How to handle multiple checkboxes in PHP for storing and processing selections?
I am working on a web application where I have a form with multiple checkboxes, and I'm struggling with how to handle and process the selected checkbox values. I am using PHP and Laravel framework for the backend.
this is a modal with all the available options to choose from
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Select Case Referal Type</h5>
<button type="button" class="close" data-dismiss="modal"><span>×</span>
</button>
</div>
<div class="modal-body">
<form id="checkboxForm" action="/save-checkboxes" method="POST">
@csrf
@foreach($referraltype as $type)
<input type="hidden" name="family_id" value="{{ $clients->id }}">
<input type="checkbox" name="options[{{ $family_id }}][]" value="{{$type -> id}}" id="checkbox_{{$type->id}}" >
<span style="margin-left: 10px;">{{ $type->referal_description }}</span>
<br>
@endforeach
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary" >Save changes</button>
</div>
</form>
</div>
</div>
</div>
this is my controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Family;
use App\Models\client_profile_ext;
use App\Models\referral;
class savereferraltype extends Controller
{
public function saveReferralCheckBoxes(Request $request){
$checkboxes = $request->input('options');
$family_id = $request->input('family_id');
$profile = client_profile_ext::where('family_id', $family_id)->first();
if(!$profile) {
$profile = new client_profile_ext();
$profile->family_id = $family_id;
}
$referralDescriptions = [];
foreach ($checkboxes as $option) {
$referral = referral::find($option);
if ($referral) {
$referralDescriptions[] = $referral->referal_description;
}
}
$profile->CaseReferalType = implode(', ', $referralDescriptions);
$profile->save();
return redirect()->back()->with('success', 'checkbox inserted successfully.');
}
}
this is my route
Route::post('/save-checkboxes', [savereferraltype::class,'saveReferralCheckBoxes']) -> name('savereferral');
this is where the results will be displayed after selecting the checkboxess
<tbody>
<tr>
<td>Case referal type:</td>
@foreach($crt as $type)
<td> {{$type -> CaseReferalType }}</td>
@endforeach
<td>
@include('modal')
<a href="#" class="edit-link" data-toggle="modal" data-target="#casereferalModal">
<i class="bi bi-pencil-fill bluepen"></i>
</a> </td>
</tr>
</tbody>
Then when the form is submitted, the checked values will be sent as an array in your controller:
public function someMethod(Request $request)
{
// Get checked values, grouped by family ID
$checkedOptions = $request->input('options');
}
You should probably also take care of naming your classes and sticking to naming conventions. Your controller class shouldn’t have an all-lowercase class name for example. It should be StudlyCase, i.e. SaveReferralType instead.
