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
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ -->{include file ='header.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:
试着改为:
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。
