# Views

# Introduction

Views in Laravel are responsible for separating the application's logic from the presentation layer. They provide a clean way to manage and organize the HTML content of your application. Views are typically stored in the resources/views directory and are rendered using the Blade templating engine, which offers a simple and powerful way to create dynamic content.

By using views, you can create reusable templates and components, making your code more maintainable and easier to understand. Blade templates allow you to use control structures like loops and conditionals, as well as to include other templates, which helps to keep your views organized and modular.

To learn in detail about Views, you can visit the Laravel documentation here (opens new window).

Here's a basic example of a Blade template:

# Directory Structure

To organize the views for our Category package, we need to set up a specific directory structure. Follow the steps below to create the necessary directories.

# Create the Resources Directory

  • Navigate to the packages/Webkul/Category/src directory.
  • Create a directory named Resources.

# Create the views Directory

  • Inside the Resources directory, create another directory named views and inside the views directory create category directory.
  • Inside the views/category directory, create a file named index.blade.php, create.blade.php, edit.blade.php .

The updated directory structure will look like this:

  └── packages
      └── Webkul
          └── Category
              └── src
                  ├── ...
                  └── Resources
                      └── views
                          └── category
                              ├── create.blade.php
                              ├── edit.blade.php
                              └── index.blade.php

# Adding HTML Content

Below is an example of basic HTML content that you can add to each index.blade.php file.

# index.blade.php in the category Directory

@extends('admin::layouts.master')

@section('page_title')
    {{ __('category::app.categories.index.title') }}
@endsection

@section('content-wrapper')

@endsection

# Load Views from Package

To make the views in our package accessible, we need to register them in the service provider's boot method. This involves updating the CategoryServiceProvider.php file to include the view loading logic. Follow the steps below:

# Open the Service Provider File

  • Navigate to the packages/Webkul/Category/src/Providers directory.
  • Open the CategoryServiceProvider.php file.

# Update the boot Method

  • Inside the boot method of the CategoryServiceProvider class, add the logic to load views from the package.

# Updated CategoryServiceProvider.php

Here is the updated code for CategoryServiceProvider.php:

<?php

namespace Webkul\Category\Providers;

use Illuminate\Support\ServiceProvider;

class CategoryServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        // ... 

        $this->loadViewsFrom(__DIR__ . '/../Resources/views', 'category');
    }
}

# Explanation

  • The namespace keyword defines the namespace for the CategoryServiceProvider class, which is Webkul\Category\Providers.

  • The CategoryServiceProvider class extends Laravel's base ServiceProvider class.

  • The boot method is used to bootstrap any application services.

  • Inside the boot method, we use the $this->loadViewsFrom method to register the views from the package.

  • The loadViewsFrom method takes two arguments:

    • The path to the views directory within the package: __DIR__ . '/../Resources/views'.
    • A namespace for the views: 'category'.

# Rendering Views

In Laravel applications, views are typically rendered from controller methods using the view helper function. This section describes how views are invoked and passed data from a controller.

<?php

namespace Webkul\Category\Http\Controllers;

use Illuminate\View\View;
use Webkul\Category\Http\Controllers\Controller;
use Webkul\Category\Repository\CategoryRepository;

class CategoryController extends Controller
{
    /**
     * Create a controller instance.
     * 
     * @return void
     */
    public function __construct(protected CategoryRepository $categoryRepository)
    {
    }

    /**
     * Display the listing of the resource.
     */
    public function index(): View
    {
        $categories = $this->categoryRepository->with(['author'])->all();

        return view('category::category.index', compact('categories'));
    }
}

# Explanation

  • The view helper function in Laravel is used within the index method of the CategoryController to render the category::category.index view.

  • It accepts two parameters the name of the view (category::category.index) and an array of data (compact('categories')) to pass to the view.

# Blade File Naming Convention

Krayin utilizes Blade templates to handle listing, creation, and updating operations for resources like products, leads, persons, organizations, and categories. This section provides a detailed guide on how to implement these operations using Blade templates within your Krayin package.

# Listing (Index Blade):

  • The index.blade.php template is used to display a list of all records (categories).

  • The controller's index method fetches all categories and passes them to the view.

# Creation (Create Blade):

  • The create.blade.php template contains a form for creating new records.

  • The controller's create method renders this view.

# Updating (Edit Blade):

  • The edit.blade.php template contains a form for editing existing records.

  • The controller's edit method fetches the specific categories and passes it to the view.

By following these steps, you can effectively utilize Blade templates in Krayin for listing, creating, and updating resources, ensuring a structured and maintainable approach to managing CRUD operations within your application.
