I am using laravel for a project i am making.
So i want that users can only create 30 products, and if they have more then 30 products, they cant create more products until they have removed some. What do i have to add in my code so that they cant add more products.

My Product controller

  public function store(Request $request)

{

    //check if user has more then 30 products



    $product = Product::create($request->all());

    $productPhotos = ;

    $photos = $request->post('photo');



    if (count($photos) <= 5) {

        foreach (range(1, $photos) as $i) {

            foreach ($photos as $imageData) {

                $bcheck = explode(';', $imageData);

                if (count($bcheck) > 1) {

                    list($type, $imageData) = explode(';', $imageData);

                    list(, $extension) = explode('/', $type);

                    list(, $imageData) = explode(',', $imageData);

                    $fileName = uniqid() . '.' . $extension;

                    $imageData = base64_decode($imageData);

                    Storage::put("public/products/$fileName", $imageData);

                    $imagePath = ('storage/products/' . $fileName);



                    $productPhotos = ProductPhoto::create([

                        'product_id' => $product->id,

                        'path' => $imagePath

                    ]);

                }

            }

        }

    } else {

        return response()->json("You cant add any photo's to your product", 400);

    }





    return response()->json([$product, $productPhotos], 201);

}

if i need to send some more code, let me know.

Thx in advance.

FINAL CODE:

   $totalProduct = Product::where('supplier_id', $request->user()->Supplier->id)->count();



    if ($totalProduct < 30){

        $product = Product::create($request->all());

        $productPhotos = ;

        $photos = $request->post('photo');





        if (count($photos)) {

            foreach ($photos as $i => $imageData) {



                if ($i >= 5) {

                    continue;

                }

                $bcheck = explode(';', $imageData);

                if (count($bcheck) > 1) {

                    list($type, $imageData) = explode(';', $imageData);

                    list(, $extension) = explode('/', $type);

                    list(, $imageData) = explode(',', $imageData);

                    $fileName = uniqid() . '.' . $extension;

                    $imageData = base64_decode($imageData);

                    Storage::put("public/products/$fileName", $imageData);

                    $imagePath = ('storage/products/' . $fileName);



                    $productPhotos = ProductPhoto::create([

                        'product_id' => $product->id,

                        'path' => $imagePath

                    ]);

                }



            }

        }

        return response()->json([$product, $productPhotos], 201);



    } else{

        return response()->json("you have to much products", 201);

    }



}

User Model

public function projects()

{

     return $this->hasMany('AppProject', 'id', 'user_id');

}

Project Model

public function users()

{

     return $this->belongsTo('AppUser', 'user_id', 'id');

}

Controller to Add projects

public function store(Request $request)

{

     $totalCreatedProjects = $request->user()->products->count();

     if ($totalCreatedProjects < 30) {

            `Your code to add projects here`

     }

     `Your code to alert maximum projects achieved here`    

}

This example assumed:

1. Your users are authenticated;

2. You created a database relationship 1 to many between Projects and Users;

Notes: When you compare to the amount of projects that exist and the number you wish to hold the creation instead of proceeding, this should be a service.
The number should be a constant with a proper semantic so other developers understand what you are trying to achieve

You can use this:

public function store(Request $request)

{

    if($request->user()->products->count() < 30) {



         //Add product

         ...



    }else{

        return redirect()->back();

    }

 }

public function store(Request $request)

{

    //check if user has more then 29 products

    if ($request->user()->products->count() >= 30) {

        return response()->json("You cant add more then 30 products", 400);

    }



    // Your code...

In User Model Add

public function canAddNewProduct()
{
return $this->products->count() < 30;
}

In Controller

Auth::guard('web')->user()->canAddNewProduct()

Better way of doing is make a new middleware and use

return Auth::guard('web')->user()->canAddNewProduct() ? true : false

to protect the routes
