一旦满足if条件，我想在变量中插入日期时间戳。但我得到以下错误：
注意：未定义的索引：第55行C:\wamp\www\business\edit_log_widget.php中的状态
以下是php代码：
<?php

include 'html/header.php';
$page = 'servers';
$id =$_SESSION['logid'];
$query = "SELECT *FROM log WHERE logid = $id";
$query_submit = mysql_query($query) or die(mysql_error);
$row = mysql_fetch_assoc($query_submit);
?>

}
else

您尚未为选项指定任何值；）
<option value="Resolved">Resolved</option>
PHP代码在表单提交之前执行，因此尚未定义$_POST[‘status’]。
$_POST['status']
阵列$_POST的进入状态未定义
您正在尝试访问尚未设置的变量。
为了避免这种情况，你可以先检查一下，如果表格是在之前提交的
<?php
if(!empty($_POST['Submit'])){
if($_POST['status']== 'Resolved')
{
$today = DateTime::createFromFormat('!Y-m-d',date('Y-m-d')); // This is Line 55
}
if(isset($_GET['success']) && empty($_GET['sucess']))
{
echo 'the log has been captured';
}
else
{
if(empty($_POST) === false && empty($errors)=== true)
{
//Update Log details
$update_log = array(
'task_name'=>$_POST['task_name'],
'description' => $_POST['description'],
'solution' =>$_POST['solution'],
'status'=>$_POST['status'],
'closed_date'=>$today,
'userid' =>$_SESSION['userid']);
update_log($update_log);
//redirect
header('Location: edit_log_widget.php?success');
exit();
}
else if(empty($errors) === false)
{
//output errors if the errors array is not empty
echo output($errors);
}
}
}
?>
您缺少一些html道具，您的<option>必须有一个value道具，如下所示：
<td>
<select id="Select2" name="status">
<option value="0">-Select-</option>
<option value="1">Resolved</option>
<option value="2">Un-resolved</option>
<option value="3">In-Progress</option>
</select>
</td>
你得到这个错误是因为你在第一个html片段中遗漏了它，而在第二个html片段中有它，所以PHP没有任何东西可以得到
我将所有php移到了html表单的顶部，现在它工作得很好。感谢大家帮助我完成
