Getting input from text area and echoing it out
提问by RSM
I have written some basic code so that a text area is displayed, and when the user inputs the text, clicks submit and it shows on the page in the method=''.
我已经编写了一些基本代码，以便显示一个文本区域，当用户输入文本时，单击提交并在页面上的 method='' 中显示。
The code i have for the form is :
我的表格代码是：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>Fun Translator</h1>
<form method="post" action="query.php">
<textarea name="txtarea">
</textarea>
<input type="submit" />
</form>
The code on the page query.php is:
页面 query.php 上的代码是：
<html>
<body>
<?php
echo $_POST["txtarea"];
?>
</body>
</html>
By looking at google, other questions and such, this should work, but doesnt!
通过查看谷歌，其他问题等，这应该有效，但没有！

Thanks to Marc Audet, I put in phpinfo and all that came up in a big table as it does, I took it out and it started working. Any explanations?
多亏了 Marc Audet，我把 phpinfo 和所有出现在一个大表中的东西都放进去了，我把它拿出来，它开始工作了。有什么解释吗？

The textarea is not link to your form, you should add form="" in textarea like this:
textarea 不是链接到您的表单，您应该在 textarea 中添加 form="" ，如下所示：
<form method="post" action="query.php" name="myform">
<textarea name="txtarea" form="myform">

use
echo htmlspecialchars($_POST['name']);to get value.
使用
echo htmlspecialchars($_POST['name']);中获取价值。

Best guess: Your server doesn't support PHP.
最佳猜测：您的服务器不支持 PHP。
Check the source code as delivered to the browser. If the <?phpbit shows up, then the server hasn't run the page through a PHP engine.
检查交付给浏览器的源代码。如果该<?php位出现，则服务器尚未通过 PHP 引擎运行该页面。

As far as I know you should be doing textarea in the quotes not txtarea, I am not really sure though, it might be beneficial to use an ID instead.
据我所知，您应该在引号中而不是 txtarea 中使用 textarea，但我不确定，但使用 ID 可能会有所帮助。
