I am trying to get a page view to show different information in the header depending on the arguments. How would I get the view args data via a php script in the header?

I would perfer not to use the args() function, as that seems too much of a hack, and would break if I ever use this view in a block.

Oh crap, I didn't restore the global variable stuff from Views 1. I will put that back in, since the only way to get data to the PHP filter is via globals.

Ok, finally checked this in -- views_set_current_view is now utilized during preview and execute_display; that should make it easy to use $view = views_get_current_view() during headers.

Re-opening the support request, I am unable to use this:

$view = views_get_current_view();
print (isset($view))?'TRUE':'FALSE';

The above code always prints false when set in the view header.

I did some debugging. While the $cache variable in views_set_current_view is set properly when called, it fails "isset" on the second call from views_get_current_view.

It looks like something is clearing it, but it is only called twice: one for the set, and one for the get.

I found the problem, it looks like the unset statement in views_set_current_view is removing the 'static' property of the variable.
The following code replacement works (line 3 commented out):

  if (isset($view)) {
    // be really safe with references here.
    //unset($cache);
    $cache = $view;
  }

Of course, you have the warning about references, I don't really know if this will cause Untold Bad Things to happen.

PHP confirms this: http://us3.php.net/unset

If a static variable is unset() inside of a function, unset() destroys the variable only in the context of the rest of a function. Following calls will restore the previous value of a variable.

Oh well hopefully the static nature will also cause it not to overwrite references then.

Ok, let's see if that does the trick.

It broke again...

You changed it to

$cache = &$view;

which isn't working on my site.

I changed it back to

$cache = $view;

and it started working again.

PHP really doesn't like this area of the module...

Bah! More reference pain. :/

Ah well. This will just have to have problems under PHP4, and that's all there is to it.

Running into this on Beta4, running PHP 5.1

Have some themes that make decisions on the view id

This has no value

global $current_view;

This returns true - but the print_r is empty

$view = views_get_current_view();
print (isset($view))?'TRUE':'FALSE';
print_r($view);

Thanks,
-Greg

It looks like attachments could unset the view early. I checked in a fix to -dev.
