Outputting info on thank you page

[Ben]

Good questions!

(btw, the @ symbol just prevents any warnings from being outputted to the screen if the variable isn't defined).

Displaying the values in multi-select works like this. First, drop the [] characters. It's weird, I know, but they're only used when submitting the data via a form - it tells the server to expect an array of values. Try this instead:

PHP Code:

<?=join(", ", $fields["categories"])?>

It displays the values in $categories, separates by ", ".

And, if a field is left blank during the data entry, is there a way to conditionally make it so that nothing gets output on the thank you page?

Sure, here's an example.

Code:

<?php if (!empty($fields["first_name"])) { ?>
  First Name: <?=$fields["first_name"]?>
<?php } ?>

All the best -

Ben
