Question

你能帮我解决一下如何从MySQL表中对数据进行排序吗？

我想通过使用表头进行排序：

<?php
    if(isset($_POST['search'])) {
        $valueTosearch = $_POST['searchvalue'];
        $query = "SELECT * FROM `admin` WHERE CONCAT(`id`, `name`, `gender`, `user_group`, `date_registered`) LIKE '%".$valueTosearch."%'";
        $search_result = filterTable($query);
    } else {
        $query = "SELECT * FROM `admin`";
        $search_result = filterTable($query);
    }

    function filterTable($query)
    {
        include('config/dbconnect.php');
        $filter_result = mysqli_query($con, $query);
        return $filter_result;
    }
?>

<form method='post' action=''>
    <div><input type = 'text' name = 'searchvalue' placeholder="search by name">
        <span>
            <div style='margin-bottom:3px; margin-top:3px'>
                <input id='gradient' class='search-btn' type = 'hidden' name = 'search' value = 'search'>
            </div>
        </span>
        <div style="height: auto">
            <table id='responsive_table'>
                <thead>
                    <tr>
                        <th scope="col"><a href="sort">name</a></th>
                        <th scope="col"><a href="sort">sex</a></th>
                        <th scope="col"><a href="sort">user group</a></th>
                        <th scope="col"><a href="sort">date register</a></th>
                    </tr>
                </thead>
                <?php while($row = mysqli_fetch_array($search_result)): ?>
                <tbody>
                    <tr>
                        <td scope="row" data-label='name'><?php echo $row['name']; ?></td>
                        <td data-label='sex'><?php echo $row['gender']; ?></td>
                        <td data-label='user group'><?php echo $row['user_group']; ?></td>
                        <td data-label='date register'><?php echo $row['date_registered']; ?></td>
                    </tr>
                </tbody>
                <?php endwhile; ?>
            </table>
    </div>
</form>

Answer 1

您可以按如下方式修改查询以进行排序：

sql > select * from <table name> order by <column name>;

默认排序是升序，其他用于降序，你可以这样做

sql > select * from <table name> order by <column name> desc;

Answer 2

为什么不使用 order by 子句：

SELECT * FROM table ORDER BY列;

Order By Reference

Answer 3

如果您可以使用JQuery，它非常简单，您只需要添加以下JavaScript代码：

$( document ).ready(function() {
    $("#responsive_table").DataTable({
      ordering: true,
      searching: true
    });
});

有关完整示例，请参阅以下代码：
