ThinkPHP自动完成中使用函数与回调方法实例
这篇文章主要介绍了ThinkPHP自动完成中使用函数与回调方法,实例分析了ThinkPHP中自动填充的用法以及使用函数与回调的方法,是非常实用的技巧,需要的朋友可以参考
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。

Go language provides two dynamic function creation technologies: closure and reflection. closures allow access to variables within the closure scope, and reflection can create new functions using the FuncOf function. These technologies are useful in customizing HTTP routers, implementing highly customizable systems, and building pluggable components.

In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

1. The SUM function is used to sum the numbers in a column or a group of cells, for example: =SUM(A1:J10). 2. The AVERAGE function is used to calculate the average of the numbers in a column or a group of cells, for example: =AVERAGE(A1:A10). 3. COUNT function, used to count the number of numbers or text in a column or a group of cells, for example: =COUNT(A1:A10) 4. IF function, used to make logical judgments based on specified conditions and return the corresponding result.

The key to writing efficient and maintainable Java functions is: keep it simple. Use meaningful naming. Handle special situations. Use appropriate visibility.
