Redirecting users through form inputs is a typical necessity in web applications since it allows you to preserve data consistency and improve user experience when going between different pages or actions. Laravel 10, a versatile PHP framework, includes techniques for efficiently redirecting with form inputs.

We will walk you through the process of redirecting with form inputs in Laravel 10, allowing you to easily transfer data between requests and improve the user experience.

Throughout this lesson, we’ll look at how to redirect with form inputs in Laravel 10, including how to utilise the withInput function, how to handle validation problems, and how to keep user-entered data across requests.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Setup Form Data Controller

Back to project terminal and run this command to create a controller class file,

php artisan make:controller BlogController

It will create a file i.e BlogController.php inside /app/Http/Controllers folder.

Open file and write this complete code into it,

<?php

namespace App\Http\Controllers;

//use App\Models\Blog;
use Illuminate\Http\Request;
use Illuminate\View\View;

class BlogController extends Controller
{
    public function index(): View
    {
        return view('blog-form');
    }

    public function submitData(Request $request)
    {
        $validatedData = $request->validate([
            'title' => 'required',
            'description' => 'required',
            'author_name' => 'required'
        ]);

        // $blog = new Blog();

        // $blog->title = $request->title;
        // $blog->description = $request->description;
        // $blog->author_name = $request->author_name;

        // $blog->save();

        return redirect('form')->with('success', 'Data saved successfully!')->withInput();
    }
}

Concept

Redirect to route with form inputs,

return redirect('form')->with('success', 'Data saved successfully!')->withInput();

Alternative,

return back()->with('success','Data saved successfully!')->withInput();

Next,

Setup Blade Template with Form Inputs

Create a blade template file blog-form.blade.php inside /resources/views folder.

Open file and write this code into it,

<html lang="en">

<head>
    <title>Laravel 10 How To Redirect with Form Inputs Tutorial</title>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" rel="stylesheet">
</head>

<body>
    <div class="container" style="margin-top: 20px;">
        <div class="row">
            <div class="col-md-12">
                @if (Session::has('success'))
                <div class="alert alert-success">
                    {{ Session::get('success') }}
                    @php
                    Session::forget('success');
                    @endphp
                </div>
                @endif
                <h4 class="text-center">Laravel 10 How To Redirect with Form Inputs Tutorial</h4><br>
                <form method="post" action="{{ route('blog.submit') }}" class="form form-horizontal">
                    @csrf
                    <div class="form-group">
                        <label>Title</label>
                        <input type="text" name="title" class="form-control" value="{{ old('title') }}"/>
                    </div>
                    <div class="form-group">
                        <label>Description</label>
                        <textarea class="form-control" id="description-ckeditor" name="description">{{ old('description') }}</textarea>
                    </div>
                    <div class="form-group">
                        <label>Author Name</label>
                        <input type="text" name="author_name" class="form-control" value="{{ old('author_name') }}" />
                    </div>
                    <div class="form-group">
                        <input type="submit" value="Submit" class="btn btn-primary" />
                    </div>
                </form>
            </div>
        </div>
    </div>
    <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
    <script src="https://cdn.ckeditor.com/4.15.1/standard/ckeditor.js"></script>
    <script>
    CKEDITOR.replace('description-ckeditor');
    </script>
</body>

</html>

Concept (Get old data)

Using old() helper function it will show the old submitted form data.

{{ old('field_name') }}

Add Route

Open web.php from /routes folder. Add these routes into it,

//...

use App\Http\Controllers\BlogController;

Route::get('form', [BlogController::class, 'index']);
Route::post('submit', [BlogController::class, 'submitData'])->name("blog.submit");
//...

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL: http://127.0.0.1:8000/form

It will open form. Once you submit form with data. Form will be submitted and redirect back with inputted values.

That’s it.
