of course we can handle it in code,but not a good one....

other desciptions:

What he asks (I believe) is how to have 3 displays in one view and with [placeholder], [placeholder/versionone], [placeholder/versiontwo] URLs respectively and get a 404 on [placeholder/somethingrandom]. The second part of the URL does not seem to be an actual argument such as %nid. It's just a literal representation within the URL of what the display is meant to provide. :) @magtak

Answer 1

You can create two views. In one, using questions as URL, you add "Content: Nid" as contextual filter, and use the following settings for that contextual filter.

• In When the filter value is NOT in the URL

  • Select Display all results for the specified field

  

• In When the filter value IS in the URL or a default is provided

  • Select Specify validation criteria
  • As Validator, select Content
  • As Action to take if filter value does not validate select Show "Page not found"

  

The other view, using questions/mine as URL, would use "Content: Author uid" as criteria, and use a default value taken from the user currently logged-in.

Drupal 7 – Show page not found if view argument exists http://eureka.ykyuen.info/2012/02/24/drupal-7-show-page-not-found-if-view-argument-exists/ Posted on February 24, 2012 Assume we have a Views page which does not have a contextual filter setting and the view path is /eureka. If you provide an argument in the url such as /eureka/abc, the argument is ignored and the Views page will return all view rows. But sometimes we may want to show the user a page not found instead of return all rows. This can be done by adding a Global: Null argument in the contextual filter.

1. Add a Global: Null input in the View Contextual Filters settings.

2. Check the Specify validation criteria option and select PHP Code as validator.

if (empty($argument)) { return TRUE; } else { return FALSE; }

Done =)
