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.

Übergabeparameter

$node The node to be displayed.

$teaser Whether we are to generate a "teaser" or summary of the node, rather than display the whole thing.

Rückgabewert

$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 in $node->content, rather than directly manipulating $node->body and $node->teaser. The format of this array is the same used by the Forms API. As with FormAPI arrays, the #weight property can be used to control the relative positions of added elements. If for some reason you need to change the body or teaser returned by node_prepare(), you can modify $node->content['body']['#value']. Note that this will be the un-rendered content. To modify the rendered output, see hook_node($op = 'alter').

For a detailed usage example, see node_example.module.
