在TP3中想要or查询

条件可以为：

$condition['grade'] = 1;

$condition['class'] = 3;

$condition['sex'] = 2;

$condtion['_logic'] = 'OR';

$list = M(‘user’)->where($condtion)->findall();

然后在TP5中尝试用where去这么查询发现一直在报错，查了手册之后发现TP5取消了_logic作为查询方式，而是新增了whereOr方法，下面是TP5中查询方式

User.php

namespace app\index\controller;

use app\index\model\UserModel;

class User

{

public function index()

{

$condition['grade'] = 1;

$condition['class'] = 3;

$condition['sex'] = 2;

$UserModel = new UserModel;

$list = $UserModel->getlistwhereOr($condition);

print_r($list);

}

}

UserModel.php

namespace app\index\model;

use app\common\model\CommonModel;

use think\Db;

use think\Model;

class UserModel extends CommonModel

{

public function __construct(){

parent::__construct();

}

protected $name = 'User';

public function getlistwhereOr($condition) {

$list =Db::name($this->name)->whereOr($condition)->select();

return $list;

}

}

执行User.php 发现打印出来的数据就是我们要的筛选数据，

总结：TP5相比TP3中更新了很多我们经常用到的查询方式，而且写法更人性化，需要经常的去整理查看这些新方法

或者也可以用$where['custom_name|custom_phone'] = ['like', "%" . $post['keyword'] . '%'];这种方法或查询，如输入关键词模糊查找几个字段如下代码：

$where['land_no'] = 0;

if ($post['keyword']) {

$where['custom_name|custom_phone'] = ['like', "%" . $post['keyword'] . '%'];

}

$where['custom_id'] = 0;

$num = db('land')->where($where)->select();

３.采用闭包方式

tp5中采用闭包的方式：

$map['user_id']=1;

$map['status']=0;

$or_map['user_id']=$map['user_id'];

$or_map['audit']=['in',['1,2']];

$list = Db::name('table')->where(function ($query) use ($map){

$query->where($map);

})->whereOr(function ($query) use ($or_map){

$query->where($or_map);

})->select();

//生成的sql语句：

//SELECT * FROM `tp_table` WHERE  (  `user_id` = '1'  AND `status` = 0 ) OR (  `user_id` = '1'  AND `audit` IN ('1,2') )

４.普通方式

$where = [

'feed_uid' => [ 'eq' , 5] ,

'status' => [ [ 'eq' , 1] , [ 'eq' , 2 ] , [ 'eq' , 3 ] , 'or' ] ,

];

$value = DealSpace::where($where)->count();

//最终的查询条件为where feed_uid=5 and (status=1 or status =2 or status =3 )
