Codeigniter中集成smarty和adodb的方法_php实例
本文实例讲述了Codeigniter中集成smarty和adodb的方法。分享给大家供大家参考,具体如下:
在CodeIgniter中要写自己的库,就需要写两个文件,一个是在application/init下面的init_myclass.php文件(如果没有init目录,自己创建)。另外一个就是在application/libraries目录下创建myclass.php文件。
这里myclass是你的类名。一些规则大家看手册就好了,我这里直接就说步骤了。
1)在application/libraries下分别创建mysmarty.php和adodb.php
mysmarty.php文件的内容如下:
<?php // load Smarty library require('Smarty/Smarty.class.php'); // The setup.php file is a good place to load // required application library files, and you // can do that right here. An example: // require('guestbook/guestbook.lib.php'); class MySmarty extends Smarty { function MySmarty() { // Class Constructor. // These automatically get set with each new instance. $this->Smarty(); $basedir=dirname(__FILE__); $this->template_dir = "$basedir/templates/"; $this->compile_dir = "$basedir/templates_c/"; $this->config_dir = "$basedir/configs/"; $this->cache_dir = "$basedir/cache/"; //$this->compile_check = true; //this is handy for development and debugging;never be used in a production environment. //$smarty->force_compile=true; $this->debugging = false; $this->cache_lifetime=30; $this->caching = 0; // lifetime is per cache //$this->assign('app_name', 'Guest Book'); } } ?>
文件路径根据具体情况修改,文件的的路径是相对你的网站的主目录开始的,而不是当前文件的当前目录,比如上面的require('Smarty/Smarty.class.php');不是相对application/libraries目录,而是相对$_SERVER['DOCUMENT_ROOT']目录。
adodb.php文件的内容如下:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class Adodb { function Adodb() { //$dsn="dbdriver://username:password@server/database" $dsn = 'mysql://user:password@localhost/xxxx'; require_once("adodb/adodb.inc".EXT); $this->adodb =& ADONewConnection($dsn); $this->adodb->Execute("set NAMES 'utf8'"); } } ?>
2)在application/init目录下分别创建init_adodb.php和init_mysmarty.php。
init_adodb.php文件内容如下:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); $obj =& get_instance(); $obj->adodb = new Adodb($obj); $obj->ci_is_loaded[] = 'adodb';
init_mysmarty.php文件内容如下:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); if ( ! class_exists('MySmarty')) { require_once(APPPATH.'libraries/mysmarty'.EXT); } $obj =& get_instance(); $obj->mysmarty = new MySmarty(); $obj->ci_is_loaded[] = 'mysmarty'; ?>
3)使用他们
在application/controllers目录下创建一个你需要的文件,你可以这样来使用adodb和smarty。
<?php class Test extends Controller { function Test() { parent::Controller(); $this->load->library('mysmarty'); $this->load->library('adodb'); } function index() { $this->load->library('adodb'); $row = $this->adodb->adodb->getrow('SELECT * FROM admin'); $this->mysmarty->assign("row",$row); $this->mysmarty->display("test.tpl"); } } ?>
我也不知道这里为什么需要两次adodb,按照官方的做法应该只需要一次,但是他的方法在我这里有错误。可能是我对CodeIgniter还不太了解吧,等深入一些,再看看有没有解决办法。不过至少目前这个可以工作了。
