问题描述

这是editmaster.php这个错误是什么，我认为一切都很明确。有人帮我。



我尝试过：

<？php session_start（）; 
 include（../ dbConfig.php）;

包括header.php;

 $ description =''; 
 $ item_category =''; 
 $ pic =''; 
 if（isset（$ _ POST ['updateitem']））
 {
 
 if（is_numeric（$ _ POST ['item_id']））
 {
 
 $ item_id = $ _POST ['item_id']; 
 $ item_name = mysql_real_escape_string（htmlspecialchars（$ _ POST ['item_name']））; 
 $ description = mysql_real_escape_string（htmlspecialchars（$ _ POST ['description']））; 
 $ item_category = mysql_real_escape_string（htmlspecialchars（$ _ POST ['item_category']））; 
 $ pic = mysql_real_escape_string（htmlspecialchars（$ _ POST ['pic']））; 
 
 if（$ item_name ==''|| $ description ==''|| $ item_category ==''|| $ pic ==''）
 {
 
 $ error ='错误：请填写所有必填字段！'; 
 
有效（$ item_id，$ item_name，$ description，$ item_category，$ pic，$ error）; 
} 
其他

 mysql_query（UPDATE lost_items_table SET item_name ='$ item_name'，description ='$ description'，item_category ='$ item_category'， pic ='$ pic'WHERE item_id ='$ item_id'）
或die（mysql_error（））; 
 
 header（Location：viewitems.php）; 
} 
} 
其他
 {
 
 echo'错误！'; 
} 
}

} 
	            $item_id = '';
				$item_name = '';
				$description = '';
				$item_category = '';
				$pic = '';
				if (isset($_POST['updateitem']))
				{

				    if (is_numeric($_POST['item_id']))
				{

					$item_id = $_POST['item_id'];
					$item_name = mysql_real_escape_string(htmlspecialchars($_POST['item_name']));
					$description = mysql_real_escape_string(htmlspecialchars($_POST['description']));
					$item_category = mysql_real_escape_string(htmlspecialchars($_POST['item_category']));
					$pic = mysql_real_escape_string(htmlspecialchars($_POST['pic']));

				if ($item_name == '' || $description == '' || $item_category == '' || $pic == '')
				{

				$error = 'ERROR: Please fill in all required fields!';

				valid($item_id, $item_name, $description, $item_category, $pic, $error);
				}
				else
				{

				mysql_query("UPDATE lost_items_table SET item_name = '$item_name', description = '$description', item_category = '$item_category', pic = '$pic' WHERE item_id = '$item_id'")
				or die(mysql_error());

				header("Location: viewitems.php");
				}
				}
				else

				echo 'Error!';
				}
				}
				else

				{

				if (isset($_GET['item_id']) && is_numeric($_GET['item_id']) && $_GET['item_id'] > 0)
				{

				$item_id = $_GET['item_id'];
				$result = mysql_query("SELECT * FROM lost_items_table WHERE item_id=$item_id")
				or die(mysql_error());
				$result1 = mysql_fetch_array($result);

				if($result1)
				{

				$item_name = $result1['item_name'];
				$description = $result1['description'];
				$item_category = $result1['item_category'];
