So you have this:

1. browser requests swag.php

2. swag.php sends Location header telling the browser to load teste.php .

3. teste.php loads swag.php , which sends the Location header telling the browser to load teste.php

4. Repeat step 3 ad infinitum .

Firefox is detecting this infinite loop of redirects and says "I can't do that".
