LDAP身份验证失败时无法显示模式弹出窗口

I am working to validate users from LDAP via PHP. I have tried some code and I can now validate users perfectly. But in the case of an unsuccessful login, I want to display a modal popup with some custom message. Here is my code -

<?php


if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // username and password sent from form 

    $username = $_POST['username'];
    //print($username);
    $password = $_POST['password'];
    //print($password);
    // using ldap bind

    $ldaprdn  = 'uid=' .$username. ',ou=People,ou=AP,o=abcd.com'; // ldap rdn or dn
    $ldappass = $password;

    // connect to ldap server
    $ldapconn = ldap_connect("ad.abcd.com") or die("Could not connect to LDAP server.");

    if ($ldapconn) {

        try {
    $ldapbind = @ldap_bind($ldapconn, $ldaprdn, $ldappass);
} catch (Exception $e) {

    //echo "<script type='text/javascript'>$('#myModal').modal('show');</script>";
                //echo "<script type='text/javascript'>$('#myModal').fadeIn('show');</script>";
                echo "<script>
         $(window).load(function(){
             $('#myModal').modal('show');
         });
    </script>";
}
        if ($ldapbind) {

            $filter = '(sAMAccountName='.$username.')';
            $result = ldap_search($ldapconn, $ldaprdn, "(cn=*)") or exit("Unable to search LDAP server");
            $entries = ldap_get_entries($ldapconn, $result); 
            $userDN = $entries[0]["ikealegacyuid"][0];          

            echo ('<p style="color:green;">I have the user DN: '.$userDN.'</p>');
            $url = 'Location: logpage01.html?uid=' .$userDN;
            echo $url;
            header($url);
        } else {
         //echo "<script type='text/javascript'>$('#myModal').modal('show');</script>";
                //echo "<script type='text/javascript'>$('#myModal').fadeIn('show');</script>";
                echo "<script>
         $(window).load(function(){
             $('#myModal').modal('show');
         });
    </script>";
        }

    }

}
?>

      </div>

    </div>
  </div>

</div>

   </body>
</html>

I tried many solutions found here. But nothing worked. Need some help on this.

UPDATE: Checked Page Source Also. Seems it's fine. If not, please let me know the issue. enter image description here

I tried to call modal on page load also. It is working perfectly.

<script type="text/javascript">
    $(window).on('load',function(){
        $('#myModal').modal('show');
    });
</script>

    Just echoing the script won't work here, at best your browser will end up running a script that references $ before loading the html that loads jQuery, so even if it runs your script it will throw Uncaught ReferenceError: $ is not defined.

    Instead you can use a flag to tell the browser whether or not to show the modal. For example, you can set a variable in your else (and catch) statement :

    if ($ldapbind) { /*...*/ }
    else {
      $access_denied=1;
    }
    

    and insert it into the html so that the browser knows it must load the modal when access_denied===1, for this you also need to add the script that will load the modal only under that condition :

    <div id="myModal" access_denied="<?php print $access_denied ?>" > ... </div>
    <script> 
      $('#myModal[access_denied=1]').modal('show');
    </script>
    

    In another context using ajax requests you would probably just echo some json or output the modal html directly.

    If I see it correctly you are missing popper.js which is required in bootstrap. Please check this link https://getbootstrap.com/docs/4.3/getting-started/introduction/ and you will get an online cdn for popper which you can use. Or simply copy my snippet. Please also be aware that you are using bootstrap in version 3. I highly recommend using V4.

    In php you have to just echo the following when you want to show the modal.

    echo "<script>
                 $('#myModal').modal('show');
           </script>";
    

       $('#myModal').modal('show');
