Question

我正在建立一个网站，以便用户可以在网站上添加产品。现在我正在处理产品详细信息页面。一切正常，产品的所有细节都得到了回应。但是现在我正在尝试创建一个按钮，当您单击该按钮时，它必须链接到我命名为“cadeaupagina_ontvanger”的新视图页面，并且还必须复制产品并将其粘贴到该视图页面上。我不知道如何在CodeIgniter中编写这个函数，有人能帮助我吗？

这是详细信息页面中的按钮：

<a href="<?php echo base_url() . 'Product/cadeaupagina_ontvangen/'.$product['user_id'];?>"> <button type="button" class="btn btn-default">Ik wil dit cadeau!</button></a>

控制器功能详情：

 public function details($product_id)
  {
    //load the Product_model
    $this->load->model('Product_model');
    //call function getdata in de Product_model
    $data['userdetail_list'] = $this->Product_model->getdata();
    $this->session->set_userdata("product_id", $product_id);

    //get product details
    $data['product'] = $this->Product_model->get_product_details($product_id);
    $data['products'] = $this->Product_model->selectProducts();

    //laad view
    $data['main_content'] = 'details';
    $this->load->view('details',$data); 
  }

控制器功能cadeaupagina_ontvangen：

 public function cadeaupagina_ontvangen($product_id) {
    $this->load->model('Product_model');
    //call function getdata in de Product_model
    $data['userdetail_list'] = $this->Product_model->getdata();

    // get product details
    // if you want to pass data by url last param than use this
    if(!empty($product_id)){
    $data['product'] = $this->Product_model->get_product_details($product_id);
     }


    //if you want to pass data in session than use this
    //get session in current controller
    $product_id = $this->session->userdata("product_id");
    if(!empty($product_id)){
      $data['product'] = $this->Product_model->get_product_details($product_id);
    }


    $data['products'] = $this->Product_model->selectProducts();

    //laad view
    $data['main_content'] = 'ontvangen_cadeaus';
    $this->load->view('cadeaupagina_ontvanger',$data);
  }

cadeaupagina_ontvanger是我要粘贴相同产品的视图页面。

Product_model中的模型函数：

 public function getdata()
    {
        $this->db->select('*');
        $this->db->from('users');
        $this->db->join('products','products.user_id = users.user_id');
        $query = $this->db->get();
        if($query->num_rows()>0)
        {
           return $query->result_array();
        }
    }

    public function selectProducts()
    {
        $query= $this->db->query("SELECT * FROM products");
        $result = $query->result_array();
        return $result;
    }



     /** Met deze functie kan je de product details ophalen via de $product_id  **/
    public function get_product_details($product_id) 
    {
        $arrReturn = array();
        $this->db->select('*');
        $this->db->from('products');
        $this->db->where('product_id', $product_id);
        $query = $this->db->get();
        $result = $query->result_array();
        if (!empty($result)) {
            $arrReturn = $result[0];
        }
        return $arrReturn;
    }

Answer 1

您可以通过以下两种方式执行此操作：

<强> 1。使用控制器URL发送产品ID。请确保在此网址中添加最后一个产品ID。

<a href ='<?php echo base_url("Product/cadeaupagina_ontvangen/$product_id"); ?>'><button type="button" class="btn btn-default">Ik wil dit cadeau!</button></a>

<强> 2。或者您可以在会话中添加产品ID以及此前的控制器

$this->session->set_userdata("product_id", $whatever_product_id);

现在在当前的控制器中：

public function cadeaupagina_ontvangen($product_id='') {
    $this->load->model('Product_model');
    //call function getdata in de Product_model
    $data['userdetail_list'] = $this->Product_model->getdata();

    //get product details
    //if you want to pass data by url last param than use this
    if(!empty($product_id)){
      $data['product'] = $this->Product_model->get_product_details($product_id);
    }


    //if you want to pass data in session than use this
    //get session in current controller
    $pid = $this->session->userdata("product_id");
    if(!empty($pid)){
      $data['product'] = $this->Product_model->get_product_details($pid);
    }




    //laad view
    $data['main_content'] = 'ontvangen_cadeaus';
    $this->load->view('cadeaupagina_ontvanger',$data);
}

将产品复制到CodeIgniter中的另一个视图页面
