Laravel - How to get checkboxes value with the same name properly? - laravel

Question

My model (table with 2 primary keys and are foreign key on the same time) :
class FormationPersonnel extends Model
{
protected $fillable = ['cin', 'id_form'];
public $incrementing = false;
}
I create checkboxes with JQuery, Ajax like so :
var grabData = "";
for (let i = 0; i < data.length; i++) {
grabData +=
`<div class="col-lg-4 col-sm-6">
<div class="custom-control custom-checkbox">
<input type="checkbox" name="cin[]" id="`+data[i]["cin"]+`" class="custom-control-input" value="`+data[i]["cin"]+`">
<label for="`+data[i]["cin"]+`" class="custom-control-label">`+data[i]["cin"]+' '+data[i]["nom"]+' '+data[i]["prenom"]+`</label>
</div>
</div>`;
}
personnelsInput.html("");
personnelsInput.append(grabData);
which I give the checkboxes the same name as :
name="cin[]"
In My controller I use this code, but is not storing any data from checkboxes :
$cins = $request->cin; //I get inputs like this
foreach ($cins as $cin) {
$form_pers = new FormationPersonnel; //create new record
if ($request->has($cin)) {
$form_pers->id_form = $request->input('id_form');
$form_pers->cin = $request->input($cin);
$form_pers->save(); //save data
}
}
What is the correct way ?

The correct way to check whether the Model has cin or not is
Edited
based on the comment we put, I think I know what you're trying to do, so do it like below code to get what you need.
note
you don't know what $cins values so that's why you use if(). No need to check whether the user check (checkbox) or not. because the checked value only send by form. please try to know what data you have in your variable before coding.
I recommended you to use dd() or print_r() or others https://laraveldaily.com/echoing-dd-vs-var_dump-vs-print_r/ to check the data you got in your variable.
$cins = $request->cin; //getting all checked (from checkbox) data
foreach ($cins as $cin) {
$form_pers = new FormationPersonnel; //new model
$form_pers->id_form = $request->id_form; //get name="id_form" from form
$form_pers->cin = $cin; //put cin value (loop)
$form_pers->save(); //save
}
