如何获取移动上传文件的隐藏错误？ [关闭]

I have this php code:

move_uploaded_file($_POST["filelocation"], "dock/images/".explode("upload/",$_POST["filelocation"])[1]);
putindb();

And the putindb function works fine, I don't get any error, but the file isn't copied. How can i see what error is behind this? Or how can I resolve this?

Use the $_FILES superglobal to get the file paths $_FILES['nameOfFileInputField']['tmp_name'] that will give you the path where the file is.

In your form you should have something like:

<form method="POST" action="whatever.php">
    <input type="file" name="nameOfFileInputField" />
</form>

The type of the input field should be file.
