dedecms动态设置相关文章

    dedecms动态设置相关文章,这个功能是十分需要的，我们可以通过对dedecms的文章增加相关文章的id字段，在录入文章和编辑文章的时候，可以修改这个字段的值，从而达到后台动态控制相关文章的文章id,然后自己编写dedecms标签realarticle来实现动态对dedecms相关文章的功能调用实现。

1:alter table dede_archives add column reaid varchar(64) not null default ''
2:后台article_edit.html article_add.html增加以下代码
<tr>
      <td height="24" class="bline">
          <table width="800" border="0" cellspacing="0" cellpadding="0">
          <tr>
            <td width="90">&nbsp;相关文章：</td>
            <td>
           <span id='typeid2ct'></span>
           <input type='text' name='reaid' id='reaid' value='<?php echo ($arcRow['reaid']=='0' ? '' : $arcRow['reaid']); ?>' style='width:200px;' />
           录入ID，用逗号隔开(1,2,3)
                 </td>
          </tr>
        </table>
      </td>
    </tr>

3:article_add.php article_edit.php

reaid='$reaid'修改这个字段

4:调用
{dede:realarticle limit=3}
<a href=[field:arcurl/]>[field:title/]</a><br>
{/dede:realarticle}

5:标签


<?php
