问题描述
我编写了一个简单的display_messages()
函数,该函数将在Session::get('errors')
中搜索闪存数据并将其回显到屏幕上.
I've written a simple display_messages()
function that will search Session::get('errors')
for flash data and echo it to the screen.
该功能放在哪里?在Codeigniter中,您有一个helpers文件夹,您可以在其中粘贴所有小的全局助手方法.
Where do I put this function? In Codeigniter, you had a helpers folder where you could stick all your little global helper methods.
推荐答案
按照乌斯曼的建议,
- 创建文件/application/libraries/demo.php
- 在其中定义一个
class Demo() {
- 这样调用函数:
{{ Demo::display() }}
- create a file /application/libraries/demo.php
- define a
class Demo() {
inside it - call the function like so:
{{ Demo::display() }}
有效,因为库和模型是在start.php第76行中自动加载的.我相信文件名必须与类名匹配(注意大写).
Works because libraries and models are autoloaded in start.php line 76. I believe that filenames must match Classnames (note capital).
<?php
class Demo {
public static function display() {
if( !$message = Session::get('errors'))
$message = 'No Errors';
echo "<pre>print_r($message)</pre>";
}
}
无法完全弄清楚为什么我在使用通用类名时会遇到问题,可能会发生冲突(如果这很重要,则可以定义一个名称空间)...
Can't quite figure out why I had a problem using the classname Common, there may be a conflict (you could define a namespace if this were important)...
