Thinkphp框架对数据库的操作（总结）

$user = new User; $user->name = 'thinkphp'; $user->email = 'thinkphp@qq.com'; $user->save(); $user = new User; $user->save([ 'name' => 'thinkphp', 'email' => 'thinkphp@qq.com' ]);

$user = new User; // 过滤post数组中的非数据表字段数据 $user->allowField(true)->save($_POST);

$user = new User; // post数组中只有name和email字段会写入 $user->allowField(['name','email'])->save($_POST);

$user = new User; $list = [ ['name'=>'thinkphp','email'=>'thinkphp@qq.com'], ['name'=>'onethink','email'=>'onethink@qq.com'] ]; $user->saveAll($list);

$user = User::create([ 'name' => 'thinkphp', 'email' => 'thinkphp@qq.com' ]); echo $user->name; echo $user->email; echo $user->id; // 获取自增ID

$user = User::get(1); $user->name = 'thinkphp'; $user->email = 'thinkphp@qq.com'; $user->save();

$user = new User; // save方法第二个参数为更新条件 $user->save([ 'name' => 'thinkphp', 'email' => 'thinkphp@qq.com' ],['id' => 1]);

$user = new User; // 过滤post数组中的非数据表字段数据 $user->allowField(true)->save($_POST,['id' => 1]);

$user = new User(); // post数组中只有name和email字段会写入 $user->allowField(['name','email'])->save($_POST, ['id' => 1]);

$user = new User; $list = [ ['id'=>1, 'name'=>'thinkphp', 'email'=>'thinkphp@qq.com'], ['id'=>2, 'name'=>'onethink', 'email'=>'onethink@qq.com'] ]; $user->saveAll($list);

User::where('id', 1) ->update(['name' => 'thinkphp']);

// 实例化模型 $user = new User; // 显式指定更新数据操作 $user->isUpdate(true) ->save(['id' => 1, 'name' => 'thinkphp']);

$user = User::get(1); $user->name = 'thinkphp'; // 显式指定当前操作为新增操作 $user->isUpdate(false)->save();

$user = User::get(1); $user->delete();

User::destroy(1); // 支持批量删除多个数据 User::destroy('1,2,3'); // 或者 User::destroy([1,2,3]);

User::destroy(function($query){ $query->where('id','>',10); });

// 取出主键为1的数据 $user = User::get(1); echo $user->name; // 使用查询构造器查询满足条件的数据 $user = User::where('name', 'thinkphp')->find(); echo $user->name;

// 根据主键获取多个数据 $list = User::all('1,2,3'); // 或者使用数组 $list = User::all([1,2,3]); // 对数据集进行遍历操作 foreach($list as $key=>$user){ echo $user->name; }

// 使用查询构造器查询 $list = User::where('status', 1)->limit(3)->order('id', 'asc')->select(); foreach($list as $key=>$user){ echo $user->name; }

// 获取某个用户的积分 User::where('id',10)->value('score'); // 获取某个列的所有值 User::where('status',1)->column('name'); // 以id为索引 User::where('status',1)->column('name','id');
