Thanks !

I tried to PM you but didn't see how to - so here's my eMail address.

Looking forward to seeing the code. My GridBuilder.php, which I downloaded yesterday, doesn't have a SELECT DISTINCT statement. The code below is from line 200 - 207.
//where
		$conf_query = $this->translateWhereCond($this->_config->whereCond);
		if (("$conf_query"!="") && ($this->searchQuery!="")) {
			$where .= " WHERE (".$conf_query.") AND  ( $this->searchQuery )";
		} elseif ("$conf_query"!="") {
			$where .= " WHERE $conf_query";
		} elseif ("$this->searchQuery"!="") {
			$where .= " WHERE $this->searchQuery";

I'm using this in Joomla 1.5.15 on MySQL...

Thanks for sending the code along.

I see the SELECT DISTINCT statements, but am unsure how to implement the filtering.

I'm using grid to display CommunityBuilder users, and would like to only display users who are approved.

I tried adding a WHERE ('cb_fieldname' = '1') but it didn't seem to process....

Any insights would be most appreciated.

You should use different or no quotes for column name:
Correct:
WHERE (`cb_fieldname` = '1')
Correct:
WHERE (cb_fieldname = '1')

Wrong:
WHERE ('cb_fieldname' = '1')
How about posting a review on JED? Table JX, Card View JX, Paid Downloads JX

First, I really appreciate your help.

Second, I'm sorry for not being clearer in my question.

If you could share with me where you were able to enter your filter in the file you sent along, I think that would be most helpful.

Also, I noticed your code is quite different than the version I have. I just bought the component two days ago, and I get the feeling there have been updates.

Either way, if the code you sent can meet my needs with the hard coding of the filter I need, I'll happily use it.

Thanks again.
