Exclude the current node from a list view
In some situations, for example a block listing nodes related to the node being viewed, you might wish to exclude the current node from a list view.
Using Views module, add a "Node:ID" argument type to your view. In the Option dropdown, select "Not Equal". Then place the following in the Argument Handling Code:
if ( ($type=='block') && is_numeric(arg(1)) ){
$args[0] = arg(1);
}
return $args;Adapted from this forum post: http://drupal.org/node/131482
Drupal 6 and higher
For Drupal 6+ (i.e. Views 2) no PHP is needed. http://drupal.org/node/328104#comment-1119773 gives the following method:
Use views arguments, assuming this is a block view
1. Add an argument for Node: nid
2. Set 'Action to take if argument is not present' to 'Provide default argument'
3. Set 'Default argument type' to 'Node ID from URL'
4. Check 'Exclude the argument'
