調(diào)用指定欄目中所有數(shù)據(jù)包含的TAG或者當前欄目中所有數(shù)據(jù)包含的TAG，使用方法即可實現(xiàn)
方式1

[e:loop={"select DISTINCT([!db.pre!]enewstags.tagname),[!db.pre!]enewstags.tagid,[!db.pre!]enewstags.num from [!db.pre!]enewstags inner join [!db.pre!]enewstagsdata on [!db.pre!]enewstags.tagid = [!db.pre!]enewstagsdata.tagid where [!db.pre!]enewstagsdata.classid = 3 order by [!db.pre!]enewstags.num DESC limit 30",0,24}]
<a href='<?=$public_r['newsurl']?>e/tags/?tagname=<?=$bqr['tagname']?>' title='<?=$bqr['num']?>個'><?=$bqr['tagname']?>(<?=$bqr['num']?>)</a>
[/e:loop]

方式2（和上面的相同，只是sql格式有稍微不同）

[e:loop={"select a.tagname,a.num,b.tagid from [!db.pre!]enewstags a,[!db.pre!]enewstagsdata b where a.tagid=b.tagid and classid=3 group by tagid order by num desclimit 40",40,24,0}]
<a href='<?=$public_r['newsurl']?>e/tags/?tagname=<?=$bqr['tagname']?>' title='<?=$bqr['num']?>個'><?=$bqr['tagname']?>(<?=$bqr['num']?>)</a>
[/e:loop]

方式3（和上面的相同，只是sql格式有稍微不同）

[e:loop={"select a.*,b.* from [!db.pre!]enewstags a,[!db.pre!]enewstagsdata b where a.tagid=b.tagid and classid=3 group by b.tagid order by a.num desclimit 40",40,24,0}]
<a href='<?=$public_r['newsurl']?>e/tags/?tagname=<?=$bqr['tagname']?>' title='<?=$bqr['num']?>個'><?=$bqr['tagname']?>(<?=$bqr['num']?>)</a>
[/e:loop]

方式4（和上面的相同，只是sql格式有稍微不同）

[e:loop={"select a.*,b.* from [!db.pre!]enewstags a LEFT JOIN [!db.pre!]enewstagsdata b ON a.tagid=b.tagid where classid=3 group by b.tagid order by a.num desc limit 100",0,24,0}]
<a href='<?=$public_r['newsurl']?>e/tags/?tagname=<?=$bqr['tagname']?>' title='<?=$bqr['num']?>個'><?=$bqr['tagname']?>(<?=$bqr['num']?>)</a>
[/e:loop]

注釋：classid = 3 為欄目ID（新聞ID）必須為終極欄目
1、上面的為調(diào)用單個欄目
2、多個欄目時，修改“classid = 3”為 classid in(4,5,6,7)
3、調(diào)用當前欄目（列表、內(nèi)容通用）：把 “ classid = 3”替換為“ classid='$GLOBALS[navclassid]' ”
