[英]How to auto increment cart id in Laravel 5.6?
In Laravel 5.6, I installed shopping cart. 在Laravel 5.6中,我安装了购物车。 I want to put data as a session and then put a database. 我想将数据作为会话放置,然后再放置数据库。 I did something also but I could not get the id auto increment. 我也做了一些操作,但无法获得id自动递增。 It put in type. 它输入了。 When I input id then its work, but it is embarrassing to the user and not user-friendly. 当我输入id时,它就起作用了,但是它使用户感到尴尬,而且不友好。 I want to make it user-friendly 我想使其变得用户友好
Here's my code: 这是我的代码:
add.blade.php add.blade.php
<form action="{{route('add_to_cart')}}" method="post">
@csrf
<input type="text" name="hiddenId" value=""><br>
Name <br>
<input type="text" name="txtName"><br>
Qty <br>
<input type="text" name="txtQty"><br>
Price <br>
<input type="text" name="txtPrice">
<input type="submit" value=" + ">
</form>
<hr>
<table border="2px">
<tr>
<td>SL</td>
<td>Name</td>
<td>Qty</td>
<td>Unit Price</td>
<td>Total</td>
<td>Action</td>
</tr>
@foreach(Cart::content() as $row)
<tr>
<td>{{$row->id}}</td>
<td>{{$row->name}}</td>
<td>
<form action="{{url('update')}}" method="post">
{{csrf_field()}}
<input type="text" name="uqty" value="{{$row->qty}}">
<input type="hidden" name="rowId" value="{{$row->rowId}}">
<input type="submit" value="Update">
</form>
</td>
<td>{{$row->price}}</td>
<td>{{$row->subtotal}}</td>
<td>
<a href="{{url('deletecart/'.$row->rowId)}}">delete</a>
</td>
</tr>
@endforeach
<tfoot style="text-align: right;">
<tr>
<td colspan="2"> </td>
<td>Subtotal</td>
<td><?php echo Cart::subtotal(); ?></td>
</tr>
<tr>
<td colspan="2"> </td>
<td>Tax</td>
<td><?php echo Cart::tax(); ?></td>
</tr>
<tr>
<td colspan="2"> </td>
<td>Total</td>
<td><?php echo Cart::total(); ?></td>
</tr>
</tfoot>
</table>
CartController.php CartController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use DB;
use Cart;
use App\CartItem;
use Illuminate\Support\Facades\Auth;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class CartController extends Controller
{
function index(){
return view('add');
}
public function add_to_cart(Request $request){
$qty = $request->txtQty;
$id = $request->hiddenId;
$name = $request->txtName;
$price = $request->txtPrice;
$data['qty']=$qty;
$data['id']=$id;
$data['name']=$name;
$data['price']=$price;
Cart::add($data);
return redirect()->back();
}
public function update_cart(Request $request){
$uqty = $request->uqty;
$rowId = $request->rowId;
Cart::update($rowId, $uqty);
return redirect()->back();
}
public function delete_cart($rowId){
Cart::remove($rowId);
return redirect()->back();
}
}
Here route web.php 在这里路由web.php
Route::get('/addproduct','CartController@index')->name('cart_index');
Route::post('/addcart','CartController@add_to_cart')->name('add_to_cart');
//Route::post('/showcart','CartController@show_cart')->name('show_cart');
Route::get('/deletecart/{id}','CartController@delete_cart')->name('delete_cart');
Route::post('update','CartController@update_cart')->name('update_cart');
How can I achieve this? 我该如何实现?
migration: $table->increment('id');
迁移: $table->increment('id');
id should auto-increment unless public $increments = false;
id应该自动增加,除非public $increments = false;
in your model 在您的模型中
or just add 或只是添加
MODEL 模型
public $table = 'tablename';
public $fillable = ['your_stuff'];
public $increments = true;
i really do not understand the question, so it was worth a shot 我真的不明白这个问题,所以值得一试
