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 \ThinkPHP\Lib\Core\Db.class.php

tthinkphp 3.2  \ThinkPHP\Library\Think\Db\Driver.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':                 // 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();
