Session in php. It's not redirecting to the login page when a user wrongly inputs his information in the form -


when user correctly inserts information in login form redirects home page want i'm having problem when user inputs wrong info. shows connected , database selected. stops on page checklogin.php. if doesn't read session part. please go through code. here's code register form:

<?php $con=mysql_connect("localhost","root",""); if(!$con){ die('could not connect:' .mysql_error()); } echo "connected successfully."; $database=mysql_select_db('90210store'); if(!$database){ die('<br>could not select database:' .mysql_error()); } echo "<br>database selected";  $firstname=$_post['firstname']; //to information written in form $lastname=$_post['lastname']; $emailadd=$_post['emailadd']; $check_list=$_post['check_list']; $dob=$_post['dob']; $gender=$_post['gender']; $password=$_post['password'];  $first= "insert login     (firstname,lastname,emailadd,newsletter,dob,gender,password)     values     ('$firstname','$lastname','$emailadd','$check_list','$dob','$gender','$password')";  $result=mysql_query($first);  if($result){ echo('<br>data enterred successfully'); } else{ echo('<br>fail'); }   if($result) { header('location: phpredirectlogin.php'); }  mysql_close($con);  ?>

then page redirects to(phpredirectlogin.php):

<?php echo "<script>alert('redirecting login page');</script>"; echo "<script>window.location = 'account.html';</script>"; ?>

this php page checks login(checklogin.php):

<?php  $email=$_post['email']; $pwd=$_post['pwd'];  $con=mysql_connect("localhost","root",""); if(!$con){ die('could not connect:' .mysql_error()); } echo "connected successfully."; $database=mysql_select_db('90210store'); if(!$database){ die('<br>could not select database:' .mysql_error()); } echo "<br>database selected";  $result = mysql_query("select * login      emailadd='$email' , password='$pwd'") or  die('queryfailed:'.mysql_error());  while($row=mysql_fetch_array($result)) { session_start(); $_session['id']=1234; header('location:checklogin1.php'); } mysql_close($con); ?>

then page redirects user checklogin1.php.the code is:

<?php  session_start();  if(!isset($_session['id'])) { header('location:account.html'); } else { header('location:90210.html'); }  ?>

there has error somewhere can't seem figure out. appreciated. thank you.

change 

$result = mysql_query("select * login      emailadd='$email' , password='$pwd'") or  die('queryfailed:'.mysql_error());  while($row=mysql_fetch_array($result)) { session_start(); $_session['id']=1234; header('location:checklogin1.php'); }

to this

$result = mysql_query("select * login      emailadd='$email' , password='$pwd' limit 1") or  die('queryfailed:'.mysql_error());  if (mysql_num_rows($result) == 1 ) {     $_session['id']=1234;     header('location:checklogin1.php'); }

and session_start() right beginning of code.

moreover, redirect respective pages here have 1 redirect instead of 2 , rid of checklogin1.php. may edit above condition following:

if(mysql_num_rows($result) == 1) {         $_session['id']=1234;         header('location:90210.html'); } else {        header('location:account.html'); }
