snippet return doesn't work, echo works but only once

Hi,

I have this setup

Modx 1.0.2

The template looks like


inside the template I have 2 calls to the same snippet



The snippet looks like



The file test-snippet.php is



The output of the template is




I see 2 problems:

1. return doesn’t work.
2. Only the first call is successful.

Any ideas why this is happening?

Thank you

It’s only running once because of include_once.
(Note that you don’t need brackets on include and require statements.)
You need to do the return from the snippet itself, not from the included file.
So in test-snippet.php, instead of the return statement, just set a variable, like $output = ’foo’;
Then return it from the main snippet code.

"You can’t return a value directly from an included file: because MODx treats Snippets as functions, it’s considered good form to always return a value, e.g. “return $output;” or “return TRUE;” but this MUST be returned from the original Snippet in the database; if you return output from the included file, you’ll have to return it again from the original database Snippet code. See the video for this quirk in action."

Using include instead of include once fixed the problem.

I’ll have a look at the video too.

Thx guys
