2.6 应用举例 循环调用子栏目信息以及头条图片

封面模板 可以实现循环子栏目以及头条调用，但是头条的图片和标题只能用一条，只有使用灵动标签。

实现效果如图：

<?php
$bclassid=$GLOBALS[navclassid]; //取得本栏目id
//取得本栏目下的子栏目
?>

[e:loop={"select classid, classname, classpath from `[!db.pre!]enewsclass` where bclassid='$bclassid' order by `classid` desc ",7,24,0}]
<div class="fengm">
  <h3><span><a href="<?=$public_r[newsurl].$bqr[classpath]?>" target="_blank">更多+</a></span>
    <?=$bqr[classname]?>
  </h3>
  <div class="fpicbox">
    <ul>
      <?php
//这里是取得该分类下的有图片的最新数据
$commbook=$empire->query("select * from [!db.pre!]ecms_news where classid = ".$bqr[classid]."  and  titlepic!=' ' order by newstime desc limit 3");
$commbookurl=sys_ReturnBqTitleLink($commbook);
 while($r=$empire->fetch($commbook)) {
    ?>
      <li class="fpic"><a href="<?=sys_ReturnBqTitleLink($r)?>"><img src="<?=$r[titlepic]?>" ><i>
        <?=$r[title]?>
        </i></a></li>
      <?php
     }
 ?>
    </ul>
  </div>
  <ul class="fmnews">
    <?php
//取得该分类下的最新数据
    $newbook=$empire->query("select title,titlepic,smalltext,titleurl,keyboard,newstime,groupid,classid,newspath,filename,id from [!db.pre!]ecms_news  where classid =".$bqr[classid]." order by newstime desc limit 5");
    while($r=$empire->fetch($newbook)) {
    ?>
    <li><span>
      <?=date('Y-m-d',$r[newstime])?>
      </span><a href="<?=sys_ReturnBqTitleLink($r)?>" title="<?=$r[title]?>">
      <?=$r[title]?>
      </a></li>
    <?php
     }
     //显示5条
 ?>
  </ul>
</div>
[/e:loop]

如果首页改用扩展变量，可以这么做 ：系统-扩展变量-增加一个变量名为title

<div class="tab_box whitebg">
  <?php
$bclassid=ReturnPublicAddVar('title'); //取得栏目id，系统，扩展变量
?>
  <div class="tab_buttons">
    <ul>
      [e:loop={"select classid, classname, classpath from [!db.pre!]enewsclass where classid in $bclassid order by myorder asc ",0,24,0}]
      <?
if($bqno==1)
{
?>
      <li class="newscurrent"><a href="javascrpt::">
        <?=$bqr[classname]?>
        </a></li>
      <?php
}
else{
?>
      <li><a href="javascrpt::">
        <?=$bqr[classname]?>
        </a></li>
      <?
}
?>
      [/e:loop]
    </ul>
  </div>
  <div class="newstab"> [e:loop={"select classid, classname, classpath from [!db.pre!]enewsclass where classid in $bclassid order by myorder asc ",0,24,0}]
    <div class="newsitem">
      <div class="newspic">
        <ul>
          <?php
//这里是取得该分类下的有图片的最新数据
$commbook=$empire->query("select * from jxhx_ecms_news where classid = ".$bqr[classid]."  and  titlepic!=' ' and isgood=1 order by newstime desc limit 2");
$commbookurl=sys_ReturnBqTitleLink($commbook);
 while($r=$empire->fetch($commbook)) {
    ?>
          <li><a href="<?=sys_ReturnBqTitleLink($r)?>"><img src="<?=$r[titlepic]?>"><span>
            <?=$r[title]?>
            </span></a></li>
          <?php
     }
 ?>
        </ul>
      </div>
      <ul class="newslist">
        <?php
//取得该分类下的最新数据
 
    $newbook=$empire->query("select * from  jxhx_ecms_news  where classid =".$bqr[classid]." order by newstime desc limit 5");
    
    while($r=$empire->fetch($newbook)) {
    ?>
        <li><i></i><a href="<?=sys_ReturnBqTitleLink($r)?>" title="<?=$r[title]?>">
          <?=esub($r[title],60,'...')?>
          </a>
          <p>
            <?=$r[smalltext]?>
          </p>
        </li>
        <?php
     }
     //显示5条
    ?>
      </ul>
    </div>
    [/e:loop] </div>
</div>
