mysql - 如何在 codeigniter 模型中获取最近受影响的行属性

Question

title表的主键是id，当我向表中插入数据时，它是一个自增我需要返回id 当前插入的行。

我的模型函数是，

    function addDate($x, $y, $z) {
        $sql = "INSERT INTO title (title,no,user) VALUES ('$x','$y','$z')";
        $query = $this->db->query($sql );
        if($this->db->affected_rows() > 0) {
            return "ok";
        } else {
            return "err";
        }
    }

请帮我解决这个问题。

Answer 1

You are wrong. In your function you are getting these three parameters ($x, $y, $z) But in code you are Inserting ('$t','$n','$a')(Question is edited)

使用$this->db->insert_id()获取最后插入的id

试试这个

function addDate($x, $y, $z) {

    $data = array(
       'title'  => $x ,
       'no'     => $y ,
       'user'   => $z
    );

    if(!$this->db->insert('title', $data)){
        return FALSE ;
    }
    else{
        $lastId =  $this->db->insert_id(); # add this
        return $lastId; 
    }
}

FYI: Don't use $x, $y, $z. use meaningful names like $title, $no, $user
