以下是具體實現過程：
以下代碼放到/e/class/userfun.php里！
<?php function user_otherlink($limit=5){ global $dbtbpre,$empire,$navinfor,$class_r; if($navinfor[infotags]){ $classid=(int)$classid; $limit=(int)$limit; $tbname=$class_r[$navinfor[classid]][tbname]; $tagarr=explode(",",$navinfor[infotags]); $arr=array(); $num=ceil($limit/count($tagarr)); foreach($tagarr as $k=>$v){ if(count($tagarr)==$k+1){ $num=$limit-count($arr); }else{ if($i<$num){ $num=ceil(($limit-count($arr))/count($tagarr)); } } $t=$empire->fetch1("select tagid,num from {$dbtbpre}enewstags where tagname='$v'"); if($t[tagid]){ $sql=$empire->query("select id from {$dbtbpre}enewstagsdata where tagid=$t[tagid]"); $i=0; while($s=$empire->fetch($sql)){ if(in_array($s[id],$arr)||$s[id]==$navinfor[id]){ continue; }else{ $arr[]=$s[id]; $i++; } if($i==$num){ break; } if(count($arr)==$limit){ break 2; } } if($t[num]>$num){ $linshi=$t[tagid]; } } } if(count($arr)>0){ $inid=implode(",",$arr); if(count($arr)<$limit&&$linshi){ $sql=$empire->query("select id from {$dbtbpre}enewstagsdata where tagid=$linshi and id not in($inid)"); while($s=$empire->fetch($sql)){ $arr[]=$s[id]; if(count($arr)==$limit){ break; } } } $inid=implode(",",$arr); $str=""; $news=$empire->query("select id,title,titleurl,titlepic from {$dbtbpre}ecms_{$tbname} where id in($inid)"); while($n=$empire->fetch($news)){ $str.='<li><a href="'.$n[titleurl].'">'.$n[title].'</a></li>'; } } return $str; } } ?> |
