我是俄语，很抱歉，我的英语不太好。
我的问题是关于Joomla的分页。 在我们的任务exemple.php中，我们只有一个函数display（）;做分页 - 很容易。
但我有一个真正的问题。在我的页面示例我有搜索表单，我需要分页搜索结果。当我开始搜索某些东西时，我看到了我的搜索表单，搜索结果，页面页脚上的分页，但是当我点击2,3 .....页时，它们打开时没有任何结果 - 只有搜索表单。在我的任务exemple.php中我有4个函数。请帮我在所有分页页面上进行分页工作。
谢谢！

女贞，
你有愚蠢的问题。您原始查询生成有限数量的记录选择。
SELECT ... FROM ... WHERE ... LIMIT $limitstart, $limit
然后你使用"SELECT FOUND_ROWS();"这将是$ limit，所以实际上你只有1页的分页。
您的查询需要像这样：
SELECT ... FROM ... WHERE ... LIMIT $limitstart, $limit Uda4i！

joomla分页的简单解决方案，请查看
...templates/protostar/html/pagination.php并将其粘贴到您的
模板html文件夹...templates/mytemplate/html/pagination.php，
根据您的喜好编辑样式
