Wrong Datatype in bbcode_class file

[Cyricx]

Okay, so I'm trying to work the usergroup smilies hack to be more secure by replacing the smilies with text instead of the image if the smilie is in a particular category (102) and the user is not in the secondary usergroup (44).

I've tried the below, and I'm getting an error for "wrong data type in second argument"

Any ideas?

// ##### START HACK - Usergroup Smilies #####
if ($smilie['imagecategoryid'] == "102")
{
  if (in_array("44", $this->registry->userinfo['membergroupids']))
  {
	if ($this->is_wysiwyg())
	{
	 $replace = "<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\" title=\"$smilie[title]\" smilieid=\"$smilie[smilieid]\" class=\"inlineimg\" />";
	}
	else
	{
	 $replace = "<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\" title=\"$smilie[title]\" class=\"inlineimg\" />";
	}
  }
  else
  {
 $replace = "*censored_smilie*";
  }
}
else
{
// ##### END HACK - Usergroup Smilies #####
 
	// if you change this HTML tag, make sure you change the smilie remover in code/php/html tag handlers!
	if ($this->is_wysiwyg())
	{
	 $replace = "<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\" title=\"$smilie[title]\" smilieid=\"$smilie[smilieid]\" class=\"inlineimg\" />";
	}
	else
	{
	 $replace = "<img src=\"$smilie[smiliepath]\" border=\"0\" alt=\"\" title=\"$smilie[title]\" class=\"inlineimg\" />";
	}
 
// ##### START HACK - Usergroup Smilies #####
}
// ##### END HACK - Usergroup Smilies #####
   $sc["$find"] = $replace;

I'm trying to hardcode in the category and usergroup numbers first.

Thanks so much for any help
