从多个复选框获取POST数据? [英] Get POST data from multiple checkboxes?

问题描述

我正在尝试使用PHP创建表单，但似乎找不到关于我需要的教程，因此我想在这里询问.

Im trying to create a form using PHP and I cant seem to find a tutorial on what I need so thought Id ask on here.

我的页面上有多个复选框选项...

I have a multiple checkbox option on my page...

 <li>
    <label>What service are you enquiring about?</label>
    <input type="checkbox" value="Static guarding" name="service">Static guarding<br>
    <input type="checkbox" value="Mobile Patrols" name="service">Mobile Patrols<br>
    <input type="checkbox" value="Alarm response escorting" name="service">Alarm response escorting<br>
    <input type="checkbox" value="Alarm response/ Keyholding" name="service">Alarm response/ Keyholding<br>
    <input type="checkbox" value="Other" name="service">Other<input type="hidden" value="Other" name="service"></span>
  </li>

但是我不确定如何使用POST方法收集所有复选框值吗?

I'm not sure however how to collect all checkbox values using POST method?

如果我使用

$service = $_POST['service'];

我只得到'other'返回

I only get 'other' returned

推荐答案

命名诸如service[]之类的字段，而不是service，则可以将其作为数组访问.之后，您可以将常规函数应用于数组:

Name the fields like service[] instead of service, then you'll be able to access it as array. After that, you can apply regular functions to arrays:

• 检查是否选择了某个值:

• Check if a certain value was selected:

 if (in_array("Other", $_POST['service'])) { /* Other was selected */}

获取包含所有选定选项的单个换行符分隔的字符串:

Get a single newline-separated string with all selected options:

 echo implode("\n", $_POST['service']);

浏览所有选中的复选框:

Loop through all selected checkboxes:

 foreach ($_POST['service'] as $service) {
     echo "You selected: $service <br>";
 }
