我想更新/編輯我的數據..data得到更新，但顯示

Question

它顯示了以下錯誤在PHP中的視圖頁面的一些錯誤：

1.Severity：警告

消息：缺少參數1個爲超級管理員:: edit_category（）

文件名：控制器/ super_admin.php

嚴重性：注意

消息：未定義變量：CATEGORY_ID

文件名：控制器/ super_admin.php

下面是型號的代碼：

<?php 

class Super_Admin_Model extends CI_Model 
{ 

    public function select_catgory_info_by_id($category_id) 
    { 
     $this->db->select('*'); 
     $this->db->from('tbl_category'); 
     $this->db->where('category_id', $category_id); 
     $query_result = $this->db->get(); 
     $result  = $query_result->row(); 
     return $result; 
    } 

    public function update_category_by_id($category_id, $data) 
    { 
     $this->db->where('category_id', $category_id); 
     $this->db->update('tbl_category', $data); 
    } 

} 
?> 

下面是控制器的代碼：

<?php 

defined('BASEPATH') OR exit('No direct script access allowed'); 

class Super_Admin extends CI_Controller 
{ 

    public function __construct() 
    { 
     parent::__construct(); 
     $admin_id = $this->session->userdata('admin_id'); 
     if ($admin_id == NULL) 
     { 
      redirect('admin_login', 'refresh'); 
     } 
    } 

    public function edit_category($category_id) 
    { 
     $data     = array(); 
     $data['category_info'] = $this->super_admin_model->select_catgory_info_by_id($category_id); 
     $data['maincontent'] = $this->load->view('admin/edit_category', $data, true); 
     $data['title']   = 'Edit Category'; 
     $this->load->view('admin/admin_master', $data); 
    } 

    public function update_category() 
    { 
     $data       = array(); 
     $category_id     = $this->input->post('category_id', TRUE); 
     $data['category_name']  = $this->input->post('category_name', TRUE); 
     $data['category_description'] = $this->input->post('category_description', TRUE); 
     $data['publication_status'] = $this->input->post('publication_status', TRUE); 
     $this->super_admin_model->update_category_by_id($category_id, $data); 
     $sdata['message']    = "Updated successfully"; 
     $this->session->set_userdata($sdata); 
     redirect('super_admin/edit_category'); 
    } 

} 
?> 

這是我的看法頁：

Answer 1

截至Super_Admin::update_category()你打電話redirect('super_admin/edit_category');末。這使HTTP重定向到由方法Super_Admin::edit_category()處理的URL /super_admin/edit_category。

該方法需要一個參數，但URL中沒有給出這個參數（這是警告）。通知的原因很明顯：由於edit_category()被調用時沒有任何參數，因此其參數$category_id未設置。

你應該叫redirect()像這樣（例如）：

redirect('super_admin/edit_category/'.$category_id);
