下拉菜单不起作用（不同的用户任务）

Question

我制作了一个系统，其中用户有不同的任务。第二个下拉菜单有问题。只有第一个下拉菜单功能。我通过循环分隔查询，但它仍然不起作用。我能做些什么来解决它？

$CurrentID = $_SESSION['username'];
$CurrentID = strtoupper($CurrentID);

$sql = "SELECT * FROM task WHERE user_id=?"
$params = array($CurrentID);
$options = array("Scrollable" => SQLSRV_CURSOR_KEYSET);
$query = sqlsrv_query($conn, $sql, $params, $options);

<li>
    <a href="javascript:;" data-toggle="collapse" data-target="#sro"><i class="fa fa-circle-o-notch"></i> SRO <i class="fa fa-fw fa-caret-down"></i></a>
    <ul id="sro" class="collapse">   
        <?php
            while ($result = sqlsrv_fetch_array($query, SQLSRV_FETCH_ASSOC)) { //LOPPING FOR SRO
                //$url_id_f = $result[3]; //get url_id
                if ($result['url_id'] == '5') {
                    echo "<p><a href='add_sro.php'><i class='fa fa-plus-square-o' aria-hidden='true'></i> Add New SRO</a></p> ";
                }

                if ($result['url_id'] == '30') {
                    echo '<p><a href="edit_sro.php"><i class="fa fa-pencil-square-o" aria-hidden="true"></i> Edit Service Request Order</a></p> ';
                }

                if ($result['url_id'] == '48') {

                }
            }
            ?>
    </ul>

            }

            }

Answer 1

一旦执行结果，您的sqlsrv_fetch_array 将返回 null。所以第二次你不能从中获取数据。

如果您想第二次循环，那么您必须再次执行查询，或者您可以先将数据存储在数组中，然后多次遍历数组。

$CurrentID = $_SESSION['username'];
$CurrentID = strtoupper($CurrentID);

$sql = "SELECT * FROM task WHERE user_id=?"
$params = array($CurrentID);
$options = array("Scrollable" => SQLSRV_CURSOR_KEYSET);
$query = sqlsrv_query($conn, $sql, $params, $options);

<li>
    <a href="javascript:;" data-toggle="collapse" data-target="#sro"><i class="fa fa-circle-o-notch"></i> SRO <i class="fa fa-fw fa-caret-down"></i></a>
    <ul id="sro" class="collapse">   
        <?php
            while ($result = sqlsrv_fetch_array($query, SQLSRV_FETCH_ASSOC)) { //LOPPING FOR SRO
                //$url_id_f = $result[3]; //get url_id
                if ($result['url_id'] == '5') {
                    echo "<p><a href='add_sro.php'><i class='fa fa-plus-square-o' aria-hidden='true'></i> Add New SRO</a></p> ";
                }

                if ($result['url_id'] == '30') {
                    echo '<p><a href="edit_sro.php"><i class="fa fa-pencil-square-o" aria-hidden="true"></i> Edit Service Request Order</a></p> ';
                }

                if ($result['url_id'] == '48') {

                }

                if ($result['url_id'] == '7') {
                    echo '<p><a href="approval_cbw.php"><i class="fa fa-check-circle" aria-hidden="true"></i> Approval by Client Business Owner</a></p> ';
