[RESOLVED] Getting the sum of database rows

Copy linkTweet thisAlerts:
Jul 31.2007

I have a function that needs to return the sum of selected rows of a database.

[code=php]
$query = mysql_query(‘SUM(image_size) FROM image WHERE user_id = “‘.mysql_real_escape_string($_SESSION[‘user_id’]).'”‘);
[/code]

I’m pretty sure that line of code works. I’m stumped as far as how to display the value. I tried return mysql_result($query); as well as a few other things, but nothing worked.

Thanks everyone!

@KingCobra220authorJul 31.2007 — I figured it out.
[code=php]
$query='SELECT SUM(image_size) FROM image WHERE user_id = "'.mysql_real_escape_string($_SESSION['user_id']).'"';
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_row( $result );
return $row[0];
[/code]

Success!
