删除控制器方法
这里可以删除一个也可以同时删除多个，所以传递过来的友链id是一个数组形式的
// 删除友链 public function link_del(){ $data = Request::post(); $link_id = []; foreach ($data['link'] as $key => $value) { $link_id[] = $value['link_id']; } $res = Db::table('friend_link')->delete($link_id); if($res){ exit(json_encode(['code'=>0,'msg'=>'删除成功'])); }else{ exit(json_encode(['code'=>1,'msg'=>'删除失败，请重试……'])); } }
网站基础设置效果
后端采用thinkphp6.0，首先是网站基础设置，网站基础在数据库中可以建立一个单独的表，但是这个单独的表存放的信息很特殊，表里可以存商品规格，或者别的数据，因为这个网站设置就是设置网站的tdk，表字段的名称是这样的，names，values，就只有这两个字段，names的字段可以存tdk，或者商品名称，第二个values，可以存放tdk的信息，还有商品规格信息，我们将这些数据转换成json存入表中，需要的时候再json_decode取出渲染到前端页面。
这种存储方式和商品的SUK很相似，因为同一个商品，很能有很多规格，我们不可能给每个商品在创建一个对应的规格表，这里的网站设置也是，我们如果给例如网站名称关键字描述备案号创建一个表的话，那么网站的轮播图也要单独创建一个表，后续接入第三方接口有一些配置参数，我们又要新建一个表来存储，这样过于浪费，里面新建了几个字段，可能就一行记录。
我们采用JSON形式存储到记录中，将对象转换为JSON字符串存储到一条记录中，起一个name名称。对象的描述能力是很强的，我们将需要存储的信息放到对象中，然后转换为json字符串放到表中，下一次取出来json字符串在将其转换为对象。这样就可以一张表存储很多数据配置了，我们将文章设置的一些信息存储为name叫tdk，vals为对应的配置信息json字符串。
控制器Setting.php
这里我们先查询name名叫tdk的记录是否存在，如果第一次设置配置信息，不存在该条记录则插入配置信息记录，如果查询到了该条配置信息，这更新网站配置信息。注意：我们接受的是一个对象，存储数据库的时候，要将其转换为json字符串才可以，存储渲染的时候也要转回数组对象。
