Hi, I have this script:

<?php

$time_start = microtime(true);
$import = 'eshop.csv';
require(dirname(__FILE__) . '/../config/config.inc.php');
$connect = mysql_connect(_DB_SERVER_, _DB_USER_, _DB_PASSWD_) or die('nelze se pripojit');
mysql_select_db(_DB_NAME_, $connect);
mysql_query("Set names 'utf8'");
if (file_exists($import)) {

    $ids = array();
    $query = mysql_query('SELECT ean13,id_product FROM ' . _DB_PREFIX_ . 'product');
    while ($row = mysql_fetch_array($query)) {
        $ids[(string) $row['ean13']] = $row['id_product'];
    }

    $file = file_get_contents($import);
    $lines = explode(PHP_EOL, $file);
    foreach ($lines as $line) {
        $data = explode(';', $line);
        $ean = (string) $data[0];
        $price = (float) $data[1];
        $quantity = (int) $data[2];
        if (array_key_exists($ean, $ids)) {
            $id = (int) $ids[$ean];
            $product = new Product($id);
            $product->price = $price
            $product->update();
            $sql = 'UPDATE `' . _DB_PREFIX_ . 'stock_available` SET quantity = "' . $quantity . '" WHERE id_product="' . $id . '"';
            mysql_query($sql);
        }
    }
    unlink($import);
}
?>

Script loading lines with these data:

EAN;price with tax;quantity

Is there any way to update quantity in $product->update() and price update with tax like this:

<?php
$product = new Product($id);
$product->price_tax_include = $new_price;
$product->quantity = $new_quantity;
$product->update();
?> 

I tried:

<?php
$product = new Product($id, true);
?>

and:

<?php
$product = new Product($id, true, $context->language->id);
?> 

to load full product info, but get "Fatal error"

 

Thak you
