Smarty 3.1.8 中的注册函数 registerPlugin使用问题
在学习smarty中遇到了这样一个问题
在php文件中我这样写
function demo($params){ extract($params); echo $a.$b; } $tpl->registerPlugin('block','demo','demo');然后在模板 文件中这样写：
<body> <{demo a=1 b=text}> <{/demo}> </body>输出的时候怎么输出了两个 1text 1text
求解决！
回复讨论(解决方案)
去掉这个“ <{/demo}>”？
去掉的话 就会发生错误
木写过插件，这这例子有帮助没？

这个我看了
我就是按照这个来写的
呵呵，我试试
smarty 3.1.7例子没有问题
$smarty = new Smarty;$smarty->registerPlugin("function","demo", "demotest");;//制定类型，这里制定是函数调用，指定模板函数名称和php函数名称function demotest($params) { extract($params);//获取参数a与b了 echo $a.$b;//输出}{demo a="2" b="test"}
$smarty->registerPlugin("function","demo", "demotest")的确没有问题
我说的是
$smarty->registerPlugin("block","demo", "demotest")再试试
问题还是没有解决
你看看手册中的示例
// function declarationfunction do_translation ($params, $content, $smarty, &$repeat, $template){ if (isset($content)) { $lang = $params["lang"]; // do some translation with $content return $translation; }}// register with smarty$smarty->registerPlugin("block","translate", "do_translation");{translate lang="br"}Hello, world!{/translate}
问题还是没有解决
估计block的插件会调用两次
例子我看了 例子还是出现了错误

block方式的会执行两次。通过 if (isset($content)) {，做了判断所以只执行了一次。

3q 问题解决了！！
block会出现两次，算是smarty的一个bug吧。但不影响使用。
function test2($arr,$content){ print_r($arr); //$html = "<div style='font-size:".$arr["size"]."px;color:".$arr["color"]."'>".$content."</div>"; //return $html;}$smarty->registerPlugin("block","test2","test2");<{test2 size="30" color="#ff0000"}>Hello World<{/test2}>输出：
Array ( [size] => 30 [color] => #ff0000 ) Array ( [size] => 30 [color] => #ff0000 )

Tips for dynamically creating new functions in golang functions
Apr 25, 2024 pm 02:39 PM
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.
Considerations for parameter order in C++ function naming
Apr 24, 2024 pm 04:21 PM
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.

Comparison of the advantages and disadvantages of C++ function default parameters and variable parameters
Apr 21, 2024 am 10:21 AM
The advantages of default parameters in C++ functions include simplifying calls, enhancing readability, and avoiding errors. The disadvantages are limited flexibility and naming restrictions. Advantages of variadic parameters include unlimited flexibility and dynamic binding. Disadvantages include greater complexity, implicit type conversions, and difficulty in debugging.
What are the benefits of C++ functions returning reference types?
Apr 20, 2024 pm 09:12 PM
The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.
What is the difference between custom PHP functions and predefined functions?
Apr 22, 2024 pm 02:21 PM
The difference between custom PHP functions and predefined functions is: Scope: Custom functions are limited to the scope of their definition, while predefined functions are accessible throughout the script. How to define: Custom functions are defined using the function keyword, while predefined functions are defined by the PHP kernel. Parameter passing: Custom functions receive parameters, while predefined functions may not require parameters. Extensibility: Custom functions can be created as needed, while predefined functions are built-in and cannot be modified.
C++ Function Exception Advanced: Customized Error Handling
May 01, 2024 pm 06:39 PM
Exception handling in C++ can be enhanced through custom exception classes that provide specific error messages, contextual information, and perform custom actions based on the error type. Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.
