Problem with storing checkbox values in database - php

Question

I am trying to store my checkbox values in database. I have these three tables.
fields
id name
1 gender
2 looking_for
field_values (here field_id references id on fields table)
id field_id value label
1 1 1 Men
2 1 2 Women
3 2 3 Relationship
4 2 4 Friendship
5 2 5 Marriage
user_interests (here field_id references field_id on field_values table and value_id references value on field_values table)
user_id field_id value_id
1 1 2
1 2 4
1 2 5
gender in blade uses option values and looking_for uses checkbox values. I made one function that is trying to update both of them. I use two foreaches in my function and I am able to successfully update gender option, but I am unable to update looking_for option. When I click submit button nothing happens, also when I dump anything inside that foreach that is supposed to update checkboxes it doesn't dump. Any help is greatly appreciated. Here is my code.
web.php
Route::patch('profile/interests', 'UserProfileController#updateInterestsData')->name('profile.update.interests.data');
UserProfileController.php
public function updateInterestsData(UpdateInterestsDataRequest $request)
{
$user = User::with('userProfile')->where('id', Auth::user()->id)->firstOrFail();
$request->validated();
$userId = $request->input('user_id') ? $request->input('user_id') : Auth::user()->id;
$data = $request->all();
$options = [
'gender' => 1,
'looking_for' => 2
];
foreach ($options as $fieldName => $fieldId) {
if (! empty($data[$fieldName])) {
DB::table('user_interests')
->where('user_id', $userId)
->where('field_id', $fieldId)
->delete();
if (is_array($data[$fieldName])) { // CHECKBOX FIELDS AND HERE IT DOESN'T WORK!!!
//dd('DIE!!!!!!') IT DOESN'T ENTER HERE!!!
foreach ($data[$fieldName] as $key => $value) {
DB::table('user_interests')->insert([
'user_id' => $userId,
'field_id' => $fieldId,
'value_id' => $value
]);
}
} else { // SELECT FIELDS!!!
DB::table('user_interests')->insert([
'user_id' => $userId,
'field_id' => $fieldId,
'value_id' => $data[$fieldName]
]);
}
}
}
$user->userProfile->update(
[
'age_from_preference' => $request->age_from_preference,
'age_to_preference' => $request->age_to_preference,
'updated_at' => Carbon::now()
]
);
$request->user()->save();
return redirect()->route('profile.show', [$user->username]);
}

If I understand your problem correctly, to deal with multiple checkboxes on PHP you need to add [] to its name property. That way, PHP knows it should interpret theses values as an array.
Also, your input name is not matching with $data[$fieldName].
Do it like this:
#isset($options)
<div class="form-group flex mt-5">
#foreach($options as $name => $fieldData)
#if ($name == 'looking_for')
#foreach ($options[$name]['data'] as $value=>$label)
<div class="interestedIn">
<input type="checkbox" name="{{ $name }}[]" value="{{ $value }}" {{ isset($data[$fieldData['label']['id']]) ? (in_array($value, $data[$fieldData['label']['id']]) ? 'checked' : null) : '' }} id="{{$name}}-{{ $value }}">
<label for="{{$name}}-{{ $value }}">{{ $label }}</label>
</div>
#endforeach
#endif
#endforeach
</div>
#endisset
