How to keep data already filled in the textarea and select option after submitting a form?

Question

I am using the PHP language and the Laravel Framework 5. In the form validation, if it contains any blank field or with unaccepted character sizes, clicking save shows the validation message, but the fields of the textarea and select option that were filled are empty. How to keep these types of data in the form after clicking save when some field is incorrect?

Textarea code:

    <textarea class="form-control" name="descricao" id="descricao"></textarea>

My select only has one option because it takes the values directly from the database. Select option code:

    <select class="form-control" name="categoria" id="categoria">           
        <option value="null"> Selecione uma categoria </option>
            @foreach($categorias as $row)
                <option value="{{ $row->id }}"
                    {{ $row->nome }}
                </option>
            @endforeach
    </select>

You must use the function old. She is responsible for bringing back data from the previous disappearance stored in a Session Flash.

So you can just do it like this:

 <input type="text" name="nome" value="{{ old('name') }} />
 <textarea name="texto">{{ old('texto') }}</textarea>

However, I suggest you install the Laravel Collective Htmlbuilder library. This will make it easier to create inputs, textareas or selects.

Example:

{!! 
    Form::select('item_id', $itens, old('item_id'), ['class' => 'form-control']) 
!!}

{!!
   Form::textarea('texto', old('texto'))
!!}
