如何在 laravel 中获取 URL 值？

Question

所以，我尝试了 laravel，但当我想获取 URL 值作为我的数据库的值时，我被卡住了。这是我控制器中的代码。

public function store(Request $request, $shoe_id)
{
    //Insert Data
    $cart = new Cart;
    
    $cart->user_id = Auth::user()->id;
    $cart->shoe_id = $shoe_id;
    $cart->quantity = $request->quan;

    $cart->save();

    return redirect()->back();
}

这是我遇到的问题： it says that the {shoe_id} is string where i wanted to be an integer from the URL

我的网站如下所示： My blade

这是我的 web.php：

Route::get('/','homeController@main')->name('home');
Route::get('/home','homeController@main')->name('home');
Route::get('/detail/{shoe_id}', 'homeController@detail');
Route::get('/cart/{shoe_id}','CartController@show');
Route::post('/cart/{shoe_id}','CartController@store');

这是我的刀片：

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div style="text-align:center;">
                    <img src="{{ asset("$cart->shoe_image") }}" alt="" style=" width:350px; height:350px;">
                    <div class="card-header">{{$cart->shoe_name}}</div>
                    <div class="card-header">${{$cart->shoe_price}}</div>
                    <div class="card-header">{{$cart->shoe_description}}</div>
                </div>
                <div class="card-header form-group">
                    <form method="POST" action="/cart/{shoe_id}" enctype="multipart/form-data">
                        @csrf
                        <div class="form-row">
                            <div class="col-md-2">
                                <label for="quantity">Quantity:</label>
                            </div>
                            <div>
                                <input class = "form-control" type="text" id="quantity" name="quan"><br><br>
                            </div>
                            <button class="btn btn-primary" type="submit" name="addcart">Add to Cart</button>
                        </div>
                    </form>
                    
                    {{-- <a class="btn btn-primary" href="#">Add to Cart</a> --}}
                    
                </div>
                
            </div>
        </div>
    </div>
</div>

我想要做的：将输入的数据输入数据库。我的数据库有一个名为 cart 的表，其属性为 id、user_id、shoe_id。

Answer 1

在您的表单操作中，您应该提供 shoe_id 的实际值，然后它将按预期工作。 action="/cart/{{ $cart->shoe_id }}"

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div style="text-align:center;">
                    <img src="{{ asset("$cart->shoe_image") }}" alt="" style=" width:350px; height:350px;">
                    <div class="card-header">{{$cart->shoe_name}}</div>
                    <div class="card-header">${{$cart->shoe_price}}</div>
                    <div class="card-header">{{$cart->shoe_description}}</div>
                </div>
                <div class="card-header form-group">
                    <form method="POST" action="/cart/{{ $cart->shoe_id }}" enctype="multipart/form-data">
                        @csrf
                        <div class="form-row">
                            <div class="col-md-2">
                                <label for="quantity">Quantity:</label>
                            </div>
                            <div>
                                <input class = "form-control" type="text" id="quantity" name="quan"><br><br>
                            </div>
                            <button class="btn btn-primary" type="submit" name="addcart">Add to Cart</button>
                        </div>
                    </form>
                    
                    {{-- <a class="btn btn-primary" href="#">Add to Cart</a> --}}
                    
                </div>
                
            </div>
