How to run return to login file and run jQuery function from PHP if else statement

I have following PHP if/else statement - how can I tell it to go back to login.php and run jQuery function?

if($result) {
        if(mysql_num_rows($result) == 1) {

            //Login Successful
            session_regenerate_id();
       开发者_如何学运维     $member = mysql_fetch_assoc($result);
            $_SESSION['SESS_MEMBER_ID'] = $member['member_id'];
            $_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
            $_SESSION['SESS_LAST_NAME'] = $member['lastname'];
            $_SESSION['SESS_LOGIN'] = $member['login'];
            session_write_close();

            header("location: ../index.php");
            exit();
        }else {
            $error = true;
                    // go back to login.php and run jQuery function

            }
    }else {
        die("Query failed");
            // // or go back to login.php and run different jQuery function


    }

you could use:

header('Location: login.php?message=query_failed');

or

header('Location: login.php?message=login_failed');

and on your login.php inside your javascript tags:

you can use php for:

<?php if($_GET['message'] == 'query_failed'):  ?>

jquery_query_failed_function();

<?php elseif($_GET['message'] == 'login_failed'):  ?>

jquery_login_failed_function();

<?php endif; ?>

so Continuing from your else statement: it should be:

continuing from your else statement:

else {
        $error = true;
        header('Location: login.php?message=login_failed');

        }
}else {

    header('Location: login.php?message=query_failed');
    die("Query failed");
        // // or go back to login.php and run different jQuery function


}

header("Location: ../login.php?error_code=1");
header("Location: ../login.php?error_code=2");

Based on the error code you would execute a different function, that's if you wanna use redirects.
