Question

到目前为止我所做的是使用eclipse构建了一个基于java的web服务器。我可以访问我创建的index.html页面。现在我正在尝试创建一个联系表单，用户可以在其中输入信息并提交写入和修改文本文件，清除表单并显示用户在页面底部提交的数据任何建议。

注意：根据请求，我编辑了这篇文章以包含代码。

<?php
$saving = $_REQUEST['saving'];
if ($saving == 1){ 
$data = $_POST['data'];
$file = "data.txt"; 

$fp = fopen($file, "w") or die("Couldn't open $file for writing!");
fwrite($fp, $data) or die("Couldn't write values to file!"); 

fclose($fp); 
echo "Saved to $file successfully!";

}
?>

<form name="form1" method="post" action="data.php?saving=1">
<textarea name="data" cols="100" rows="10">
Name: 
Address: 
Email: 
Phone: 
---------------------------------------------
</textarea>
<br>
<input type="submit" value="Save">
</form>
<p>

<a href="data.txt"><b>VIEW<b></a>

我也更新了你的一些HTML，所以请检查一下。你正在做的是在这段代码中一次又一次地重写整个文件，删除bug。

<?php
if (isset($_POST['submit'])) {

    $writeComment = implode('', file('test.txt')) . '[!@X#$]'. $_POST['data'];
    $myfile = fopen("test.txt", "w") or die("Unable to open file!");

    fwrite($myfile, rtrim($writeComment, '[!@X#$]'));
    fclose($myfile);
}

$fileContent = implode('', file('test.txt'));
$comments = explode('[!@X#$]', rtrim($fileContent, '[!@X#$]'));

?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="UTF-8" />
    <title>Submit Data</title>
</head>
<body>

    <form id="input" action="" method="post">
        Comment: <textarea name="data" cols="100" rows="10">
            Name: 
            Address: 
            Email: 
            Phone: 
            ---------------------------------------------
        </textarea>
        <input type="submit" name="submit" value="Submit">
    </form>
    <table>
        <?php foreach ($comments as $i => $comment) { ?>
        <tr>
            <td>
                Comment(<?php echo ($i + 1)?>):
            </td>
            <td>
                <?php echo $comment;?>
            </tr>
        </td>
        <?php }?>
    </table>
    <a href="test.txt">View Core File</a>
</body>
</html>
