Shishtawitch,

The code looks like it should work, however. two things .....

1. At the line $id_2 = $g["id"]; , surely $id_2 must be equal to $id because it comes from a row resulting from a query which returns rows where id=='$id' . If I'm right, then the second query doesn't need AND id!='$id_2' because that condition is already covered by AND id!='$id' .

2. The second query will return no rows if table has just one row or if in all rows id==$id .

Hey.

Just wanted to point out that number should not be quoted in MySQL queries. Can cause all sorts of problems.

Assuming your $id is in fact a number:

$query = mysql_query("SELECT * FROM table WHERE id != '$id' AND id!='$id_2'");
// Should be
$query = mysql_query("SELECT * FROM table WHERE id != $id AND id != $id_2");
