Individual ID's pdf print by Laravel8 - laravel

Question

I'm studying laravel using this gentleman's awesome code.
https://github.com/savanihd/Laravel-8-CRUD/blob/master/app/Http/Controllers/ProductController.php
I use Laravel Framework 8.48.2
I would like to add PDF pritabile view to each ID's "show" page
I could success PDF export using this simple test page.
public function generate_pdf() {
$pdf = \PDF::loadView('products.generate_pdf');
return $pdf->stream('yokoya_test.pdf');
}
so I had been trying to add PDF export to "show" function .
Here is my current code
Controller
public function each_print(Product $product)
{
$pdf = \PDF::loadView('products.each_print');
return $pdf->stream('each_print.pdf');
}
original index.blade.php code is this
<a class="btn btn-info" href="{{ route('products.show',$product->id) }}">Show</a>
I changed this as below
<a class="btn btn-info" href="{{ route('products.each_print',$product->id) }}">Print</a>
Here is my current WEB.php
Route::get('products/each_print', [ProductController::class, 'each_print']);
Route::resource('products', ProductController::class);
but I got this error
Symfony\Component\Routing\Exception\RouteNotFoundException
Route [products.each_print] not defined.
C:\xampp0827\htdocs\lara\ic0630-simple\vendor\laravel\framework\src\Illuminate\Routing\UrlGenerator.php:427
Could you teach me right code please?

Answer 1

you need define the name to the route like:
Route::get('products/each_print/{product}', [ProductController::class, 'each_print'])->name('products.each_print');
UPDATED
first refactor your code in the index blade table like:
<td>
<a class="btn btn-info" href="{{ route('products.show',$product->id) }}">detail</a>
<a class="btn btn-primary" href="{{ route('products.edit',$product->id) }}">edit</a>
<a class="btn btn-info" href="{{ route('products.each_print',$product->id) }}">Print</a>
<form action="{{ route('products.destroy',$product->id) }}" method="POST">
#csrf
#method('DELETE')
<i class="fas fa-trash-alt"></i>
<button type="submit" class="btn btn-danger">×</button>
</form>
</td>
and in the each_print function pass the product instance to the view like:
public function each_print(Product $product)
{
$pdf = \PDF::loadView('products.each_print', ['product' => $product]);
return $pdf->stream('each_print.pdf');
}
