来看看这个图里面的数字应该怎么算出来?
就是这些被红字的数字,每行3个,所有偶数行的数字应该怎么通过数学的方法算出来?
取余的话取的是纵列的数字,怎么样能把红字的偶数行给表达出来?

{wf:if $smarty.section.product.rownum eq 4 or $smarty.section.product.rownum eq 5 or $smarty.section.product.rownum eq 6 or $smarty.section.product.rownum eq 10 or $smarty.section.product.rownum eq 11 or $smarty.section.product.rownum eq 12}要输出的内容{qf:/if}
现在我的写法是这样的,但是明显太不合理了,问下大神怎么写方便
int((n+2)/3) & 1 == 0
其实我要判断的最多也就是4、5、6、7、8、9、16、17、18这九个数字。
for ($n=1;$n if(($n-1)/3%2 != 0)
echo $n."\t";
}
//output: 4 5 6 10 11 12 16 17 18
判定行号是否为偶数
for($i=1;$i for($j=1;$j echo $i*3+$j.' ';
}
echo '
';
}
其实我要判断的最多也就是4、5、6、7、8、9、16、17、18这九个数字。
7、8、9不在偶数行啊?!

7、8、9不在偶数行啊?! 打错了,应该是10、11、12
smarty ??
他不是有个 cycle 控制变量吗?为什么不用!
test.php
include_once("smarty_inc.php"); $arr=array('a','b','c','d','e','f'); $smarty->assign('arr',$arr); $smarty->display("test.tpl");
test.tpl
<table width="100px"> {section name=a loop=$arr} <tr bgcolor="{cycle values="#eeeeee,#55eero"}"> <td> {$arr[a]} </td> </tr> {/section} </table>
