Laravel – How can I validate the inputs and redirect with custom message within the same url?

I have a Blade file accessed through a URL with a variable parameter. I want to check whether the input is blank with input validation and return to the same URL with a success/error message.

My blade file:
URL: http://localhost:8000/mypage?view=3
//3 is the ID used in the form below

<div>
    @if(Session::has('error'))
        <div class="error">
            {{ Session::get('error') }}
        </div>
        elseif(Session::has('success'))
        <div class="success">
            {{ Session::get('success') }}
        </div>
    @endif
</div>
<form action="{{route('action')}}" method="post">
    @csrf
    @foreach($data as $ldata)
        <label>ID
            <input type="text" name="id" readonly value="{{$ldata->id}}">
            <label>Status
                <select id="status" name="status">
                    <option value='Pending'>Pending</option>
                    <option value='Approved'>Approved</option>
                    <option value='Cancelled'>Cancelled</option>
                </select>
                <label>Remarks
                    <input type="text" name="remarks">
                    <button>Submit</button>
</form>

Controller:

public function take_action(Request $request ){
    $full_name = Auth::user()->full_name;
    $id = $request->input('id');
    $status = $request->input('status');
    $remarks = $request->validate(['remarks' => 'required']);
}

What I want to do is check for the validation, and if it’s a success, the controller should perform an update query followed by a redirect to the same URL (URL: http://localhost:8000/mypage?view=3) with a success message or if it fails, then with the error message.

    To achieve what you want, you can perform the validation in the controller, and then redirect back to the original URL with the appropriate success or error message. Here’s how you can modify your controller code:

    use IlluminateSupportFacadesRedirect;

public function take_action(Request $request){
    // Validate the request
    $validatedData = $request->validate([
        'remarks' => 'required',
    ]);

    // Extract data from the request
    $id = $request->input('id');
    $status = $request->input('status');
    $remarks = $validatedData['remarks'];

    // Perform your update query here

    // Assuming your update query is successful, set success message
    $successMessage = 'Update successful!';

    // Redirect back to the original URL with success message
    return Redirect::to('/mypage?view=' . $id)->with('success', $successMessage);

    // If the update query fails, you can redirect with an error message
    // $errorMessage = 'Update failed!';
    // return Redirect::to('/mypage?view=' . $id)->with('error', $errorMessage);
}

    This code first validates the request using the validate method, and if the validation is successful, it performs the update query. After the update query, it redirects back to the original URL with a success message.

    If the validation fails, Laravel will automatically redirect back to the previous page with the validation errors. You don’t need to handle this part explicitly unless you want to customize the error messages or the behavior. The default Laravel behavior is to redirect back with the old input and error messages.

    use IlluminateHttpRequest;
use IlluminateSupportFacadesRedirect;

class YourController extends Controller
{
    public function takeAction(Request $request)
    {
        $validatedData = $request->validate([
            'remarks' => 'required',
        ]);

        $id = $request->input('id');
        $status = $request->input('status');
        $remarks = $validatedData['remarks'];

        try {
            // Perform your update query here
            $successMessage = 'Update successful';
        } catch (Exception $e) {
            $errorMessage = 'Update failed: ' . $e->getMessage();
            
            return Redirect::to('/mypage?view=' . $id)->with('error', $errorMessage);
        }

        return Redirect::to('/mypage?view=' . $id)->with('success', $successMessage);
    }
}
    • Data is extracted from the request.
    • The ‘try’ block contains the code where you would perform your actual update query, If the query is successful, a success message is set
    • If an exception is caught, an error message is set, and the code redirects back to the original URL with the error message.
    • If the update query is successful, the code redirects back to the original URL with the success message.
