Add class to input field if the field has a value

Question

Thanks in advance!

Please could someone help me I need to add a class ".filled" to the input field below if the value field isn't null?

<input name="total_price" class="form-control" id="ProposalPriceTotal" type="text" value="{{ $proposal->total_price }}">

You can easily do that with PHP ternary operator. You can Google it later for explanation. It just a simple code:

<input name="total_price" class="form-control {{ $proposal->total_price 
== null ? '' : 'filled' }}" id="ProposalPriceTotal" type="text" value=" 
{{ $proposal->total_price }}">

Surely, the comparison value is depend on your type of data. But I think that using null should be fine.
