精華 當帝國PHP系統CMS欄目沒有設置封面圖片，怎樣顯示指定圖片？

                        <p>靈動標簽調用的標簽內的模版顯示了欄目縮放圖</p>

當欄目沒有欄目縮放圖時，則顯示指定圖片：

[e:loop={"select classid, classname,classimg,classpath from '[!db.pre!]enewsclass' where bclassid='$bclassid' order by 'classid' desc ",7,24,0}] <a href="http://www.viagraonlinego.com/<?=$public_r[newsurl]?><?=$bqr[classpath]?>">
<img src="http://www.viagraonlinego.com/<?=$bqr[classimg]?$bqr[classimg]:'/e/data/images/notimg.gif'?>" ></a>  <a href="http://www.viagraonlinego.com/<?=$public_r[newsurl]?><?=$bqr[classpath]?>"><?=$bqr[classname]?></a> [/e:loop]

[e:loop={"select classimg from phome_enewsclass where classid='$GLOBALS[navclassid]'",1,24,0}]<?=$bqr[classimg]?$bqr[classimg]:'/e/data/images/notimg.gif'?>[/e:loop]

[e:loop={"select classimg from phome_enewsclass where classid='$GLOBALS[navclassid]'",1,24,0}]<img src="http://www.viagraonlinego.com/<?=$bqr[classimg]?>" alt="[!---class.name--]">[/e:loop]
