How to get show_error() in CodeIgniter to load a view?

由 天大地大妈咪最大 提交于 2019-12-31 02:57:27
问题 I need to load a head view and a foot view in all my pages. But show_error uses its own complete template. And it stops execution after it loads this template, so the footer wouldn't even load if I wanted to. Should I override this method or is there another way? 回答1: You can create a custom layout to the error messages in the application/errors directory. EDIT: If you want to use your existing files you can do one of the following: If you only require the 404 error page, you can set a custom

问题 Here's the thing. I have friendly urls like http://site.com/blog/read/мъдростта-на-вековете http://site.com/blog/read/green-apple The last segment is actually the friendly title of the blog article. The problem is when I try to pass that segment to the database, the cyrillic fonts turn into something like %D1%8A%D0%B4%D1%80%D0%BE%D1%81%D1%8 and couldn't match the database record. In the address bar in my browser it looks normal ( мъдростта-на-вековете ) but if I choose 'copy url location' the

Codeigniter db->update() VS MySQL native UPDATE Affected rows: 0

由 ℡╲_俬逩灬. 提交于 2019-12-31 02:01:46
问题 Using MySQL alone - If I make a basic update to a table like this: UPDATE `SOMETABLE` SET `NAME` = 'John' WHERE `ID` = 1; And the value of NAME = ' John ' was already ' John ' - in other-words - nothing is new, nothing to update. MySQL returns " Affected rows: 0 (Query took 0.0007 sec) " If I make the same call - now using CodeIgniter - and then retrieve the affected rows like this: $data = array( 'NAME' => 'John' ); $this->db->where('ID', 1); $this->db->update('SOMETABLE', $data); $affect =

Hooks in Codeigniter

由 核能气质少年 提交于 2019-12-31 00:23:05
问题 How can I call a hook for only a few controllers instead of all controllers in CodeIgniter? E.g.: I want to run the hook for only the admin section. How can I achieve this? 回答1: In the hook which you wish to run selectively, you can access the ci superobject using $this->ci =& get_instance(); . This acts as a pointer which can be used to access the CodeIgniter router to determine the class using $class = $this->ci->router->fetch_class(); . You can then check if $class matches a certain value.

Codeigniter 用户登录注册模块

Codeigniter 用户登录注册模块 以下皆是基于Codeigniter + MySQL 一、要实现用户登录注册功能，首先就要和MySQL数据库连接，操作流程如下： CI中贯彻MVC模型，即Model +　View + Controller。数据模型Model处理数据库的运算，视图View顾名思义即使将数据显示出来的页面，而控制器Controller是用来代理完成某项任务的PHP类，Controller充当MVC架构应用程序的“粘合剂”。再回到数据模型，通过创建控制器类，可以对数据库或者其他数据存储方式进行取回、插入和更新。CI中要使用数据库，首先要在配置文件“application/config/database.php”中对数据库进行配置，包括数据库名、用户名、密码等。以下代码段继承控制器CI_Model类，获得数据表‘news’，并对数据表‘news’进行了读和写的简单操作： <?php class News_model extends CI_Model{ public function __construct() { $this->load->database(); } public function get_news($slug = FALSE) { if($slug == FALSE) { $query = $this->db->get('news'); //获得
