Question

if ($resultdetails == FALSE) {
    $querynewid = "select * from customer_det order by ID desc limit 1";
    $resultnewid = mysql_query($querynewid);
    while ($row=mysql_fetch_row($resultnewid)) {
        $uid = $row['id'];
        echo $uid;
    }
}

Is this a valid nested statement to make? It won’t echo $uid for some reason?

Answer 1

You should use mysql_fetch_assoc instead of mysql_fetch_row. The last one returns a numerical indexed-array, so id is not a key in that result set. mysql_fetch_assoc returns an associative array, so the field name is also the name of the key. By the look of your code, that is what you want.

See the difference here and here.
