form on the index page

[Kristoff]

Hello,

I have a little problem with form on the index page.

 

PrestaShop 1.4.3

index.tpl

{php}
$vat = $_POST['valE'];
echo $vat;
{/php}

<form method="POST" action="index.php">
<h1>Title</h1>
<p>Question?</p>
<input type="text" name="valE" onChange="this.form.submit(); return true;"/><br>
</form> 
{$HOOK_HOME}

This example run only if i use GET method, no POST. Why ?

I try also IndexController.php override, but situation is the same.

Do anyone have any idea ?

Thanks

Solution:

- should use Tools::getValue('value') instead of $_POST['value']

- action="index.php" change to action="{$base_url}"
