Update does not work in Laravel, If I use different textbox name than column name in database

Question

My table country has two fields country_id and country_name.

the textbox is using name country

<input type="text" class="form-control" value="{{Session::get('name')}}" name="country" >

CountryCOntroller code is

public function update(Request $request, $id)
{
 $this->validate($request, [
 'country' => 'required|country_name',
  ]);
   $updateCountry = $request->all();

    //update  data
    country::find($id)->update($updateCountry);
    return redirect('/admin/country');
}

my model is

 class country extends Model
{
protected $table = 'country';
protected $fillable = ['country_name'];
public $timestamps = false;
protected $primaryKey = 'country_id';
}

Answer 1

you need to change the name in the input filed to country_name as it should match the column name so it should be like this,

<input type="text" class="form-control" value="{{Session::get('name')}}" name="country_name" >

If you don't want to change that then you should change you controller where you send the array in to the update method. so something like this,

public function update(Request $request, $id)
{
 $this->validate($request, [
 'country' => 'required',
  ]);


    //update  data
    country::find($id)->update([
'country_name' => $request->country
]);
    return redirect('/admin/country');
}
