hook_view($node, $view_mode = 'full')

Display a node.

This is a hook used by node modules. It allows a module to define a custom method of displaying its nodes, usually by displaying extra information particular to that node type.

For a detailed usage example, see node_example.module.

Parameters

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

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

Return value

$node. 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.
