CSV stock import for Prestashop 1.6 - php

Question

I would like to create a simple php script that I can run a stock overwrite to my products in Prestashop 1.6. It will need to reference the "product reference" which in my file is "SKU" and then update the "quantity" in Prestashop which is "Available Stock" in my spreadsheet.
At present I am updating this manually every day as I am given a csv file with live stock updates from my supplier. I have seen modules but none of them seem to work for us so hoping theres a simple maybe php script someone has created that would just overwrite the data in the db.
Thanks in advance

Answer 1

Here is an script i use on PS 1.6 for update stock for "product" or "product_attribute" by UPC.
the CSV file in stock/ folder look like :
product ref;stock move;id shop
4443601522;0;1
you can change this scrit to use SKU instead of UPC
<?php
include(dirname(__FILE__) . '/config/config.inc.php');
include(dirname(__FILE__) . '/init.php');
$id_shop = 1;
$id_lang = 1;
$ligne = 0;
$dossier_csv = "/home/mywebsite/public_html/stock/";
echo '<H1>MAJ PS STOCK PAR UPC</h1>';
if (($fic = fopen($dossier_csv . "stock.csv", "a+")) == FALSE) {
echo '<br>Erreur ouverture fichier stock !<br>';
} else {
echo '<h2><u>Traitement des stocks :</u></h2>';
}
while ($tab = fgetcsv($fic, 1024, ';')) {
$champs = count($tab);
$ligne++;
for ($i = 0; $i < $champs; $i++) {
if ($i == 0)
$reference = $tab[$i];
if ($i == 1 && $reference != '' && $ligne != 1) {
$quantity = $tab[$i];
$productId = getIdProductByUPC($reference);
if ($productId != false) {
$idProductAttribute = getIdByUPC($productId, $reference);
$newStock = $quantity;
StockAvailable::setQuantity($productId, $idProductAttribute, $newStock, $id_shop);
echo '<br>(' . $reference . ') : OK qte : <b>' . $quantity . '</b><br>';
} else {
$productId = Product::getIdByUPC($reference);
$product = new Product($productId);
$combination = $product->getAttributeCombinations($id_lang);
if ($productId != false && count($combination) == 0) {
$newStock = $quantity;
StockAvailable::setQuantity($productId, 0, $newStock, $id_shop);
echo '<br>(' . $reference . ') : OK qte : <b>' . $quantity . '</b><br>';
} else {
echo '<br>(' . $reference . '-' . $productId . ') : Erreur enregistrement stock <br>';
}
}
}
}
}
echo '<br><br><br><br>---MAJ TERMINEE---';
function getIdByUPC($id_product, $reference)
{
if (empty($reference)) {
return 0;
}
$query = new DbQuery();
$query->select('pa.id_product_attribute');
$query->from('product_attribute', 'pa');
$query->where('pa.upc LIKE \'%' . pSQL($reference) . '%\'');
$query->where('pa.id_product = ' . (int) $id_product);
return Db::getInstance(_PS_USE_SQL_SLAVE_)->getValue($query);
}
function getIdProductByUPC($reference)
{
if (empty($reference))
return 0;
$query = new DbQuery();
$query->select('pa.id_product');
$query->from('product_attribute', 'pa');
$query->where('pa.upc = \'' . pSQL($reference) . '\'');
return Db::getInstance(_PS_USE_SQL_SLAVE_)->getValue($query);
}
?>

Answer 2

I think, line $productId = Product::getIdByUPC($reference) is wrong.
The correct: $productId = getIdProductByUPC($reference)
