我有兩個php頁面，admin_bkp.php和db_submit.php。Comboboxes沒有更新
的admin_bkp.php給用戶，它可以讓用戶設置權限爲員工和權限保存到一個MySQL表的表稱爲權利。員工信息從hs_hr_employee收集並保存到權限以及附加'權限'列。
剛開始工作時，您可以保存數據，當您刷新頁面時，admin_bkp.php將顯示組合框中的默認值，就像您先前選擇的那樣。
不過，現在它是作爲這是我不希望「所有」返回默認值。我希望它顯示之前選擇的值。
的admin_php.bkp在點擊'保存' 按鈕
這是代碼保存值： admin_bkp.php
<?php
$connection = mysql_connect('localhost','admin','root');
if(isset($_POST['submit']))
{
if(isset($_POST['cb_change']) && is_array($_POST['cb_change']))
{
foreach($_POST['cb_change'] as $emp_number => $permission)
{
echo "$permission";
$sql = "UPDATE `rights` SET Permission='".mysql_real_escape_string($permission)."' WHERE emp_number='".mysql_real_escape_string($emp_number)."'";
echo __LINE__.": sql: {$sql}\n";
mysql_query($sql);
}
}
}
?>

能不能請點我在正確的方向？
所以我基本上替換代碼片段與所述一個你給了我？ – Brian
我試過的是這個，但它顯示了多個組合框，我不想要的東西。我想要的是一個組合框，默認情況下顯示以前選擇的選項。我更新了主要問題中的代碼，以便了解我所做的工作。 – Brian
我給你的代碼循環訪問每個權限（存儲在數組中），併爲每個權限輸出一個
