[pmwiki-users] Have a canonical url declaration : how to ?

[Petko Yotov]

Sorry, please use $HTMLHeaderFmt instead of $HTMLFooterFmt as below:

    if ($action == 'browse')
      $HTMLHeaderFmt['canonical'] = '<link rel="canonical" 
href="{$PageUrl}" />';

    # optional
    else $HTMLHeaderFmt['canonical'] =
      '<link rel="canonical" href="{$PageUrl}?action='.$action.'" />';
