帝国cms如何调用关键词相同的文章呢？

根据关键字相关的方式调用，代码如下

1. <?php
2. if ($navinfor['keyboard'])
3. {
4. $c_key=explode(',',$navinfor['keyboard']);
5. $count=count($c_key);
6. for($i=0;$i<$count;$i++)
7. {
8. if($i==0)
9. {
10. $or='';
11. }
12. else
13. {
14. $or=' or ';
15. }
16. $repadd.=$or."keyboard like '%".$c_key[$i]."%'";
17. }
18. $r=$empire->fetch1("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$repadd." order by newstime desc limit 1");
19. if($r[title])
20. {
21. $mesql=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news where id<>".$navinfor['id']." and ".$repadd." order by newstime desc limit 10");
22. while($or=$empire->fetch($mesql))
23. {
24. $newstime=date('Y-m-d',$or[newstime]);
25. ?>
26. <li><a href="<?=$or[titleurl]?>"><?=$or[title]?></a><span><?=$newstime?></span></li>
27. <?
28. }
29. }
30. else
31. {
33. $mesql2=$empire->query("select * from {$dbtbpre}ecms_news where id<>".$navinfor['id']." order by rand() desc limit 10");
34. while($r2=$empire->fetch($mesql2))
35. {
36. $newstime=date('Y-m-d',$o2[newstime]);
37. ?>
38. <li><a href="<?=$r2[titleurl]?>"><?=$r2[title]?></a><span><?=$newstime?></span></li>
39. <?
40. }
41. }
42. }
43. else
44. {
45. $mesql2=$empire->query("select titleurl,title,newstime from {$dbtbpre}ecms_news order by rand() desc limit 10");
46. while($r2=$empire->fetch($mesql2))
47. {
48. $newstime=date('Y-m-d',$r2[newstime]);
49. ?>
50. <li><a href="<?=$r2[titleurl]?>"><?=$r2[title]?></a><span><?=$newstime?></span></li>
51. <?
52. }
53. }
54. ?>

注释：我们不填写关键字的时候，随机调用文章，如果我们添加了关键字，没有相关的文章，也是随机调用文章
