Hey,

This problem should be easy to fix, I just wanted to see if anyone had a quick solution to my problem.

Here's the problem:

When a user rates, the script prints a mesage stating that the user has rated. When a user does not select a rating and still clicks on the submit button, he SHOULD get a message stating that he has not rated. This message is not displaying and I'm not sure why.

Here is the code I have so far:

Code:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<?php
///////////////results.txt updater///////////////////////
$rate = $_POST["rate"];
if ($rate) {
 if ($rate>0) {
 $File = "results.txt";
 $Handle = fopen($File, 'a');
 $Data = "$rate\n"; 
 fwrite($Handle, $Data);
 print "<small>Thanks for the rating!</small>"; 
 fclose($Handle); 
 }
 
 elseif ($rate==0) { //
 print "<small>Please select a rating.</small>"; //this is the problem area
 } //
}

//////////////////////Rating form//////////////////////////////////////////
echo "<form name=\"rating_form\" method=\"post\">";
echo "<select name=\"rate\">";
echo "<option value=\"0\">--rate--</option>";
echo  "<option value=\"100\">5</option>";
echo  "<option value=\"80\">4</option>";
echo   "<option value=\"60\">3</option>";
echo   "<option value=\"40\">2</option>";
echo   "<option value=\"20\">1</option>";
echo "</select>";
echo "<input name=\"submit\" type=\"submit\" value=\"Submit\">";
echo    "</form>";
echo "<table width=\"200\" border=\"1\" bordercolor=\"#666666\" cellpadding=\"0\" cellspacing=\"0\">";
echo "<tr>";
echo " <td style=\"$is_green_fix\" width=\"$result%\" height=\"15\"></td>";
echo  "<td width=\"$width_white\" style=\"$no_green_fix\"></td>";
echo "</tr>";
echo "</table>";
?>
</body>
</html>

Thanks for the help,
Moatist

Try this:

PHP Code:


			
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<?php
    /* results.txt updater */
    $rate = $_POST["rate"];
    if($rate > 0) {
        $File = "results.txt";
        $Handle = fopen($File, 'a');
        $Data = "$rate\n"; 
        fwrite($Handle, $Data);
        print "<small>Thanks for the rating!</small>"; 
        fclose($Handle); 
    }
     elseif ($rate == 0) {
        print "<small>Please select a rating.</small>";
    }

/* Rating form */
echo "<form name=\"rating_form\" method=\"post\">";
echo "<select name=\"rate\">";
echo "<option value=\"0\">--rate--</option>";
echo  "<option value=\"100\">5</option>";
echo  "<option value=\"80\">4</option>";
echo   "<option value=\"60\">3</option>";
echo   "<option value=\"40\">2</option>";
echo   "<option value=\"20\">1</option>";
echo "</select>";
echo "<input name=\"submit\" type=\"submit\" value=\"Submit\">";
echo    "</form>";
echo "<table width=\"200\" border=\"1\" bordercolor=\"#666666\" cellpadding=\"0\" cellspacing=\"0\">";
echo "<tr>";
echo " <td style=\"$is_green_fix\" width=\"$result%\" height=\"15\"></td>";
echo  "<td width=\"$width_white\" style=\"$no_green_fix\"></td>";
echo "</tr>";
echo "</table>";
?>
</body>

All right,

I fixed that problem but now I'm having bigger problems.

I figured out how to detect if someone has rated before by their IP address. This works fine. The problem is that I am not sure how to add the ratings up (I'll get the overall average later). The IPs/ratings are stored in a text file in the format ip:rating
69.157.243.112:60
69.157.243.112:80
69.157.243.112:20

Here's the code (I updated it):

PHP Code:


			
<html>
<head>
<title>Armor Films rating script</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<?php
///////////////IP check//////////////////////////////////
if (file_exists("results.txt")) {
$ip = getenv('REMOTE_ADDR');
$old_results = file('results.txt');
$already_rated = false;
      
      foreach ($old_results as $value_1) {
      $one_rate = explode(':',$value_1);
      
          if ($ip == $one_rate[0]) {
           $already_rated = true;     
              }
    }
}

///////////////results.txt updater///////////////////////
$rate = $_POST["rate"];
$users_ip = $_SERVER['REMOTE_ADDR'];

if ($rate && $already_rated != true) {

    if ($rate > 0) {
    $File = "results.txt";
    $Handle = fopen($File, 'a');
    $Data = "$users_ip:$rate\n"; 
    fwrite($Handle, $Data);  
    print "<small>Thanks for the rating!</small>";
    fclose($Handle); 
    }
    
}

elseif ($rate && $already_rated = true) {
    print "<small>You have already rated.</small>";
    }


////////////value handler////////////////////////////////
$value_file = fopen("results.txt", "r");

while(!feof($value_file)) {
    $line = fgets($value_file);
    $rating_values = substr($line, -3);
        print $rating_values;
        }
                

fclose($value_file);

echo $total;
//////////////////////Rating form//////////////////////////////////////////
echo "<form name=\"rating_form\" method=\"post\">";
echo    "<select name=\"rate\">";
echo    "<option value=\"0\">--rate--</option>";
echo     "<option value=\"100\">5</option>";
echo     "<option value=\"80\">4</option>";
echo      "<option value=\"60\">3</option>";
echo      "<option value=\"40\">2</option>";
echo      "<option value=\"20\">1</option>";
echo    "</select>";
echo    "<input name=\"submit\" type=\"submit\" value=\"Submit\">";
echo    "</form>";

echo "<table width=\"200\" border=\"1\" bordercolor=\"#666666\" cellpadding=\"0\" cellspacing=\"0\">";
echo    "<tr>";
echo    "    <td style=\"$is_green_fix\" width=\"$result%\" height=\"15\"></td>";
echo        "<td width=\"$width_white\" style=\"$no_green_fix\"></td>";
echo    "</tr>";
echo "</table>";
?>
</body>
</html>
