从多个复选框中获取 POST 数据? [英] Get POST data from multiple checkboxes?
问题描述
我正在尝试使用 PHP 创建一个表单,但我似乎找不到关于我需要什么的教程,所以我想在这里问一下.
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?
I'm not sure however how to collect all checkbox values using POST method?
如果我使用
$service = $_POST['service'];
我只得到其他"返回
推荐答案
将字段命名为 service[]
而不是 service
,然后您就可以访问它作为数组.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("
", $_POST['service']);
遍历所有选中的复选框:
Loop through all selected checkboxes:
foreach ($_POST['service'] as $service) {
echo "You selected: $service <br>";
}
