Question

我正在使用下面的功能向购物车添加一个项目（现在是一个数组，稍后将存储在会话中）。一切正常，唯一的问题是，当我单击“ 添加+ ”按钮时，它会将所有值存储在数组中，但之后会显示空白页。

我的控制器

if($action == 'Add+') {
    if($this->session->userdata('cart')== ''){
        $image=$this->input->post('hidden_image');
        $name= $this->input->post('hidden_name');
        $price= $this->input->post('hidden_price');
        $cat= $this->input->post('hidden_cat');
        $id= $this->input->post('hidden_id');
        $product = array("name"=>$name, "price"=>$price, "id"=>$id, "image" => $image,"cat"=>$cat);
        $item= array("0"=>$product);
        $this->session->set_userdata('cart',$item);

    }
    else{
        $count= count($this->session->userdata('cart'));
        $name= $this->input->post('hidden_name');
        $price= $this->input->post('hidden_price');
        $id= $this->input->post('hidden_id');
        $image=$this->input->post('hidden_image');
        $cat= $this->input->post('hidden_cat');
        $product = array("name"=>$name, "price"=>$price, "id"=>$id, "image" => $image,"cat"=>$cat);
        $item= array($count=>$product);
        $data = $this->session->userdata('cart');
        $_SESSION["cart"][$count] = $product;
    }
}
if($action == 'View') {
    $image=$this->input->post('hidden_image');
    $name= $this->input->post('hidden_name');
    $price= $this->input->post('hidden_price');
    $id= $this->input->post('hidden_id');
    $cat= $this->input->post('hidden_cat');
    $product = array("name"=>$name, "price"=>$price, "id"=>$id, "image" => $image,"cat"=>$cat);
    $this->load->view('product_head');
    $this->load->view('header',$product);
    $this->load->view('product',$product);
}

我的视图

 <?php $data= array ('id'=>'productform');
                     echo form_open_multipart('loader/product',$data);
                                $data = array(
                                'type'          => 'hidden',
                                'name'          => 'hidden_cat',
                                'value' => $row->category);
                                $val = set_value('hidden_cat');
                                echo form_input($data, $val);


                                $data = array(
                                'type'          => 'hidden',
                                'name'          => 'hidden_name',
                                'value' => $row->name
                                    );
                                $val = set_value('hidden_name');
                                echo form_input($data, $val);


                                $data = array(
                                    'type'          => 'hidden',
                                    'name'          => 'hidden_image',
                                    'value' => $row->image
                                        );
                                    $val = set_value('hidden_image');
                                    echo form_input($data, $val);


                                $data = array(
                                    'type'          => 'hidden',
                                    'name'          => 'hidden_id',
                                    'value' => $row->id
                                        );
                                    $val = set_value('hidden_id');
                                    echo form_input($data, $val);


                                $data = array(
                                'type'          => 'hidden',
                                'name'          => 'hidden_price',
                                'value' => $row->price
                                    );
                                $val = set_value('hidden_price');
                                echo form_input($data, $val);


                                $data = array(
                                'name' => 'action',
                                'style'         => ' background-color: #4CAF50; border: none;',
                                'value'      => 'View'
                                 );
                                echo form_submit($data);    


                                $data = array(
                                'name' => 'action',
                                'style'         => ' background-color: #4CAF50; border: none;',
                                'id' => 'addbtn'
                                    );
                                echo form_submit($data);

                                echo form_close(); 
                                ?>

我想要的是，在成功提交表单之后，它将保留在同一页面上的同一位置，因为对于许多产品而言，有很多页面都具有这些隐藏的表单。

您需要添加重定向

/**
 * This function is used to add new user to the system
 */
function addNewUser()
{
    if($this->isAdmin() == TRUE)
    {
        $this->loadThis();
    }
    else
    {

        $this->form_validation->set_rules('fname','Full Name','trim|required|max_length[128]');
        $this->form_validation->set_rules('email','Email','trim|required|valid_email|max_length[128]');
        $this->form_validation->set_rules('password','Password','required|max_length[20]');
        $this->form_validation->set_rules('cpassword','Confirm Password','trim|required|matches[password]|max_length[20]');
        $this->form_validation->set_rules('role','Role','trim|required|numeric');
        $this->form_validation->set_rules('mobile','Mobile Number','required|min_length[10]');

        if($this->form_validation->run() == FALSE)
        {
            $this->addNew();
        }
        else
        {
            $name = ucwords(strtolower($this->security->xss_clean($this->input->post('fname'))));
            $email = strtolower($this->security->xss_clean($this->input->post('email')));
            $password = $this->input->post('password');
            $roleId = $this->input->post('role');
            $mobile = $this->security->xss_clean($this->input->post('mobile'));

            $userInfo = array('email'=>$email, 'password'=>getHashedPassword($password), 'roleId'=>$roleId, 'name'=> $name,
                                'mobile'=>$mobile, 'createdBy'=>$this->vendorId, 'createdDtm'=>date('Y-m-d H:i:s'));
    echo print($name);

                echo '<pre>';print_r($userInfo);
                exit();
            $this->load->model('user_model');
            $result = $this->user_model->addNewUser($userInfo);

            if($result > 0)
            {
                $this->session->set_flashdata('success', 'New User created successfully');
            }
            else
            {
                $this->session->set_flashdata('error', 'User creation failed');
            }

            redirect('addNew');
        }
    }
}

按照此示例redirect（'addNew'）;

成功提交表单后为空白页-Codeigniter
