我在删除按钮中添加了以下if语句：
@if(Auth::user() == $status->user)
<button type="submit" class="btn btn-danger">
<a href="{{ route('user.status.delete',['status_id'=>$status->id]) }}">Delete</a>
@endif
它应该隐藏其他帖子的按钮，只显示在您的帖子中，但它也隐藏在您自己的帖子中。

使用此代码。它会起作用。
SELECT `user_id`,
GROUP_CONCAT(CASE WHEN `field_id` = 'field_2' THEN `field_value` ELSE NULL END) AS field_2,
GROUP_CONCAT(CASE WHEN `field_id` = 'field_3' THEN `field_value` ELSE NULL END) AS field_3
FROM `my_table`
GROUP BY `user_id`
having sum(field_id = 'field_1' and field_value = 'Summer') > 0;
我认为您只想向帖子的所有者显示删除按钮。在这种情况下，如果@if(Auth::id() == $status->user->id)
// Show Delete button
@endif
模型位于user变量中，此代码将有效。

尝试下面给出的代码，如果它不适合你，请告诉我：
@if(Auth::id() == $status->user_id)
<button type="submit" class="btn btn-danger">
<a href="{{ route('user.status.delete',['status_id'=>$status->id]) }}">Delete</a>
</button>
@endif
