我正在尝试制作一个PHP页面，该页面将向用户询问三件事。一封电子邮件、一个名字和一个姓氏。我希望将这些数据存储并保存在我的计算机上。现在我正在本地运行XAMPP。
当我输入表单标签时，它会重定向。我想保存数据。
假设用户（我自己）在一封"johnmayer@gmail.com"点击sumbit按钮后，我如何将这些信息保存在PHP页面上？
包含HTML表单的数据输入页面应该如下所示：
<form action="save-data.php" method="POST">
<input name="firstname" type="text" />
<input name="lastname" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
现在在名为save-data.PHP的PHP文件中：
<?php
if(isset($_POST['firstname']) && isset($_POST['lastname'])) {
$data = $_POST['firstname'] . '-' . $_POST['lastname'] . "'n";
$ret = file_put_contents('/tmp/mydata.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "$ret bytes written to file";
}
}
else {
die('no post data to process');
}
请注意，"tmp/mydata.txt"是要写入数据的文件的路径。并且它必须具有适当的写入权限。
HTML:
<form action="mailer.php?savedata=1" method="post">
First Name: <input type="text" name="first_name"><br>
LastName: <input type="text" name="last_name"><br>
Your Email: <input type="text" name="email"><br>
<input type="submit" name="submit" value="Submit">
</form>
PHP:
<?php
$savedata = $_REQUEST['savedata'];
if ($savedata == 1){
$data = $_POST['first_name'];
$data .= $_POST['last_name'];
$data .= $_POST['email'];
$file = "YOURDATAFILE.txt";
$fp = fopen($file, "a") or die("Couldn't open $file for writing!");
fwrite($fp, $data) or die("Couldn't write values to file!");
fclose($fp);
echo "Your Form has been Submitted!";
}
?>
非常感谢大家。这是我自己写了一些代码后发现的。
