Question

如何设置图标的不同状态？我想让它在喜欢/不喜欢的图标之间切换。我能这样做吗？我不完全理解语法。 btn-success类用于喜欢的图标，而btn-danger用于unliked按钮。

        @if(Auth::check())
        @if( !$unblock )
        <span data-id="{{ $key->id }}" data-like="Like" data-like-active="Remove Like" title="@if(!empty($likeUser)) Remove Like @else Like @endif" class="btn btn-xs pull-left @if(!empty($likeUser)) btn-success @else btn-danger @endif btn-like likeButton @if(!empty($likeUser)) active @endif">
            <i class="Like-icon"></i>
        </span>
        @else

Answer 1

你在@else

之后几乎完成了这个条件

Here是了解有关刀片和模板的更多信息的地方

就像普通的PHP if..else条件

一样简单

@if (Auth::check())
Authorized
@else
Nope
@endif

如果你想在其中有其他条件

@if (Auth::check())
Authorized
//your additional conditions for authorized users
@else
Nope
@endif

Answer 2

@if (count($records) === 1)
  I have one record!
@elseif (count($records) > 1)
  I have multiple records!
@else
  I don't have any records!
@endif

Laravel if / else语法
