ThinkPHP模板Volist标签嵌套循环输出多维数组的方法,thinkphpvolist
本文实例讲述了ThinkPHP模板Volist标签嵌套循环输出多维数组的方法。分享给大家供大家参考,具体如下:
ThinkPHP 中对 volist 标签嵌套使用可实现多维数组的输出。
volist 嵌套使用
一般的二维数组,可以用 volist 标签直接循环输出。对于多维数组,则需要对其中的数组成员再次使用 volist 标签嵌套循环输出。
构建一个多维数组:
$food = array(); $food[0]['fruits'][0]['fruits1'] = '苹果1'; $food[0]['fruits'][0]['fruits2'] = '桔子1'; $food[0]['fruits'][0]['fruits3'] = '香蕉1'; $food[0]['vegetables'] = '白菜1'; $food[1]['fruits'][1]['fruits1'] = '苹果2'; $food[1]['fruits'][1]['fruits2'] = '桔子2'; $food[1]['fruits'][1]['fruits3'] = '香蕉2'; $food[1]['vegetables'] = '白菜2';
使用 print_r() 函数打印出该数组如下:
Array ( [0] => Array ( [fruits] => Array ( [0] => Array ( [fruits1] => 苹果1 [fruits2] => 桔子1 [fruits3] => 香蕉1 ) ) [vegetables] => 白菜1 ) [1] => Array ( [fruits] => Array ( [1] => Array ( [fruits1] => 苹果2 [fruits2] => 桔子2 [fruits3] => 香蕉2 ) ) [vegetables] => 白菜2 ) )
在对应模块操作(如Index/display)里将变量赋值给模板,并将模板输出:
$this->assign( "food", $food ); $this->display();
模板 Tpl/default/Index/display.html :
<p>食物品种:</p><br /> <volist name="food" id="vo"> <volist name="vo['fruits']" id="f"> <p>水果1:{$f['fruits1']}</p> <p>水果2:{$f['fruits2']}</p> <p>水果3:{$f['fruits3']}</p> </volist> <p>蔬菜:{$vo['vegetables']}</p><br /> </volist>
在模板里面,首先将 $food 变量进行循环输出。由于 $food 数组的成员 fruits 也是一个数组,因此再对 $vo['fruits'] 变量进行循环输出(注意没有 $ 符号)。
输出结果如下:
食物品种: 水果1:苹果1 水果2:桔子1 水果3:香蕉1 蔬菜:白菜1 水果1:苹果2 水果2:桔子2 水果3:香蕉2 蔬菜:白菜2
同理推之以此方法可以对更多维的数组进行循环输出。
