SqlBuilder Problem

Vincent · April 2007


function MakeFileAfterNewComment($Context) {
  $Comment = $Context->DelegateParameters['Comment'];
  if($Comment->WhisperUserID == false) {
    
    // Init SqlBuilder
    $s = $Context->ObjectFactory->NewContextObject($Context, 'SqlBuilder');
    
    // Get the Discussion Name
    $DiscussionID = $Comment->DiscussionID;
    $s->SetMainTable('Discussion', 'd');
    $s->AddSelect('Name', 'd');
    $s->AddWhere('d', 'DiscussionID', '', $DiscussionID, '=');
	$DiscussionName = $this->Context->Database->Execute($s, $Comment, '', 'An error occurred while finding a Discussion name.');			
    }
}

$Context->AddToDelegate('CommentManager','PreSaveNewComment','MakeFileAfterNewComment');

From that i get this...

Fatal error: Call to a member function SetMainTable() on a non-object in C:\Server\htdocs\Vanilla\extensions\Flash Updator\default.php on line 21

Any help? I'm trying to learn how to use the sqlbuilder...

I think all the SQLbuilder code is OK, but I don't believe the context object is passed to the function directly... thus the ObjectFactory doesn't build it properly.

Try this:

function MakeFileAfterNewComment($CommentManager) {
  $Comment = $CommentManager->Context->DelegateParameters['Comment'];
  if($Comment->WhisperUserID == false) {

    // Init SqlBuilder
    $s = $CommentManager->Context->ObjectFactory->NewContextObject($Context, 'SqlBuilder');

// ...

      $DiscussionName = $CommentManager->Context->Database->Execute($s, $Comment, '', 'An error occurred while finding a Discussion name.');

I can't even connect to the object factory through either my code or yours

Is your code included on a page where the CommentManager is created (ie. comments.php)?

Also, WallPhone missed one context reference. It should always be accessed through the object that was passed into the function:

function MakeFileAfterNewComment(&$CommentManager) {
   $Comment = $CommentManager->Context->DelegateParameters['Comment'];
   if ($Comment->WhisperUserID == false) {
    
       // Init SqlBuilder
       $s = $CommentManager->Context->ObjectFactory->NewContextObject($CommentManager->Context, 'SqlBuilder');
    
       // Get the Discussion Name
       $DiscussionID = $Comment->DiscussionID;
       $s->SetMainTable('Discussion', 'd');
       $s->AddSelect('Name', 'd');
       $s->AddWhere('d', 'DiscussionID', '', $DiscussionID, '=');
       $DiscussionName = $CommentManager->Context->Database->Execute($s, $Comment, '', 'An error occurred while finding a Discussion name.');			
    }
}

$Context->AddToDelegate('CommentManager','PreSaveNewComment','MakeFileAfterNewComment');

Well, that's what i get.... is something wrong here?

Another typo... Let's try this again:

function MakeFileAfterNewComment(&$CommentManager) {
   $Comment = $CommentManager->DelegateParameters['Comment'];
   if ($Comment->WhisperUserID == false) {
    
       // Init SqlBuilder
       $s = $CommentManager->Context->ObjectFactory->NewContextObject($CommentManager->Context, 'SqlBuilder');
    
       // Get the Discussion Name
       $DiscussionID = $Comment->DiscussionID;
       $s->SetMainTable('Discussion', 'd');
       $s->AddSelect('Name', 'd');
       $s->AddWhere('d', 'DiscussionID', '', $DiscussionID, '=');
       $ResultSet = $CommentManager->Context->Database->Select($s, $Comment, '', 'An error occurred while finding a Discussion name.');			
    }
}

$Context->AddToDelegate('CommentManager','PreSaveNewComment','MakeFileAfterNewComment');
