edit uploaded image with using class.upload.php - php

Question

I made simple upload system with using class.upload.php and it works great while adding new into database. But i have problem when i need to edit my entry. While editing entry i don't want to edit image but it sent it blank, also if i select image again it sent it blank too. Here is my code.
Can explain my problem.
<?php require_once("conn.php");
require_once ("class.upload.php");
$catid = $_POST['catid'];
$title = $_POST['title'];
$descc = $_POST['descc'];
$keyw = $_POST['keyw'];
$message = $_POST['message'];
$Image = $_FILES['Image'];
$randnum = rand();
$foo = new upload($Image);
$filee = './Image';
if ($foo->uploaded) {
$foo->image_resize = true;
$foo->file_new_name_body = $randnum;
$foo->image_x = 550;
$foo->image_y = 440;
$foo->process($filee);
if ($foo->processed) {
echo 'Image uploaded.';
echo $foo->file_dst_name;
$foo->clean();
} else {
echo 'Error. : ' . $foo->error;
}
}
$Image7 = $foo->file_dst_name;
if($_GET[pass] == 1)
{
if(!isset($_POST[catid]) || empty($_POST[catid])){
$hata = "Required area.";
}
if(!isset($_POST[title]) || empty($_POST[title])){
$hata = "Required area.";
}
if(!isset($_POST[descc]) || empty($_POST[descc])){
$hata = "Required area.";
}
if(!isset($_POST[keyw]) || empty($_POST[keyw])){
$hata = "Required area.";
}
if(!isset($_POST[message]) || empty($_POST[message])){
$hata = "Required area.";
}
if(!$hata){
mysql_query("UPDATE product SET
catid='$_POST[catid]',
title='$_POST[title]',
descc='$_POST[descc]',
keyw='$_POST[keyw]',
message='$_POST[message]',
Image='$_POST[Image]'
WHERE id='$_POST[id]'
");
$mesaj = "OK!";
}
}
$sonuc = mysql_query("select * from product WHERE id='$_GET[product]'");
$edit = mysql_fetch_array($sonuc);
$sonuc1 = mysql_query("select * from category");
$edit1 = mysql_fetch_array($sonuc1);
?>

Answer 1

try to change the update query
at Image='$_POST[Image]'
with Image='$Image7'

Answer 2

Fatih you can use a variable (i.e. $saved_image_name) instead of $POST[Image] at sql query. Set this variable to new name if uploaded else old value of db field.
...
...
$foo = new upload($Image);
$filee = './Image';
$saved_image_name = " Image "; // name of db field.
if ($foo->uploaded) {
$foo->image_resize = true;
$foo->file_new_name_body = $randnum;
$foo->image_x = 550;
$foo->image_y = 440;
$foo->process($filee);
if ($foo->processed) {
echo 'Image uploaded.';
echo $foo->file_dst_name;
// Note the quotes
$saved_image_name = " '$foo->file_dst_name' ";
$foo->clean();
} else {
echo 'Error. : ' . $foo->error;
}
}
// no use anymore $Image7 = $foo->file_dst_name;
...
...
if(!$hata){
mysql_query("UPDATE product SET
catid='$_POST[catid]',
title='$_POST[title]',
descc='$_POST[descc]',
keyw='$_POST[keyw]',
message='$_POST[message]',
Image= $saved_image_name // note the quotes
WHERE id='$_POST[id]'
");
...
