User refer url

[mudmin]

Ok. That makes sense. I will show you what to change and why it will help.

//I was assuming the user id was valid. Let's not do that.

Code:

$name = $db->query('SELECT username FROM users WHERE id = ?",array($ref))->first();

to

//make the query by itself

Code:

$nameQ = $db->query('SELECT username FROM users WHERE id = ?",array($ref));

//see if there are any results

Code:

$nameC = $nameQ->count();

if there are, grab the first (only) one

Code:

if($nameC > 0){

Code:

$name = $nameQ->first();

Code:

}

//Now, change the logic in your input class to only put in the value if there was one found when searching
//I'm going to share this as a pastebin link so I can space it out better without it being confusing.

If that isn't right, it's pretty close. I may have concatenated something wrong off the top of my head, but it's pretty close.
