function hook_view

7.x node.api.php hook_view($node, $view_mode)

Display a node.

This hook is invoked only on the module that defines the node's content type (use hook_node_view() to act on all node views).

This hook is invoked during node viewing after the node is fully loaded, so that the node type module can define a custom method for display, or add to the default display.

Parameters

$node: The node to be displayed, as returned by node_load().

$view_mode: View mode, e.g. 'full', 'teaser', ...

Return value

The passed $node parameter should be modified as necessary and returned so it can be properly presented. Nodes are prepared for display by assembling a structured array, formatted as in the Form API, in $node->content. As with Form API arrays, the #weight property can be used to control the relative positions of added elements. After this hook is invoked, node_view() calls field_attach_view() to add field views to $node->content, and then invokes hook_node_view() and hook_node_view_alter(), so if you want to affect the final view of the node, you might consider implementing one of these hooks instead.
