Livewire Development Tutorials, Guides & Insights

• Target a specific component by passing its name or ID:

   $this->emitTo('componentName', 'eventName', $optionalData);

This ensures that Summernote is properly loaded and ready to use in your application.

<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\Models\Post;

class SearchPosts extends Component
{
    public $query = '';
    public $posts = [];

    public function updatedQuery()
    {
        $this->posts = Post::where('title', 'like', '%' . $this->query . '%')->get();
    }

    public function render()
    {
        return view('livewire.search-posts');
    }
}

Next, create the Blade view for this component in resources/views/livewire/search-posts.blade.php.

• Category Selection: The selectedCategory property is bound to the category dropdown. When a category is selected, the updatedSelectedCategory method is triggered.
• Dynamic Subcategory Loading: The updatedSelectedCategory method calls getSubcategories to fetch the corresponding subcategories based on the selected category. The subcategories property is then updated, which dynamically updates the subcategory dropdown in the view.
• Livewire Magic: Livewire automatically listens to the changes in the selectedCategory property and re-renders the relevant parts of the view without a full page reload.

Using Livewire to create dynamic forms is a powerful way to improve user experience by updating form fields in real-time based on user input. This tutorial demonstrated how to set up a dynamic dropdown menu in Laravel using Livewire, but the principles can be applied to any form field.

We'll create a system to open and close modals using Livewire and JavaScript by dispatching custom events.

Create a Livewire component, or use an existing one where you want to manage modals.
