I have a login form and it works great but I need to add a script to it that will check for a registered email when you login and if you try to login with an email that isn't registered then it will show an error like "That isn't a registered email, try again".

 

Here is the code for my login

 

<?php

session_start();

include ('db_connect.php');

if(isset($_POST['submit']))
    {
    if(empty($_POST['email']))
        $error = 'Please fill in email field.';
    elseif(empty($_POST['password']))
        $error = 'Please fill in desired password field.';
    else
        {    
     
      // email and password sent from signup form
      $email=$_POST['email'];
      $password=$_POST['password'];
     
      $sql="SELECT * FROM users WHERE email='$email' and password='" . md5($password) . "'"; 
      $result=mysql_query($sql);
     
      // Mysql_num_row is counting table row
      $count=mysql_num_rows($result);
      // If result matched $email and $password, table row must be 1 row

      if($count==1)
      {
         // Register $email, $password and redirect to file "user.php"
         $_SESSION['hasLoggedIn'] = 1;

      //get the users id that is associated with him
       $SQL2 = "SELECT * FROM users WHERE email='$email'";
       $result2 = mysql_query($SQL);
       $row = mysql_fetch_assoc($result);

   //store the id in the session for use
       $_SESSION['userID'] = $row['id'];
      
         session_register("email");
         header("location:user.php");
      }
   }
}

?>

 

 

If anyone can help me with this that would be great.

 

-Thanks

I tried the above suggestions and I am getting this error.

 

Parse error: syntax error, unexpected T_ELSE in /home/mesquit1/public_html/local/login.php on line 44

 

Here is the code, did I put it in the wrong place or do something else wrong?

 

<?php

session_start();

include ('db_connect.php');

if(isset($_POST['submit']))
    {
    if(empty($_POST['email']))
        $error = 'Please fill in email field.';
    elseif(empty($_POST['password']))
        $error = 'Please fill in desired password field.';
    else
        {

      // email and password sent from signup form
      $email=$_POST['email'];
      $password=$_POST['password'];

      $sql="SELECT * FROM users WHERE email='$email' and password='" . md5($password) . "'";
      $result=mysql_query($sql);

      // Mysql_num_row is counting table row
      $count=mysql_num_rows($result);
      // If result matched $email and $password, table row must be 1 row

      if($count==1) {

         // Register $email, $password and redirect to file "user.php"
         $_SESSION['hasLoggedIn'] = 1;

      //get the users id that is associated with him
       $SQL2 = "SELECT * FROM users WHERE email='$email'";
       $result2 = mysql_query($SQL);
       $row = mysql_fetch_assoc($result);

   //store the id in the session for use
       $_SESSION['userID'] = $row['id'];

         session_register("email");
         header("location:user.php");
      }

        } else {

       $error = 'Wrong email or password, try again.';

      }
    }
  }

?>

 

-Thanks

You've got an extra curly bracket before your else

 

Try

 

      if($count==1) {

         // Register $email, $password and redirect to file "user.php"
         $_SESSION['hasLoggedIn'] = 1;

      //get the users id that is associated with him
       $SQL2 = "SELECT * FROM users WHERE email='$email'";
       $result2 = mysql_query($SQL);
       $row = mysql_fetch_assoc($result);

   //store the id in the session for use
       $_SESSION['userID'] = $row['id'];

         session_register("email");
         header("location:user.php");
      } else {

       $error = 'Wrong email or password, try again.';

      }

Ok I am getting this error now and I have played with it for a bit and can't get it to go away. Usally that means I haven't closed a bracket or have an extra one but they seemed to all be closed.

 

Parse error: syntax error, unexpected $end in /home/mesquit1/public_html/local/login.php on line 194

 

Here is the entire file. What am I missing or doing wrong?

 

<?php

session_start();

include ('db_connect.php');

if(isset($_POST['submit']))
    {
    if(empty($_POST['email']))
        $error = 'Please fill in email field.';
    elseif(empty($_POST['password']))
        $error = 'Please fill in desired password field.';
    else
        {

      // email and password sent from signup form
      $email=$_POST['email'];
      $password=$_POST['password'];

      $sql="SELECT * FROM users WHERE email='$email' and password='" . md5($password) . "'";
      $result=mysql_query($sql);

      // Mysql_num_row is counting table row
      $count=mysql_num_rows($result);
      // If result matched $email and $password, table row must be 1 row

      if($count==1) {

         // Register $email, $password and redirect to file "user.php"
         $_SESSION['hasLoggedIn'] = 1;

      //get the users id that is associated with him
       $SQL2 = "SELECT * FROM users WHERE email='$email'";
       $result2 = mysql_query($SQL);
       $row = mysql_fetch_assoc($result);

   //store the id in the session for use
       $_SESSION['userID'] = $row['id'];

         session_register("email");
         header("location:user.php");
      } else {

       $error = 'Wrong email or password, try again.';

      }
?>
