我有一个表单，可以将图像上传到我的服务器并将图像的路径存储在 MySQL 中，并且该表单可以完美运行。我现在想要做的是能够更新存储在 MySQL 中的存储图像和路径，但我不知道如何将 $target 变量添加到我的代码中，以便它更新 MySQL 中的路径和文件名。我现在拥有代码的方式将上传新图像，但不会更新 MySQL 中的路径和名称，我知道它与 $target 有关，我只是不知道把它放在哪里。是的，我很清楚 sql 注入，所以请不要评论它，因为我不关心这种情况。
<?php
//This is the directory where images will be uploaded and saved
$target = "uploads/cheer/";
$target = $target . basename($_FILES['member_photo']['name']);
//This gets all the form data//
//----------MEMBER INFO----------//
$team_name=$_POST['team_name'];
$first_name=$_POST['first_name'];
$last_name=$_POST['last_name'];
$registration=$_POST['registration'];
$pay_status=$_POST['pay_status'];
$physical=$_POST['physical'];
$photo=$_POST['photo'];
$logo_src=$_POST['logo_src'];
//----------NOTES----------//
$notes=$_POST['notes'];
//----------IMAGES----------//
$pic=($_FILES['member_photo']['name']);
//----------CONNECT TO DATABASE----------//
include 'elite_connect.php';
//----------WRITES DATA TO DATABASE----------//
mysql_query("UPDATE cheer SET team_name='$team_name', first_name='$first_name', last_name='$last_name', registration='$registration', pay_status='$pay_status', physical='$physical', photo='$photo', logo_src='$logo_src', notes='$notes', member_photo='$member_photo',
WHERE `id` = '$id'");
//----------DISPLAYS MYSQL ERRORS----------//
print_r($_POST);
echo mysql_error();
//----------WRITES PHOTO TO SERVER----------//
if(move_uploaded_file($_FILES['member_photo']['tmp_name'], $target))
{
//----------TELLS IF ALL IS OK----------//
echo "The file ". basename($_FILES['member_photo']['name']). "has been uploaded!";
}
else {
//----------GIVES AN ERROR IF IT'S NOT----------//
?><br/><?php
echo "Sorry, there was a problem uploading your image.";
}
?>
将 $target 添加到 SET 会从 process_edit.php 文件中产生以下错误
数组（[id] => 18 [first_name] => 你的 [last_name] => 爸爸 [team_name] => [registration] => YES [pay_status] => PENDING [physical] => NO [photo] => [notes ] => 我是你爸爸 [logo_src] => logos/cougars2013.jpg [submit] => 更新会员）你的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 1 行的 ''uploads/cheer/helmet1.jpg' WHERE
id= ''' 附近使用正确的语法文件helmet1.jpg 已上传！
如您所见，更新正在写入 MySQL，并且图像已上传到服务器，但图像的路径未更新。
所以回显整个查询几乎给出了与上面完全相同的东西，
数组（[id] => 20 [first_name] => Fat [last_name] => Amy [team_name] => [registration] => YES [pay_status] => 已全额支付 [physical] => YES [photo] => YES [notes] => Large and in Charge! [logo_src] => logos/gvklogo2013.png [submit] => Update Member ) 你的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 12 行的 'uploads/images/fatamy.png='uploads/images/fatamy.png' WHERE
id= '20'' 附近使用正确的语法文件 fatamy.png 有已上传！
如果这有帮助，这里是处理输入表单以上传文件和存储路径的代码。
