我在尝试在php中实现编辑页面时遇到问题。
从数据库doesent获取项目会造成任何问题，但尝试更新它会告诉我，我错过了一个字段并试图跳过检查，只留下一张未经编辑的表。
为了解释更多，有一个页面指向这个页面，同时传递一个可验证的id（propertyID），我们用它来获取所需的变量。
任何人都可以查看代码并告诉我我做错了什么，我已经得到了一个类似的页面工作，并且变得非常慌张，试图弄清楚为什么这个。
<?php
// Start sessions
include('includes/security.inc.php');
authorise();
if (!isset($_GET['propertyID']) || !is_numeric($_GET['propertyID']))
{
header('Location:./houselist.php');
}
else
{
// Include connection file
include('includes/connection.inc.php');
// Get details
connect();
$propertyID = $_GET['propertyID'];
$sql = "SELECT * FROM Properties WHERE propertyID='$propertyID' LIMIT 1";
$result = @mysql_query($sql) or die('Unable to run query');
$record = mysql_fetch_object($result);
mysql_close();
// Check to see if the form has been submitted
if (isset($_POST['submit']))
{
// Check to see all fields have been completed
$address = $_POST['address'];
$categoryID = $_POST['categoryID'];
$price = $_POST['price'];
$landlordName = $_POST['landlordName'];
$img = $_POST['img'];
$description= $_POST['description'];
if (!empty($address) && !empty($categoryID) && !empty($price) && !empty($landlordName) && !empty($img) && !empty($description))
{
// Create an SQL query to add the comment
$sql = "UPDATE property SET propertyID = '$propertyID', img = '$img', address = '$address', price = '$price', landlordName = '$landlordName', description = '$description' WHERE propertyID = $propertyID";
// Connect to the database
connect();
// Run the query and store the result in a variable
$result = mysql_query($sql) or die("Could not run query1");
// Close connection to the database
mysql_close();
// Check if query was successful
if ($result)
{
$message = '<div class="success"><p>You have successfully edited Article details.</p><p>Please <a href="Animal_Manage.php">Click Here</a> to view the Animal list.</p></div>';
}

我对问题的最佳猜测将围绕
// Check to see if the form has been submitted
if (isset($_POST['submit']))
{
// Check to see all fields have been completed
$address = $_POST['address'];
$categoryID = $_POST['categoryID'];
$price = $_POST['price'];
$landlordName = $_POST['landlordName'];
$img = $_POST['img'];
$description= $_POST['description'];
if (!empty($address) && !empty($categoryID) && !empty($price) && !empty($landlordName) && !empty($img) && !empty($description))
{
// Create an SQL query to add the comment
$sql = "UPDATE property SET propertyID = '$propertyID', img = '$img', address = '$address', price = '$price', landlordName = '$landlordName', description = '$description' WHERE propertyID = $propertyID";
// Connect to the database
connect();
// Run the query and store the result in a variable
$result = mysql_query($sql) or die("Could not run query1");
// Close connection to the database
mysql_close();
// Check if query was successful
if ($result)
{
$message = '<div class="success"><p>You have successfully edited Article details.</p><p>Please <a href="Animal_Manage.php">Click Here</a> to view the Animal list.</p></div>';
}
else

$message = '<div class="error"><p>There was an error editing details, please try again</p></div>';
}
}

$message = '<div class="error"><p>Please make sure you fill all fields in before submitting the form.</p></div>';
}
}
