如何在 PHP、SQLSRV 中对单击标题 ASC/DESC 上的表进行排序答案

【问题标题】：How to sort table on click header ASC/DESC in PHP, SQLSRV如何在 PHP、SQLSRV 中对单击标题 ASC/DESC 上的表进行排序

【问题描述】：

我们想按标题[JobTitle] 和[Status] 对我们的SQLSRV/PHP 表进行排序，我们尝试使用$_GET 选项，但我们无法按照我们的表代码对其进行管理。我们无法让$_GET 解决方案发挥作用。

<body>
<div class="table-title">
    <h3>Test table</h3>
<?php
   ini_set('display_errors', 1);
   error_reporting(~0);

    $serverName = "localhost";
    $userName = "username";
    $userPassword = "password";
    $dbName = "AdWorks";

   $connectionInfo = array("Database"=>$dbName, "UID"=>$userName, "PWD"=>$userPassword, "MultipleActiveResultSets"=>true);

   $conn = sqlsrv_connect( $serverName, $connectionInfo);

   if( $conn === false ) {
      die( print_r( sqlsrv_errors(), true));
   }

?>
<form action="list.php" method="POST">
<select name="RegSelect"><option> Choose </option>
<?php

$sql = "SELECT DISTINCT CountryRegionName FROM dbTest ORDER BY CountryRegionName";
$resultRg = sqlsrv_query($conn,$sql) or die("Couldn't execut query");
while ($data=sqlsrv_fetch_array($resultRg, SQLSRV_FETCH_ASSOC)){
    echo '<option value="'.$data['CountryRegionName'].'">';
    echo $data['CountryRegionName']; 
    echo "</option>";
}

if(empty($_POST['RegSelect'])){
    $_SESSION['tower'] = '';
} else {
    $stmt = "SELECT BusinessEntityID, FirstName, LastName, JobTitle, PhoneNumber, PhoneNumberType, EmailAddress, AddressLine1, City, PostalCode, CountryRegionName, Status FROM dbTest WHERE CountryRegionName = '".$_POST['RegSelect']."'";

    $qry = sqlsrv_query($conn, $stmt);
}
?>
<input type="submit" value="Select Tower">

while($result = sqlsrv_fetch_array($qry, SQLSRV_FETCH_ASSOC)){
    //print_r($result);

sqlsrv_close($conn);

【问题讨论】：

不了解您的要求
我们希望当您点击标题 [JobTitle] 或 [Status] 时，表格按 [JobTitle] 或 [Status] ASC 或 DESC 排序.
你想用 PHP GET 请求来做吗？
如果可以，为什么不呢，但也欢迎任何其他解决方案
找到了这段代码，但也不起作用：if(isset($by) and $by=="DESC"){ $by="ASC"; }else{ $by="DESC"; } 在标题上<th width="30"><a href='list.php?by=<?=$by; ?>'><div align="center">Status </div></a></th>

【解决方案1】：

在了解了它的工作原理之后，我找到了使用 JQuery Tablesorter 的解决方案。
