Laravel 11 E-Commerce Project - Admin Edit Coupon

Welcome back to the Laravel E-Commerce Project Tutorial. In this video, we will learn about creating an admin edit coupon feature.

Step 1: Create a Function in the AdminController

First, let's create a new function in the AdminController:

public function edit_coupon($id)
{
       $coupon = Coupon::find($id);
       return view('admin.coupon-edit',compact('coupon'));
}

Step 2: Create a Route for the Function

Next, create a route for this function:

Route::put('/admin/coupon/update',[AdminController::class,'update_coupon'])->name('admin.coupon.update');

Step 3: Create a View for Editing a Coupon

Now, go to the resources directory and create a new file called coupon-edit.blade.php. Open the coupon-add.blade.php file and copy all the content from there, then paste it inside the coupon-edit.blade.php file. Make the following changes:

@extends('layouts.admin')
@section('content')
<div class=`main-content-inner`>
    <!-- main-content-wrap -->
    <div class=`main-content-wrap`>
        <div class=`flex items-center flex-wrap justify-between gap20 mb-27`>
            <h3>Coupon infomation</h3>
            <ul class=`breadcrumbs flex items-center flex-wrap justify-start gap10`>
                <li>
                    <a href=`{{route('admin.index')}}`><div class=`text-tiny`>Dashboard</div></a>
                </li>
                <li>
                    <i class=`icon-chevron-right`></i>
                </li>
                <li>
                    <a href=`{{route('admin.coupons')}}`><div class=`text-tiny`>Coupons</div></a>
                </li>
                <li>
                    <i class=`icon-chevron-right`></i>
                </li>
                <li>
                    <div class=`text-tiny`>Edit Coupon</div>
                </li>
            </ul>
        </div>        
        <!-- new-category -->
        <div class=`wg-box`>
            <form class=`form-new-product form-style-1` method=`POST` action=`{{route('admin.coupon.update')}}` >
                @csrf
                @method(`put`)
                <input type=`hidden` name=`id` value=`{{$coupon->id}}` />
                <fieldset class=`name`>
                    <div class=`body-title`>Coupon Code <span class=`tf-color-1`>*</span></div>
                    <input class=`flex-grow` type=`text` placeholder=`Coupon Code` name=`code` tabindex=`0` value=`{{$coupon->code}}` aria-required=`true` required=``>
                </fieldset>
                <fieldset class=`category`>
                    <div class=`body-title`>Coupon Type</div>
                    <div class=`select flex-grow`>
                        <select class=`` name=`type`>
                            <option value=``>Select</option>
                            <option value=`fixed` {{$coupon->type=='fixed'? 'selected':''}}>Fixed</option>
                            <option value=`percent` {{$coupon->type=='percent'? 'selected':''}}>Percent</option>
                        </select>
                    </div>
                </fieldset>
                <fieldset class=`name`>
                    <div class=`body-title`>Value <span class=`tf-color-1`>*</span></div>
                    <input class=`flex-grow` type=`text` placeholder=`Coupon Value` name=`value` tabindex=`0` value=`{{$coupon->value}}` aria-required=`true` required=``>
                </fieldset>
                <fieldset class=`name`>
                    <div class=`body-title`>Cart Value <span class=`tf-color-1`>*</span></div>
                    <input class=`flex-grow` type=`text` placeholder=`Cart Value` name=`cart_value` tabindex=`0` value=`{{$coupon->cart_value}}` aria-required=`true` required=``>
                </fieldset>
                <fieldset class=`name`>
                    <div class=`body-title`>Expiry Date <span class=`tf-color-1`>*</span></div>
                    <input class=`flex-grow` type=`date` placeholder=`Expiry Date` name=`expiry_date` tabindex=`0` value=`{{$coupon->expiry_date}}` aria-required=`true` required=``>
                </fieldset>                
                
                <div class=`bot`>
                    <div></div>
                    <button class=`tf-button w208` type=`submit`>Save</button>
                </div>
            </form>
        </div>
        <!-- /new-category -->
    </div>
    <!-- /main-content-wrap -->
</div>                    
</div>
@endsection

Step 4: Create a Function for Updating the Coupon

Now, go to the AdminController and create a new function for updating the coupon:

public function update_coupon(Request $request)
{
       $request->validate([
       'code' => 'required',
       'type' => 'required',
       'value' => 'required|numeric',
       'cart_value' => 'required|numeric',
       'expiry_date' => 'required|date'
       ]);
       $coupon = Coupon::find($request->id);
       $coupon->code = $request->code;
       $coupon->type = $request->type;
       $coupon->value = $request->value;
       $coupon->cart_value = $request->cart_value;
       $coupon->expiry_date = $request->expiry_date;               
       $coupon->save();           
       return redirect()->route('admin.coupons')->with('status','Record has been updated successfully !');
}

Step 5: Create a Route for Updating the Coupon

Next, create a route for this update_coupon function:

Route::put('/admin/coupon/update',[AdminController::class,'update_coupon'])->name('admin.coupon.update');

Step 6: Update the Coupon Edit View

Now, go to the coupon-edit.blade.php file and set the form method and action:

method=`POST` action=`{{route('admin.coupon.update')}}`

Also, add the @method directive and pass the method name:

@method(`PUT`)

Step 7: Add an Edit Link

Finally, add an edit link. Go to the coupons.blade.php file and inside the foreach loop, add the edit link:

<td>
       <div class=`list-icon-function`>                                        
              <a href=`{{route('admin.coupon.edit',['id'=>$coupon->id])}}`>
                     <div class=`item edit`>
                     <i class=`icon-edit-3`></i>
                     </div>
              </a>       
       </div>
</td>

Now it's done! Let's check it out. Go to the /admin/coupons page, edit a coupon, make some changes, and click on update. You can see that the coupon has been updated.

In this way, you can edit a coupon.

That's all about editing a coupon.
