In Laravel 9, how to insert data into a database [closed]

Q

I am working with Laravel 9. I am trying to insert data into database. It is not user data, data will be inserted into database on form submit button.

My view:

    <form action="{{ route('store.category') }}" method="POST">
    @csrf
    <div class="mb-3">
    <label for="categoryName" class="form-label">Category Name</label>
    <input type="text" class="form-control" id="category_name" placeholder="Enter Category Name">
    @error('category_name')
    <span class="text-danger">{{ $message }}</span>
    @enderror
    </div>
    <button type="submit" style="float: right;" class="btn form-control btn-primary">Add</button>
    </form>

My web.php:

Route::post('/category/add', [CategoryController::class, 'AddCat'])->name('store.category');

My model

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Category extends Model
{
protected $table = 'categories';
use SoftDeletes;
protected $fillable = [
    'user_id',
    'category_name'
];

} My table migration:

public function up()
{
    Schema::create('categories', function (Blueprint $table) {
        $table->id();
        $table->integer('user_id');
        $table->string('category_name');
        $table->timestamps();
        $table->SoftDeletes();
    });
}

My controller:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Category;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Carbon;
use Illuminate\Support\Facades\DB;

class CategoryController extends Controller

{

public function AddCat(Request $request)
{
    $validated = $request->validate([
        'category_name' => 'required|unique:categories|max:255',
    ]);

First i tried this

    $category = Category::create([
        'user_id'       => Auth::user()->id,
        'category_name' => $request->category_name,
    ]);
    $category->save();

Then this

    $category = new Category;
    $category->user_id = Auth::user()->id;
    $category->category_name = $request->category_name;
    $category->save();

Then this

    $user_id = Auth::user()->id;
    $category_name = $request->input('category_name');
    $data=array("user_id"=>,"$user_id"=>$category_name);
    DB::table('categories')->insert($data);
}

}

But the data not inserting into database. The command is showing the below every time the form is submitted

Can someone help me with the solution

Found the answer. The issue created due to my stupidity!

    <input type="text" class="form-control" id="category_name" placeholder="Enter Category Name">

Forgot to put name attribute in the input tag

    <input type="text" class="form-control" name="category_name" id="category_name" placeholder="Enter Category Name">
