How to modify URL queries passed to view before its processed?

glass.dimly - June 14, 2009 - 19:59

So I've got a view that has takes a filter from an exposed form. The form doesn't pass the values gathered to the URL args, instead, it passes it as a query string to the URL. I need to ensure that this value is not over a certain number.

This is what the URL looks like:
http://forpeace.mayfirst.org/for-chapters-by-zip?distance[postal_code]=60626&distance[search_distance]=200&distance[search_units]=mile

This: ?distance[postal_code]=60626&distance[search_distance]=200&distance[search_units]=mile is not written to the args.

I need to ensure that the value passed to the view does not exceed 3285 miles because of this bug: http://drupal.org/node/471040

Any idea how to edit URL values before they are processed by the view?

I guess you could do it by implementing a hook like hook_views_pre_build, but I'm not 100% sure if it's possible and which hook you should use. See http://views.doc.logrus.com/group__views__hooks.html for a list of available hooks. Please follow up with your solution when you figure it out, I'd like to know!

Thanks for the docs link. I managed this by modifying the $GLOBAL variables inside a view template file.

Thanks fot the follow up, I didn't think of that solution. It feels a little hackish, but I guess that's allowed when you're doing a quick workaround for a bug :-)

Well....

...that's true, I'd prefer a more Drupalish way, but how can one get at the URL string if not through the $GLOBALS if it's not being written to the args?

Anyone?

I wouldn't worry about it,

I wouldn't worry about it, because the true problem is in the location module, not in the variables. The Drupalish way is to help fix the module and that's what you're doing.
