发生这种情况是因为您放错了'
,您应该正确地传递值作为回报
为此替换您的编辑方法:
public function edit($id)
{
$category = Category::find($id);
return view('admin.categories.edit', ['category' => $category]);
}

发布代码时,请尝试使其尽可能可读。实现此目的最简单的方法是在发布整个帖子之前先阅读一下。
关于这个问题:
在CategoriesController@edit
区域中
['category=>$category']
与
['category'=>$category]
在这种情况下,您也可以使用
compact('category')
变量$category
与数组'category'
的键名相同,而不是数组。

这很简单!
只需替换您的编辑功能
return view('admin.categories.edit', ['category=>$category']);
具有:
return view('admin.categories.edit')->withCategory($category);
