HomeBackend DevelopmentPHP Tutorial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>

                    <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!

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
