第一次正儿八经用CodeIgniter框架作项目,结果不会定义全局变量,只能在一个controller里定义一个public varable,每一个函数调用,别的controller里还须要从新定义,view里还用不了,必须先传值。php
通过研究,在CI中使用全局变量须要自定义Library的形式定义全局变量,这里我介绍一个用config里配置的方法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();
//这一行必须加
$CI
->load->vars(
$data
);
}
}
|
二:/config/globals.php <-名字必须和library一致,定义具体变量session
<?php
if
( ! defined(
'BASEPATH'
))
exit
(
'No direct script access allowed'
);
$config
[
'globals_text'
] =
"test text"
;
$config
[
'globals_text1'
] =
"test text11"
;
|
三:/config/autoload <-配置自动加载项,加载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'
);
|
如今定义了两个变量globals_text和globals_text1就能够在全部MVC中使用了框架
