文本文件的简单PHP编辑器 [英] Simple PHP editor of text files

问题描述

我已经为客户开发了一个站点，他希望能够在后端类型的解决方案中编辑主页的一小部分.因此，作为解决方案，我想添加一个非常基本的编辑器(domain.com/backend/editor.php)，当您访问它时，它将具有一个带有代码和保存按钮的文本字段.它将要编辑的代码将设置为TXT文件.

I have developed a site for a client and he wants to be able to edit a small part of the main page in a backend type of solution. So as a solution, I want to add a very basic editor (domain.com/backend/editor.php) that when you visit it, it will have a textfield with the code and a save button. The code that it will edit will be set to a TXT file.

我认为这样的事情在PHP中很容易编写，但是google这次并没有为我提供帮助，因此我希望这里有人会为我指明正确的方向.请注意，我没有PHP编程的经验，只有HTML和基本的javascript，所以请在提供的任何答复中都做到周密.

I would presume that such thing would be easy to code in PHP but google didn't assist me this time so I am hoping that there might be someone here that would point me to the right direction. Note that I have no experience in PHP programming, only HTML and basic javascript so please be thorough in any reply that you provide.

推荐答案

您创建HTML表单来编辑文本文件的内容.如果提交了，则更新文本文件(并再次重定向到表单，以防止出现F5/刷新警告):

You create a HTML form to edit the text-file's content. In case it get's submitted, you update the text-file (and redirect to the form again to prevent F5/Refresh warnings):

<?php

// configuration
$url = 'http://example.com/backend/editor.php';
$file = '/path/to/txt/file';

// check if form has been submitted
if (isset($_POST['text']))
{
    // save the text contents
    file_put_contents($file, $_POST['text']);

    // redirect to form again
    header(sprintf('Location: %s', $url));
    printf('<a href="%s">Moved</a>.', htmlspecialchars($url));
    exit();
}

// read the textfile
$text = file_get_contents($file);

?>
<!-- HTML form -->
<form action="" method="post">
<textarea name="text"><?php echo htmlspecialchars($text) ?></textarea>
<input type="submit" />
<input type="reset" />
</form>
