检查if语句中是否存在对象

Question

如何检查OR语句中是否存在属性，然后检查IF语句中是否设置了属性？

    @if($counsellingSession->has_session_begun == 1 || !empty($thread->close_session == 1))
         disabled
    @elseif($loop->index > 7 && $data->payment_type == 'free')
         disabled
    @endif

Answer 1

尝试property_exist php函数（如果存在）将为您提供true其他明智的false

property_exist($thread,'close_session')

了解property_exist

Answer 2

也许使用isset？它将检查对象是否存在或值为空

@if(isset($thread->close_session) && $thread->close_session == 1)
@endif

Answer 3

您可以使用property_exists吗？ 例如：

@if((property_exists($counsellingSession,"has_session_begun") && $counsellingSession->has_session_begun == 1) || (property_exists($thread,"close_session") && $thread->close_session == 1 ) )
         disabled
    @elseif($loop->index > 7 && $data->payment_type == 'free')
         disabled
    @endif
