在thinkphp模板中循环数组没有循环出所需要的数据
我在项目配置文件config.php里面写了个数组,代码
/*网站左侧栏目导航*/ 'menu' => array( 'headnav' => '控制面板', 'subnav' => array( array('name' => '系统设置', 'menumark' => 'System', 'url' => 'System/index'), array('name' => '导航管理', 'menumark' => 'Nav', 'url' => 'Nav/navList'), array('name' => '广告图片', 'menumark' => 'Show', 'url' => 'Show/showList'), array('name' => '管理列表', 'menumark' => 'Admin', 'url' => 'Admin/adminList'), ), ),
在模板里面的代码是这样的,如下:
<foreach name='menu' key='k' item='v'> <div class="fenlei"> <h3 id="s-s-v-headnav"><s></s>{$v.headnav}</h3> <ul > <volist name='v["subnav"]' key='k2' id='v2'> <li><a href="">{$v2.name}</a></li> </volist> </ul> <div class="clear"></div> </div> </foreach>
郁闷死个人,我以前写过另外一个框架,可以用,但是移植到thinkphp就不行了。
回复讨论(解决方案)
foreach里面menu的值你是怎么来的…
config.php里面写的数组要在使用的时候,需要用C()方法获取,你在控制器里先$this->assign('menu', C('menu'));再去遍历它

我在公共控制器里面赋值了的,可以打印出来
你搞错了循环的对象,修改的部分代码参考如下:
<h3 id="s-s-if-nbsp-condition-k-nbsp-eq-nbsp-headnav-menu-headnav-if"> <s></s><if condition='$k eq "headnav"'>{$menu["headnav"]}</if> </h3> <if condition='$k EQ "subnav"'> <ul > <volist name='$menu["subnav"]' key='k2' id='v2'> <li><a href="">{$v2.name}</a></li> </volist> </ul> </if>

这个好像也不对呢,取不出下一级数组
把volist标签换成foreach标签试试
<foreach name='$menu["subnav"]' key='k2' item='v2'> <li><a href="">{$v2.name}</a></li> </foreach>
把volist标签换成foreach标签试试
<foreach name='$menu["subnav"]' key='k2' item='v2'> <li><a href="">{$v2.name}</a></li> </foreach>
这个跟循环标签没关系,楼主原来写法没有错,是跟定义的数组有关系,照这样只能循环出来一组数组。
在config.php里面正确定义数组应该是这样的:
/*网站左侧栏目导航*/ 'menu' => array( 'menu[1]' => array( 'headnav' => '控制面板', 'subnav' => array( array('name' => '网站设置', 'menumark' => 'System', 'url' => 'System/index'), array('name' => '导航管理', 'menumark' => 'Nav', 'url' => 'Nav/navList'), array('name' => '广告管理', 'menumark' => 'Show', 'url' => 'Show/showList'), array('name' => '管理列表', 'menumark' => 'Admin', 'url' => 'Admin/adminList'), ) ), 'menu[2]' => array( 'headnav' => '单页面管理', 'subnav' => array( array('name' => '单页面管理', 'menumark' => 'Page', 'url' => 'Page/pageList'), ) ), ),
改下配置数组就可以了,模板的循环标签是正确的。

我对着这个方法改了下没有问题,数组循环出来了,谢谢了!
