@elseif(perPage=50)

@else
<a class="btn btn-default btn-sm ajax-link back-btn" href="invoice-list?perPage=10" type="button" >Back to List</a>
@endif

Answer 1

you can only write this line without any if:

<a class="btn btn-default btn-sm ajax-link back-btn" href="{{url('invoice-list?perPage=' . $perPage)}}" type="button">Back to List</a>

make sure that you have $perPage variable
