Export OSCommerce 2.2 Catalog to CSV and import to Prestashop 1.6+

1. Requirements

First of all your manufacturers must be already in your Prestashop store, with the same name as exists in your OSCommerce store.

Data export format

Data columns to export:

'p' is products table alias, 'pd' is products_description alias

- p.products_id
- p.products_code
- pd.products_name
- pd.products_description
- p.products_price
- p.products_quantity
- p.products_image

2. SQL for export data from OSCommerce

Product data

The data is ordered by Manufacturer name, product code and product name columns in Ascending order.

1. Execute the query on your OSCommerce Database

   SELECT m.manufacturers_name, p.products_id, p.products_code, pd.products_name, pd.products_description, p.products_price, p.products_quantity, p.products_image FROM products p LEFT JOIN products_description pd ON pd.products_id = p.products_id LEFT JOIN manufacturers m ON m.manufacturers_id = p.manufacturers_id WHERE p.products_status <> 0 ORDER BY m.manufacturers_name, p.products_code, pd.products_name ASC

2. Save the result as CSV with name products.csv inside the import_from_oscommerce script folder.

   IMPORTANT Export in CSV with the colum names on first row, use (options from phpmyadmin):

    Columns separated with: ;
    Columns enclosed with:  "
    Columns escaped with:   \
    Replace NULL with:      NULL
   

3. Import process

Import steps executed by script import.php or import-web.php:

1. Creates a multi dimensional array with key = manufacturer name and value as an array with all products from that manufacturer;
2. Traverse the created array, find the Manufacturer from Prestashop base, save its ID for futher use
3. For each product of the manufacturer found Create the Prestashop Product instance, persist it; Load the image from OSCommerce url that points to products_image value; Persist the image to Prestashop base relative to the persisted product;

3.1 How to Import the data

1. Run import.php via SSH or, if no SSH session, run import-web.php from your browser
2. Run categorize.php via SSH or, if no SSJ session, run categorize-web.php from your browser

3.2 Steps to rerun the import (if needed)

2. Truncate poducts table in MySQL DB TRUNCATE ps_product; TRUNCATE ps_product_attachment; TRUNCATE ps_product_attribute; TRUNCATE ps_product_attribute_combination; TRUNCATE ps_product_attribute_image; TRUNCATE ps_product_attribute_shop; TRUNCATE ps_product_carrier; TRUNCATE ps_product_comment; TRUNCATE ps_product_comment_criterion_product; TRUNCATE ps_product_comment_grade; TRUNCATE ps_product_comment_report; TRUNCATE ps_product_comment_usefulness; TRUNCATE ps_product_country_tax; TRUNCATE ps_product_download; TRUNCATE ps_product_group_reduction_cache; TRUNCATE ps_product_lang; TRUNCATE ps_product_sale; TRUNCATE ps_product_shop; TRUNCATE ps_product_supplier; TRUNCATE ps_product_tag;
