Some issue with login credentials in php

Question

Below is my code for making a user login the page but when I tried to submit the form it does not check database and directly gives me the else output i.e invalid ID or password I am not getting any error reports too though error reporting is turned on I am not sure where am I going wrong here.

<?php
    if(isset($_POST['loginsubmit'])=='Login')
    {
        $email=$_POST['emaillogin'];
        $pass=$_POST['passlogin'];
        $pass=md5($pass);

        $email = stripslashes($email);
        $pass = stripslashes($pass);
        $email = mysql_real_escape_string($email);
        $pass = mysql_real_escape_string($pass);

        require_once "database.php";
        $sql = "SELECT * FROM user_log WHERE email = '$email' and password='$pass'";
        $loginresult=mysql_query($sql);
        $row=mysql_fetch_array($loginresult);
        $rowcnt=mysql_num_rows($loginresult);
        if($rowcnt==1)
        {
            session_start();
            $_SESSION['email']=$row['email'];
            $_SESSION['mobile']=$row['mobile'];
            $_SESSION['fname']=$row['fname'];
            $_SESSION['lname']=$row['lname'];
            echo "  <script>
                        window.location = '../';
                    </script>";
        }
        else
        {
            echo "  <script>
                        alert('Invalid Login ID or Password....');
                        window.location = '../';
                    </script>";
        }

I've even tried to echo wheather I am getting email and password properly from form and yes I was getting but issue starts from below line I guess:

$sql = "SELECT * FROM user_log WHERE email = '$email' and password='$pass'";

EDIT:FORM ADDED BELOW

<form action="" method="POST">
    <input type="email" id="email" placeholder="[email protected]" name="emaillogin" required>
    <input type='password' id='password' name='passlogin' placeholder='Password here' required>
    <input type="submit" id="continuesubmitemail" name="loginsubmit" value="Login">
</form>

isset() is used to check variable is set or not

You can check your condition as

 if(isset($_POST['loginsubmit']) && $_POST['loginsubmit']=='Login')

Also write session_start(); at the top of your page

Use while loop to get data

 $rowcnt=mysql_num_rows($loginresult);
        if($rowcnt==1)
        {
            while($row=mysql_fetch_array($loginresult))
            {
            $_SESSION['email']=$row['email'];
            $_SESSION['mobile']=$row['mobile'];
            $_SESSION['fname']=$row['fname'];
            $_SESSION['lname']=$row['lname'];
            }
            echo "  <script>
                        window.location = '../';
                    </script>";
        }

And finally stop using mysql it is deprecated . You can use PDO or mysqli
