Whmcs auto auth - whmcs

Question

We are currently using auto auth and we have the method below to log in the user automatically using there email, the problem is when the email has a plus sign it will not login automatically.
/**
* #param $email Clients Email Address to Login
* #param string $goto is a url endpoint where you want to redirect the user
*/
public static function autoLoginUser( $email, $goto = 'index.php?m=dashboard' )
{
global $CONFIG;
/**
* Define WHMCS url and AuthKey from confguration.php
*/
$whmcsurl = $CONFIG['SystemURL'] . "/dologin.php";
$autoauthkey = "Our auth key is here"; //$autoauthkey from configuration.php
$timestamp = time(); //Get current timestamp
$hash = sha1($email . $timestamp . $autoauthkey); //Generate Hash
/**
* Generate AutoAuth URL & Redirect
*/
$url = $whmcsurl . "?email=$email&timestamp=$timestamp&hash=$hash&goto=" . urlencode($goto);
header("Location: $url");
exit;
}
Does anyone have tried this before? Having a normal email address works perfectly but on email that contains plus sign it won't log the user automatically.

Answer 1

I don't know why it was not documented in whmcs but the work around we manage to have is encode the email like the following code
/**
* #param $email Clients Email Address to Login
* #param string $goto is a url endpoint where you want to redirect the user
*/
public static function autoLoginUser( $email, $goto = 'index.php?m=dashboard' )
{
global $CONFIG;
/**
* Define WHMCS url and AuthKey from confguration.php
*/
$whmcsurl = $CONFIG['SystemURL'] . "/dologin.php";
$autoauthkey = "Our auth key is here"; //$autoauthkey from configuration.php
$timestamp = time(); //Get current timestamp
$hash = sha1($email . $timestamp . $autoauthkey); //Generate Hash
$email =
/**
* Generate AutoAuth URL & Redirect
*/
$url = $whmcsurl . "?email=".urlencode($email)."&timestamp=$timestamp&hash=$hash&goto=" . urlencode($goto);
header("Location: $url");
exit;
}
