Php Codeigniter，其中或和来自会话的阵列

我在

会话->用户数据（'usershop'）

中有以下数组：

我必须从另一个表中选择数据：

只能从该表中选取

链码

和

商店码

匹配的行

我试过这个：

foreach ($this->session->userdata('usershop') as $usr => $usrshop) {
        $where = $this->db->where(array('chain_code' => $usrshop['shop_chain'], 'shop_code' => $usrshop['shop_code']));
    }
    return $this->db->get('wd2dbschema_config.cfg_shop')->result();

但所有这些都是取错行，结果是：

SELECT * FROM "wd2dbschema_config"."cfg_shop" WHERE "chain_code" = '9001' AND "shop_code" = '1' AND "chain_code" = '9002' AND "shop_code" = '1' AND "chain_code" = '9001' AND "shop_code" = '2' AND "chain_code" = '9001' AND "shop_code" = '3'

我如何做到这一点，使它只需要匹配的行

像这样：

SELECT * FROM "wd2dbschema_config"."cfg_shop" WHERE ("chain_code" = '9001' AND "shop_code" = '1') OR ("chain_code" = '9002' AND "shop_code" = '1') OR ("chain_code" = '9001' AND "shop_code" = '2') OR ("chain_code" = '9001' AND "shop_code" = '3')

试一试

foreach ($this->session->userdata('usershop') as $usr => $usrshop) {
    $where = $this->db->where(array('chain_code' => $usrshop['shop_chain'], 'shop_code' => $usrshop['shop_code']));
    $data[] = $this->db->get('wd2dbschema_config.cfg_shop')->result();
}
return $data;

您可以执行一次every where条件，并需要在数组中捕获它们，在循环完成后，您可以直接传递它。

使用活动记录您可以这样做，请确保将

where（）/中的第二个参数传递为null，以便活动记录不会查找第一个参数的比较，第三个参数为FALSE，因此活动记录不会向where子句表达式添加额外的标记

$i = 0;
foreach ($this->session->userdata('usershop') as $usr => $usrshop) {
    if($i==0){
        $this->db->where(" (chain_code = '" . $usrshop['shop_chain'] . "' AND shop_code = '" . $usrshop['shop_code'] . "') ", null, FALSE);
    }else{
        $this->db->or_where(" (chain_code = '" . $usrshop['shop_chain'] . "' AND shop_code = '" . $usrshop['shop_code'] . "') ", null, FALSE);
    }
    $i++;
}
return $this->db->get('wd2dbschema_config.cfg_shop')->result();

$i = 0;
