在不同页面，特定div中回显登录错误

Question

Delayed too long with this issue. I have a index.php including form and login.php handeling it.

How do I post the errors in a specific div in index.php? Here is the Index.php container, no php code in idnex.php yet.

    <div id="container">
    <section>
        <h1>ברוכים הבאים לאתר קופונים</h1>
        <h2>המקום בו תוכלו למצוא קופונים בסביבתכם</h2>
        <hr>
    </section>

    <section id="mainpage">
            <p class="welcome">
                אנא התחבר בכדי ליצור ולראות קופונים בקרבתך</br>
                <a href="php/register.php">הירשם לאתר</a> 
            </p>

            <form action="php/login.php" method="post" class="form">
                <p class="email">
                    <input type="text" name="email" /> :דואר אלקטרוני</br>
                </p>
                <p class="password">
                    <input type="password" name="password" /> :סיסמא</br>
                </p>
                <p class="submit">  
                    <input type="submit" value="היכנס" />  
                </p>  
            </form>
    </section>
</div>

and here is the login.php error reporting section

            //check matching input
        if($email == $dbemail && $password = $dbpassword){
            $_SESSION['email'] = $dbemail;
            include('../index.php');
            header('members.php');

        }
        else{
            include('../index.php');
            echo "Incorrect Password<style text-align:center;/>";
        }
    }

} else
    include('../index.php');
    die('<p class="error">User does not exist</p>');
} else
    include('../index.php');
    die('Please enter a Email and password');

tried this

include('../index.php');
    die('<p class="error">User does not exist</p>');

can't manage to specifically position it under the Submit button (using margin: 0 auto so left and right changes)

Thanks for any help given

Answer 1

change your login.php file:

} else {
   // error happened
   $error = '<p class="error">User does not exist</p>'
   include('../index.php');
   exit;
...

and your index.php file:

<form action="php/login.php" method="post" class="form">
<?php
if(isset($error)) echo $error;
?>
<p class="email">
   <input type="text" name="email" /> :דואר אלקטרוני</br>
...
