My controller name is "CategorieController". This is the store function sauvercategorie in my CategorieController.

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppModelsCategorie;


class CategorieController extends Controller
{
    //

    public function ajoutercategorie(){
        return view('admin.ajoutercategorie');
    }

    public function sauvercategorie(Request $request){

        $validatedData = $request->validate([
            'category_name' => 'required | max:255',
        ]);

        $categorie = Categorie::create($validatedData);


        return redirect('/ajoutercategorie')->with('status', 'La catégorie'
        .$categorie->category_name.'a été ajoutée avec succès');

My entire blade file.

The name of the model is Category. This is my model

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Categorie extends Model
{
    use HasFactory;
        protected $fillable = ['category_name'];
}

My table name is "categories". This is my table

use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateSupportFacadesSchema;

class CreateCategoriesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('categories', function (Blueprint $table) {
            $table->id();
            $table->string('categorie_name');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('categories');
    }
}

Need help, thank you.

Answer 1

In migration and model, your field names are different.

Change your model to:

protected $fillable = ['category_name'];

changed to:

protected $fillable = ['categorie_name'];
