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><!--tab_box end-->
