简单的html/php表单可在同一页面上输出 [英] Simple html/php form to output on the same page
问题描述
基本上，我想要的只是让用户进入该网站，键入他们的消息和名称，结果应该显示在同一页面上，并且当另一个用户再次进入时，前一个用户的结果应该在那里出现的所有内容都应添加到列表中.
Basically all I want is for users to come into the site, type in their message and name, and the results should be displayed in the same page and when another user comes in again, the results from previous user should be there and anything that comes up should just be added to the list.
目前我有:
<form id="form1" name="form1" method="post" action="">
<label>Please type in a message
<input type="text" name="msg" id="msg" />
</label>
<label>and your name
<input type="text" name="pin" id="name" />
</label>
<p>
<label>Submit
<input type="submit" name="submit" id="submit" value="Submit" />
</label>
</p>
</form>
<?php
$msg = $_POST[msg];
$name = $_POST[name];
?>
<br />
<?php echo "$msg"?>
<?php echo "$name"?>
但是当输入另一条记录时，上一条将丢失...
but when another record is type in, the previous one is lost...
预先感谢
推荐答案
这应该做您想要的.它从posts.txt加载以前的帖子，添加当前帖子，显示并保存.您需要确保posts.txt存在并且具有正确的权限.
This should do what you want. It loads previous posts from posts.txt, adds the current one, displays the posts and saves it. You'll need to make sure posts.txt exists and has correct permissions.
