update or delete product images, categories and attributes programmatically

[cronempower]

Hello,

 

I'm new in prestashop and i'm trying to create, update and delete product with custom code.

 

I create a product with 

 

$product = new Product();

$product->name;

.....

$product->addToCategories(array($cat));

 

upload images

and attributes with 

 

$countsize = count($get_size);

for ($y=0; $y < $countsize; $y++)

{

$combinationAttributes = array();

$combinationAttributes[] = $get_size[$y];

$combinationAttributes[] = $get_color[$y];

/*echo '<pre>';

print_r($combinationAttributes);

echo '</pre>';*/

if(!$product->productAttributeExists($combinationAttributes))

{

$quantity = $get_qty[$y];

$reference = $get_all_sku[$y];

 

if ($y==0) $default = true; else $default = false;

 

$idProductAttribute = $product->addProductAttribute((float)$price, (float)$weight, $unit_price_impact, (float)$ecotax, (int)$quantity, "", strval($reference), strval($supplier_reference), strval($ean13), $default, NULL, NULL);

$product->addAttributeCombinaison($idProductAttribute, $combinationAttributes);

}

 

}

 

and it works.

 

I delete a product with 

$product = new Product($id_product, null, $id_lang, $id_shop, Context::getContext()->shop->setContext(Shop::CONTEXT_SHOP, $id_shop));

 

if ($product->delete()) echo 'Deleted'; else echo 'NOT deleted';

 

and i update a product

$product = new Product($product_id);

$product->setFieldsToUpdate(array('price','name','weight','id_manufacturer','reference','description','id_category_default','wholesale_price','link_rewrite'));

$product->name = "test";

$product->save();

 

but i cannot update images or attributes

 

I think is better to delete first images and attributes and create them again.

 

So how can i update or delete images and attributes in single product?

 

Sorry for my english
