最终效果
帝国cms二次开发tags增加封面图片步骤
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
里面的表单替换成如下代码
<form name="form1" method="post" action="ListTags.php">
<table width="100%" border="0" align="center" cellpadding="3" cellspacing="1" class="tableborder">
<?=$ecms_hashur['form']?>
<tr class="header">
<td height="25" colspan="2"><?=$postword?>
<input name="enews" type="hidden" id="enews" value="<?=$enews?>"> <input name="tagid" type="hidden" id="tagid" value="<?=$tagid?>">
<input name="fcid" type="hidden" id="fcid" value="<?=$fcid?>"> </td>
</tr>
<tr bgcolor="#FFFFFF">
<td height="25">所属分类:</td>
<td height="25"><select name="cid" id="cid">
<option value="0">不分类</option>
<?=$cs?>
</select>
<input type="button" name="Submit62223" value="管理分类" onClick="window.open('TagsClass.php<?=$ecms_hashur['whehref']?>');"></td>
</tr>
<tr bgcolor="#FFFFFF">
<td width="18%" height="25">TAG名称:</td>
<td width="82%" height="25"> <input name="tagname" type="text" id="tagname" value="<?=$r[tagname]?>" size="42">
<font color="#666666">(最多20个字)</font> </td>
</tr>
<tr bgcolor="#FFFFFF">
<td height="25">网页标题:</td>
<td height="25"><input name="tagtitle" type="text" id="tagtitle" value="<?=ehtmlspecialchars($r[tagtitle])?>" size="42">
<font color="#666666">(最多60个字)</font></td>
</tr>
<tr bgcolor="#FFFFFF">
<td height="25">网页关键词:</td>
<td height="25"><input name="tagkey" type="text" id="tagkey" value="<?=ehtmlspecialchars($r[tagkey])?>" size="42">
<font color="#666666">(最多100个字)</font></td>
</tr>
<tr bgcolor="#FFFFFF">
<td height="25">网页描述:</td>
<td height="25"><textarea name="tagdes" cols="70" rows="8" id="tagdes"><?=$r[tagdes]?></textarea>
<font color="#666666">(最多255个字)</font></td>
</tr>
<tr bgcolor="#FFFFFF">
<td width="18%" height="25">TAG文件名:</td>
<td width="82%" height="25"> <input name="path" type="text" id="path" value="<?=$r[path]?>" size="42">
</td>
</tr>
<tr bgcolor="#FFFFFF">
<td height="25">TAG缩略图</td>
<td><input name="tagimg" type="text" id="tagimg" value="<?=$r[tagimg]?>" size="38">
<a onClick="window.open('../ecmseditor/FileMain.php<?=$ecms_hashur['whehref']?>&modtype=1&type=1&classid=&doing=2&field=tagimg&filepass=2&sinfo=1','','width=700,height=550,scrollbars=yes');" title="选择已上传的图片"><img src="../../data/images/changeimg.gif" width="22" height="22" border="0" align="absbottom"></a></td>
</tr>
<tr bgcolor="#FFFFFF">
<td height="25"> </td>
<td height="25"> <input type="submit" name="Submit" value="提交"> <input type="reset" name="Submit2" value="重置"></td>
</tr>
</table>
</form>3、修改数据提交，修改
打开/e/admin/tags/ListTags.php
//增加TAGS
function 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();
$add['tagtitle']=hRepPostStr(RepPhpAspJspcode($add['tagtitle']));
$add['tagkey']=hRepPostStr(RepPhpAspJspcode($add['tagkey']));
$add['tagdes']=hRepPostStr(RepPhpAspJspcode($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TAGS
function 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();
$add['tagtitle']=hRepPostStr(RepPhpAspJspcode($add['tagtitle']));
$add['tagkey']=hRepPostStr(RepPhpAspJspcode($add['tagkey']));
$add['tagdes']=hRepPostStr(RepPhpAspJspcode($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)");
}
