Question

I’m looking to label a string based on database results. I have the following code:

$loc1 = "A";
$query  = "SELECT loc FROM User where nick='".$users[$j]."'";
    $loc = mysql_query($query);
    if($loc == 1)
        $loc1 = "A";
    if($loc== 2)
        $loc1 = "B";

The loc1 location is always “A”. I’ve confirmed that the query works in MySQL and I’m having a difficult time understanding why this simple case is not working. I would appreciate your help!

The function mysql_query does not return the value of the column fetched, instead it returns a MySQL resource which you use to extract the column value returned by the query.

Change:

$loc = mysql_query($query);

to:

$result = mysql_query($query);
if (!$result) {
    die('Invalid query: ' . mysql_error());
}
if ($row = mysql_fetch_assoc($result)) {
    $loc = $row["loc"];
}
