if div class is empty (using laravel foreachloop)

Question

Here I have a foreach loop of teachers with their associated relationships which are reviews. As I loop through the teacher if they have no relationship or review I want to print "No Reviews" in the containing div. The code i use now works, however if one teacher has a review the other classes remain empty instead of saying No Review. Is there a way in laravel or in js i can do this? It's probably a simple solution for this. Can someone help me out?

HTML:

 @foreach($teachers as $teacher)
      <div class="item{{{ $isFirst ? ' active' : '' }}}">
          <div class = "deck">
               <div class = "row marg">
                    <div class="col-md-8">
                         <div class = "stdnt">
                              <h1>Teacher Info</h1>
                              {!! Form::model( $student, ['url' => ['tchUpd', $teacher->id], 'method' => 'post', 'role' => 'form'] ) !!}
                               <h1>{{ucwords($teacher->name)}}</h1>
                                <div class = "form-group fga">

                                                    </div>

JS

if ( $('.reviewblock').children().length == 0 ) {
    $(this).append("<div class = 'empty'><h1>No Reviews</h1></div>");
}

/--------------second attempt ---------/

if (isEmpty($('.reviewblock'))) {
        $('.reviewblock').append("<div class = 'empty'><h1>No Reviews</h1></div>");
    }

Your code will do it only for the first occurrence of the class ".reviewBlock". Do it for all the occurrences.

$('.reviewblock').each(function(i, obj) {
    if (isEmpty(this))) {
        $('.reviewblock').append("<div class = 'empty'><h1>No Reviews</h1></div>");
    }
});

He just asked laravel or js. I just gave my opinion on JS since you've done it in laravel.

All you have to do is chekc if the variable is empty

<div class = "row-fluid marg reviewblock">
@if (empty($teacher->reviews))
    <div class = 'empty'><h1>No Reviews</h1></div>
@else
    @foreach($teacher->reviews as $review)
    <div class = "ablock">
        <h1>{{ucwords($review->title)}}</h1>
        <p>{{$review->created_at}}</p>
        <p>{{$review->title}}</p>
        <p>{!!$review->description!!}</p>
    </div>
    @endforeach
@endif
</div>

NOTE: Ah I forgot, remove all of the JS that you use to append HTML, you don't need that. Also would advise you not to use <H1> tag to style you page, this should be used only once on each page and that normally goes to the title/header of the page, otherwise Google might penalise you.

Still not printing anything? Maybe switch the if and the else statements?
