如何在switch语句内里面使用分页功能?
我创建了一个表单
<form action = "query.php" method = "post" enctype = "multipart/form-data"><br /> 选择查找类型: <br /><br /> <select name = "query"><br /> <option value = "name">name</option><br /> <option value = "address">address/option><br /> </select><br /> <br /><br /> 输入查找内容: <br /><br /> <input type = "text" name = "query_text" maxlength = "17"/><br /> <input type = "submit" value = "查找" /><br /></form><br />
在query.php页面选择的结构是:
switch ($_POST['query']){
case "name":
此处查找数据库,并显示出来;
case "address":
此处查找数据库,并显示出来;
}
如何在[case "name"]与[case "address"]下查找数据库后显示加入分页功能啊?
由于分页浏览时,需要$_GET['page']来传递页数,但query.php页也有$_POST变量, 请问如何处理?麻烦指教
------解决方案--------------------可以在query.php写个函数,把页数和查找类型作为参数传给函数。函数根据查找类型和页数查找每页的数据。然后在case后调用,或者在$_GET后调用。也可以在其他的php文件里写查找数据的函数,include进来,调用函数。$_POST不影响$_GET吧,你post过来肯定显示的是第一页把,可以把函数参数默认为第一页
