function _signup_node_output in Signup 5.2

Same name and namespace in other branches

1. 6.2 includes/node_output.inc \_signup_node_output()
2. 6 includes/node_output.inc \_signup_node_output()
3. 7 includes/node_output.inc \_signup_node_output()

Generate all the signup-related output for a given node.

Because of the global setting to control if the signup details and form appear at the bottom of the node or on a separate tab, this function is shared by multiple callers.

@todo This needs to be much more theme-friendly.

Parameters

$node: The fully loaded node object.

$type: The kind of output would we render: can be either 'node' or 'tab'.

Return value

The fully rendered HTML for all signup-related forms and info.
