How to store multiple checkbox values to database in Laravel? - php

Question

I need to store checkbox values into the database. I have tried so many examples, but still am not able to do that, Here I will give you my code and give me the solution for this.
My Blade File
<div class="form-group row">
<label for="hobbies" class="col-md-4 col-form-label text-md-right">Hobbies</label>
<div class="col-md-6">
<input type="checkbox" name="hobbies[]" value="Readbooks"/> Readbooks
<input type="checkbox" name="hobbies[]" value="Games"/> Games
<input type="checkbox" name="hobbies[]" value="Music"/> Music
#if ($errors->has('hobbies'))
<span class="text-danger">{{ $errors->first('hobbies') }}</span>
#endif
</div>
</div>
My Controller File
public function postRegistration(Request $request)
{
$data = $request->all();
$check = $this->create($data);
return redirect("login")->withSuccess('Great! please login.');
}
public function create(array $data)
{
return User::create([
'hobbies' => $data->implode([',', (array) $data->get('hobbies')]),
]);
}
Error:Call to a member function implode() on array

Answer 1

This is not how you use the implode method. And like the error says; you try to call a method on an array, because $data is an array and not an object.
And last, $data->get('hobbies') will also cause you problems, because the get() helper is not working on an array.
This is what you need:
return User::create([
'hobbies' => implode(',', (array) $data['hobbies']),
]);

Answer 2

When you have inputs like:
<input type="checkbox" name="hobbies[]" value="Readbooks"/> Readbooks
<input type="checkbox" name="hobbies[]" value="Games"/> Games
<input type="checkbox" name="hobbies[]" value="Music"/> Music
The POST data received by the server includes hobbies as an array. You can confirm this by inspecting the received request in your controller:
public function postRegistration(Request $request) {
dd($request);
}
Since $request->hobbies is already an array, there is no need to cast it with (array).
In the code you've shown, you are trying to implode() your hobbies. implode() generates a string, so if the hobbies field you are trying to populate in the database is a string, you simply need to implode that received array of hobbies:
// Will generate a string like: "Readbooks,Music"
implode(',', $request->hobbies);
Putting it into your code:
public function create($data) {
return User::create(['hobbies' => implode(',', $data->hobbies)];
}
