带条件的 Codeigniter 输入到数据库

Question

我是 codeigniter 的新手，当我想使用输入添加一些数据时遇到问题。在我的例子中，在第一页上，它将从用户数据库中获取默认显示交付信息的数据，可以编辑此输入，如果我单击提交，它将保存在交付数据库中。第一个问题，当我点击提交数据时，它无法保存到数据库。如何解决这个问题？第二种情况，我想给出一些条件，如果复选框勾选，输入的数据将默认保存到用户数据库，并将保存到交付数据库。

这个我的模型(M_checkout) :

public function get_user_by_id($customer_id)
{
    $data = $this->db->select('*')
        ->from('user')
        ->where('user_id', $customer_id)
        ->get()
        ->row();
    return $data;
}
public function add_delivery()
{
    $data = array();
    $customer_id = $this->input->post('user_id');
    $this->db->where('user_id', $customer_id);
    $data['user_id'] = $customer_id;
    $data['user_nama'] = $this->input->post('user_nama');
    $data['user_email'] = $this->input->post('user_email');
    $data['user_phone'] = $this->input->post('user_phone');
    $data['user_wa'] = $this->input->post('user_wa');
    $data['user_alamat'] = $this->input->post('user_alamat');
    $data['user_kota'] = $this->input->post('user_kota');
    $data['user_provinsi'] = $this->input->post('user_provinsi');
    $data['user_zip'] = $this->input->post('user_zip');
    $this->db->insert('delivery', $data);
    $customer_deliv_id = $this->db->insert_id();
    $sdata = array();
    $sdata['delivery_id'] = $customer_deliv_id;
    $this->session->set_userdata($sdata);
}

这个我的控制器（结帐）：

 public function add_delivery_to_db()
{
    $this->form_validation->set_rules('user_nama', 'Nama', 'trim|required');
    $this->form_validation->set_rules('user_email', 'Email', 'trim|required');
    $this->form_validation->set_rules('user_phone', 'Nomer Telpon', 'trim|required|min_length[10]|max_length[12]');
    $this->form_validation->set_rules('user_wa', 'Nomer WA', 'trim|required|min_length[10]|max_length[12]');
    $this->form_validation->set_rules('user_alamat', 'Nomer Alamat', 'trim|required');
    $this->form_validation->set_rules('user_kota', 'Nomer Kota', 'trim|required');
    $this->form_validation->set_rules('user_provinsi', 'Nomer Provinsi', 'trim|required');
    $this->form_validation->set_rules('user_zip', 'Nomer Zip', 'trim|required|min_length[5]|max_length[5]');

    if ($this->form_validation->run()) {
        $delivery_post_id = $this->M_checkout->add_delivery(); 

        redirect('payment', 'refresh');
    } else {

        redirect('delivery', 'refresh');
    }
}

这是我的看法（交付）：

    </p>
    <div class="column is-3"></div>
    <div class="column is-6 has-addons-fullwidth">

这是我的投递数据库：delivery 这是我的用户数据库：user

抱歉我的英语不好。请帮我。我感谢每一个答案。

Answer 1

INSERT 语句不应包含 WHERE 子句。 where 子句永远不会满足，因此永远不会进行插入。

where 子句在更新或替换记录时有意义（因为它会缩小您实际最终更新的现有记录的范围）

从您的 add_delivery 方法中删除 $this->db->where('user_id', $customer_id); 语句，插入将起作用。

关于仅在勾选复选框时才插入，有很多选择。最简单的是：

if ($this->form_validation->run()) {
    if ($this->input->post('delivery_checkbox') === 'on')
    {
       // only do the insert if the checkbox is actually ticked
       $delivery_post_id = $this->M_checkout->add_delivery();
    }


    redirect('payment', 'refresh');
}
