问题描述

我有两个问题:-
1.我需要能够设置一个textarea的值
2.然后我需要再次获取文本区域的值以进行更新.我看到文本区域没有值"标签或其他东西..所以我不知道如何通过 PHP 做到这一点.我试过类似

I have two issues:-
1. I need to be able to set the value of a textarea
2. I need to then get the value of the text area again for updating. I see that text area does not have a 'value' tag or something.. so I am not sure how to do this via PHP. I tried something like

print("<textarea cols='15' rows='2' name='textdesc'>$info_desc</textarea>");

设置它.但是没有运气，然后我在检索时会遇到同样的问题.

to set it. But no luck and then i will have the same problem when retrieving.

推荐答案

在 HTML 中设置值...

To set the value in HTML...

<textarea cols="15" rows="2" name="textdesc"><?php echo htmlspecialchars(
    $info_desc, ENT_QUOTES, 'UTF-8') ?></textarea>

要检索它(假设您的表单发出 POST 请求)...

To retrieve it (assuming your form issues a POST request)...

if (isset($_POST['textdesc'])) {
    $textdesc = $_POST['textdesc'];
}
