If-Else语句错误

Question

The program should be like this : 该程序应如下所示：

The code will check if there's any file available for uploading. 该代码将检查是否有任何文件可上传。
If there's any file found. 是否找到任何文件。 It will upload and the texts will save in the database. 它将上传并且文本将保存在数据库中。
But if there's no file found, it will not upload and the path will not also save but the texts will still save in the database. 但是，如果找不到文件，则不会上传文件，路径也不会保存，但文本仍会保存在数据库中。

What really happens: 实际发生的情况：

The texts are saving 文本正在保存
The image path is still saving! 图像路径仍在保存！ So it'll be a problem for retrieving the image on the later part. 因此，在后面的部分中检索图像将是一个问题。

As you noticed: 如您所见：

I removed the avatar_image_path on if that's how I thought for the image path not to be saved but it is still saving. 我删除了avatar_image_path ， if那是我认为不保存图像路径但仍在保存的方式。

Code: 码：

 if ($_FILES["file"]["name"] == 0)
    {

    $updateQuery = "UPDATE  `users`.`info` SET  `password` =  '$newPass',`contact_number` =  '$newConNum',`user_address` =  '$newAdd',`email_address` = '$newEmail', WHERE  `info`.`username` =  '$username' AND  `info`.`password` =  '$userpass' AND `info`.`firstname` =  '$firstName' AND  `info`.`lastname` =  '$lastName' AND  `info`.`admin_level` =$adminLvl AND  `info`.`contact_number` =  '$ConNum' AND  `info`.`user_address` =  '$usrAdd' AND `info`.`avatar_image_path` =  '$avaImgPth' ";
    $executeQuery=$con->query($updateQuery);
    echo "Profile successfully UPDATED!";

      }

 else
    {
    move_uploaded_file($_FILES["file"]["tmp_name"], "avatar/owner-".$_SESSION['username']."-fname-".$_SESSION['fname']."-l_name-".$_SESSION['lname']."-filename-".$_FILES["file"]["name"]);
    $updateQuery1 = "UPDATE  `users`.`info` SET  `password` =  '$newPass',`contact_number` =  '$newConNum',`user_address` =  '$newAdd',`email_address` = '$newEmail',`avatar_image_path` =  '$filepath' WHERE  `info`.`username` =  '$username' AND  `info`.`password` =  '$userpass' AND `info`.`firstname` =  '$firstName' AND  `info`.`lastname` =  '$lastName' AND  `info`.`admin_level` =$adminLvl AND  `info`.`contact_number` =  '$ConNum' AND  `info`.`user_address` =  '$usrAdd' AND `info`.`avatar_image_path` =  '$avaImgPth' ";
    $executeQuery1=$con->query($updateQuery1);

    echo "Profile successfully UPDATED!";
    }

Answer 1

first of all you have to save old profile image in hidden field. 首先，您必须将旧的个人资料图片保存在隐藏字段中。

<html>
<input type="hidden" name="old_image" value=<?php echo $row['image'];?>/>
<input type="file" name="new_image"/>
</html>

now when you submit a form then check 现在，当您提交表格时，然后检查

<?php
if($_FILES['new_image']['name']!="" && $_POST['old_image']=="")
{
echo "upload process...";
}
else
{
echo "save old image in database.";
}
?>
