Check if at least one input has value with laravel controller - laravel

Question

I have a simple form where the user should be able to only fill the inputs he wants but if the form hasn't at least one input filled, it should return a error message saying that the form can't be empty if he clicks the submit button.
Here's my form:
#if ($message = Session::get('success'))
<div class="alert alert-success alert-block">
<strong>{{ $message }}</strong>
</div>
#endif
</center>
<form action="{{ route('send-update') }}" method="POST" enctype="multipart/form-data"> #csrf
<label>Nome do projeto:</label>
<div class="input-group mb-3"><br>
<input type="text" class="form-control" name="project_name" aria-label="Username" aria-describedby="basic-addon1">
</div>
#error('project_name')
<div class="text-danger" style="float:left; margin-top:-10px" role="alert">
<small> {{$message}}</small>
</div>
#enderror
<br>
<label>Descrição:</label>
<div class="input-group mb-3"><br>
<textarea class="form-control" name="desc" aria-label="With textarea"></textarea>
</div>
#error('desc')
<div class="text-danger" style="float:left; margin-top:-10px" role="alert">
<small> {{$message}}</small>
</div>
#enderror
<br>
<label>Tem alguma imagem que queira mudar/inserir?</label>
<div class="input-group mb-3">
<input type="file" name="img" accept="image/*" class="form-control" id="inputGroupFile01">
</div>
#error('img')
<div class="text-danger" style="float:left; margin-top:-10px" role="alert">
<small> {{$message}}</small>
</div>
#enderror
<div class="input-group mb-3">
<input type="text" class="form-control" name="img_desc" placeholder="Diga-nos onde pretende mudar/adicionar">
</div>
#error('img_desc')
<div class="text-danger" style="float:left; margin-top:-10px" role="alert">
<small> {{$message}}</small>
</div>
#enderror
<br>
<label>Tem mais informações? Insira um arquivo .txt, docx ou pdf</label>
<div class="input-group mb-3">
<input type="file" name="ficheiro" accept=".xlsx,.xls,.doc, .docx,.ppt, .pptx,.txt,.pdf" class="form-control" id="inputGroupFile01">
</div>
#error('ficheiro')
<div class="text-danger" style="float:left; margin-top:-10px" role="alert">
<small> {{$message}}</small>
</div>
#enderror
<br>
<input type="hidden" name="id" value="{{ request('id') }}">
<center> <button type="submit" class="btn btn-secondary ">Fazer pedido de atualização</button></center><br>
</form>
And here's the controller:
public function sendUpdate(Request $request){
$id = $request['id'];
$order = Order::where('id', $id)->first();
$validator = Validator::make($request->all(), [
'project_name' => ['nullable', 'string', 'max:255', 'regex:/^[a-zA-Z]+$/u]'],
'desc' => ['nullable', 'string', 'max:255', 'regex:/^[a-zA-Z]+$/u]'],
'img' => ['nullable', 'image', 'mimes:jpeg,png,jpg,svg', 'max:1024'],
'img_desc' => ['nullable', 'string', 'max:255', 'regex:/^[a-zA-Z]+$/u]'],
'ficheiro' => ['nullable', 'csv,txt,xlx,xls,pdf', 'max:2048'],
]);
if (request()->hasFile('ficheiro')){
if (request()->file('ficheiro')->isValid())
{
$fileName = $request->file('ficheiro')->getClientOriginalName();
$path = $request->file('ficheiro')->storeAs('files', $fileName, 'public');
}}
if (request()->hasFile('img')){
if (request()->file('img')->isValid())
{
$imageName = $request->file('img')->getClientOriginalName();
$pathImg = $request->file('img')->storeAs('files', $imageName, 'public');
}}
Update::create([
'customer_name' => $order->customer_name,
'customer_email' => $order->email,
'project_name' => $order->project_name,
'project_new_name' => $request['project_name'],
'description' => $request['desc'],
'image' => $pathImg ?? '',
'image_desc' => $request['img_desc'],
'ficheiro' => $path ?? '',
]);
return back()->with('success','Obrigado! Entraremos em contacto consigo em breve!');
}
I have no idea how to check if all inputs are empty in the controller . I've already tried this below, but it doesn't work. It keeps sending the form anyway.
if(count($request->all()) < 0) {
return dd('request all input empty.');
}

You can do it this way.
if(empty(array_filter($request->all()))){
//All fields are empty.
}
