smarty模板新手问题:提示在模板中发现未定义函数
模板代码:

PHP code
<!--

http://www.CodeHighlighter.com/

-->{include file ='header.tpl'}

{$tableName}

姓名:
测试:
{include file ='footer.tpl'}

index.php调用代码:
PHP code
<!--

Code highlighting produced by Actipro CodeHighlighter (freeware)
http://www.CodeHighlighter.com/

--><?php require_once dirname(__FILE__) . "\include\common.inc.php";
require_once SR_TEMPLATE . "\TemplatesFunction.php";
     $smarty = $GLOBALS['smarty'];
     $smarty -> assign('title','测试标题'); 
     $smarty -> assign('Version',"2011"); 
     $smarty -> assign('HomePageLink','http://localhost/Matance1.0/'); 
     $smarty -> assign('tableName','标题'); 
    

    
    if(isset($_POST['ceshi2'])){
          $smarty -> assign('wandoujia',$_POST['ceshi2']); 
     }
    $smarty -> display('index.tpl');
?>


即在index.tpl模板上作一表单,action="index.php",index.php在加载模板时判断有木有传值,如果有,则给模板中$wandoujia函数传值

但运行后,总是提示:

Notice: Undefined index: wandoujia in D:\Program Files\wamp\www\Mantance1.0\TemplateFile\Templates\default\templates_c\da1ad7986fcfc741270ca7b7bdceba8d01b88c26.file.index.tpl.php on line 34
Notice: Trying to get property of non-object in D:\Program Files\wamp\www\Mantance1.0\TemplateFile\Templates\default\templates_c\da1ad7986fcfc741270ca7b7bdceba8d01b88c26.file.index.tpl.php on line 34
/>

求教

------解决方案--------------------
第一,这个不是未定义函数,只是为定义的index,
第二,看看此文件34行即可
D:\Program Files\wamp\www\Mantance1.0\TemplateFile\Templates\default\templates_c\da1ad7986fcfc741270ca7b7bdceba8d01b88c26.file.index.tpl.php
------解决方案--------------------
if(isset($_POST['ceshi2'])){
$smarty -> assign('wandoujia',$_POST['ceshi2']); 
}

没考虑wandoujia没有分配的情况,如果wandoujia没有值自然或报错。
------解决方案--------------------
把错误级别号改为5或者7,只报打错,Notice错误可以直接忽略,对站点运行豪无影响,我们自己早期开发的PHP站点,因为当时写得不规范,至少有上百个NOTICE级别错误,但是依然完美运行几年了。现在大家也懒得去修正。无所谓。
------解决方案--------------------
如果一定要纠正此NOTICE级别的问题,你可以这么做:除了在PHP代码里判断POST提交外:
 if(isset($_POST['ceshi2'])){
$smarty -> assign('wandoujia',$_POST['ceshi2']); 
}
还应该在模板里用SMARTY也判断是否有POST提交。如果有就加入SMARTY变量wandoujia。注意这一段:
 
姓名:

试着改为:
  
姓名:

这里不一定是这样写,你最好直接看看POST提交值的模板的2种输出情况,{$smarty.post.ceshi2}直接插入到一个标签里显示一下。看看有提交值跟没提交值适合{$smarty.post.ceshi2}的输出差别。这样就能判断是否需要加入$wandoujia变量了。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
