带条件的代码点火器输入数据库

问题描述

我是codeigniter的新手，我想在使用输入添加一些数据时遇到问题。在我的情况下，它将在第一页上从用户数据库获取显示交货信息为默认值的数据，可以编辑此输入，如果我单击提交，它将保存在交货数据库上。我单击提交数据时的第一个问题，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，如果选中复选框，输入的数据将默认保存到用户数据库，并将保存到交货数据库。

此我的模型（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);
}

此我的控制器（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');
    }
}

这是我的观点（交付）：

这是我的投放数据库：delivery 这是我的用户数据库：user

交付视图delivery.php的这张图片

对不起，我的英语不好。请帮我。我感谢每个答案。

解决方法

INSERT语句不应包含WHERE子句。 where子句将永远不会满足，因此将永远不会插入。

在更新或替换记录时，where子句很有意义（因为它会缩小实际上最终更新的现有记录的范围）

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

仅在复选框打钩时才插入，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');
}
