Livewire 3 for Beginners with Laravel 12 Starter Kit

Edit Form: Pass Parameters to Component

Summary of this lesson:
- Creating edit functionality for existing company records
- Passing model data from controllers to Livewire components
- Populating form fields with existing values from database
- Implementing update functionality with similar validation rules

It's time to create the form to edit the company and pass the parameter from the URL to the Livewire component.

Company ID: From URL to Livewire

Imagine we have a URL /companies/1/edit, and our resourceful Controller looks like this.

app/Http/Controllers/CompanyController.php:

namespace App\Http\Controllers;
 
use App\Models\Company;
 
class CompanyController extends Controller
{
    public function create()
    {
        return view('companies.create');
    }
 
    public function edit(Company $company) 
    { 
        return view('companies.edit', compact('company', 'countries')); 
    } 
}

We get the $company with Laravel's Route Model Binding.

Now, the question is: in the Blade file, how do we pass the parameter to the Livewire component?

I've created a new edit.blade.php, almost copy-pasting everything from the create.blade.php. I know it's a code duplication, but we will optimize this when discussing full-page components and layouts in the upcoming lessons.

Here's the syntax.

resources/views/companies/edit.blade.php:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Simple Form</title>
    <script src="https://cdn.tailwindcss.com"></script>
</head>
<body class="flex items-center justify-center min-h-screen bg-gray-100">
    <livewire:company-edit :company="$company" />
</body>
</html>

See that line?

<livewire:company-edit :company="$company" />

So yeah, we will create a new Livewire component:

php artisan make:livewire CompanyEdit

We can pass parameters with the syntax...
