How to get Twitter Bootstrap modals to stay open on form submit?

I am trying to figure out if there is a relatively simple way (I'm not very skilled at JQuery) to keep the modal open after a form submit. (The form is contained in the modal).

If the form is successful or there are errors, my PHP will show them but the modal closes as soon as the submit button is pressed.

If I reload the form, I can see the appropriate success or error message so all is working fine, but I'd prefer the end-user to see the message then click to close the modal afterwards.

I can post my code if that helps.

Thank you.

<?php
$success_message = "<h3 class='success'>Thank you, your message has been sent.</h3>";
$success = false; // we assume it and set to true if mail sent
$error = false;

// set and sanitize our form field values

$form = array(
'Name' => $sanitizer->text($input->post->name),
'Email' => $sanitizer->email($input->post->email),
'Phone number' => $sanitizer->text($input->post->phone),
'Type of client' => $sanitizer->text($input->post->client_type),
'Service client is after' => $sanitizer->text($input->post->service),
'Further information' => $sanitizer->textarea($input->post->information)
);

$required_fields = array(
'name' => $input->post->name,
'email' => $input->post->email
);


// check if the form was submitted
if($input->post->submit) {

// determine if any fields were ommitted or didn't validate
foreach($required_fields as $key => $value) {
if( trim($value) == '' ) {
$error_message = "<h3 class='error'>Please check that you have completed all the required fields.</h3>";
$error = true;
}
}
// if no errors, email the form results
if(!$error) {
$message = "";
$to_name = "My name";
$to = "me@me.com";
$subject = "Contact Form request";
$from_name = "My Website";
$from = "do-not-reply@my-site.com";
$headers = "From: $from_name <$from>";
foreach($form as $key => $value) $message .= "$key: $value\n";

require_once("./scripts/PHPMailer/class.phpmailer.php");

$mail = new PHPMailer();
$mail->CharSet = "UTF8";

$mail->FromName = $from_name;
$mail->From = $from;
$mail->AddAddress($to, $to_name);
$mail->Subject = $subject;
$mail->Body = $message;

if ($mail->Send()) {
$success = true;
}
}
}
?>

Answer

When you form is submitted, the page is reloaded, even if the action of the form is the same page (empty action means the same page too).

I think you want to re-open the modal once the page is loaded again. Guessing that you are using a method="post" form, your code should be something like that :

<html>
    <head>
      <!-- stuff -->
        <script type="text/javascript">

<?php if(isset($_POST['submit_button'])) { ?> /* Your (php) way of checking that the form has been submitted */

            $(function() {                       // On DOM ready
                $('#myModal').modal('show');     // Show the modal
            });

<?php } ?>                                    /* /form has been submitted */

        </script>
    </head>
    <body>
      <!-- etc -->
    </body>
 </html>
