自定义方法修改文件：include/extend.func.php
## 一、栏目增加自定义字段
### 1.增加栏目缩略图、栏目英文名
~~~
//字段名：arcpic，english
~~~
**a. 文件：catalog_add.htm**
~~~
<tr>
<td class='bline' height="26" style="padding-left:10px;">栏目图片：</td>
<td class='bline'> <input name="arcpic" type="text" value="<?php echo $arcpic?>" class="pubinputs" style="width:300px" />
<input type="button" name="set3" value="浏览... " class="coolbg np" style="width:60px" onClick="SelectImage('form1.arcpic','small');" />
</td>
</tr>
<tr>
<td class='bline' height="26" style="padding-left:10px;"><font>英文名：</font></td>
<td class='bline'><input name="english" type="text" id="english" size="30" class="iptxt" /></td>
</tr>
~~~
**b. 文件：catalog_edit.htm**
~~~
<tr>
<td height="26">栏目图片：</td>
<td> <input name="arcpic" type="text" value="<?php echo $myrow['arcpic']?>" class="pubinputs" style="width:300px" />
<input type="button" name="set3" value="浏览... "class="coolbg np" style="width:60px" onClick="SelectImage('form1.arcpic','small');" />
</td>
</tr>
<tr>
<td class='bline' height="26"><font color='red'>英文名：</font></td>
<td class='bline'><input name="english" type="text" id="english" size="30" value="<?php echo $myrow['english']?>" class="iptxt" /></td>
</tr>
~~~
**c.以上2个文件需要增加js文件**
~~~
<script language="javascript" src="../include/dedeajax2.js"></script>
<script language='javascript' src='js/main.js'></script>
~~~
**e. mysql运行字段添加到数据库**
~~~
ALTER TABLE `dede_arctype` ADD `arcpic` VARCHAR(128);
ALTER TABLE `dede_arctype` ADD `english` VARCHAR(64);
~~~
## 二、自定义方法
### 1、获取顶级栏目名称
~~~
function GetTopTypename($id)
{
global $dsql;
$row = $dsql->GetOne("SELECT typename,topid FROM `#@__arctype` WHERE id= $id");
if ($row['topid'] == '0')
{
return $row['typename'];
}
else
{
$row1 = $dsql->GetOne("SELECT typename FROM `#@__arctype` WHERE id= $row[topid]");
return $row1['typename'];
}
}
~~~
调用方式
~~~
{dede:field name='typeid' function="GetTopTypename(@me)" /}
~~~
### 2、获取顶级栏目英文名称
~~~
function GetTopEnname($id)
{
global $dsql;
$row = $dsql->GetOne("SELECT english,topid FROM `#@__arctype` WHERE id= $id");
if ($row['topid'] == '0')
{
return $row['english'];
}
else
{
$row1 = $dsql->GetOne("SELECT english FROM `#@__arctype` WHERE id= $row[topid]");
return $row1['english'];
}
}
~~~
调用方式
~~~
{dede:field name='typeid' function="GetTopEnname(@me)" /}
~~~
