What are the common knowledge points of CodeIgniter

This article will explain in detail what are the common knowledge points about CodeIgniter. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Jump:

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

Constant definition:

Config/constants.php

About language files:

I only said that I decided to make an error_lang.php in order to unify the management of error messages.

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

In config.php:

$config ['language'] = "english"

Modified to:

$config ['language'] = "chinese"

Error can be loaded automatically in autoload.php if necessary.

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

Error_lang.php file content

When in use, 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.
