如何显示当前评级？

发布于 2024-10-15 00:07:34 字数 1461 浏览 9 评论 0原文

我想知道是否有人可以为我发布我需要对此代码进行的更改，以便在提交表单之前和之后在页面上显示当前的评级值，就像现在编写的那样。谢谢。

<?php echo '<html>
<head>
<title>Rating Tool Test</title>
</head>
<body>';
if ( (!isset($_POST['submit'])) ) { 
echo '<form action="'.$_SERVER['PHP_SELF'].'" method="post">
Your Rating: <select name="rate">'; 
for ($i = 1; $i <= 5; $i++) { 
echo "<option value=\"$i\">$i</option>"; } 

echo '</select><br /><input type="submit" value="Rate it!" name="submit"/>
   </form>';
} 
else  { 
$rate = isset ($_POST['rate']) ? $_POST['rate'] : 0;
$filename = "ratings";
$alreadyRated = false;
$totalRates = 0;
$totalPoints = 0;

$ip = getenv('REMOTE_ADDR');
$oldResults = file('results/'.$filename.'.txt');
foreach ($oldResults as $value) {
$oneRate = explode(':',$value);
if ($ip == $oneRate[0]) $alreadyRated = true;      
$totalRates++;
$totalPoints += $oneRate[1];
}
if ((!$alreadyRated) && ($rate > 0)){            
$f = fopen('results/'.$filename.".txt","a+");         
fwrite($f,$ip.':'.$rate."\n");
fclose($f);
$totalRates++;
$totalPoints+=$rate;
}
echo 'Total Average Rating:<br />'.substr(($totalPoints/$totalRates),0,3).' Out Of 5.<br />Total Votes: '.$totalRates.'<br />';
for ($i=0;$i<round(($totalPoints/$totalRates),0);$i++){
echo '<img src="style/star.gif" alt="star" />';
}
echo '</body>
</html>';       
} 
?>

I was wondering if someone could post for me the changes I need to make to this code to get the current rating values to display on the page before the form is submitted as well as after, as it is written now. Thanks.

<?php echo '<html>
<head>
<title>Rating Tool Test</title>
</head>
<body>';
if ( (!isset($_POST['submit'])) ) { 
echo '<form action="'.$_SERVER['PHP_SELF'].'" method="post">
Your Rating: <select name="rate">'; 
for ($i = 1; $i <= 5; $i++) { 
echo "<option value=\"$i\">$i</option>"; } 

echo '</select><br /><input type="submit" value="Rate it!" name="submit"/>
   </form>';
} 
else  { 
$rate = isset ($_POST['rate']) ? $_POST['rate'] : 0;
$filename = "ratings";
$alreadyRated = false;
$totalRates = 0;
$totalPoints = 0;

$ip = getenv('REMOTE_ADDR');
$oldResults = file('results/'.$filename.'.txt');
foreach ($oldResults as $value) {
$oneRate = explode(':',$value);
if ($ip == $oneRate[0]) $alreadyRated = true;      
$totalRates++;
$totalPoints += $oneRate[1];
}
if ((!$alreadyRated) && ($rate > 0)){            
$f = fopen('results/'.$filename.".txt","a+");         
fwrite($f,$ip.':'.$rate."\n");
fclose($f);
$totalRates++;
$totalPoints+=$rate;
}
echo 'Total Average Rating:<br />'.substr(($totalPoints/$totalRates),0,3).' Out Of 5.<br />Total Votes: '.$totalRates.'<br />';
for ($i=0;$i<round(($totalPoints/$totalRates),0);$i++){
echo '<img src="style/star.gif" alt="star" />';
}
echo '</body>
</html>';       
} 
?>
