我只有四条信息，获取的总数是7，有没有直接判断栏目下信息总数的字段

[object Object]

{category module=share pid=1 return=c1}
     <a href="{$c1.url}" class="proItem">
         <div class="proImg"><img src="{dr_get_file($c1.lmlb)}" class="imgs"></div>
         <div class="proText">
             //判断每个栏目下面有多少条信息
             //第一部声明一个变量为0
             <?php
             $key=0;
             ?>
             //循环子栏目信息数量++
             {module module=product catid=$c1.id}
             <?php
             $key=$key+1;
             ?>
             {$t.title}
             {/module}  
             <?php
             $key<=0?$key=0:$key;
             ?>
             //输出总数
              <div class="pxh"><?=$key;?>个型号</div>
              //清空总数
             <?php
             $key=0;
             ?>
              <div class="pxian"></div>
              <div class="pxl">{$c1.name}</div>
              <div class="pjj">{$c1.lmjj}</div>
              <div class="pMore"><span>查看详情</span><img src="{HOME_THEME_PATH}images/p1.png"></div>
         </div>
     </a>
