Published: 2023-07-11 17:42:09

In [the last post](https://flixtechs.co.zw/posts/laravel-ecommerce-tutorial-part-62-listing-and-deleting-products), we added the ability to list all products, search with Scout and Spatie Query Builder, the ability to delete products. This part 6.3 of the on building an ecommerce website in Laravel from start to deployment.

In this post we will continue to add the ability to edit products.

Let's dive in

Head over to `Admin\ProductController` and edit the `edit` action and tell laravel to return the edit page

```php
/**
 * Show the form for editing the specified resource.
 *
 * @param Product $product
 * @return Renderable
 */
public function edit(Product $product)
{
    $categories = Category::all();

    return view('admin.products.edit', [
        'product' => $product,
        'categories' => $categories
    ]);
}
```

Then let's edit the `admin.products.edit` view, the markup will be the same as the `create` view except this time we pre populate the fields and submit the form to the update action

Add the following snippet to your edit view

```html
@extends('layouts.app')

@section('title')
    Edit Product
@endsection

@section('content')
    <section class="section">
        <div class="section-header">
            <div class="section-header-back">
                <a href="{{ route('admin.products.index') }}"
                   class="btn btn-icon"><i class="fas fa-arrow-left"></i></a>
            </div>
            <h1>
                Edit Product
            </h1>
            <div class="section-header-breadcrumb">
                <div class="breadcrumb-item active"><a href="#">Dashboard</a></div>
                <div class="breadcrumb-item"><a href="{{ route('admin.products.index') }}">Products</a></div>
                <div class="breadcrumb-item">
                    Edit Product
                </div>
            </div>
        </div>

        <div class="section-body">
            <h2 class="section-title">
                Edit Product
            </h2>

            <p class="section-lead">

```

Next, we edit the `UpdateProductRequest` to add some validation and authorizations to the request before it reaches the controller

Edit the `UpdateProductRequest` to the following

```php
<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class UpdateProductRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize(): bool
    {
        return $this->user()->can('update', $this->route('product'));
    }

    /**
     * Prepare input for validation
     *
     * @return void
     */
    protected function prepareForValidation(): void
    {
        $this->merge([
            'track_quantity' =>
                $this->has('track_quantity') &&
                $this->input('track_quantity') == 'on',
            'sell_out_of_stock' =>
                $this->has('sell_out_of_stock') &&
                $this->input('sell_out_of_stock') == 'on',
        ]);
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array<string, mixed>
     */
    public function rules(): array
    {
        return [
            'name' => 'required|string|max:255',
            'description' => 'required|string',
            'sku' =>
                'sometimes|nullable|string|unique:products,sku,' .
                $this->route('product')->id,
            'track_quantity' => 'sometimes|nullable|boolean',
            'quantity' => 'required_if:track_quantity,true|nullable|int',
            'sell_out_of_stock' => 'required_if:track_quantity,true|boolean',
            'category_id' => 'required|int|exists:categories,id',
            'price' => 'required|numeric|min:0',
            'cost' => 'sometimes|nullable|numeric',
            'discounted_price' => 'sometimes|nullable|numeric',
            'status' => 'required|string|in:active,draft,review',
            'images' => 'sometimes|nullable|array',
            'images.*' => 'string',
        ];
    }
}
```

So on the authorize method we check if the user authorized to update products, we don't anyone just products if they are not authorized.

The `prepareForValidation` method simply turns the input checks ("on") into real booleans and then your everyday validation on the rules method

If validation passes let's make the actual updating in the `Admin\ProdocutController`.

Edit the `update` method and put the following snippet

```php

/**
 * Update the specified resource in storage.
 *
 * @param UpdateProductRequest $request
 * @param Product $product
 * @return RedirectResponse
 * @throws Exception
 */
public function update(UpdateProductRequest $request, Product $product)
{
    $product->update($request->safe()->except(['images']));

    collect($request->validated('images'))->each(function ($image) use (
        $product,
    ) {
        $product->attachMedia(new File(storage_path('app/' . $image)));
        Storage::delete($image);
    });

    return to_route('admin.products.index')->with(
        'success',
        'Product was successfully updated',
    );
}
```

First we get the validated fields from the request except the images key and pass that to the update method of the product model

If there were images uploaded with this request we loop through all of them and then attach them to this product

Lastly, we return the user to the products index page with a toast message.

This is all we need to be able to edit products and in the upcoming tutorials we will add the ability to create product variations such as color, size etc

As I was using the products section of the ecommerce website I noticed a few issues if a user doesn't include optional fields which we will rectify in the next post
