问题描述
我想验证是否在php中选中了我的复选框,如果是,我想回显 Hello word。
这是我的html代码:
I want to verify if my checkbox is checked in php and if it is, i want to echo "Hello word". Here is my html code :
<form class="checkclass">
<input type="checkbox" name="checkbox1"> 4K </input>
</form>
php:
<?php
if (isset($_POST['checkbox1'])) {
echo "Hello world!";
}
?>
但是它不起作用,我真的不知道该如何解决。
有人可以帮我吗?
But it doesn't work and i really don't know how to fix this. Can someone please help me ?
推荐答案
isset($ _ GET ['checkbox1'] ))
不起作用,因为它正在检查URL查询字符串。不是表单提交。使用$ _POST代替$ _GET。就像这样:
isset($_GET['checkbox1']))
does not work because it is checking a URL query string. NOT a form submission. Use $_POST instead of $_GET. So it would be like this:
if (isset($_POST['checkbox1'])) {
// Go ahead and do stuff because it is checked
}
