ThinkPHP
本文实例讲述了ThinkPHP分组下自定义标签库的实现方法。分享给大家供大家参考。具体如下:
自定义标签库应该位于ThinkPHP\\Extend\\Driver\\TagLib目录下
1 新建标签类库文件名为TagLibBlog.class.php。
2 编辑刚才新建的类库文件,新建一个类,继承TagLib父类
代码如下:
import('TagLib');
class TagLibBlog extends TagLib {
}
3 在类中声明一个protected成员变量$tags
代码如下:
class TagLibBlog extends TagLib {
protected $tags =array(
'mynav'=>array('attr'=>'limit,order','close'=>1)
/* www.bitsCN.com
这里$tags数组内,每个单元也就是每一行代表一个标签,例如{dede:article},我们这里也定义了一个mynav,
然后每一行标签的键名就是标签名,键值是一个数组,该数组包含两个单元,第一个就是attr,就是标签中得属性,以逗号分隔,
如num,typeid等等,close的值如果是0的话就是非闭合标签,1的话就是闭合,意思是要以来结尾
*/
);
}
4 定义了标签后,我们需要实现标签的功能,这里直接在类文件下声明一个函数,以_开头,以标签名 mynav结尾的函数名
代码如下:
public function _mynav($attr,$content){
$attr=$this->parseXmlAttr($attr);
import('@.Class.Tool');
$categories=M('category')->limit($attr['limit'])->order($attr['order'])->select();
$categories=Tool::formatMultiArray($categories);
$str='';
for($i=0;$i
'/[field.id]/',
'/[field.name]/'
);
$replace=array(
$categories[$i]['id'],
$categories[$i]['name']
);
$str.=preg_replace($model,$replace,$content);
}
return $str;
}
定义好标签后,需要在项目公用配置文件中加载标签库
config.php
代码如下:
//加载标签库
'APP_AUTOLOAD_PATH'=>'@.TagLib',
'TAGLIB_BUILD_IN'=>'Cx,Blog',
标签库完整源码如下:
import('TagLib');
class TagLibBlog extends TagLib {
protected $tags=array(
'mynav'=>array('attr'=>'limit,order','close'=>1)
);
public function _mynav($attr,$content){
$attr=$this->parseXmlAttr($attr);
import('@.Class.Tool');
$categories=M('category')->limit($attr['limit'])->order($attr['order'])->select();
$categories=Tool::formatMultiArray($categories);
$str='';
for($i=0;$i
'/[field.id]/',
'/[field.name]/'
);
$replace=array(
$categories[$i]['id'],
$categories[$i]['name']
);
$str.=preg_replace($model,$replace,$content);
}
return $str;
}
}
?>

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
