laravel表单文本，带有值扩展

Question

I have a form where there's a field that is disabled and contains a dynamic value gathered from a class function, code looks like this:

{!! Form::input('number', 'estimate', Estimate::getTotal($userId), ['class' => 'form-control', 'disabled']) !!}

Now what I want to accomplish is to add a static currency string, like 'USD', after it. So the textfield would contain "5000 USD", instead of the just the number. How can I do that?

Oh and the function looks like this:

public static function getTotal($userId)
{
    $estimates = self::whereNull('case_id')->where('user_id', '=', $userId)->get();
    $total = 0;

    foreach ($estimates as $estimate){
        $rate = Competence::where('id', $estimate->competence_id)->first()->hourely_rate;
        $total = $total + $estimate->hours * $rate;
    }

    return $total;
}

Answer 1

You're using an number input type, pretty self explaining that this input can't contain a string. Change the type to text and simply use:

Estimate::getTotal($userId) . ' USD'

You could also edit your function to return the total amount plus the currency.
