Question

MyCode

$query = mysql_query("SELECT COUNT(`op_id`) FROM `room_group_options` WHERE `group` = '$group'");
echo $query;
$result = mysql_result($query, 0) ==  1) ? true : false;
if($result === true)
{
$error = 'already have this data';
}    

My code for checking already have data yet?, the problem is after run this code is the result always false, then I have try to echo $query and I got Resource id #11

How can I fix this problem?

Answer 1

mysql_query return a resource

and also change the condition as mysql_result return false on failure

so condition should be like this

$result = (FALSE !== mysql_result($query, 0)) ? TRUE : FALSE;

if you want to fetch from resource link so call

while ( $row = mysql_fetch_assoc($query))
{
  $fetch[]= $row;
}
