Hi zusammen Wink

Kennt ihr die funktion round() ?
Also ich habe keine Ahnung davon. Sad

Ich hab da ein Code von einem umfrage script,
wo müsste ich den jetzt diese round() funktion eifügen ?
Und wie mache ich das überhaupt ?

PHP-Code:
<?php
// Daten für Verbindung zur Datenbank
$dbhost = " * ";
$dbuser = " * ";
$dbpassword = " * ";
$dbdatabase = " * ";

// Präfix
$prefix = " * ";
define(TABLE_PREFIX, $prefix);
// URL zum Forum

// Url zur polls.php deines Forums - Bitte nur bis Zum Urdner!
$url =" * ";
// lang Variabeln:
$lang_poll ="";
$lang_total_votes ="St";

// Verbindung zur Datenbank aufnehmen
$db = mysql_connect($dbhost,$dbuser,$dbpassword) or die ("Verbindung fehlgeschlagen");
mysql_select_db($dbdatabase,$db);

$query = mysql_query("SELECT * FROM ".TABLE_PREFIX."polls WHERE extpoll='1' ORDER by pid desc");
$poll = mysql_fetch_array($query);
$poll['timeout'] = $poll['timeout']*60*60*24;
$expiretime = $poll['dateline'] + $poll['timeout'];
$now = time();
if($poll['closed'] == "yes" || ($expiretime < $now && $poll['timeout'] > 0))
{
    $showresults = 1;
};
$query = mysql_query("SELECT * FROM ".TABLE_PREFIX."pollvotes WHERE pid='".$poll[pid]."'");
while($votecheck = mysql_fetch_array($query))
{
    $alreadyvoted = 1;
    $votedfor[$votecheck['voteoption']] = 1;
}
$optionsarray = explode("||~|~||", $poll['options']);
$votesarray = explode("||~|~||", $poll['votes']);
for($i=1;$i<=$poll['numoptions'];$i++) {
    $poll['totvotes'] = $poll['totvotes'] + $votesarray[$i-1];
}
$poll['question'] = addslashes($poll['question']);
for($i=1;$i<=$poll['numoptions'];$i++) {
    $option = $optionsarray[$i-1];
    $votes = $votesarray[$i-1];
    $number = $i;
    if($votedfor[$number]) {
        $votestar = "";
    } else {
        $votestar = "";
    }
    if($alreadyvoted || $showresults) {
        if (intval($votes) == "0"){
            $percent = "0";
        } else{
            $percent = ($votes / $poll['totvotes'] * 100);
        }

        $imagewidth = (round($percent)/3) * 5;
        $polloptions .=
        "<tr>
<td align='left' border='0' bgcolor='#202427'><font color='#FFFFFF' face='Verdana' size='1'>$option</td>
<td cellpadding='2' align='center' border='0' bgcolor='#202427'><font color='#FFFFFF' face='Verdana' size='1'>$percent%</td>
</tr>";
    } else {
        if($poll['multiple'] == "yes") {
            $polloptions .=
            "<tr>
<td border='0' width='5%'><input type='checkbox' name='option[$number]' value='yes'></td>
<td border='0' colspan='3' ><font color='#FFFFFF' face='Verdana' size='1'>$option</td>
</tr>";
        } else {
            $polloptions .=
            "<tr>
<td border='0' width='5%'><input type='radio' name='option' value='$number'></td>
<td border='0' colspan='3'><font color='#FFFFFF' face='Verdana' size='1'>$option</td>

        }
    }
}
if($poll['totvotes'])
{
    $totpercent = "100%";
}
else
{
    $totpercent = "0%";
}
if($alreadyvoted || $showresults) {
#$lang->total_votes = sprintf($lang->total_votes, $poll['numvotes']);
$pollbox = "<body bgcolor='#202427' topmargin='0' leftmargin='0' rightmargin='0' bottommargin='0'><table border='0' bgcolor='#202427' cellspacing='0' cellpadding='2'>
<tr>
<td colspan='2' border='0' align='center' bgcolor='#202427'><font color='#FFFFFF' face='Verdana' size='1'><strong>$poll[question]</strong><br /></td>

$polloptions

<td align='center'><font color='#FFFFFF' face='Verdana' size='1'><strong>$totpercent</strong></td>

<br />";
echo "$pollbox";
        } else {
$pollbox = 
"<form target='_parent' action='$url/polls.php' method='get'>
<input type='hidden' name='action' value='vote' />

Was willst du denn runden?

DaStaFlexX · 13.04.2007, 14:17

Ich möchte die Umfrage Ergebnisse runden.
Die sind extrem lang, 10 stellen !

Hier ein link dazu !

Wenn da z.B. stehen würde
66.33
33.33
wäre sehr passend !

bis gli...

Ersetze:

PHP-Code:
$percent = ($votes / $poll['totvotes'] * 100); 

durch:

PHP-Code:
$percent = ($votes / $poll['totvotes'] * 100);
$percent = round($percent, 2);
