第一次正兒八經用CodeIgniter框架作項目,結果不會定義全局變量,只能在一個controller裏定義一個public varable,每一個函數調用,別的controller裏還須要從新定義,view裏還用不了,必須先傳值。php
通過研究,在CI中使用全局變量須要自定義Library的形式定義全局變量,這裏我介紹一個用config裏配置的方法html
一:library/globals.php web
<?php
if
( ! defined(
'BASEPATH'
))
exit
(
'No direct script access allowed'
);
class
Globals
{
function
__construct(
$config
=
array
() ){
foreach
(
$config
as
$key
=>
$value
) {
$data
[
$key
] =
$value
;
}
$CI
=& get_instance();
//這一行必須加
$CI
->load->vars(
$data
);
}
}
|
二:/config/globals.php <-名字必須和library一致,定義具體變量session
<?php
if
( ! defined(
'BASEPATH'
))
exit
(
'No direct script access allowed'
);
$config
[
'globals_text'
] =
"test text"
;
$config
[
'globals_text1'
] =
"test text11"
;
|
三:/config/autoload <-配置自動加載項,加載global libraryapp
/*
| -------------------------------------------------------------------
| Auto-load Libraries
| -------------------------------------------------------------------
| These are the classes located in the system/libraries folder
| or in your application/libraries folder.
|
| Prototype:
|
| $autoload['libraries'] = array('database', 'session', 'xmlrpc');
*/
$autoload
[
'libraries'
] =
array
(
'globals'
);
|
如今定義了兩個變量globals_text和globals_text1就能夠在全部MVC中使用了框架
