Hiding div when is submitted and send values to PHP - php

Question

<?php
echo $_POST['textvalue'];
echo $_post['radiovalue'];
?>
<div id="hidethis">
<form method="POST" action="">
<label>Tekst Value</label>
<input type="text" name="textvalue">
<label>Radio Value</label>
<input type="radio" name="radiovalue" value="autogivevalue">
<input type="submit" id="submit" name="submit" value="submit">
</div>
http://jsfiddle.net/Bjk89/2/ here is it with the jQuery.
What i try to do is to hide the <div id="hidethis"> when it's clicking submit.
I know i can make another page where i can recieve the values without the <form> section, but i want to put both in one page, make the <div id="hidethis"> hidden after submit.
So i'll be able to get echo $_POST['textvalue']; and echo $_post['radiovalue']; as results
RESULT MUST BE LIKE
A Text // This is the value you input into Tekst Value
autogivevalue // This is the value from the radio button
----- INVISIBLE -----
<form is hidden because we set it in jQuery so>
</form>

Answer 1

Try this. No need to use jQuery here.
<?php
if($_POST) {
echo $_POST['textvalue'];
echo $_post['radiovalue'];
} else {
?>
<form method="POST" action="">
<label>Tekst Value</label>
<input type="text" name="textvalue">
<label>Radio Value</label>
<input type="radio" name="radiovalue" value="autogivevalue">
<input type="submit" id="submit" name="submit" value="submit">
</form>
<?php
}
?>

Try adding '#' in your jquery code. Your version does not have # next to submit. Also your form is missing a closing tag here and in your JSFiddle code.
Try this:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
$(document).ready(function () {
$('#submit').click(function () {
$('form').submit();
$('#hidethis').hide();
});
});
</script>
<form method='post' id="hidethis" name='form'>
<input type="text" name="textvalue">
<input type="radio" name="radiovalue" value="1">
<input type="button" id="submit" name="submit" value="submit">
</form>
