Codeigniter or_where_in [英] Codeigniter or_where_in

问题描述

我正在尝试在 Codeigniter 中组合这两个查询.因此，该行要么必须具有 $user 的 user_id，例如 3，要么必须具有与数组 $repost 匹配的 id.我知道怎么做 or_where 但你怎么做 or_where_in?

I am trying to combine these two queries in Codeigniter. So the row either has to have the user_id of $user eg 3 OR have an id matching the array $repost. I know how to do or_where but how do you do or_where_in?

谢谢

$this->db->where("user_id", "$user");
if (isset($conditions["repost"])) {

        $user_favourited = $conditions["repost"];

        $this->db->where("user_id", $user_favourited);
        $this->db->select("post_id");
        $this->db->from($this->repost_table);
        $query = $this->db->get();

        $id['posts'] = $query->result_array();

        foreach($id['posts'] as $post) {
            $repost[] = $post['post_id'];
        }

        if (isset($repost)) {
            $this->db->where_in('id', $repost);
        }
    }

推荐答案

$this->db->or_where_in();

语法:

or_where_in([$key = NULL[, $values = NULL[, $escape = NULL]]])

参数:

$key (string) – The field to search
$values (array) – The values searched on
$escape (bool) – Whether to escape values and identifiers

退货:

DB_query_builder instance

返回类型:

object

生成一个 WHERE 字段 IN(‘item’, ‘item’) SQL 查询，如果合适，加入‘OR’.

Generates a WHERE field IN(‘item’, ‘item’) SQL query, joined with ‘OR’ if appropriate.
