Insert products programmatically Prestashop 1.5.6.2 - ERROR link_rewrite is empty

[a2dgroup]

Hi,

 

I'm trying to create a module in prestashop for insert products in my shop by programmatically.

 

Now, I have a button on my module which call the following function:

private function _saveContent()
{
		$message = '';	
		$defaultLanguage = new Language((int)(Configuration::get('PS_LANG_DEFAULT')));  
	$object = new Product();
	$object->price = 22;
	$object->id_tax_rules_group = 0;
	$object->name = 'prova';
        $object->id_manufacturer = 0;
	$object->id_supplier = 0;
	$object->quantity = 1;
	$object->minimal_quantity = 1;
	$object->additional_shipping_cost = 0; 
	$object->wholesale_price = 0;
	$object->ecotax = 0;
	$object->width = 0;
	$object->height = 0;
	$object->depth = 0;
	$object->weight = 0;
	$object->out_of_stock = 0;
	$object->active = 1;
	$object->id_category_default = 22;
	$object->category=array(22);
	$object->available_for_order = 0;
	$object->show_price = 1;			
	$object->on_sale = 0;
	$object->online_only = 1;
	$object->meta_keywords = 'test';			
        $object->description_short = array((int)(Configuration::get('PS_LANG_DEFAULT')) => 'RRR');			
	$object->link_rewrite = array((int)(Configuration::get('PS_LANG_DEFAULT')) => 'RRR');			
	$object->add();
	$message = $this->displayConfirmation($this->l('I prodotti sono stati aggiornati correttamente'));
	return $message;
}

The function insert the product in the database table PREFIX_product; I also see the product in the list on backoffice, but after that the page reply with these errors:

[PrestaShopException]

I think the problems are linked to multilanguage support, but I don't know what to do.

 

Please help me

Hi,

 

I had the same error. I had to follow the code a bit to discover it.

$object							= new Product();
$object->price						= 1;

$object->multilang					= true;

$languages = Language::getLanguages();
foreach ($languages as $language) 
{
	$object->name[ $language['id_lang'] ]			= 'test';
	$object->meta_keywords[ $language['id_lang'] ]		= 'test';
	$object->description[ $language['id_lang'] ]		= 'test';
	$object->description_short[ $language['id_lang'] ]	= 'test';
}

$object->modifierWsLinkRewrite();

if( $object->save() )
	$object->add();

Note modifierWsLinkRewrite() call.

The problem is that you have two languages defined. One language, let's say english with id 1 is deactivated and the other language with id 2 is active and is default language.

The correct assignment for the name property is: $object->name[Configuration::get('PS_LANG_DEFAULT')]
