How to handle form submissions with validation in Laravel and vue js



Image not found!!

Handling form submissions with validation in Laravel and Vue.js involves a combination of server-side validation using Laravel and client-side validation using Vue.js. Below are the steps to achieve this:

1. Install Laravel and Set Up Vue.js

Make sure you have Laravel installed and set up. You can use Laravel Mix to manage your assets, including Vue.js.

bash
# Install Laravel Mix and Vue.js
composer require laravel/ui
php artisan ui vue
npm install && npm run dev

2. Create a Form Component in Vue.js

Create a Vue component for your form. This component will handle the form data and client-side validation.

javascript
// resources/js/components/ExampleForm.vue
<template>
    <form @submit.prevent="submitForm">
        <!-- Form fields go here -->

        <button type="submit">Submit</button>
    </form>
</template>

<script>
export default {
    data() {
        return {
            formData: {
                // Define form fields and their initial values here
            },
            errors: {}
        };
    },
    methods: {
        validateForm() {
            // Implement your client-side validation logic here
            // Update the 'errors' object with validation results
        },
        submitForm() {
            this.validateForm();

            if (Object.keys(this.errors).length === 0) {
                // Send form data to Laravel backend
                axios.post('/submit-form', this.formData)
                    .then(response => {
                        // Handle successful submission
                    })
                    .catch(error => {
                        // Handle submission error
                    });
            }
        }
    }
};
</script>

3. Set Up Laravel Validation

In your Laravel controller, validate the form data using Laravel's validation.

php
// app/Http/Controllers/FormController.php

use Illuminate\Http\Request;

class FormController extends Controller
{
    public function submitForm(Request $request)
    {
        $validatedData = $request->validate([
            // Define your validation rules here
        ]);

        // Process form data and return a response
    }
}

4. Create Routes

Define routes for your form in web.php:

php
// routes/web.php

use App\Http\Controllers\FormController;

Route::get('/form', function () {
    return view('form');
});

Route::post('/submit-form', [FormController::class, 'submitForm']);

5. Use the Vue Component in Blade View

Include the Vue component in your Blade view.

php
<!-- resources/views/form.blade.php -->

@extends('layouts.app')

@section('content')
    <example-form></example-form>
@endsection

6. Run Your Application

Run your Laravel application and visit the form page. The form component will handle both client-side and server-side validation.

bash
php artisan serve

This is a basic setup, and you might need to customize it based on your specific requirements. Make sure to check Laravel and Vue.js documentation for more advanced features and options.
