 Posted: Mon Apr 19, 2004 8:36 pm Post subject: Help with poll script |
 |
|
I'm working on a poll script, and for the one part I need to add up all the votes.
Heres the code for it:
| Code: |
//Mind this array for now...
$poll_option = array(
'1' => 'poll_option_1',
'2' => 'poll_option_2',
'3' => 'poll_option_3',
'4' => 'poll_option_4',
'5' => 'poll_option_5',
);
$poll_votes = array(
'1' => 'option_1_votes',
'2' => 'option_2_votes',
'3' => 'option_3_votes',
'4' => 'option_4_votes',
'5' => 'option_5_votes',
);
$poll_info = array(
'options' => $poll_option,
'num_votes' => $poll_votes,
);
$total = "0";
$increase_var_1 = "0";
$array_num = "1";
$sql_result = mysql_result($edit_sql_poll, 0, $poll_info['num_votes'][$array_num]);
while(mysql_result($edit_sql_poll, 0,"num_choices") > $increase_var_1) {
$total + $sql_result;
$increase_var_1++;
$array_num++;
}
|
For some reason the value of $total is always 0... It seems easy enough.[/code]

This line does nothing:
| Code: |
$total + $sql_result;
|
We guess that you meant:
| Code: |
$total += $sql_result;

some random person,
There is another problem with your code. You are using strings instead of integers. So replace:
| Code: | $total = "0";
$increase_var_1 = "0";
$array_num = "1";
$sql_result = mysql_result($edit_sql_poll, 0, $poll_info['num_votes'][$array_num]); |
with
| Code: | $total = 0;
$increase_var_1 = 0;
$array_num = 1;
$sql_result = intval(mysql_result($edit_sql_poll, 0, $poll_info['num_votes'][$array_num]));
