分页和搜索引擎

Question

我使用分页脚本查看搜索结果， 但这个当我点击下一页时打破了结果，因为没有在另一页上传递变量。

我在页面“index.php”中创建搜索表单。 和“search.php”查看结果。

请修改我的代码！ 非常感谢

（对不起，坏的坏的英语不好（我不使用翻译））

“的index.php”

我想你想说的是，搜索字词没有正确传递？

从我在代码中可以看到的，变量$cerca是搜索项。

你可以使用的$_GET['cerca']代替$_REQUEST

而且更重要的是，我不认为你可以在查询做到这一点：

$query = "SELECT COUNT(*) as num FROM $tableName WHERE Nome LIKE '%$cerca%' 

你应该分裂了LIKE部分，如本

$query = "SELECT COUNT(*) as num FROM $tableName WHERE Nome LIKE '%" . $cerca . "%' 

这样做你所做的所有不同的时间LIKE

或者我认为这是你问的是什么...
