php mvc update images - php

Question

I have some questions about editing multiple images on my custom PHP MVC code.
Here is controller:
public function izmijeniProizvod() {
$item['item_id'] = $_POST['item_id'];
$item['title'] = $_POST['title'];
$item['description'] = $_POST['description'];
$item['price'] = $_POST['price'];
$item['fk_category_id'] = $_POST['fk_category_id'];
$item['fk_sub_category_id'] = $_POST['fk_sub_category_id'];
$item['active'] = $_POST['active'];
$item['sifra_proizvoda'] = $_POST['sifra_proizvoda'];
$item['image'] = !empty($_FILES['image']['name'][0]) ? $_FILES['image']['name'][0] : '';
$imageFile = $_FILES['image']['name'];
$imageFolder = BASE_PATH.'cdn/proizvodi/' . $item['item_id'] . '/';
$result = $this-> model-> updateItem($item);
for($i = 0; $i < count($imageFile); $i++) :
$item['image'] = !empty($_FILES['image']['name'][$i]) ? $_FILES['image']['name'][$i] : '';
if (!empty($_FILES['image']['tmp_name'][$i]) && $_FILES['image']['error'][$i] == 0 && $_FILES['image']['size'][$i] > 0) :
require_once APP . 'PHPThumb/ThumbLib.inc.php';
if (!is_dir($imageFolder)) :
mkdir($imageFolder);
endif;
if (is_dir($imageFolder)) {
array_map('unlink', glob($imageFolder . '*'));
}
foreach ($this->thumbs as $thumb) :
$newImageFile = $thumb['width'] . 'x' . $thumb['height'] . '_' . $imageFile[$i];
$phpThumb = PhpThumbFactory::create($_FILES['image']['tmp_name'][$i]);
$phpThumb->resize($thumb['width'], $thumb['height'])->save($imageFolder . $newImageFile); //cuva sliku
endforeach;
$this-> model-> updateSlike($item, $imageFile[i]);
endif;
endfor;
And model for this part of code is:
public function updateItem($item) {
$imageSql = !empty($item['image']) ? " , `image` = '{$item['image']}' " : '';
$sql = "UPDATE `items` SET `title` = '{$item['title']}', `active` = '{$item['active']}' , `sifra_proizvoda` = '{$item['sifra_proizvoda']}' , `description` = '{$item['description']}', `price` = '{$item['price']}',
`fk_category_id` = '{$item['fk_category_id']}', `fk_sub_category_id` = '{$item['fk_sub_category_id']}'
$imageSql
WHERE `item_id` = '{$item['item_id']}'";
$result = $this->db->exec($sql);
return $result;
}
public function updateSlike($item){
//$slika = count($item['image']);
$sql = "UPDATE `slike_proizvoda` SET `slika1` = '{$item['image']}' WHERE `item_id` = '{$item['item_id']}'";
$result = $this->db->exec($sql);
return $result;
}
View part of code:
<div class="form-group">
<label class="col-lg-3 control-label">Slika:</label>
<div class="col-lg-8">
<?php if (!empty($this->item['images']['300x300'])) { ?>
<img id="slika" alt="<?php echo $this->item['image']; ?>" src="<?php echo $this->item['images']['300x300'] ?>" />
<?php } ?>
<div class="help-block">
<p>
<label for="image">Izmijeni glavnu sliku:</label>
<input type="file" name="image[]" id="image">
<input type="hidden" name="image[]" />
</p>
<p>
<label for="image2">Ubaci još jednu sliku:</label>
<input type="file" name="image[]" id="image">
<input type="hidden" name="image[]" />
</p>
<p>
<label for="image3">Ubaci još jednu sliku:</label>
<input type="file" name="image[]" id="image">
<input type="hidden" name="image[]" />
</p>
</div>
</div>
Things I get with this parts of code is:
only one imaget get upload, on updateSlike() get only one image name in mysql ...
Thanks.
