我正在尝试解析HTML文件中输入的文本。我的代码应该调用一个PHP脚本，将输入的字段输出到服务器上的.txt文件中。我已经确保在网络服务器上给CHMOD 777访问.txt的权限，但在我单击"提交"后，没有任何内容被附加到该文件中。任何帮助都将不胜感激，为糟糕的语法和形式道歉。
HTML表单代码：
<form action="process.php" method="post">
<tr><td align="right">Name:</td><td><input name="auth_name" type="text" style="border: 1px dashed;"></td></tr>
<tr><td> </td></tr>
<tr>
<td align="right">E-mail Address:</td><td><input name="auth_mail" type="text" style="border: 1px dashed;"></td></tr>
<tr><td> </td></tr>
<tr>
PHP表单代码
<?php
if (isset ($_POST['submit'])) {
$user = $_POST['auth_name'];
$mail = $_POST['auth_mail'];
$border = "=================================='n";
$creds = 'creds.txt';
if (is_writeable($creds)) {
$creds_handle = fopen($creds, 'a') or die("Can't open file");
fwrite($creds_handle, $border);
fwrite($creds_handle, $user);
fwrite($creds_handle, "'n");
fwrite($creds_handle, $mail);
fwrite($creds_handle, "'n");
fwrite($creds_handle, $border);
}
fclose($creds_handle);
session_start();
$_SESSION['valid'] = '1';
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim(dirname($_SERVER['PHP_SELF']), '/''');
$extra = 'success.html';
header("Location: http://www.google.com");
}
else { die("Form submit failed"); }
?>
使用file_get_contents()和file_put_contents()函数。
示例：
$file = 'output.txt';
$buffer = 'my new line here';
if (file_exists($file)) {
$buffer = file_get_contents($file) . "'n" . $buffer;
}
$success = file_put_contents($file, $buffer);
在表单html代码和</form>标记中添加一个名为submit的输入。
<form action="process.php" method="post">
<tr><td align="right">Name:</td><td><input name="auth_name" type="text" style="border: 1px dashed;"></td></tr>
<tr><td> </td></tr>
<tr>
<td align="right">E-mail Address:</td><td><input name="auth_mail" type="text" style="border: 1px dashed;"></td></tr><tr><td> </td></tr>
<input type="submit" name="submit">
</form>
process.php
<?php
if (isset ($_POST['submit'])) {
$user = $_POST['auth_name'];
$mail = $_POST['auth_mail'];
$border = "=================================='n";
$creds = 'creds.txt';
//if (is_writeable($creds)) {
$creds_handle = fopen($creds, 'a') or die("Can't open file");
fwrite($creds_handle, $border);
fwrite($creds_handle, $user);
fwrite($creds_handle, "'n");
fwrite($creds_handle, $mail);
fwrite($creds_handle, "'n");
fwrite($creds_handle, $border);
//}
fclose($creds_handle);
session_start();
$_SESSION['valid'] = '1';
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim(dirname($_SERVER['PHP_SELF']), '/''');
$extra = 'success.html';
header("Location: ". $extra");
}
else { die("Form submit failed"); }
?>
