计数多少复选框被检查php / html [英] counting how many checkbox are checked php/html

问题描述

您好，我是php的新，我想知道如何计数一旦我点击提交检查了多少'复选框。
例如：

Hi I am new with php and I was wondering how am i able to count how many 'checkbox' are checked once I click on submit. For example:

<input type = "checkbox" value = "box" name = "checkbox1"/>
<input type = "checkbox" value = "box" name = "checkbox2"/>
<input type = "checkbox" value = "box" name = "checkbox3"/>

推荐答案

Give the checkboxes names as array like

<input type = "checkbox" value = "box" name = "checkbox[]"/>

在提交之后，尝试类似

$checked_arr = $_POST['checkbox'];
$count = count($checked_arr);
echo "There are ".$count." checkboxe(s) are checked";

注意：根据您使用表单提交的方式。 $ _ GET 或 $ _ POST 您需要使用 $ _ POST [' GET 方法的 POST 方法和 $ _ GET ['checkbox'] 方法。

Note : And based on the method that your form submit using...whether it is $_GET or $_POST you need to use $_POST['checkbox'] for POST method and $_GET['checkbox'] for the GET method.
