这篇文章主要介绍了smarty循环嵌套用法,结合实例形式分析了Smarty模板嵌套循环的实现技巧与相关注意事项,需要的朋友可以参考下
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:
<?php require "main.php"; $forum = array( array("category_id" => 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); $tpl->display("test3.htm"); ?>
样版的写法如下:
templates/test3.htm:
<html> <head> <title>循环嵌套测试</title> </head> <body> <table width="200" border="0" align="center" cellpadding="3" cellspacing="0"> <{section name=sec1 loop=$forum}> <tr> <td colspan="2"><{$forum[sec1].category_name}></td> </tr> <{section name=sec2 loop=$forum[sec1].topic}> <tr> <td width="25"> </td> <td width="164"><{$forum[sec1].topic[sec2].topic_name}></td> </tr> <{/section}> <{/section}> </table> </body> </html>
test2.php:
<?php require_once('./include/db_fns.php'); include_once("./Smarty/libs/Smarty.class.php"); //包含Smarty类文件 $smarty = new Smarty(); //建立Smarty实例对象$Smarty $smarty->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", "//www.jb51.net/"); $smarty->assign("$site_name", "文章管理系统"); $smarty->left_delimiter = "<{"; //设置左边界符 $smarty->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); $smarty->display("test2.htm"); ?>
test2.htm:
<html> <head> <title>嵌套循环测试</title> </head> <body> <table width="200" border="0" align="center" cellpadding="3" cellspacing="0"> <{section name=sec1 loop=$forum}> <tr> <td colspan="2"><{$forum[sec1].cat_id}></td> </tr> <{section name=sec2 loop=$forum[sec1].post}> <tr> <td width="25"> </td> <td width="164"><{$forum[sec1].post[sec2].post_title}></td> </tr> <{/section}> <{/section}> </table> </body> </html>
test4.php:
<?php require "main.php"; $my_array = array( array("value" => "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); $tpl->display('test4.htm'); ?>
模版的写法如下:
templates/test4.htm:
<html> <head> <title>横向重复表格测试</title> </head> <body> <table width="500" border="1" cellspacing="0" cellpadding="3"> <tr> <{section name=sec1 loop=$my_array}> <td><{$my_array[sec1].value}></td> <{if $smarty.section.sec1.rownum is p by 2}> </tr> <tr> <{/if}> <{/section}> </tr> </table> </body> </html>
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
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、p by、even by、odd by
示例:
<!--{if $bigsize ge '650'}--> <img src="photo/<!--{$photo}-->" border="0" width="650" class="product_photo" /> <!--{else}--> <img src="photo/<!--{$photo}-->" border="0" class="product_photo" /> <!--{/if}-->
以前不常用smarty,这两天有个朋友的网站要改;顺手用了一下,还是挺有意思的。
关于capture 的说明:
capture函数的作用是收集模板输出的数据到一个变量里,而不是把它们输出到页面.
任何在 {capture name="foo"}和{/capture}之间的数据都被收到了由函数的名称属性指定的变量里($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.
