Question

The result is always 1:

$sql = 'SELECT COUNT(Vote) FROM ' . $table;
$res = mysql_query($sql, $conn);
$vote_total = mysql_num_rows($res);

I ran the $sql query in phpMyAdmin and it returns 3, so the query is not the problem. $vote_total is initialized globally to 0, so that 1 is coming from somewhere. What other information do I need to provide to make helping me easier?

Thanks,

mysql_num_rows returns the number of selected rows and not the fields of a certain row. Use mysql_fetch_row to fetch the row you have selected with your query:

$sql = 'SELECT COUNT(Vote) FROM ' . $table;
$res = mysql_query($sql, $conn);
$row = mysql_fetch_row($res);
$vote_total = $row[0];

You could also use mysql_result to fetch a row and get a certain field:

$vote_total = mysql_result($res, 0, 0);

This fetches the first row (zero based) and returns the first field (zero based).
