Hi!
Here i developed a login form using phpext. The problem exists when i
submit the form that i am including a javascript with Extjs code to
check if the login is ok or not.
Someone could help me to replace this code with native phpext code.
I will pubish all my avances using phpext here, since i am planing to
do a complete apllication using that framework.

Here is the code

<?php
$SITE = array();
$SITE["localhost"] = "http://".$_SERVER['HTTP_HOST'];
$SITE["root"] = str_replace("\\","/",$_SERVER['DOCUMENT_ROOT']);
$SITE["dir"] = str_replace("\\","/",dirname(__FILE__));
$SITE["base"] = str_replace($SITE["root"],$SITE["localhost"],
$SITE["dir"]);
// modulos
set_include_path(get_include_path().";".realpath("./library"));
