文本文件未更新
[英]Text file isn't updating
问题描述
I have this code: 
我有这个代码：
<?php
if(isset($_POST['submit'])){
$fi = "/home2/chippery/public_html/rtf/webR/top.txt";
$fih = fopen($fi, 'w');
$cont = $_POST["top"];
fwrite($fih,$cont);
fclose($fih);
$fi = "/home2/chippery/public_html/rtf/webR/bottom.txt";
$fih = fopen($fi, 'w');
$cont = $_POST["bottom"];
fwrite($fih,$cont);
fclose($fih);
$fi = "/home2/chippery/public_html/rtf/webR/nextTime.txt";
$fih = fopen($fi, 'w');
$cont = $_POST["time"];
fwrite($fih,$cont);
fclose($fih);
}
?>
<html>
<head>
<title>Chipperyman573</title>
<link rel="shortcut icon" href="/fav.ico" />
</head>
<body>
<form method="post" action="change.html">
Top: <input type="text" name="top" /><br>
Bottom: <input type="text" name="bottom" /><br>
Time (MS): <input type="text" name="time" /><br>
<input type="submit" value="Save" />
</form>
</body>
</html>
I have already made the text pages, and when I try to use this form the pages don't change. 我已经制作了文本页面，当我尝试使用此表单时，页面不会更改。 What am I doing wrong? 我究竟做错了什么？ I'm incredibly new to html/php so I'm sure it's something stupid. 我是非常新的html / php，所以我确定这是一个愚蠢的东西。

For writing content in file you should use fwrite() after opening the file in write mode. 要在文件中写入内容，在写入模式下打开文件后应使用fwrite() 。
And in your code few mistakes are there, updated code is here. 在您的代码中，几乎没有错误，更新的代码就在这里。 I have supposed your file name is myfile.php - 我原以为你的文件名是myfile.php -
<?php
if(isset($_POST['submit'])){
$fi = "top.txt";
$fih = fopen($fi, 'w');
$cont = $_POST["top"];
fwrite($fih,$cont);
fclose($fih);
$fi = "bottom.txt";
$fih = fopen($fi, 'w');
$cont = $_POST["bottom"];
fwrite($fih,$cont);
fclose($fih);
$fi = "nextTime.txt";
$fih = fopen($fi, 'w');
$cont = $_POST["time"];
fwrite($fih,$cont);
fclose($fih);
}
?>
<html>
<head>
<title>Chipperyman573</title>
<link rel="shortcut icon" href="/fav.ico" />
</head>
<body>
<form method="post" action="myfile.php">
Top: <input type="text" name="top" /><br>
Bottom: <input type="text" name="bottom" /><br>
Time (MS): <input type="text" name="time" /><br>
<input type="submit" value="Save" />
</form>
</body>
</html>

Also you can use the file_put_contents() function. 您也可以使用file_put_contents（）函数。
This function is identical to calling fopen(), fwrite() and fclose() successively to write data to a file.
<?php
if (isset($_POST['submit'])) {
$fi = "top.txt";
$cont = $_POST["top"];
file_put_contents($fi, $cont);
$fi = "bottom.txt";
$cont = $_POST["bottom"];
file_put_contents($fi, $cont);
$fi = "nextTime.txt";
$cont = $_POST["time"];
file_put_contents($fi, $cont);
}
?>

<?php
if(isset($_POST['submit'])){
$fi = "top.txt";
$fih = fopen($fi, 'w') <-- missing semi-colon
$cont = $_POST["top"] <-- missing semi-colon
fclose($fih);
$fi = "bottom.txt";
$fih = fopen($fi, 'w') <-- missing semi-colon
$cont = $_POST["bottom"];
fclose($fih);
$fi = "nextTime.txt";
$fih = fopen($fi, 'w') <-- missing semi-colon
$cont = $_POST["time"];
fclose($fih);
}
?>
And as Ritesh said, you aren't writing any data to your files. 正如Ritesh所说，你没有在文件中写入任何数据。 Just opening, and closing them. 打开，关闭它们。
