如何将文本插入到 html <textarea>提交错误后? [英] How to keep text inserted in a html <textarea> after a wrong submission?

问题描述

假设我有一个这样的表单:

Suppose I have a form like this:

<form action="page.php" method="post">

    Section1: <input name="section1" type="text"></br>
    Section2: <input name="section2" type="text"></br>

    Text:</br>
    <textarea name="post_text" cols="100" rows="20"></textarea>

    <input name="submit" type="submit" value="Submit">

</form>

通常，如果我想保存插入到表单字段中的内容，我会使用以下语句:

Usually if I wish to save content inserted in a field of the form I would use this statement:

Section1: <input name="section1" type="text" vale="value="<?php echo $_POST['section1']; ?>""></br>

这样如果我提交错误(错误控制代码不贴)，插入的值会被保留，不需要重新插入.

This way if I make a mistake in submission (error control code is not posted) the values inserted will be kept, and there is no need to reinsert them.

但是在 textarea 标签中使用它不会产生预期的结果.

However using it in the textarea tag it will not produce the desired result.

关于如何做的任何想法?

Any ideas on how to do?

提前致谢！
