[password textbox must match]

Another useful function is

 

      if(empty($login_Username) || empty($login_Password)) {
            throw new Exception("Error, Please enter your Username and Password!");
      }

[Calculating checkbox values]

Hi There,

 

I just wanted to share a really cool way of managing check boxes. For instance you could use them for user access functions etc

 

For you to read the values in PHP, this returns a true or false (1 or 0)

 

      public function checkAccess($required) { // The value of the box your after....e.g......64
            $m_access = $_SESSION['login_Access']; // This is where you store the checkbox value
            if ($required == 1 ) {
                  if($m_access & $required) {
                        return true;
                  }
            } else {			
                  if(($m_access & $required) / $required == 1) {
                        return true;
                  }
            }
      return false;
      }

 

or

 

      if((1024 & 64) / 64 == 1) {
            return true;
      }

 

This function will always return a unique value as per the box checked.

 

Hope people find it useful.

[PHP Cookies Help]

Thank you for your help, heres what i came up with, and appears to be really secure.

 

if($login_Remember) { /* Check if Remember Me was set */
         $sql = "UPDATE Users SET Session = '$session_id' WHERE id = " . $row['ID'];
         mysql_query($sql);
         setcookie('PDMS_SESSION', $session_id, time()+3600 * 24 * 30);
}

 

Then on every page i do a Session check, if that ok then it just returns true. Otherwise it'll check the cookie and and do an SQL query for that cookie

 

Public function doLoginCheck () {
         if(isset($_SESSION['login_ID'])) {
                  return true;
         }
         if(isset($_COOKIE['PDMS_SESSION'])) {
                  $query   = sprintf("SELECT users.* , user_groups.Value FROM users LEFT JOIN user_groups ON (users.Access = user_groups.ID) WHERE users.Session = '%s' LIMIT 0,1", $_COOKIE['PDMS_SESSION']);
                  $result  = mysql_query($query) or die('Error, Cookie check failed');
                  $row     = mysql_fetch_array($result, MYSQL_ASSOC);
                  $_SESSION['login_ID'] 	= $row['ID'];
                  $_SESSION['login_Name'] = $row['Name'];
                  $_SESSION['login_Access'] = $row['Value'];	
                  return true;
         }
         header("Location: login.php");
}

 

Seems to do the trick.

 

Thanks for your help.

[PHP Cookies Help]

Im trying to use the following code;

 

if($login_Remember) { /* Check if Remember Me was set */
      setcookie('login_ID', $row['ID'], time()+3600 * 24 * 30);
      setcookie('login_Name', $row['Name'], time()+3600 * 24 * 30);
      setcookie('login_Access', $row['Value'], time()+3600 * 24 * 30);
}
header("Location: index.php");

 

When i try to use it, the only cookie thats registered is the bottom on "login_Access". None of the others are. I have tried everything but nothings working.

 

I dont get any error messages.

 

Using PHP v5.3.3 on IIS

 

Please help.
