A summary of common knowledge points in CodeIgniter, a summary of codeigniter

This article briefly summarizes the common knowledge points in CodeIgniter development. Share it with everyone for your reference, the details are as follows:

Jump:

$this->load->helper('url');
redirect();

Constant definition:

config/constants.php

About language files:

I’ll just talk about my own approach. In order to uniformly manage error messages, I decided to make an error_lang.php

Create a new folder chinese under application/language and create a new file error_lang.php

In config.php:

$config['language']  = "english";

was changed to:

$config['language']  = "chinese";

If necessary, you can automatically load the error in autoload.php

$autoload['language'] = array('error');

error_lang.php file content

<&#63;php
$lang['error_user_login'] = "用户名或密码有误|请检查您的输入后，重新登陆";
&#63;>

When using it, use the following statement

$this->lang->load('error');
$this->lang->line('error_user_login');

Let CodeIgniter support $_GET

Solution:

1) In config.php, set ‘uri_protocol’ to ‘PATH_INFO’.

$config [ 'uri_protocol' ] = "PATH_INFO" ;

2) Add:
before you need to use $_GET

parse_str ( $_SERVER [ 'QUERY_STRING' ] , $_GET ) ;

In this way, something like index.php/blog/list?parm=hello&page=52 can be run.
