DedeCMS织梦单独调用上下篇文章链接和标题

PetitQ DedeCMS织梦 2018-11-07 4.40K 0 3

织梦默认的上一篇,下一篇调用标签是：{dede:prenext get='pre'/} {dede:prenext get='next'/},有的情况加我们只想要单独的链接和标题那该怎么办呢！接下来交大家方法.

第一步：

打开/include/arc.archives.class.php 文件找到：

也想出现在这里？联系我们吧

```
/**
```

     *  获取上一篇，下一篇链接

```
     *
```
```
     * @access    public
```

     * @param     string  $gtype  获取类型

     *                    pre:上一篇  preimg:上一篇图片  next:下一篇  nextimg:下一篇图片

```
     * @return    string
```
```
     */
```

　　大概在 795 行左右

替换代码如下：

```
/**
```

     *  获取上一篇，下一篇链接

```
     *
```
```
     * @access    public
```

     * @param     string  $gtype  获取类型

     *                    pre:上一篇  preimg:上一篇图片  next:下一篇  nextimg:下一篇图片

```
     * @return    string
```
```
     */
```
```
    function GetPreNext($gtype='')
```
```
    {
```
```
        $rs = '';
```
```
        if(count($this->PreNext)<2)
```
```
        {
```
```
            $aid = $this->ArcID;
```

            $preR =  $this->dsql->GetOne("Select id From `dede_arctiny` where id<$aid And arcrank>-1 And typeid='{$this->Fields['typeid']}' order by id desc");

            $nextR = $this->dsql->GetOne("Select id From `dede_arctiny` where id>$aid And arcrank>-1 And typeid='{$this->Fields['typeid']}' order by id asc");

            $next = (is_array($nextR) ? " where arc.id={$nextR['id']} " : ' where 1>2 ');

            $pre = (is_array($preR) ? " where arc.id={$preR['id']} " : ' where 1>2 ');

            }

```
```
        else
```
```
        {
```

            $rs =  $this->PreNext['pre']." &nbsp; ".$this->PreNext['next'];

```
        }
```
```
        return $rs;
```
```
    }
```

第二步：

文件替换好了 ,那就可以调用的了,调用标签如下：

　　下一篇链接：{dede:prenext get='preurl'/} 上一篇链接：{dede:prenext get='nexturl'/}

　　下一篇标题：{dede:prenext get='prename'/} 上一篇链接：{dede:prenext get='nextname'/}

注：因为调用顺序是按发布时间更新的,有人问为啥下一篇链接用 preurl,这个不做解释了,自己调用一下就明白了！
