Answer 1

Your are doing wrong in blade file. Note here php array start from 0. So array is [0,1,2,3] and database id is start from 1.

Answer 2

this is the correct link
{{ route('product.show', ['Product' => $product->id]) }}

Answer 3

You have to use like below code
{{ route('product.show', ['id' => $product->id]) }}
return view('product.show', compact('product'));
And in your show.blade.php you have to use like below
{{$product->id}} or {{$product->name}} //etc //But not use foorloop

Answer 4

The find method will return only one item. You can't use the loop on it.
Try the following code.
web.php
Route::get('/product/{product}', 'ProductController#show')->name('product.show');
ProductController.php
public function show(Product $product)
{
return view('product.show')->with(compact('product'));
}
home.blade.php
<div class="row">
<div class="col-lg-4 col-md-6 mb-4">
<div class="card h-100">
<img class="card-img-top" src="http://placehold.it/700x400" alt="">
<div class="card-body">
<h4 class="card-title">
{{ $product->name }}
</h4>
<h5>{{ $product->price }}</h5>
<p class="card-text">{{ $product->description }}</p>
<td><a class="btn btn-primary" href="{{ route('product.show', $product->id ) }}">Show</a></td>
</div>
<div class="card-footer">
<small class="text-muted">★ ★ ★ ★ ☆</small>
</div>
</div>
</div>
</div>

Answer 5

you are in wrong blade
you are returning product.show blade in your controller:
return view('product.show')->with(compact('product'));
but you put home.blade code!!!
put the right blade code

Answer 6

show.php: Why not try it $_ Get["id"]
