I want to validate a field type file that is not required, but only if a file has been selected validate the type and size
This is on my controller:
if($request->hasFile('File')){
$file = $request->file('File');
$name = date_format($date,'Y-m-d').'_'.explode(' ',$emp->LastName)[0].'_'.explode(' ', $emp->Name)[0].'_'. $file->getClientOriginalName();
$path = Storage::putFileAs('test_img', $file, $name);
}else{
$path = null;
}
I propose to create a FormRequest for the respective validations, with the command
// reemplazar Model por el nombre del modelo el cuál validará
php artisan make:request ModelFormRequest
From this, generate the rules, where the most important would be a if simple within rules (method that generates the command, also for the moment return true in the authorize method)
public function rules()
{
$rules = [
'uncampo' => 'required',
'otrocampo' => 'required|min:5',
];
// Si el campo File se selecciono un archivo realizamos las validaciones
// respectivas como el tamaño y el tipo
if ( $this->hasFile('File') )
{
$rules['File'] = ['max:2000','mimes:pdf,docx,doc'];
}
return $rules;
}
You can add a validation with a Validator in your controller to validate the received file, you can specify what type of file or what size you need.
$file = $request->file('File');
$validator = Validator::make(
array(
'file' => $file,
),
array(
'file' => 'file|max:5000|mimes:pdf,docx,doc',
)
);
//Si no pasa la validacion realizas una accion
if ($validator->fails()) {
return Redirect::to('miruta');
}
I think you should simply add the nullable rule to your validation of the FILE field.
'file' => 'nullable|file|max:5000|mimes:pdf,docx,doc'
