Solution 1

mysqli_query does not return a record set in all cases...see help page:http://php.net/manual/en/mysqli.query.php[^]
It is obvious in your case that you got somethin else than a result set. You have to debug to see what you got and check the reasons for it...I would look for an error...

I solve the problem, its my mistake...

PHP

<?php

include("includes/db.php");

    if(isset($_POST['login'])){

        $email = mysqli_real_escape_string($con,$_POST['email']);
        $password = mysqli_real_escape_string($con,$_POST['password']);

    $sel_user = "select * from jobseeker where email='$email' AND password='$password'";

    $run_user = mysqli_query($con, $sel_user);

     $check_user = mysqli_num_rows($run_user);

    if($check_user==1){

    $_SESSION['email']=$email;

    echo "<script>window.open('home_user.php?logged_in=You have successfully Logged in!','_self')</script>";

    }
    else {

    echo "<script>alert('Password or Email is wrong, try again!')</script>";

    }
    }

?>
