Cant submit form

Basically I've got a form with 5 radio buttons. No submit button. I want the form to run when the user clicks on any of the radio buttons, so this is what I did.

<input id="5" type="radio" name="star" onchange="this.form.submit();" <?php if ($row["star"] =="5") echo "checked";?> value="5"/>

a querystring is required for the form so I'm using a form action like this

<form name="submit" action="http://example.com/page.php?id=<?php echo $urlid;?>&title=<?php echo $title;?>" method="POST">

and my php is 

if ($_POST["submit"]) {
    $rating = $_POST['star'];
    $title = $_GET['title'];
    $verification = ($_GET['verification']);
} else {
    //run the page like usual
}

After testing, I found that onclick, it runs the form action, but on the php side, it goes to "else" where is runs the page like usual instead. Any ideas?

Since you are checking with - 

if ($_POST["submit"]) { // this checks whether there is any item named 'submit' inside the POST or not
} else {
    //run the page like usual
}

The easiest would be to put a hidden item with name submit so that the check validates to true- 

<form .. >
     ....
     <input type='hidden' name='submit' value='submit' />
</form>

Your PHP is checking if $_POST['submit'] contains a value. Your form does not contain a form element with the attribute name="submit", so therefore it fails and moves straight to the else statement.

If you want to check if the form was posted then you should instead check for:

if (!empty($_POST)) {}

or

if ($_SERVER['REQUEST_METHOD'] == 'POST') {}

The form element seems to have invalid attributes, missing a quote and space.
It's generally easier to write a little more code, and keep it clearer

<?php
   $url = "http://example.com/page.php?id=". $urlid ."&title=". $title;
?>

<form name="submit" action="<?php echo $url; ?>" method="POST">
