帝国CMS二次开发tags标签增加封面图片方法
1、首先帝国CMS tags默认的字段肯定是没有这些字段的，所以我们就手动加几个字段。
添加tagimg，path两个字段，一个为封面图，一个是地址
类型都是：VARCHAR，长度：200，整理：utf8_general_ci
2、修改后台tags添加页面
打开/e/admin/tags/AddTags.php
里面的表单替换成代码
<?=$ecms_hashur['form']?>
<?=$postword?>
所属分类:
不分类 <?=$cs?>
TAG名称:
(最多20个字)
网页标题:
(最多60个字)
网页关键词:
(最多100个字)
网页描述:
<?=$r[tagdes]?>(最多255个字)
TAG文件名:
TAG缩略图
3、修改数据提交，修改
打开/e/admin/tags/ListTags.php
//增加TAGSfunction AddTags($add,$userid,$username){ global $empire,$dbtbpre; $tagname=RepPostVar($add['tagname']); $cid=(int)$add['cid']; if(!$tagname) { printerror("EmptyTagname","history.go(-1)"); } //验证权限 CheckLevel($userid,$username,$classid,"tags"); $ecms_fclast=time(); $add['tagtitle']=hRepPostStr(RepPhpAspJs电脑端ode($add['tagtitle'])); $add['tagkey']=hRepPostStr(RepPhpAspJs电脑端ode($add['tagkey'])); $add['tagdes']=hRepPostStr(RepPhpAspJs电脑端ode($add['tagdes'])); $path=$add['path']; $tagimg=$add['tagimg']; $num=$empire->gettotal("select count(*) as total from {$dbtbpre}enewstags where tagname='$tagname' limit 1"); if($num) { printerror("HaveTagname","history.go(-1)"); } $sql=$empire->query("insert into {$dbtbpre}enewstags(tagname,num,isgood,cid,tagtitle,tagkey,tagdes,fclast,path,tagimg) values('$tagname',0,0,'$cid','$add[tagtitle]','$add[tagkey]','$add[tagdes]','$ecms_fclast','$add[path]','$add[tagimg]');"); if($sql) { $tagid=$empire->lastid(); //操作日志 insert_dolog("tagid=$tagid&tagname=$tagname"); printerror("AddTagsSuccess","AddTags.php?enews=AddTags".hReturnEcmsHashStrHref2(0)); } else { printerror("DbError","history.go(-1)"); }} //修改TAGSfunction EditTags($add,$userid,$username){ global $empire,$dbtbpre; $tagid=(int)$add['tagid']; $tagname=RepPostVar($add['tagname']); $cid=(int)$add['cid']; $path=$add['path']; $tagimg=$add['tagimg']; if(!$tagid||!$tagname) { printerror("EmptyTagname","history.go(-1)"); } //验证权限 CheckLevel($userid,$username,$classid,"tags"); $ecms_fclast=time(); $add['tagtitle']=hRepPostStr(RepPhpAspJs电脑端ode($add['tagtitle'])); $add['tagkey']=hRepPostStr(RepPhpAspJs电脑端ode($add['tagkey'])); $add['tagdes']=hRepPostStr(RepPhpAspJs电脑端ode($add['tagdes'])); $num=$empire->gettotal("select count(*) as total from {$dbtbpre}enewstags where tagname='$tagname' and tagid<>$tagid limit 1"); if($num) { printerror("HaveTagname","history.go(-1)"); } $sql=$empire->query("update {$dbtbpre}enewstags set tagname='$tagname',cid='$cid',tagtitle='$add[tagtitle]',tagkey='$add[tagkey]',tagdes='$add[tagdes]',fclast='$ecms_fclast',path='$path',tagimg='$tagimg' where tagid='$tagid'"); if($sql) { //操作日志 insert_dolog("tagid=$tagid&tagname=$tagname"); printerror("EditTagsSuccess","ListTags.php?cid=$add[fcid]".hReturnEcmsHashStrHref2(0)); } else { printerror("DbError","history.go(-1)"); }}
