I'm using Laravel and Blade on a small project and am trying to dynamically assign class names to generated elements in a for loop. However, the generated elements are generating literally, such as "<div class='form_q' .$i>".

@for($i = 0; $i < count($formdata['form2']); $i++)
  <div class='form_q'.$i>
    HTML::attributes('class')
    <div class='q'.$i.'-header'>
      <h1>{{ Form::label($formdata['form2']['q'.($i + 1)]['question'], $formdata['form2']['q'.($i + 1)]['type'], array('class' => 'btn btn-primary'))}}</h1>
    </div>
  </div>
@endfor

What's the proper syntax for concatenating a string and variable and assigning it to an class/attribute? Alternatively, what is the proper Blade syntax for generating a "div" element with an assigned class?

You need to tell Blade or PHP you want to print the output.

Ether surround the $i variables like {{ $i }} or like <?php echo $i ?>. Blade just converts back to PHP for example, {{ }} is converted into <?php echo ?>. Keep in mind that you're still using PHP when making Blade templates.

@for($i = 0; $i < count($formdata['form2']); $i++)
  <div class='form_q{{ $i }}'>
      HTML::attributes('class')
      <div class='q{{ $i }}-header'>
        <h1>{{ Form::label($formdata['form2']['q'.($i + 1)]['question'], $formdata['form2']['q'.($i + 1)]['type'], array('class' => 'btn btn-primary'))}}</h1>
      </div>
  </div>
@endfor

You should go over the Blade docs again. http://laravel.com/docs/templates

I don't know laravel or blade, but I think you should use double curly brackets to echo a php variable, like this:

<div class='form_q'{{$i}}>
