Question

在html页面    smarty如何实现i++
如何把下面这段C#代码翻译成smarty下的代码？
<%
                   int i_count = 0; 
                   foreach (GridViewRow row in this.GridView1.Rows)
                   {
                          if (i_count%4 == 0)
                          {
%>
                                 <div>.1..<div>
<%
                          }
                          else
                           {
%>
                                 <div>.2..<div>
<%
                            }
                           i_count ++ ;
                    }
%>我写的是这样，但是ERROR
                   {assign var="i_count"}
                   {foreach from=$row item=item}
                   
                          {if $i_count mod 4}
                          
                                 <div>.2..<div>
                        
                          {else}
                           
                                 <div>.1..<div>
                           {/if}                           {$i_count + 1 }
                    {/foreach}请问如何写？是我i++写错了吗

Answer 1

你为什么要这样写？  smarty  foreach 里面可以获取当前key 的 {foreach from=$var key=k item=v}
这个k就是了 呵呵

Answer 2

{assign var="i_count" value=0}
                   {foreach from=$row item=item}
                    
                          {if $i_count mod 4}
                           
                                 <div>.2..<div>
                         
                          {else}
                            
                                 <div>.1..<div>
                           {/if}
 
{assign var="i_count" value=$i_count+1}
                    {/foreach}没测试， 不行的话就把$i_count+1用``引起来

Answer 3

貌似要''引起来，但是为什么我的代码就第一次执行第一个div里的，后面都执行第二个div里的内容？                    {if $i_count mod 4 == 0}
                   <div>.1..<div>
                   {else}
                    <div>.2..<div>
                   {/if} 

Answer 4

{foreach from=$row item=item key=i_count}
                  
                          {if $i_count mod 4}
                            
                                 <div>.2..<div>
                          
                          {else}
                             
                                 <div>.1..<div>
                           {/if}

Answer 5

{foreach from=$row item=item key=i_count}
{if ($i_count mod 4)==0}
<div>.2..<div>
{else}
<div>.1..<div>
{/if}

Answer 6

这句可以这么写.{if ($i_count mod 4) eq 0}
