How to add validation for checkbox in laravel 5? - laravel

Question

I have an array of checkboxes including a hidden checkbox so i can send a value 0 if a checkbox is not checked.
#foreach($records as $record)
<tr>
<td>{{ $record->name }}</td>
<td>{{ $record->id }}</td>
<td>
<input type="hidden" name="record_checkbox[{{ $loop->index }}]" value="0" />
<input type="checkbox" class="form-control name="record_checkbox[{{ $loop->index }}]" value="1" />
</td>
</tr>
#endforeach
I want to validate that only 0 or 1 is sent when a user submits the form.
In my controller I have tried using this:
$this->validate($request, [
'record_checkbox[]' => 'integer|boolean|min:0|max:1',
]);
But when I use browser developer tools and manually update the value field of checkbox to 100, it still accepts it and stores it in database.
So how can I only allow 0 or 1 by proper validation?

Answer 1

Remove brackets if you want to validate all array inputs:
$this->validate($request, [
'record_checkbox' => 'in:0,1',
]);
Edit
Create custom rule: inside app/Providers/AppServiceProvider.php under boot method add the following:
use Illuminate\Support\Facades\Validator;
...
public function boot() {
Validator::extend('validate_checkboxes', function ($attribute, $values, $parameters, $validator) {
foreach( $values as $value ) {
if (!in_array($value, [0, 1])) {
return false;
}
return true;
}
});
}
And then in your controller:
$this->validate($request, [
'record_checkbox' => 'validate_checkboxes',
]);

I've been trying to find a good answer to this for about a month and I think I finally got a good solution, so I'll share it. I have something similar, where I have like 3 or 4 checkbox fields that determine tiny int switches in my database. The way I did this is to add this line in app/Providers/AppServiceProvider.php:
Validator::extendImplicit('checkbox', function($attribute, $value, $parameters, $validator)
{
$data = $validator->getData();
$data[$attribute] = ($value == "1" || strtolower($value) == "true" || strtolower($value) == "on")? "1": "0";
$validator->setData($data);
return true;
});
Explanation:
Validator::extendImplicit
This makes sure that, regardless of whether the attribute is in the request object or not (and if it was unchecked it will not be) it will still run this rule anyways.
$data = $validator->getData();
$data[$attribute] = ($value == "1" || strtolower($value) == "true" || strtolower($value) == "on")? "1": "0";
$validator->setData($data);
Once we enter this function we will get the data array and add the entry for the checkbox as either a 0 or a 1 (note I'm not changing the request object, although you could do that too with something like request->merge() or request()->add()), it then sets the new data array. So in your controller you would simply:
$data = $request->validate(['record_checkbox' => 'checkbox']);
And your data array will contain the field 'record_checkbox' set to either 0 or 1. You can now use this array to fill() your model.
Hope this helps!

Let try:
use Illuminate\Validation\Rule;
$request->validate([
'record_checkbox[]' => [
'required|in_array:[0, 1]'
]
]);
