Laravel 更改 URL 名称详细信息

Question

How do I make the post single URL like myweb.com/post-name instead myweb.com/post-id ? its works fine with posts id, but not with post name.

here my current route.

Route::get('/{id}', [App\http\Controllers\PostController::class, 'show']);

and here my controller.

public function show($id)
{
    $post = post::find($id);
    return view('detail', ['post' => $post]);
}

thank you.

Answer 1

That is because you are using the $id as the identifier to resolve the post object:

myweb.com/25

Then:

public function show($id) // $id = 25
{
    $post = post::find($id); // find() search for the PK column, "id" by default

    return view('detail', ['post' => $post]);
}

If you want to resolve the $post by a different field, do this:

public function show($name)
{
    $post = post::where('name', $name)->first();

    return view('detail', ['post' => $post]);
}

This should work for a route like this:

myweb.com/a-cool-post-name

As a side note, you could resolve the model automatically makin use of Route Model Binding .
