Hooks in the middle of discussion list

MySchizoBuddy · March 2007

Is there a hook available that will allow me to add something in the middle of the discussion list. like something after the 5th Discussion or 5th Comment.

I would have to look to see about the discussion grid, but to put something after the 5th post, you could do something like this:

if ('comments.php' == $Context->SelfUrl) {
  Function TweenPost(&$CommentGrid)
  $RowNumber = &$CommentGrid->DelegateParameters['RowNumber'];
  $Comment = &$CommentGrid->DelegateParameters['Comment'];

  if ( 5 == $RowNumber ) {
    // close the existing CommentBody div, and open a new one that gets closed by the old div:
    $Comment->Body .= '</div><div class="TweenPost">' . $data;
  }
  $Context->AddToDelegate('CommentGrid', 'PreCommentOptionsRender', 'TweenPost');
}

Edit: Changed TweenPost($$CommentGrid) to TweenPost(&$CommentGrid)

You have to use for an extension: look at the document, and start by: http://lussumo.com/docs/doku.php?id=vanilla:development:gettingstarted

How do u pass the $data variable to TweenPost what will the AddDelegate thingy look like when u have to pass a variable to the function

MySchizoBuddy · April 2007

Any one?

Vincent · April 2007

all you do is make the variable at the start of your extension, then in the function, use this...

global $data;

MySchizoBuddy · April 2007

thats how i have done so far
but i have to do that for every single delegate I'm using. I was hoping to call the function with the data, which will make my code lot smaller than it is right now

Vincent · April 2007

then use call_user_func() or call_user_method()

MySchizoBuddy · April 2007

here are two functions that do 99% the same thing


function DisplayMenuNugget(&$Menu)
{
	global $NuggetObj;
	for ($i=0; $i < count($NuggetObj->Nugget); $i++)
	{
		if ($NuggetObj->Nugget[$i]['status']//check status
			&& in_array($Menu->Context->Session->User->RoleID, $NuggetObj->Nugget[$i]['roles']) // check roles
			&& in_array($Menu->Context->SelfUrl, $NuggetObj->Nugget[$i]['pages']) //check pages
			&& $NuggetObj->Nugget[$i]['position'] == 'MENU')
		{
			$NuggetObj->Nugget[$i]['html'] = AllowPHP($NuggetObj->Nugget[$i]['html']);
			if(!$NuggetObj->Nugget[$i]['hideName']) $DisplayNuggetString = '<h2>'.$NuggetObj->Nugget[$i]['name'].'</h2>';
			$DisplayNuggetString = '<div class="Nugget '.$NuggetObj->Nugget[$i]['position'].'">'.$DisplayNuggetString. $NuggetObj->Nugget[$i]['html'].'</div>';	
			echo $DisplayNuggetString;
		}
	}

}

$Context->AddToDelegate('Menu', 'PreBodyRender', 'DisplayMenuNugget');


function DisplayBelowPanelNugget(&$Panel)
{

	global $NuggetObj;

	for ($i=0; $i < count($NuggetObj->Nugget); $i++)
	{
		if ($NuggetObj->Nugget[$i]['status']//check status
			&& in_array($Panel->Context->Session->User->RoleID, $NuggetObj->Nugget[$i]['roles']) // check roles
			&& in_array($Panel->Context->SelfUrl, $NuggetObj->Nugget[$i]['pages']) //check pages
			&& $NuggetObj->Nugget[$i]['position'] == 'BELOW_PANEL')
		{
			$NuggetObj->Nugget[$i]['html'] = AllowPHP($NuggetObj->Nugget[$i]['html']);
			if(!$NuggetObj->Nugget[$i]['hideName']) $DisplayNuggetString = '<h2>'.$NuggetObj->Nugget[$i]['name'].'</h2>';
			$DisplayNuggetString = '<div class="Nugget '.$NuggetObj->Nugget[$i]['position'].'">'.$DisplayNuggetString. $NuggetObj->Nugget[$i]['html'].'</div>';	
			echo $DisplayNuggetString;
			
		}
	}
	
}
$Context->AddToDelegate('Panel', 'PostElementsRender', 'DisplayBelowPanelNugget');

I would like to just use one function, by passing appropriate parameters

Vincent · April 2007

What you have is completely fine. No excessive variables are made to go with each function so it doesn't run slower than it should. If your really desperate, you can add the '$NuggetObj' Object into the Context Object and have the render() function empty.

Howdy, Stranger!
