ThinkPHP自动完成中使用函数与回调方法实例,thinkphp回调

本文实例讲述了ThinkPHP自动完成中使用函数与回调方法。分享给大家供大家参考。具体方法如下:

ThinkPHP 自动填充格式如下:

复制代码 代码如下:

array(填充字段,填充内容[,填充条件][,附加规则])

附加规则,可选,包括:

string:字符串,表示填充内容为字符串(默认)。

function:使用函数,表示填充的内容是一个函数返回值。

callback:使用方法,表示填充的内容是一个当前 Model 的方法返回值。

field:字段,表示填充的内容是一个其他字段的值。

ThinkPHP 自动填充使用函数function

当附加规则使用函数function填充时,表示填充的内容是一个函数返回值,这个函数可以是PHP内置函数或用户自定义函数.

使用函数填充例子:

复制代码 代码如下:

class UserModel extends Model{  
protected $_auto = array (  
// 对password字段在所有情况下使用md5函数处理  
array('password','md5',3,'function'),  
// 对regdate字段在新增时写入当前时间戳  
array('regdate','time',1,'function'),  
// 对regip字段在新增时写入用户注册IP地址  
array('regip','get_client_ip',1,'function'),  
// 对username字段在新增时使用自定义getName函数  
array('username','get_name',1,'function'),  
);  
}


在上面的例子中,使用的 md5 和 time 为 PHP 内置函数,填充结果为 md5($_POST['password']) 值和 time() 函数值,get_client_ip 和 get_name 为 Common/common.php 自定义函数.

get_name 函数将用户名加上 th_ 前缀,参考如下:

复制代码 代码如下:

function get_name($name){  
return 'th_'.$name;  
}


如果函数需要参数,则将填充字段作为参数,如上面的 md5 和 get_name 函数填充.

ThinkPHP 自动填充使用方法callback

当使用方法 callback 填充时,表示填充的内容是一个当前 Model 的方法返回值,使用 callback 填充例子:

复制代码 代码如下:

class UserModel extends Model{  
protected $_auto = array (  
// 对username字段在新增时回调getName方法  
array('username','getName',1,'callback'),  
);  
}


getName方法将用户名加上 th_ 前缀,参考如下:

复制代码 代码如下:

class UserModel extends Model{  
// 将传入的username加上th_前缀  
function getName(){  
return 'th_'.$_POST['username'];  
}  
}


注:上述例子将 username 字段前自动加上 th_ 前缀而填充到 username 中,仅是为了说明自动填充使用函数或回调方法的用法,可能并无实际生产意义

希望本文所述对大家的ThinkPHP框架程序设计有所帮助。

Automount drives on Linux Automount drives on Linux Mar 20, 2024 am 11:30 AM

If you are using a Linux operating system and want the system to automatically mount the drive on boot, you can do this by adding the device's unique identifier (UID) and mount point path to the fstab configuration file. fstab is a file system table file located in the /etc directory. It contains information about the file systems that need to be mounted when the system starts. By editing the fstab file, you can ensure that the required drives are loaded correctly every time the system starts, thus ensuring stable system operation. Automatically mounting drivers can be conveniently used in a variety of situations. For example, I plan to back up my system to an external storage device. To achieve automation, ensure that the device remains connected to the system, even at startup. Likewise, many applications will directly
