Add a limit to users creating a item - php

Question

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('App\Project', 'id', 'user_id');
}
Project Model
public function users()
{
return $this->belongsTo('App\User', '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

Answer 2

You can use this:
public function store(Request $request)
{
if($request->user()->products->count() < 30) {
//Add product
...
}else{
return redirect()->back();
}
}

Answer 3

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...

Answer 4

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
