Submitting Data via the Request Body: Reviving Functionality

Replacing GET with POST

Instead of $_GET['picture'] and $_GET['number'], we should use $_POST['picture'] and $_POST['number']. If you replace every occurrence of $_GET with $_POST inside pictures.php, everything should work again.

Unfortunately, using $_POST instead of $_GET breaks the integration with /random.php. As you may remember, it has a link to /pictures.php, and this link still adds a query parameter for the number of pictures to show. We can do two things:

1. Revert all the changes we made to /pictures.php: Remove the method="post" attribute, and go back to using query parameters and $_GET.
2. Add another form to /random.php, which also submits its data as a POST request with a request body.

Option 1 is easy, but option 2 will be more interesting, so let’s do that.
