I need to display tags on a page and the trick is that I do not want to show comma after the last tag.
So, I have this:
@foreach($tag as $t)
<a href="/search?q={{$t}}" class="tags">{{$loop->first ? '' : ', '}} {{$t}}</a>
@endforeach
And I want to have this:
A, B, C, D
But instead, I get this:
A , B , C , D
There is extra space between item and comma...
You need to check if the loop is on the last item or not, and if not, append a comma and a space (instead of prepending a comma and a space).
For example:
@foreach($tag as $t)
<a href="/search?q={{$t}}" class="tags">{{$t}}{{$loop->last ? '' : ', '}}</a>
@endforeach
The reason you were getting double spaces is because you were echoing out a space in PHP and also putting a space between your two curly braces.
Update: Although your answer would also work, it's a matter of preference. The original reason you had an extra space between the letter and comma was due to spacing between the curly brace variables.
