2 查询发生错误

Question

处理此表单时，会生成 2 个查询。

在查询1中：所有数据都成功，但图片除外。图片：听起来值“NULL”。

查询2：图片书写正确。但其他数据正在写入“NULL”。

我想要的是，不是查询 2，而是查询 2 中的图像数据应该来到查询 1，并且应该只形成 1 个查询。

这是我的控制器和模型

public function send_Basvur_message(){

$this->load->library("form_validation");
$this->load->model("Basvur_model");

$this->form_validation->set_rules("name", "Ad", "trim|required");
$this->form_validation->set_rules("email", "E-posta", "trim|required|valid_email");
$this->form_validation->set_rules("subject", "Konu", "trim|required");
$this->form_validation->set_rules("message", "Mesaj", "trim|required");
$this->form_validation->set_rules("url", "url");
$this->form_validation->set_rules("captcha", "Doğrulama Kodu", "trim|required");

$path = './panel/uploads/basvur_v/';
$initialize = $this->upload->initialize(array(
    "upload_path" => $path,
    "allowed_types" => "gif|jpg|jpeg|png|bmp",
    "remove_spaces" => TRUE
));
$imagename = 'no-img.jpg';
$config['max_size'] = 51200;
$config['overwrite'] = false;
$config['encrypt_name'] = false;
$config['remove_space'] = false;
$imagename = 'no-img.jpg';


if($this->form_validation->run() === FALSE){
} else if(!$this->upload->do_upload('img_url')) {
    $this->session->set_flashdata('info','Action Completed');
    redirect(base_url("basvuru"));
} else {

    $insert = $this->Basvur_model->add(
        array(
            "name"          => $this->input->post("name"),
            "email"         => $this->input->post("email"),
            "message"       => $this->input->post("message"),
            "subject"       => $this->input->post("subject"),
            "url"           => $imagename,
            "created_at"    => date("Y-m-d H:i:s")
        )
    );
    $data = $this->upload->data();
    $imagename = $data['file_name'];
    $this->Basvur_model->setURL($imagename);            
    $this->Basvur_model->create();                           
    $this->session->set_flashdata('img_uploaded', $imagename);

    if($this->session->userdata("captcha") == $this->input->post("captcha")){

        $name = $this->input->post("name");
        $email = $this->input->post("email");
        $subject = $this->input->post("subject");
        $message = $this->input->post("message");


        $email_message = "{$name} isimli ziyaretçi. Başvuru Yaptı <br><b>Mesaj : </b> {$message} <br> <b>E-posta : </b> {$email}";

        if(send_email("", "Yeni Aday başvurusu | $subject", $email_message)){
            $this->session->set_flashdata('success','Action Completed');
            redirect(base_url("basvuru"));
            // TODO Alert..
        } else {
            $this->session->set_flashdata('success','Action Completed');
            redirect(base_url("basvuru"));
            // TODO Alert..
        }

    } else {
        //başarısıs
    $this->session->set_flashdata('error','Action Not Completed');
    redirect(base_url("basvuru"));

    }
}
}

型号

    <?php

class Basvur_model extends CI_Model

    public $tableName = "basvurs";

    public function __construct()
    {
        parent::__construct();

    }

        private $_ID;
    private $_url;

    public function setID($ID) {
        $this->_ID = $ID;
    }

    public function setURL($url) {
        $this->_url = $url;

    public function getPicture() {        
        $this->db->select(array('p.id', 'p.url'));
        $this->db->from('basvurs p');  
        $this->db->where('p.id', $this->_ID);     
        $query = $this->db->get();
       return $query->row_array();
    }
    // insert image

        );

        return $this->db->insert_id();
    }

    

    public function get($where = array())
    {
        return $this->db->where($where)->get($this->tableName)->row();
    }

    /** Tüm Kayıtları bana getirecek olan metot.. */
    public function get_all($where = array(), $order = "id ASC")
    {
        return $this->db->where($where)->order_by($order)->get($this->tableName)->result();
    }

    public function add($data = array())

    public function update($where = array(), $data = array())

    public function delete($where = array())

    }

}

Answer 1

关于代码中的查询 1，您会注意到：

$data = $this->upload->data();
$imagename = $data['file_name'];

直到插入 $insert 语句之后才会填充。把它移到前面。

关于您的第二个查询，我不确定填充为 NULL 的内容，但是您发送给查询的唯一变量是 url。

 public function create() { 
        $data = array(
            'url' => $this->_url,
        ); // see just this^
        $this->db->insert('basvurs', $data);
        return $this->db->insert_id();
    }

现在所有这些数据似乎都进入了同一张表？我不确定你为什么不只在一个插入语句中完成所有操作。为什么要重复条目也有点令人困惑。
