本文實例講述了smarty循環嵌套用法。分享給大家供大家參考,具體如下:
test3.php:
<?phprequire "main.php";$forum = array( array("category_id" => 1, "category_name" => "公告區", "topic" => array( array("topic_id" => 1, "topic_name" => "站務公告") ) ), array("category_id" => 2, "category_name" => "文學專區", "topic" => array( array("topic_id" => 2, "topic_name" => "好書介紹"), array("topic_id" => 3, "topic_name" => "奇文共賞") ) ), array("category_id" => 3, "category_name" => "電腦專區", "topic" => array( array("topic_id" => 4, "topic_name" => "硬件周邊"), array("topic_id" => 5, "topic_name" => "軟件討論") ) ));$tpl->assign("forum", $forum);$tpl->display("test3.htm");?>
樣版的寫法如下:
templates/test3.htm:
<html><head><title>循環嵌套測試</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:
<?phprequire_once('./include/db_fns.php');include_once("./Smarty/libs/Smarty.class.php"); //包含Smarty類文件$smarty = new Smarty(); //建立Smarty實例對象$Smarty$smarty->template_dir = "./templates/dedecms";//設置模板目錄$smarty->compile_dir = "templates/templates_c"; //設置編譯目錄$smarty->assign("template_url", "./");$smarty->assign("$site_url", "http://www.49028c.com/");$smarty->assign("$site_name", "文章管理系統");$smarty->left_delimiter = "<{"; //設置左邊界符$smarty->right_delimiter = "}>"; //設置右邊界符$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>嵌套循環測試</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:
<?phprequire "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');?>
模版的寫法如下:
templates/test4.htm:
<html><head><title>橫向重復表格測試</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 div by 2}></tr><tr><{/if}><{/section}></tr></table></body></html>
重點在于 $smarty.section.sec1.rownum 這個 Smarty 變量,在 section 循環中這個變量會取得從 1 開始的索引值,所以當 rownum 能被 2 除盡時,就輸出 </tr><tr> 使表格換列 (注意!是 </tr> 在前面<tr> 在后面) 。因此數字 2 就是我們在一列中想要呈現的資料筆數。各位可以由此去變化其它不同的呈現方式。
運算符有以下這些:
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:
<!--{if $bigsize ge '650'}--> <img src="photo/<!--{$photo}-->" border="0" width="650" class="product_photo" /><!--{else}--> <img src="photo/<!--{$photo}-->" border="0" class="product_photo" /><!--{/if}-->
以前不常用smarty,這兩天有個朋友的網站要改;順手用了一下,還是挺有意思的。
關于capture 的說明:
capture函數的作用是收集模板輸出的數據到一個變量里,而不是把它們輸出到頁面.
任何在 {capture name="foo"}和{/capture}之間的數據都被收到了由函數的名稱屬性指定的變量里($foo).
收集的信息可以用在特殊變量$smarty里.
例如capture.foo就收集了以上數據.如果函數沒有名字屬性,將使用"default".
每個{capture}都必須對應{/capture},也不能嵌套使用capture函數.
希望本文所述對大家基于smarty模板的PHP程序設計有所幫助。
