Is there any way to extend the core functionalities without modifying the core files?

Hi there,
Is there any way to extend the core functionalities without modifying the core files?

Hello, @maulik1211,

If I understand correctly, you want to extend or modify the Core facade. If yes, you can do that by creating your own custom package and then extending the base core facade.

For example:

namespace {YourPackageName};

use Webkul\Core\Core as BaseCore;

class Core extends BaseCore
{
    // Write your own logic with the features of core functionalities.
}

Then, in your CustomPackageServiceProvider, bind the created facade like this:

use {YourPackageName}\Core;

public function register()
{
    $this->app->singleton('core', fn() => app(Core::class));
}

If you need any further help or clarification, feel free to ask!

Thank you for your prompt reply, and apologies for the lack of detail in my previous message.

I wanted to ask if there’s a way to make significant modifications to the existing CRM features. For example:

In the Create Lead form, I’d like to redesign it, add a new field like "Currency Type" (without using attributes), and update the logic for fetching and storing data.

Currently, we have "Products" connected to leads. Let's say I want to replace "Products" with "Services" instead.

Is it possible to implement such changes without modifying the core package (Packages/Webkul/{AnyExistingPackage}) so that updates won’t cause issues?

Looking forward to your guidance.

PS: I have checked the "Digging Deeper" section in the documentation.

Hello, @maulik1211,

Based on the provided information, you can make modifications as desired. If you want to redesign the lead creation form, you need to create a new controller within your custom package, as shown below:

Create a Custom Controller

namespace {YourPackage}\Controllers;

use Webkul\Admin\Http\Controllers\Controller;

class LeadController extends Controller 
{
    public function create()
    {
        return view('{your-package-view-namespace}::leads.create');
    }
}

Custom Blade Template

In your resources/leads/create.blade.php file, you can redesign the form or add additional fields according to your requirements.

Extend the Lead Model

If you want to add a new column to the Lead model, follow these steps:

1. Extend the Base Model:

   namespace {YourPackage}\Models;
   
   use Webkul\Lead\Models\Lead as BaseLead;
   
   class Lead extends BaseLead
   {
       protected $fillable = [
           // Add new columns here
       ];
   }

2. Create a Migration:

   Ensure you create a migration file to add the new column to the database schema.

3. Bind the Model in ServiceProvider:

   You need to bind your extended model in your custom package's ServiceProvider to ensure the application uses it:

   use Illuminate\Support\ServiceProvider;
   use {YourPackage}\Models\Lead;
   
   class YourPackageServiceProvider extends ServiceProvider
   {
       public function register()
       {
           $this->app->bind('Webkul\Lead\Contracts\Lead', Lead::class);
       }
   }

If you need any further help or clarification, feel free to ask!

Hi @suraj-webkul ,

Following your instructions, I created a package named "Category" (as outlined in the documentation, Just to tryout the answer).

Initially, I successfully accessed the URL /admin/category with the view file from my new module, which simply displayed "Hello World."

Next, I tried to override the leads.index view (instead of leads.create as mentioned earlier). I made all the necessary changes as per the instructions and tried accessing /admin/lead. However, I am still seeing the default leads.index view instead of my custom view located at: packages/Webkul/Category/src/Resources/views/index.blade.php.

Am I missing something, or did I misunderstand any step? Could you please guide me on this?
I am just wondering how the system will know that the original route 'admin\leads' should be overwritten and the custom view should be called.

Thank you!
