Importação de produtos CSV de fundo / cron PRESTASHOP

Aqui está um código útil que uso em um de meus projetos com uma configuração de várias lojas PRESTASHOP (v1.5.6) para importar produtos automaticamente para cada loja. Primeiro, eu gerei o arquivo CSV com os dados do produto que desejo inserir ou atualizar, em seguida, o script faz login como você faria na área de administração prestashop e POST os dados no controlador AdminImport.

Aqui está o script de background / cron e abaixo da classe curl wrapper (você pode substituir o curl wrapper php, é claro)

require_once ('class.PSRequest.php'); //see class source code below

$shopID = "myfirstshop"; // ID or unqiue name of the target shop
$products = ...; // your set of product object or array

// CSV first line for products
$csv = "id;Active (0/1);Name*;Categories (x,y,z,...);Price tax excluded;Tax rules id;Wholesale price;On sale (0/1);Discount amount;Discount percent;Discount from (yyy-mm-dd);Discount to (yyy-mm-dd);Reference #;Supplier reference #;Supplier;Manufacturer;EAN13;UPC;Ecotax;Weight;Quantity;Short description;Description;Tags (x,y,z,...);Meta-title;Meta-keywords;Meta-description;URL rewritten;Text when in-stock;Text if back-order allowed;Available for order (0 = No, 1 = Yes);Product creation date;Show price (0 = No, 1 = Yes);Image URLs (x,y,z,...);Delete existing images (0 = No, 1 = Yes);Feature (Name:Value:Position);Available online only (0 = No, 1 = Yes);Condition (new,used,refurbished);ID / Name of shop".PHP_EOL;

foreach ($products as $prod) {
        // fill in the csv string with your datas
       $csv .= $prod->id.";1;".html_entity_decode($prod->name)......$shopID.PHP_EOL;
}

$now=time();
$csvname = $now."-PRODUCTS-".$shopID.".csv";
$file = YOUR_PATH.$csvname;
file_put_contents($file, $csv);

echo "Write file : ".$file.PHP_EOL;

echo "Login on Prestashop Admin area...".PHP_EOL;   
$adminUrl = "http://YOUR_PS_ADMIN/adminXXXX/"; // change that with your admin url of course
$request = new PSRequest();
$request->setCookiFileLocation(__DIR__.'/PScookie.txt');

$request->setPost(array("email" => "YOUR_ADMIN_EMAIL","passwd" => "YOUR_ADMIN_PASS", "submitLogin" => "Connexion")); // you must be a super admin
$request->call($adminUrl."index.php?controller=AdminLogin");

echo "Get token...".PHP_EOL;

$request->call($adminUrl."index.php?controller=AdminImport");
list(,$response) = explode("rnrn", $request->_webpage, 2);
preg_match("/token=([a-z0-9]+)/", $response, $matches);
$token = $matches[1];

echo "Token : ".$token.PHP_EOL;

// Send POST datas just like the admin form would do it, those datas depends on what you want to do : check the import admin page.
$request->setPost(array(
    "controller"               => "AdminImport",
    "token"                    => $token,

Aqui está a classe curl do wrapper

        else {

    }

    public function __tostring(){
        return $this->_webpage;
    }

}

e é isso. Basta configurar seu cron como este, por exemplo:

@daily /usr/bin/php /path/to/my_script.php > /dev/null 2>&1

Você pode adicionar um log para a lógica do arquivo ao script para verificar se tudo correu bem!
