ACTION_HEADERS_SEND

Description:
modify the HTTP headers sent by Dokuwiki
DefaultAction:
output all the headers in order using the header() function
Preventable:
yes
Added:
2006-04-25

This event is signalled by act_dispatch() in inc/actions.php after preparing the headers and before loading the template.

Passed Data

The passed Doku_Event object has the fields: $data and $result.

The $data field is an array of header strings. This array has default one entry:

  • the DokuWiki header 'Content-Type: text/html; charset=utf-8'.

The BEFORE handler of this event can add/modify/delete the headers in the $data field. The event data must remain an array, even if emptied. The default action act_sendheaders() will output the headers, but this can be prevented by preventDefault().

The $result field is always null, because the default action don't set this field. The AFTER event handlers comes (default) after outputting the headers.
