试图用PHP更新我的MySQL数据库中的记录。我是一个PHP noob，所以我假设我失去了一些明显的东西。简单SQL更新语句语法
我的新代码（update-task.php） - 它提交并重定向，但记录没有更新。
<?php
$data = array(
'id' => $_POST['id'],
'TaskName' => $_POST['TaskName'],
'ClientName' => $_POST['ClientName'],
'AssignedTo' => $_POST['AssignedTo'],
'DueDate' => $_POST['DueDate'],
'TimeLogged' => $_POST['TimeLogged'],
'Notes' => $_POST['Notes'],
'Urgent' => $_POST['Urgent']
);
require('mysql.php');
$db = new mysql;
$db->connect('localhost', 'my_user', 'my_pass;', 'my_db');
$db->query("UPDATE `my_table` SET TaskName='" . mysql_real_escape_string($data['TaskName']) . "',
ClientName='" . mysql_real_escape_string($data['ClientName']) . "',
AssignedTo='" . mysql_real_escape_string($data['AssignedTo']) . "',
DueDate='" . mysql_real_escape_string($data['DueDate']) . "',
TimeLogged='" . mysql_real_escape_string($data['TimeLogged']) . "',
Notes='" . mysql_real_escape_string($data['Notes']) . "',
Urgent='" . mysql_real_escape_string($data['Urgent']) . "' WHERE id='" . mysql_real_escape_string($data['id']) . "'
");
header('Location:saved.htm');
我的形式看起来像这样（视图task.php）
<?php
$id = $_GET['id'];
require('mysql2.php');
$db = new mysql;
$db->connect('localhost', 'my_user', 'my_pass;', 'my_db');
$query = $db->query("SELECT * FROM `table_name` WHERE id = '" . $id ."'");
while($result = $db->fetch_array($query)) {
$data = $result;
}
?>
<form action="update-task.php" method="post" id="form1" name="form1">
<label>Task Name:</label>
<input name="TaskName" type="text" id="TaskName" size="30" value="<?php echo $data['TaskName']?>"/>

<input type="button" value="Clear Timer" onClick="clearTimer()">
<label>Notes</label>
<input name="Notes" type="textarea" id="Notes" size="30" value="<?php echo $data['Notes']?>"/>
<label>Urgent</label>
<input name="Urgent" type="text" id="Urgent" size="30" value="<?php echo $data['Urgent']?>"/>
<input type="submit" value="Update" class="AddButton">
</form>

Call类为'$ DB =新的MySQL（）;'< - – Saty
@Saty我试过，但仍然得到错误“您在你的SQL语法中有一个错误;查看与你的MySQL服务器版本相对应的手册，在'VALUES（0，'任务2'，'客户端测试'，'人'，'04/14/2017' '，'0'，'第一行'在第一行“ – josefresco
