帝国CMS如何给tags增加封面图片

教程步骤：

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">
  <?=$ecms_hashur['form']?>
    <tr class="header"> 
      <td  colspan="2"><?=$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="<?=$fcid?>"> </td>
    </tr>
        <tr bgcolor="#FFFFFF"> 
      <td >所属分类:</td>
      <td ><select name="cid" id="cid">
          <option value="0">不分类</option>
          <?=$cs?>
        </select> 
        <input type="button" name="Submit62223" value="管理分类" onClick="window.open('TagsClass.php<?=$ecms_hashur['whehref']?>');"></td>
    </tr>
    <tr bgcolor="#FFFFFF"> 
      <td width="18%" >TAG名称:</td>
      <td width="82%" > <input name="tagname" type="text" id="tagname" value="<?=$r[tagname]?>" size="42">
        <font color="#666666">(最多20个字)</font> </td>
    </tr>
    <tr bgcolor="#FFFFFF">
      <td >网页标题:</td>
      <td ><input name="tagtitle" type="text" id="tagtitle" value="<?=ehtmlspecialchars($r[tagtitle])?>" size="42">
      <font color="#666666">(最多60个字)</font></td>
    </tr>
    <tr bgcolor="#FFFFFF">
      <td >网页关键词:</td>
      <td ><input name="tagkey" type="text" id="tagkey" value="<?=ehtmlspecialchars($r[tagkey])?>" size="42">
      <font color="#666666">(最多100个字)</font></td>
    </tr>
    <tr bgcolor="#FFFFFF">
      <td >网页描述:</td>
      <td ><textarea name="tagdes" cols="70" rows="8" id="tagdes"><?=$r[tagdes]?></textarea>
      <font color="#666666">(最多255个字)</font></td>
    </tr>
    <tr bgcolor="#FFFFFF"> 
      <td width="18%" >TAG文件名:</td>
      <td width="82%" > <input name="path" type="text" id="path" value="<?=$r[path]?>" size="42"> 
      </td>
    </tr>
    <tr bgcolor="#FFFFFF"> 
          <td >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"   border="0" align="absbottom"></a></td>
        </tr>
    <tr bgcolor="#FFFFFF"> 
      <td >&nbsp;</td>
      <td > <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)");
    }
}
