Bug in PHP - Request Superglobals

There seems to be an issue with the first instruction in HTML Form Handling in PHP - Request Superglobals. I am using print_r($var) to print the following superglobals:

  • $_REQUEST
  • $_GET
  • $_POST

I am passing in the above superglobals as arguments for print_r() in the designated spaces with the PHP tag, but it keeps asking if I used print_r() to print the $_REQUEST array. Maybe I am doing it wrong, but I can’t figure out any other possible solutions.

Hey there,

What does your code look like? Just to make sure :slight_smile:

So I had the same issue you did. I messed around for a while with no success, then I thought it might be possible that the PHP statement needed to be made all on the one line, (like the example below). That worked.

<?php print_r($var) ?>

I’m posting this for anyone in the future who gets stuck on this.

I’m guessing that you probably forgot a semicolon at the end of statement. It was like that in my case

Yes seems like it. It doesn’t work for me too until I have to remove the comment and write the php statement in one line for each. No idea why does it have to be this way.

7

I had this same error, all my code was correct, but when comparing my code with the solution, the side with my code was still displaying “#Print REQUEST data here” instead of what i’d written.

Refreshed the page a few times and pasted the same code back in and it worked after a couple of tries

For some reason, this one works only if you also remove the comments. Please add that to the instructions.

Even when it may not be required, one is still best to stick to the rule… Never leave out semi-colons.

    $_REQUEST:
    <?php print_r($_REQUEST); ?>
    <br>
    $_GET:
    <?php print_r($_GET); ?>
    <br>
    $_POST:
    <?php print_r($_POST); ?>

Was there a previous lesson where print_r was covered? I feel like I might have skipped over something. I just completed the intro course and started in on this one. It was not clear what I was supposed to do until I came here and saw the answer.

You have to remove the comment for the code to work.
