【问题描述】：
我想编写一个带有搜索排序和分页的表格。 这三个操作都应该相互连接。 我写了一个用于搜索和分页的代码 但我无法在其中添加排序逻辑 谁能指导一个简单的方法来执行这个 这是我的代码
<?php
include 'dbconfig.php';
$records_per_page=10;
$name = "";
$email= "";
$queryCondition = "";
if(!empty($_POST["search"])) {
foreach($_POST["search"] as $k=>$v){
if(!empty($v)) {
$queryCases = array("name","email");
if(in_array($k,$queryCases)) {
if(!empty($queryCondition)) {
$queryCondition .= " AND ";
} else {
$queryCondition .= " WHERE ";
}
}
switch($k) {
case "name":
$name = $v;
$queryCondition .= "username LIKE '" . $v . "%'";
break;
case "email":
$email = $v;
$queryCondition .= "user_email LIKE '" . $v . "%'";
break;
}
}
}
}
//if(isset($_POST["order"]))
//{
// $order=$_POST["order"];
//
//}
// else{
// $order="user_id";
//}
//if(isset($_POST["by"])){
// $by=$_POST["by"];
//if($by=="asc" & !isset($_POST["page"])){
// $by="desc";
//
// }else if($by=="desc" & !isset($_POST["page"]))
// {
//
// $by="asc";
//
// }
// else
// {
// $by=$_POST["by"];
// }
//}
//else
//{
// $by="asc";
//}
$orderby = " ORDER BY $order $by";
$sql = "SELECT * FROM tbl_register " . $queryCondition;
$href = 'demo2.php';
$perPage = 10;
$page = 1;
if(isset($_POST['page'])){
$page = $_POST['page'];
}
$start = ($page-1)*$perPage;
if($start < 0) $start = 0;
$query = $sql . $orderby . " limit " . $start . "," . $perPage;
// $result = $db_handle->runQuery($query);
$result = mysql_query($query);
while($row=mysql_fetch_array($result)) {
$resultset[] = $row;
}
if(!empty($resultset)) {
$resultset["perpage"] = showperpage($sql, $perPage, $href,$order,$by);
}

background:none;
cursor:pointer;
color:#0000EE;
padding:0;

}
</style>
当用户点击表头时，我希望如何在其中添加排序逻辑，它应该在 asc n desc 和每个表头之间切换。
