Unable to obtain instance of HTTP request in Laravel 5.8 - php

Question

I am having trouble retrieving form values using the Illuminate\Http\Request class.
I have an endpoint that creates a product and another that updates it set up like this
Route::post('products', 'ProductController#store');
Route::put('products/{product}', 'ProductController#update');
The store and update methods in the ProductController are
public function store(Request $request)
{
// validate inputs
$validator = Validator::make($request->all(), [
'name' => 'required',
'category' => 'required',
'status' => 'required',
'price' => 'required',
'image' => 'required|image|mimes:jpeg',
'interest' => 'required'
]);
// return 401 response if validation fails
if ($validator->fails()) {
return response()->json([$validator->errors()], 401);
}
// create & store the product
if ($product = Product::create([
'name' => $request->name,
'category' => $request->category,
'status' => $request->status,
'price' => $request->price,
'interest' => $request->interest,
])) {
// store the product image
$file = $request->file('image');
$destinationPath = "public/images/products";
$filename = 'pramopro_' . $product->name . '_' . $product->id . '.' . $file->extension();
Storage::putFileAs($destinationPath, $file, $filename);
ProductImage::create([
'product_id' => $product->id,
'name' => $filename
]);
}
// return new product
return new ProductResource($product);
}
public function update(Request $request, Product $product)
{
// dd($request);
// validate inputs
$validator = Validator::make($request->all(), [
'name' => 'required',
'category' => 'required',
'status' => 'required',
'price' => 'required',
'image' => 'required|image|mimes:jpeg',
'interest' => 'required'
]);
// return 401 response if validation fails
if ($validator->fails()) {
return response()->json([$validator->errors()], 401);
}
// update this product
if ($product) {
$product->update($request->all());
return new ProductResource($product);
} else {
return response()->json(["error" => "Not found"], 404);
}
}
Now when I test the endpoints in postman, I can successfully create a new product record. But if I try to update a product, I get a 401 unauthorized error even though all the required fields are filled. dd($request)returns null but dd($product) returns the product as expected.
Maybe I have been looking at it so hard so I have missed something. What am I doing wrong?

Answer 1

This is the reasons I think why the $request return null
The store and update request is same name. Two input name or select name or textarea name can't be the same name in the same web page. If its same it will always get the first one that is the reason why it is returning null because the first one is empty.
The name you're calling is incorrect
Hope it helps!
