使用PHP将信息从HTML表单发送到文本文件 - Sending info from HTML form to a a text file using PHP

我想知道如何使用PHP将信息从HTML表单发送到文本文件。我当前的代码没有向文本文件添加任何内容。HTML和PHP文件如下。希望有人能帮助我，如果需要更多信息，请告诉我，我会在评论中为你提供信息。

HTML

<form action="results.php" method="post">
    <table border="1">
        <tr>
            <th colspan="7">Survey (CSC443)</th>
        </tr>
        <tr>
            <td rowspan="2">#</td>
            <td rowspan="2">Question</td>
            <td>Strongly</td>
            <td>Somewhat</td>
            <td></td>
            <td>Somewhat</td>
            <td>Strongly</td>
        </tr>
        <tr align="center">
                <td colspan="2">Disagree</td>
                <td>Neutral</td>
                <td colspan="2">Agree</td>
        </tr>
        <tr>
            <td>1</td>
            <td>This course helped me develop problem-solving skills.</td>
            <td align="center"><input type="radio" name="q1" value="1"></td>

            <td align="center"><input type="radio" name="q1" value="5"></td>
        </tr>
        <tr>
            <td>2</td>
            <td>This course was very challenging.</td>

            <td align="center"><input type="radio" name="q2" value="5"></td>
        </tr>
        <tr>
            <td>3</td>
            <td>My programming ability increased after aking this course.</td>
            <td align="center"><input type="radio" name="q3" value="1"></td>
            <td align="center"><input type="radio" name="q3" value="2"></td>

            <td align="center"><input type="radio" name="q3" value="5"></td>
        </tr>
        <tr>
            <td>4</td>
            <td>I will list 'Javascript' on my resume.</td>
            <td align="center"><input type="radio" name="q4" value="1"></td>
            <td align="center"><input type="radio" name="q4" value="2"></td>
            <td align="center"><input type="radio" name="q4" value="3" checked></td>
            <td align="center"><input type="radio" name="q4" value="4"></td>
            <td align="center"><input type="radio" name="q4" value="5"></td>
        </tr>
        <tr align="center">
            <td colspan="2"></td>
            <td>1</td>
            <td>2</td>
            <td>3</td>
            <td>4</td>
            <td>5</td>
        </tr>
        <tr>
            <td colspan="7" rowspan="2" align="center"><input type="submit" value="Submit"> <input type="reset" value="Reset"></td>
        </tr>
    </table>
</form>

PHP

if(isset($_POST['q1'] && isset($_POST['q2'] && isset($_POST['q3'] && isset($_POST['q4'])
 {
  $q1 = $_POST['q1'];
  $q2 = $_POST['q2'];
  $q3 = $_POST['q3'];
  $q4 = $_POST['q4'];
  $text = $q1 . "," . $q2 . "," . $q3 . "," . $q4 . "'n";
  $ret = file_put_contents('/results.txt', $text, FILE_APPEND | LOCK_EX);
  if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }
}
else {
   die('no post data to process');
}

问题出在这一行，其中缺少几个)的右括号。

if(isset($_POST['q1'] && isset($_POST['q2'] && isset($_POST['q3'] && isset($_POST['q4'])
                 ----)                 ----)                 ----)                  ----)

替换为：

if(isset($_POST['q1']) && isset($_POST['q2']) && isset($_POST['q3']) && isset($_POST['q4']))

此外，可能还有其他问题。我（成功）使用对此进行了测试

$ret = file_put_contents('results.txt', $text, FILE_APPEND | LOCK_EX);

results.txt 前面没有/

注意：使用相对路径而不是绝对路径

如果需要设置文件，则将文件权限设置为0644比0777更安全。

重写：（在与文本文件相同的文件夹中运行代码）

如果文件位于执行文件夹的下一级，则根据执行代码和文本文件的位置使用'../results.txt'。

<?php
if(isset($_POST['q1']) && isset($_POST['q2']) && isset($_POST['q3']) && isset($_POST['q4']))
 {
  $q1 = $_POST['q1'];
  $q2 = $_POST['q2'];
  $q3 = $_POST['q3'];
  $q4 = $_POST['q4'];
  $text = $q1 . "," . $q2 . "," . $q3 . "," . $q4 . "'n";
  $ret = file_put_contents('results.txt', $text, FILE_APPEND | LOCK_EX);
  if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }
}
else {
   die('no post data to process');
}
?>

在你的result.php中有一些小错误，这里是修复的php代码

 <?php
 if(isset($_POST['q1']) && isset($_POST['q2']) && isset($_POST['q3']) && isset($_POST['q4']))
  {
   $q1 = $_POST['q1'];
   $q2 = $_POST['q2'];
   $q3 = $_POST['q3'];
   $q4 = $_POST['q4'];
   $text = $q1 . "," . $q2 . "," . $q3 . "," . $q4 . "'n";
   $ret = file_put_contents('results.txt', $text, FILE_APPEND | LOCK_EX);
   if($ret === false) {
    die('There was an error writing this file');
     }
     else {
    echo "$ret bytes written to file";
     }
 }
 else {
    die('no post data to process');
 }
 ?>
