下拉菜單不起作用（不同的用戶任務）

Question

我製作了一個系統，用戶有不同的任務。第二個下拉菜單有問題。只有第一個下拉菜單功能。我通過循環分隔查詢，但仍然無法正常工作。我能做些什麼來解決它？

$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') { 
        echo '<p><a href="view_sro.php"><i class="fa fa-list" aria-hidden="true"></i> View/Delete SRO</a></p> '; 
       } 

       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> '; 
       } 

       if ($result['url_id'] == '8') { 
        echo '<p><a href="approval_his.php"><i class="fa fa-check-circle" aria-hidden="true"></i> Approval by HIS</a></p> '; 
       } 
      } 
      ?> 
    </ul> 
</li> 
<li> 
    <a href="javascript:;" data-toggle="collapse" data-target="#billing"><i class="fa fa-circle-o-notch"></i> Billing <i class="fa fa-fw fa-caret-down"></i></a> 
    <ul id="billing" class="collapse"> 
     <?php 
     while ($result2 = sqlsrv_fetch_array($query, SQLSRV_FETCH_ASSOC)) { //LOPPING FOR ADMINISTRATION 
      if ($result['url_id'] == '8') { 
       echo '<p><a href="dis_quotation.php"><i class="fa fa-upload" aria-hidden="true"></i> Upload Quotation</a></p>'; 
      } 

      if ($result2['url_id'] == '8') { 
       echo '<p><a href="dis_loa.php"><i class="fa fa-upload" aria-hidden="true"></i> Upload LOA</a></p>'; 
      }  

      if ($result2['url_id']== '13') { 
       echo '<p><a href="dis_atb.php"><i class="fa fa-upload" aria-hidden="true"></i> Upload Advice To Bill</a></p> '; 
      } 

      if ($result2['url_id'] == '19') { 
       echo '<p><a href="dis_invoice.php"><i class="fa fa-upload" aria-hidden="true"></i> Upload Invoice</a></p> '; 
      } 

      if ($result2['url_id'] == '22') { 
       echo '<p><a href="dis_update_payment.php"><i class="fa fa-pencil" aria-hidden="true"></i> Update Payment</a></p> '; 
      } 

      if ($result2['url_id'] == '22') { 
       echo '<p><a href="dis_loa.php"><i class="fa fa-upload" aria-hidden="true"></i> Upload LOA</a></p>'; 
      } 
     } 
     ?> 
    </ul> 
</li> 

Answer 1

您的sqlsrv_fetch_array一旦執行結果就會返回空值。所以第二次你無法從中獲取數據。

如果你想通過第二次環然後你必須重新執行查詢也可以在陣列存儲數據第一，然後通過數組多次迭代。

$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') { 
        echo '<p><a href="view_sro.php"><i class="fa fa-list" aria-hidden="true"></i> View/Delete SRO</a></p> '; 
       } 

       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> '; 
       } 

       if ($result['url_id'] == '8') { 
        echo '<p><a href="approval_his.php"><i class="fa fa-check-circle" aria-hidden="true"></i> Approval by HIS</a></p> ';

      if ($result['url_id'] == '8') {
