Yii multiple row insert - php

Question

I have a problem with this code.. When I post 3 images, the script inserts just last one in database.. How can i solve this?
Here's my code:
<?php
function generateRandomString($length = 10) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$randomString = '';
for ($i = 0; $i < $length; $i++) {
$randomString .= $characters[rand(0, strlen($characters) - 1)];
}
return $randomString;
}
$valid_formats = array("jpg", "png", "gif", "bmp");
$max_file_size = 1024*2220; //100 kb
$path = "galerija/"; // Upload directory
$count = 0;
$key = generateRandomString();
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
// Loop $_FILES to execute all files
foreach ($_FILES['files']['name'] as $f => $name) {
if ($_FILES['files']['error'][$f] == 4) {
continue; // Skip file if any error found
}
if ($_FILES['files']['error'][$f] == 0) {
if ($_FILES['files']['size'][$f] > $max_file_size) {
$message[] = "Slika $name je pre velika!.";
continue; // Skip large files
}
elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){
$message[] = "Ekstenzija $name nije valjana!";
continue; // Skip invalid file formats
} else { // No error found! Move uploaded files
if (move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$key.$name)){
$model->naziv = $key.$name;
$model->save();
}
}
}
}
}
?>
I think I should probably put some code after } else { //No error found, but i don't know what :S

You need to create an instance each time like below:
$model=new ModelName();
$model->naziv = $key.$name;
$model->save();
