无法通过post方法获取textarea的值
问题描述：
这是一个非常简单的表格，如下面的代码所示：
It is a very simple form as in the code below:
<form method="POST" action="news.php?nid=2">
<textarea id="txtcomment" style="width:100%; height: 70px;" maxlength="300"></textarea><br /><br />
<input type="submit" class="button" style="float: right; cursor:pointer;" value="Comment">
</form>
但在news.php中我无法获得txtcomment的价值
but in the news.php i cannot get the value of "txtcomment"
echo $_POST['txtcomment'];
它什么也不返回......
it returns nothing...
答
这是因为你需要命名textarea：
It is because you need to name the textarea:
<textarea name="txtcomment"></textarea>
id 参数没有任何内容如何使用表单（除了标签 s，但这在这里并不重要）。
The id parameter does not have anything to do with how forms work (with the exception of labels, but that is not important here).
