我正在尝试实现Dashboard widget类(在这里找到:http://harpanet.com/programming/php/codeigniter/dashboard/index#installation)但是它给了我错误Unable to load the requested class
我试图在自动加载和手动添加这个类到我的控制器,$this->load->library('dash')
但这也给出了同样的错误.
我检查过dash.php
并找到了以下方法,private function __example__()
但无法理解开发人员在评论中所说的内容.
class Dash { private function __example__() { /* * This function is purely to show an example of a dashboard method to place * within your own controller. */ // load third_party hArpanet dashboard library $this->load->add_package_path(APPPATH.'third_party/hArpanet/hDash/'); $dash =& $this->load->library('dash'); $this->load->remove_package_path(APPPATH.'third_party/hArpanet/hDash/'); // configure dashboard widgets - format: type, src, title, cols, alt (for images) $dash->widgets = array( array('type'=>'oop', 'src'=>'test_dash', 'title'=>'Test OOP Widget', 'cols'=>3), // if 'title' is set to FALSE, the title block is omitted entirely // note: this is an 'html' widget but is being fed content from a local method array('type'=>'html', 'src'=>self::test_method(), 'title'=>false, 'cols'=>3), array('type'=>'file', 'src'=>'saf_inv.htm', 'title'=>'Safety Investigation'), // multi-content widget - set widget title in outer array (also note use of CI anchor to create a link) array('title'=>anchor('tz', 'TARGET ZERO'), // sub-content follows same array format as single content widget // 'img' content can also have an 'alt' text array('type'=>'img', 'src'=>'saf_tzout.gif', 'alt'=>'Action Completed'), array('type'=>'file', 'src'=>'saf_tz.htm'), array('type'=>'file', 'src'=>'ave_close.htm', 'title'=>'Average Time to Close') ), array('type'=>'file', 'src'=>'saf_meet.htm', 'title'=>'Safety Meeting'), array('type'=>'file', 'src'=>'saf_acc.htm', 'title'=>'Accident Investigation'), array('type'=>'file', 'src'=>'saf_hazmat.htm', 'title'=>anchor('hazmat', 'HAZMAT')), array('type'=>'file', 'src'=>'saf_cont.htm', 'title'=>'Loss of Containment'), array('type'=>'file', 'src'=>'saf_worksinfo.htm', 'title'=>'Works Information'), // an action widget - 'clear' will generate a blank widget with a style of clear:both array('type'=>'clear'), // multi-content widget - width can be set using the 'cols' param in outer array array('title'=>'RAG Report', 'cols' => 2, array('type'=>'file', 'src'=>'saf_rag.htm'), array('type'=>'img', 'src'=>'ProcSaf.gif')), array('type'=>'file', 'src'=>'saf_chrom.htm', 'title'=>'Chrome checks'), ); // populate the view variable $widgets = $dash->build('safety'); // render the dashboard $this->load->view('layout_default', $widgets); } ................... } // end of Dash class
安装路径是 root/application/third_party/hArpanet/hDash/libraries/dash.php
如何将此类加载到我的系统并使用小部件?
您必须创建一个初始化第三方类的库:
对于Eg:
- 在库中创建一个名为mydash.php的文件-
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class MyDash { public function __construct() { require_once APPPATH.'third_party/hArpanet/hDash/libraries/dash.php'; } }
使用以下方式加载库:
$this->load->library('mydash');
那么你就可以使用Dash类了.也可以在自动加载中加载库.
谢谢...
