Question

我正在尝试更新数据库中的记录，但由于某种原因它没有更新。也许我传递ID的方式有问题？

模特：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class site_model extends CI_Model {




    function __construct()
    {
        // Call the Model constructor
        parent::__construct();

    }


     function get_records()
    {
        $query = $this->db->get('posts');

        return $query->result();

    }


    function get_records_by_id()

    {
        $this->db->where('postID', $this->uri->segment(3));
        $query = $this->db->get('posts');

        return $query->result();

    }


    function add_records($data) {

        $this->db->insert('posts', $data);

        return;


    }

    function updata_records($data) {

        $this->db->where('postID', $this->uri->segment(3));
        $this->db->update('posts', $data);



    }

    function delede_roe() {

        $this->db->where('postID', $this->uri->segment(3));
        $this->db->delete('posts');



    }

}

Answer 1

updata_records（$ data），我认为问题在于，模型函数应该有$ data数组的uri数据。

$data = array (
'postID' => $this->uri->segment(3),
'post_content' => $post_content 
);

$this->site_model->updata_records($data);

通过uri在codeigniter中更新db
