提交表单后在同一页面上显示一条消息

Question

I have a simple HTML form with a name & email address field and a submit button.

After filling in the form and submitting it, I want a message such as "Thank you for your response" to appear on the same page.

I'm looking for a easy clean PHP fix for this. I want all the code to stay on one page (Not separate it into two different files).

I've been searching on Google, but they have much more complex situations.

Your help is greatly appreciated. Thanks.

EDIT: I want the form to disappear after pressing submit and just show the "Thank you for your response" message. I forgot to mention that. Sorry.

<form>
<p><span>Name</span><input class="contact" type="text" name="your_name" value="" /></p>
<p><span>Email Address</span><input class="contact" type="text"
name="your_email" value="" /></p>
<p style="padding-top: 15px"><span>&nbsp;</span><input class="submit"
type="submit" name="contact_submitted" value="submit" /></p>
</form>

Answer 1

please try below code.

<?php
if($_POST) {
    echo "Thank you for your response";
}
?>
<form name="test" action="" method="post">
<p><span>Name</span><input class="contact" type="text" name="your_name" value="" /></p>
<p><span>Email Address</span><input class="contact" type="text"
name="your_email" value="" /></p>
<p style="padding-top: 15px"><span>&nbsp;</span><input class="submit"
type="submit" name="contact_submitted" value="submit" /></p>
</form>

Would something like the following help? Essentially, when you hit submit, some special variables are set in the $_POST array, and you can access those. If those variables are set when we're building the page in PHP, then we can do some processing/send an email/show a different response page.

<?php
  if (array_key_exists($_POST['your_email'])) /* and other validation */ {
?>
<p>Thanks!</p>
<?php } else { ?>
<form action="POST">
<p><span>Name</span><input class="contact" type="text" name="your_name" value="" /></p>
<p><span>Email Address</span><input class="contact" type="text"
name="your_email" value="" /></p>
<p style="padding-top: 15px"><span>&nbsp;</span><input class="submit"
type="submit" name="contact_submitted" value="submit" /></p>
</form>
<?php } ?>

in you form validate page

header('location: ../page.php?case=Thank you for your response');

in your page

<?php print $_GET['case']; ?>
