title: How to display the welcome page after successful log in?
body: <p>I am using following code in two different folder like Model and View. In View Folder contain two php file like Login.php and Login_success.php. Controller folder contain the mysql database table field fetch code. When I run below code It can't display the Login_success page. Only the else field <strong>Check Name and password</strong> displayed. These all file combined to out of folder index.php .</p>
  
  <p>Here my code :</p>
  
  <p><strong>Login.php</strong></p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;Login&lt;/title&gt;
  &lt;link rel ='stylesheet' type = 'text/css' href = 'View/Design.css'&gt; 
  &lt;script&gt;
  function Validate(){
  var x=document.forms["login"]["username"].value;
  if (x==null || x=="")
    {
    alert("First name must be filled out");
    return false;
    }
   var x=document.forms["login"]["password"].value;
   if (x==null || x=="")
    {
     alert("Password must be filled out");
     return false;
    }
   }
   &lt;/script&gt;
   &lt;/head&gt;
   &lt;body&gt;
   &lt;form name = 'login' method = 'post' action = 'Controller/Controll.php' &gt;
   &lt;fieldset&gt;
   &lt;legend&gt;Login&lt;/legend&gt;
   User Name :&lt;input type = 'text' name = 'username'&gt;
   Password  :&lt;input type = 'password' name = 'password'&gt;&lt;br&gt;&lt;br&gt;
   &lt;input type = 'submit' name = 'submit' value = 'submit' onsubmit = "return Validate()" &gt;
   &lt;/fieldset&gt;
   &lt;/form&gt;
    &lt;/body&gt;
   &lt;/html&gt;
  </code></pre>
  
  <p><strong>Controll.php</strong></p>
  
  <pre><code> class Access{
   function connection(){
    require_once('View/Login.php');
   $con = mysql_connect('localhost','root','root');
   $db = mysql_select_db('Times_sheet');
   $query = mysql_query('select * from Login');
   $row = mysql_fetch_array($query);
   if(isset($_POST['submit']))
   {
    if(($row['UserName']==$_POST['username']) &amp;&amp; ($row['Password']==$_POST['password'])){
    require_once("View/Login_Success.php");
   }
    }
    else{
    echo "Check User name and Password";
   }
   }
   }
  </code></pre>
  
  <p><strong>Index.php</strong></p>
  
  <pre><code>require_once('Controller/Controll.php');
  class login extends Access{
  function getValu(){
  require_once('View/Login.php');
  }
   }
  $Obj = new login();
  $Obj -&gt;getValu();
  $Obj -&gt;connection();
  </code></pre>
  
  <p>When I enter the correct user name and password it shoes the empty page. I don't know what mistake I did.</p>
