Hi,

I'm converting one module from 5.x to 6.x

There is functionality to choose and create theming dynamically.

version 5.x looks something like this:

  $function = "theme_modulename_layout_$layout";
  if (function_exists($function)) {
    return theme("modulename_layout_$layout", $params);
  }

The problem is that with Drupal 6.x we've to register each function as theme_modulename_function_name in the function theme_modulename
But the function name comes dynamically depending on function existence.

How do I do that?

Thanks in advance.

$function = "theme_something";
if (function_exists($function)) {
return theme("something", $params);
}

There's a problem here in the first place. If I name my theme function 'garland_something', your code won't detect it. You should use theme_get_function() instead of function_exists().

To see how this is done in D6, have a look at 'drupal_render_form()', which is in 'form.inc'.

ya, but...

1. Drupal 6 no longer supports theme_get_function()

http://api.drupal.org/api/function/theme_get_function/5

2. Apart from that if my theme function name is 'garland_something', it would be called because it will override the 'theme_something', and 'theme_something' has to be exists.

Still the original question is still pending, I would like to register the theme function name dynamically with Drupal 6 theme registery.
