Hello there!
I need some help on a script. I have a form with that edits a row in the database, a form that have a browse button for images. What i need is to run a code if the field LajmeImg is not blank and anothe code if is blank.

I have used this 2 ways:

1.

if(empty($_FILES['LajmeImg']) && ($error == '')) {

            $sql = "UPDATE lajme SET KatLajmeID = '$KatLajmeID', LajmeEmri = '$LajmeEmri', LajmeLink = '$LajmeLink', LajmeIntro = '$LajmeIntro', LajmeTxt = '$LajmeTxt', LajmeVideo = '$LajmeVideo', LajmeTag = '$LajmeTag', LajmeAktiv = '$LajmeAktiv' WHERE LajmeID = '$LajmeID'";

            $query = mysql_query($sql) or die("Fatal error: ".mysql_error());

            }

            else if (!empty($_FILES['LajmeImg']) && ($error == '')) {

            $sql = "UPDATE lajme SET KatLajmeID = '$KatLajmeID', LajmeEmri = '$LajmeEmri', LajmeLink = '$LajmeLink', LajmeIntro = '$LajmeIntro', LajmeTxt = '$LajmeTxt', LajmeVideo = '$LajmeVideo', LajmeTag = '$LajmeTag', LajmeImg = '$LajmeImg', LajmeAktiv = '$LajmeAktiv' WHERE LajmeID = '$LajmeID'";

            $query = mysql_query($sql) or die("Fatal error: ".mysql_error());

2.

if(($LajmeImg == '') && ($error == '')) {

        

            $sql = "UPDATE lajme SET KatLajmeID = '$KatLajmeID', LajmeEmri = '$LajmeEmri', LajmeLink = '$LajmeLink', LajmeIntro = '$LajmeIntro', LajmeTxt = '$LajmeTxt', LajmeVideo = '$LajmeVideo', LajmeTag = '$LajmeTag', LajmeAktiv = '$LajmeAktiv' WHERE LajmeID = '$LajmeID'";

            $query = mysql_query($sql) or die("Fatal error: ".mysql_error());

            }

            else if (($LajmeImg !== '') && ($error == '')) {

            $sql = "UPDATE lajme SET KatLajmeID = '$KatLajmeID', LajmeEmri = '$LajmeEmri', LajmeLink = '$LajmeLink', LajmeIntro = '$LajmeIntro', LajmeTxt = '$LajmeTxt', LajmeVideo = '$LajmeVideo', LajmeTag = '$LajmeTag', LajmeImg = '$LajmeImg', LajmeAktiv = '$LajmeAktiv' WHERE LajmeID = '$LajmeID'";

            $query = mysql_query($sql) or die("Fatal error: ".mysql_error());

but, in both of them, when the field is empty didn't let the "LajmeImg" DB field out of the query but updates the database with a value that i don;t know where it gets that and have only the name of the image existent on the DB without extension (ex: if the existent image name is [B]imagename.jpg[/B] now it looks like [B]imagename.[/B]). I supose that this mean that "if" statement didn;t worked correctly. This is the hole code of the edit page:

<?php
include('header.php');
include ('includes/uploader.class.php');
      
    // Uploader strings starts
   
    $uploader = new uploader();
    // Setting properties then Uploading the image
    $uploader->destDir = "D:/Program Files/VertrigoServ/www/oldi/imazhet/artikuj/";
    $uploader->upload($_FILES['LajmeImg']);
   
    // Uploader strings end
   
include('lart.php');
if(!$_GET['lajmeid'] && !isset($_POST['do_edit']) && !isset($_POST['edit_lajme'])) {

echo $error;

// Shfaq listen e lajmeve
lajmet_lista();

}



// Has the edit form been submitted?

if(isset($_POST['do_edit'])) {
   
    $LajmeID = $_POST['LajmeID'];
    $LajmeEmri = $_POST['LajmeEmri'];
    $KatLajmeID = $_POST['KatLajmeID']; // Kategoria Lajmeve
    $LajmeIntro = $_POST['LajmeIntro'];
    $LajmeTxt = $_POST['LajmeTxt'];
    $LajmeAktiv = $_POST['LajmeAktiv'];
    $LajmeTag = $_POST['LajmeTag'];
    $LajmeVideo = $_POST['LajmeVideo'];
    $LajmeLink = $_POST['LajmeLink'];
    //$LajmeImg = $_FILES['LajmeImg']['name']; // Me autoName = False; regjistron ne db emrin real te fotografise
    $LajmeImg = $uploader->source['name']; // Me autoName = true; regjistron ne db emrin random te fotografise i gjeneruar ne base64

   
    $fshij = $_POST['fshij'];

   
    // Ticked the 'delete category' box? If so, delete and echo message.   
    if($fshij == 'fshij_LajmeID' && $error == '') {
       
    $sql =  "DELETE FROM lajme WHERE  LajmeID=$LajmeID LIMIT 1";
    $query = mysql_query($sql) or die("Fatal error: ".mysql_error());
