php post 到变量，然后附加到 txt [英] php post to variable and then append to txt

问题描述

我遇到了这个问题，我无法完成这个简单的脚本.基本上，我想从表单中获取一个帖子，将其分配给一个变量，然后将该变量附加到预先存在的 example.txt 文件中.我为缺乏例子道歉，我在和我的姻亲出去吃饭后切换到我的手机.任何人都可以发布一个简单的示例并允许我建立该基础吗?提前致谢

I'm having this problem where I can't manage to accomplish this simple script. Basically, I want to take a post from a form, assign it to a variable, and then append the variable to a preexisting example.txt file. I apologize for the lack of examples, I switched to my phone after I went out to dinner with my inlaws. Could anyone post a simple example andd allow me to build off of that foundation? thanks in advance

推荐答案

以下内容将为您提供一个开始的基础.

The following should give you a foundation to start.

<?php

// Check to see if the form was submitted

if(isset($_POST['action']) && $_POST['action'] == 'add'){

    $file = 'example.txt';

    // Open the file to get existing content
    $current = file_get_contents($file);

    // Append a new person to the file
    $current .= $_POST['test'];

    // Write the contents back to the file
    file_put_contents($file, $current);
}

?>

<form method="POST">

    <!-- This becomes PHP variable $_POST['test'] -->
    <input type="text" name="test" /> 

    <input type="hidden" name="action" value="add" />
    <input type="submit" value="Add"/>
</form>
