multiples upload rename (while function) - php

Question

Okay so, the below php upload script already WORK, the part didn't work is only of renaming file if exist.
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
foreach ($_FILES['files']['name'] as $f => $img_name) {
if ($_FILES['files']['error'][$f] == 4) {
continue;
}
if ($_FILES['files']['error'][$f] == 0) {
if ($_FILES['files']['size'][$f] > $max_file_size) {
$message[] = "$img_name est trop lourde !";
continue;
}
elseif( ! in_array(pathinfo($img_name, PATHINFO_EXTENSION), $valid_formats) ){
$message[] = "$img_name est pas valide !";
continue;
}
else{
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$img_name)) {
while(file_exists($path . $img_name)){
$increment++;
$img_name = $name.$increment.'.'.$extension;
$count++;
}
}
}
}
}
}
I have search a lot on php doc, try fews fews way to go but .. when i'm trying a file with a name already uploaded before, it's not changing the actual upload file.

You are determining the filename after you upload the file. determine it before.
Change like:
while(file_exists($path . $img_name)){
$increment++;
$img_name = $name.$increment.'.'.$extension;
$count++;
}
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$img_name)) {
// File Uploaded !!!
}
Edit:
I have changed your code. Comments in code.
$valid_formats = array("jpg", "JPG", "png", "PNG" , "bmp", "BMP");
$max_file_size = 1024*6000; //60 000 kb - 6 mb
$path = "../../../img/final/img_recipes/"; //directory
$count = 0;
$uploaded_image_names = array(); //create a new array
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
foreach ($_FILES['files']['name'] as $f => $img_name) {
if ($_FILES['files']['error'][$f] == 4) {
continue;
}
if ($_FILES['files']['error'][$f] == 0) {
if ($_FILES['files']['size'][$f] > $max_file_size) {
$message[] = "$img_name est trop lourde !";
continue;
}
elseif( ! in_array(pathinfo($img_name, PATHINFO_EXTENSION), $valid_formats) ){
$message[] = "$img_name est pas valide !";
continue;
}
else{
// Moved name and extension initialization to here.
// Here is where you want to determine the actual filename
$name = pathinfo($img_name, PATHINFO_FILENAME);
$extension = pathinfo($img_name, PATHINFO_EXTENSION);
$increment = 0;
while(file_exists($path . $img_name)){
$img_name = $name.$increment.'.'.$extension;
$increment++;
}
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$img_name)) {
$count++;
//Store the uploaded filenames to array here
$uploaded_image_names[] = $path.$img_name;
}
}
}
}
}
foreach ($uploaded_image_names as $uploaded_image_name){
//store the $uploaded_image_name to db
}
Note: I have not tested this, as I don't have PHP available with me now.
