<for start="开始值" end="结束值" comparison="" step="步进值" name="循环变量名" > </for>
案例
<for start="1" end="100"> {$i} </for>
解析为
for ($i=1;$i<100;$i+=1){ echo $i; }
2.switch用法
<switch name="变量" > <case value="值1" break="0或1">输出内容1</case> <case value="值2">输出内容2</case> <default />默认情况 </switch>
案例
<switch name="User.level"> <case value="1">value1</case> <case value="2">value2</case> <default />default </switch>
也可以对case的value属性使用变量,例如:
<switch name="User.userId"> <case value="$adminId">admin</case> <case value="$memberId">member</case> <default />default </switch>
<for start="0" end="$credit['num']"> <switch name="credit['level']"> <case value="1"><img src="{sh::PUB}img/credit/level-heart2.png" class="star"></case> <case value="2"><img src="{sh::PUB}img/credit/level-diamond2.png" class="star"></case> <case value="3"><img src="{sh::PUB}img/credit/level-crown2.png" class="star"></case> <case value="4"><img src="{sh::PUB}img/credit/level-super-crown2.png" class="star"></case> <default />default </switch> </for>
