我想根据顺序选中的复选框存储值。但我有一个错误，如未定义的索引：productadd等等。
设计部分：

当我习惯点击保存按钮后，代码将被执行。但我在开关案例功能中有错误。 Php代码：
if(isset($_POST['Save']))
{
$post['userid'] =($_POST['userid']);
if(!empty($_POST['userid']))
{
// if(is_array($_POST['Products']))
// {
foreach($_POST['screen'] as $post['Pagename'])
{
// myfun($post['Pagename']);
switch($post['Pagename'])
{
case "Products Master":
$post['addition'] =($_POST['Productsadd']);
$post['edit'] =($_POST['Productsedit']);
$post['vieww'] =($_POST['Productsview']);
$post['del'] =($_POST['Productsdelete']);
break;
case "SerialNO":
$post['addition'] =($_POST['SerialNOadd']);
$post['edit'] =($_POST['SerialNOedit']);
$post['vieww'] =($_POST['SerialNOview']);
$post['del'] =($_POST['SerialNOdelete']);
break;
case "Vechile Make":
$post['addition'] =($_POST['Vechileadd']);
$post['edit'] =($_POST['Vechileedit']);
$post['vieww'] =($_POST['Vechileview']);
$post['del'] =($_POST['Vechiledelete']);
break;
case "Retailer":
$post['addition'] =($_POST['RetailerOadd']);
$post['edit'] =($_POST['Retaileredit']);
$post['vieww'] =($_POST['Retailerview']);
$post['del'] =($_POST['Retailerdelete']);
break;
default :
?>
<script type="text/javascript">
alert("Nothing selected.!!");document.location='userrights.php';
</script>
<?
}
//echo $post['Pagename'];
$news->addNews($post);
// }
}
?>
<script type="text/javascript">
alert("Created Sucessfully..!!");document.location='userrights.php';
</script>
<?
}
}

答案 0 :(得分：0)
这将通过在访问之前检查索引是否已设置来修复它。
但是，我建议您考虑使用数组代替复选框将它们分组到集合中以便于解析：
if(isset($_POST['Save']))
{
$post['userid'] = isset($_POST['userid']) ? $_POST['userid'] : null;
if(!empty($_POST['userid']))
{
// if(is_array($_POST['Products']))
// {
foreach($_POST['screen'] as $post['Pagename'])
{
// myfun($post['Pagename']);
switch($post['Pagename'])
{
case "Products Master":
$post['addition'] = isset($_POST['Productsadd']) ? $_POST['Productsadd'] : null;
$post['edit'] = isset($_POST['Productsedit']) ? $_POST['Productsedit'] : null;
$post['vieww'] = isset($_POST['Productsview']) ? $_POST['Productsview'] : null;
$post['del'] = isset($_POST['Productsdelete']) ? $_POST['Productsdelete'] : null;
break;
case "SerialNO":
$post['addition'] = isset($_POST['SerialNOadd']) ? $_POST['SerialNOadd'] : null;
$post['edit'] = isset($_POST['SerialNOedit']) ? $_POST['SerialNOedit'] : null;
$post['vieww'] = isset($_POST['SerialNOview']) ? $_POST['SerialNOview'] : null;
$post['del'] = isset($_POST['SerialNOdelete']) ? $_POST['SerialNOdelete'] : null;
break;
case "Vechile Make":
$post['addition'] = isset($_POST['Vechileadd']) ? $_POST['Vechileadd'] : null;
$post['edit'] = isset($_POST['Vechileedit']) ? $_POST['Vechileedit'] : null;
$post['vieww'] = isset($_POST['Vechileview']) ? $_POST['Vechileview'] : null;
$post['del'] = isset($_POST['Vechiledelete']) ? $_POST['Vechiledelete'] : null;
break;
case "Retailer":
$post['addition'] = isset($_POST['RetailerOadd']) ? $_POST['RetailerOadd'] : null;
$post['edit'] = isset($_POST['Retaileredit']) ? $_POST['Retaileredit'] : null;
$post['vieww'] = isset($_POST['Retailerview']) ? $_POST['Retailerview'] : null;
$post['del'] = isset($_POST['Retailerdelete']) ? $_POST['Retailerdelete'] : null;
break;
default :
?>
<script type="text/javascript">
