End code php:
<form action="upload_file.php" method="post" enctype="multipart/form-data" name="upload_file"><br>
<label for="UploadFileField"></label><br>
<input type="file" name="UploadFileField"/>
<input type="submit" name="UploadButton" value="Upload" /><br>

$UploadType = $_FILES['UploadFileField'] ['type'];
$FileSize = $_FILES['UploadFileField'] ['size'];
$UploadName = preg_replace("#[^a-z0-9.]#i", "", $UploadName);
if(($FileSize > 1250000)){
die ("Error - File to big");
}
if(!$UploadTmp) {

}
else {
if (move_uploaded_file($UploadTmp, "Upload/$UploadName")) {
$UPLOAD_COD = $_POST['UPLOAD_COD'];
$sql = "INSERT INTO download (ID_PRODUCT,LINK_DOWNLOAD) VALUES ('$UPLOAD_COD','Upload/$UploadName')";

2015.03.12.pdf file is today updating and becomes 2016.09.25.pdf . When i enter in the input "UPLOAD_COD" the number 2369, I want to delete the file 2015.03.12.pdf from server and be replaced with 2016.09.25.pdf, and in the LINK_DOWNLOAD column to be updated to the new link (folder/2015.03.12.pdf). Thank you!
