thinkphp _complex 复合查询 where多个子组实现

SELECT * FROM `user` WHERE (  `mobile` = '13824653465' OR `nickname` = 'evan' OR `openid` = '14545-fdes'  ) AND (  `bind_seller` = 'fdaflj24214'  OR `seller_type` = '1'  ) AND ( `reg_time` < 12324568  AND  `login_count` > 10  )

　　THINKPHP 数组where实现多个复合查询，例如上面的sql。查询官方手册，感觉无法实现。于是想到修改一下THINKPHP框架的DB类。

thinkphp 3.1 文件所在 ThinkPHPLibCoreDb.class.php

tthinkphp 3.2  ThinkPHPLibraryThinkDbDriver.class.php

修改这个方法

    protected function parseThinkWhere($key,$val) {
        $whereStr   = '';
        switch($key) {
            case '_string':
                // 字符串模式查询条件
                $whereStr = $val;
                break;
            case '_complex':
            case '_complex1': //增加多个case分支，支持多个符合 只查询
            case '_complex2':
            case '_complex3':
            case '_complex4':13                 // 复合查询条件
                $whereStr = substr($this->parseWhere($val),6);
                break;
            case '_query':
                // 字符串模式查询条件
                parse_str($val,$where);
                if(isset($where['_logic'])) {
                    $op   =  ' '.strtoupper($where['_logic']).' ';
                    unset($where['_logic']);
                }else{
                    $op   =  ' AND ';
                }
                $array   =  array();
                foreach ($where as $field=>$data)
                    $array[] = $this->parseKey($field).' = '.$this->parseValue($data);
                $whereStr   = implode($op,$array);
                break;
        }
        return $whereStr;
    }

 $      where['mobile'] = '13824653465';
        $where['_logic']  = 'or';
        $where['nickname'] = 'evan';
        $where['openid']  = '14545-fdes';



        $where2['bind_seller'] = 'fdaflj24214';
        $where2['seller_type'] = '1';
        $where2['_logic']      = 'or';

        $where3['reg_time']    = array('lt',12324568);
        $where3['login_count'] = array('gt',10);

        $map['_complex'] = $where;
        $map['_complex1']= $where2;
        $map['_complex2']= $where3;

        $sql = M('User')->where($map)->select();
        echo M()->getLastSql();
