使用 PHP 表单帖子检查复选框? [英] Checkbox checked with PHP form post?

问题描述

如何选中复选框?

我已经尝试过 1、On 和 Yes.那行不通.单独放置工作的检查"是可行的，但是在选中复选框的表单帖子后如何检查 PHP?

I've tried 1, On, and Yes. That doesn't work. Putting the worked "checked" alone works, but then how do I check with PHP after a form post of the checkbox is checked?

<input type="checkbox" class="inputcheckbox" id="newmsg" name=chk[newmsg2] value="1" />

推荐答案

复选框只有被选中才会成功.

A checkbox will only be a successful control if it is checked.

不成功的控件不会作为数据提交.

Controls that are not successful are not submitted as data.

因此，您可以通过查看复选框的值是否已提交来判断其是否被选中.

Therefore, you can tell if a checkbox is checked by seeing if its value has been submitted.

例如

if ($_POST['chk']['newmsg2'] == 1) {
