How to validate if checkbox is checked in laravel?
提问by lilly
I have a checkbox in my view
我的视图中有一个复选框
<input type="checkbox" id="test5">
and I want to validate in my controller if the checkbox is checked
如果复选框被选中，我想在我的控制器中进行验证
if (Input::get('test5') === true) {
//insert 1
} else {
//insert 0
}

First, a checkbox (any kind of input must) must have a name and a value.
首先，复选框（任何类型的输入都必须）必须具有名称和值。
<input type="checkbox" name="mycheckbox" value="1" id="test6">
Then on your controller you do:
然后在您的控制器上执行以下操作：
Request::get('mycheckbox')
This will output the value of your checkbox if it's checked, or nullif not (browser don't send anything)
如果选中或未选中，这将输出复选框的值null（浏览器不发送任何内容）
if (Request::get('mycheckbox') {
// Do anything here
}
Notethat the input idattribute don't care. The important here is the input nameattribute.
请注意，输入id属性并不关心。这里重要的是输入name属性。

you can validate everything normally and then when you pass the request to an array with $data = $request->all();you can check if the checkbox is checked by just checking if the 'mycheckbox' space is empty like:
您可以正常验证所有内容，然后当您将请求传递给数组时，$data = $request->all();您可以通过检查“mycheckbox”空间是否为空来检查是否选中了复选框：
$dataValidate = $request->validate([
'something' => 'required|numeric|min:3|max:99',
'something' => 'required|numeric',
'something' => 'required|numeric',
'something' => 'required|alpha_dash',
'something' => 'required|email',
'something' => ['required', new SomethingRule],
'something' => 'required|starts_with:0,+',
'something' => 'nullable|numeric',
]);
$data = $request->all();
if (empty($data['mycheckbox'])) {
//something if the checkbox is not checked
}else{
//something if the checkbox is checked
}
This is something that I do from time to time I dunno if it is the best practice but it does the job and does not make anything worse
这是我不时做的事情，我不知道这是否是最佳实践，但它可以完成工作并且不会使任何事情变得更糟
