PHP Radio button selection is pulling through blank?

Question

I am just trying to figure out why even though i have a value selected, my isset is pulling through that there is no data selected.

The HTML:

<form action="submitBackgroundImage.php" id="submitBackground">
      <input type="radio" name="background" value="lake" checked="checked"> Lake.jpg<br>
      <input type="radio" name="background" value="dock"> Dock.jpg<br>
      <input type="radio" name="background" value="forest"> Forest.jpg<br>
      <button type="submit" form="submitBackground" value="Submit">Submit</button>
</form>

The PHP in "submitBackgroundImage.php":

<?php

if (isset($_POST['background'])) {
    echo "Data Selected";
}
else
{
    echo "No Data Selected";
};

?>

This returns:

I'm a PHP novice so any advice is appreciated.

@FunkFortyNiner Is that built into PHP? or do you mean in the browser? — Luke Litherland, Sep 13 '18 at 12:26
Error reporting is built-in to the server's configuration file. If the server you're on doesn't let you modify that, then you can use the "catch and display" method as shown in the manual http://php.net/manual/en/function.error-reporting.php — Funk Forty Niner, Sep 13 '18 at 12:28
There is one thing though that everyone below missed and the fact of the matter is that, `
` defaults to a GET method if POST isn't specifically implied. *That* would have made for better answers, IMHO. — Funk Forty Niner, Sep 13 '18 at 12:29

You're missing the method.

<form action="submitBackgroundImage.php" id="submitBackground" method="POST">

Define the method in form element so that you will get the data when you submit the form

<form action="submitBackgroundImage.php" method="POST" id="submitBackground">
      <input type="radio" name="background" value="lake" checked="checked"> Lake.jpg<br>
      <input type="radio" name="background" value="dock"> Dock.jpg<br>
      <input type="radio" name="background" value="forest"> Forest.jpg<br>
      <button type="submit" form="submitBackground" value="Submit">Submit</button>
</form>
