Strict warning: Only variables should be passed by reference in ...

Hrm-- I'm not exactly sure what I could do to change that. Those lines are both using Drupal 7 built-in functions. Ex:
569: $rtn .= drupal_render(drupal_get_form("arrange_fields_position_form", $form_id, $form_type));

To be fair, you are seeing "strict" warnings. Most production sites don't enable strict warnings. I'm not saying that's any excuse to be a lazy programmer, but usually "strict" is only enabled to help developers catch possible typos and things like that. If you don't think you'd miss them, I'd suggest just reducing your error_reporting level to only show standard warnings and errors.

But at any rate-- I'm not sure what I could do to prevent those, if anything. Anyone else out there have any ideas? Is this me, or Drupal core?

@richardp, the problem you are having is that you are passing the return of the function call "drupal_get_form" to drupal_render. drupal_render expects that parameter to be passed by reference. You can only pass a variable by reference NOT the return value of a function call.

Here is an example fix.

$temp_form = drupal_get_form("arrange_fields_position_form", $form_id, $form_type);
 $rtn .= drupal_render($temp_form);

You can apply this to all your drupal_render calls.

Oh, interesting. That's what I get for trying to combine too many functions in a row ;)

Thanks, I will try to have that change in my next release!

Okay, this is fixed in the 7.x-1.8 release. Should be avail for download within 10 minutes of this post.

Thanks!

#3 working fine :)

Thanks @tedbow.

Thanks, @tedbow! I split my variable (with much nail-biting as I am inexperienced with PHP) and did so successfully!
