本文实例讲述了smarty循环嵌套用法。分享给大家供大家参考,具体如下:
test3.php:
1, "category_name" => "公告区", "topic" => array( array("topic_id" => 1, "topic_name" => "站务公告") ) ), array("category_id" => 2, "category_name" => "文学专区", "topic" => array( array("topic_id" => 2, "topic_name" => "好书介绍"), array("topic_id" => 3, "topic_name" => "奇文共赏") ) ), array("category_id" => 3, "category_name" => "电脑专区", "topic" => array( array("topic_id" => 4, "topic_name" => "硬件周边"), array("topic_id" => 5, "topic_name" => "软件讨论") ) ));$tpl->assign("forum", $forum);$tpl->display("test3.htm");?>
样版的写法如下:
templates/test3.htm:
<title>循环嵌套测试</title><body><table width="200" border="0" align="center" cellpadding="3" cellspacing="0"> <tr> <td colspan="2"></td> </tr> <tr> <td width="25"> </td> <td width="164"></td> </tr> </table>
test2.php:
template_dir = "./templates/dedecms";//设置模板目录$smarty->compile_dir = "templates/templates_c"; //设置编译目录$smarty->assign("template_url", "./");$smarty->assign("$site_url", "http://www.php.net/");$smarty->assign("$site_name", "文章管理系统");$smarty->left_delimiter = "right_delimiter = "}>"; //设置右边界符$db_conn = db_connect();$query = "SELECT cat_ID,cat_name FROM categories ORDER BY cat_ID DESC";$result = mysql_query($query);$i = 5;while(($row = mysql_fetch_array($result)) && $i > 0){ $query2="SELECT ID, post_title, post_date FROM post WHERE post.post_category =$row[cat_ID] AND post_status 'unpbulish' ORDER BY post_date DESC"; $result2=mysql_query($query2); $i = 5; while(($row2 = mysql_fetch_array($result2)) && $i > 0) { $row2[post_date]=date('m-d',strtotime($row2[post_date])); $category = array("cat_ID"=>"$row[cat_ID]","cat_name"=>"$row[cat_name]", "post"=>array("ID"=>"$row2[ID]", "post_title"=>"$row2[post_title]" , "post_category"=>"$row2[post_category]" , "post_date"=>"$row2[post_date]")); $i--; }}$smarty->assign("forum", $category);$smarty->display("test2.htm");?>
test2.htm:
<title>嵌套循环测试</title> <body> <table width="200" border="0" align="center" cellpadding="3" cellspacing="0"> <tr> <td colspan="2"></td> </tr> <tr> <td width="25"> </td> <td width="164"></td> </tr> </table>
test4.php:
"0"),array("value" => "1"),array("value" => "2"),array("value" => "3"),array("value" => "4"),array("value" => "5"),array("value" => "6"),array("value" => "7"),array("value" => "8"),array("value" => "9"));$tpl->assign("my_array", $my_array);$tpl->display('test4.htm');?>
模版的写法如下:
templates/test4.htm:
<title>横向重复表格测试</title><body><table width="500" border="1" cellspacing="0" cellpadding="3"><tr><td></td></tr><tr></tr></table>
重点在于 $smarty.section.sec1.rownum 这个 Smarty 变量,在 section 循环中这个变量会取得从 1 开始的索引值,所以当 rownum 能被 2 除尽时,就输出
在前面
运算符有以下这些:
eq、ne、neq、gt、lt、lte、le、gte、ge、is even、is odd、is not even、is not odd、not、mod、div by、even by、odd by
示例:
<!---ecms {if $bigsize ge '650'}--> " border="0" width="650" class="product_photo" /><!---ecms {else}--> " border="0" class="product_photo" /><!---ecms {/if}-->
以前不常用smarty,这两天有个朋友的网站要改;顺手用了一下,还是挺有意本文来源gaodaimacom搞#^代%!码&网*
搞代gaodaima码
思的。
关于capture 的说明:
capture函数的作用是收集模板输出的数据到一个变量里,而不是把它们输出到页面.
任何在 {capture name=”foo”}和{/capture}之间的数据都被收到了由函数的名称属性指定的变量里($foo).
收集的信息可以用在特殊变量$smarty里.
例如capture.foo就收集了以上数据.如果函数没有名字属性,将使用”default”.
每个{capture}都必须对应{/capture},也不能嵌套使用capture函数.
希望本文所述对大家基于smarty模板的PHP程序设计有所帮助。
