Woocommerce Product Updater

To solve this problem, you need a solution that automates the process of downloading the CSV file from your supplier's FTP server, comparing it with your current WooCommerce product data, and updating only the products that have had changes in stock levels or prices. Here is a proposed solution:

Tools Needed:

1. WooCommerce REST API: To interact with your WooCommerce store programmatically.
2. Python: For scripting the automation process.
3. Scheduled Task/Job Scheduler: To run the script at regular intervals (e.g., cron job for Unix/Linux, Task Scheduler for Windows).

Steps to Implement the Solution:

1. Set Up Access to FTP Server:

   • Use Python's ftplib library to connect to the supplier's FTP server and download the CSV file.

2. Process the CSV File:

   • Use pandas or csv library in Python to read the CSV file and store it in a DataFrame or dictionary for easy comparison.

3. Compare with Existing Product Data:

   • Use WooCommerce REST API to fetch current product data from your site.
   • Compare the stock levels and prices from the downloaded CSV with the current data on your WooCommerce store.

4. Update Changed Products:

   • Use WooCommerce REST API to update only the products that have changes in stock levels or prices.

5. Schedule the Script:

   • Use a cron job (Linux) or Task Scheduler (Windows) to run the script at the desired intervals (e.g., twice a day).

Example Python Script:

Here is a simplified example of how the script might look:

python

Copy code

import ftplib
import pandas as pd
import requests
import json
from woocommerce import API

# WooCommerce API credentials
wcapi = API(
url="https://your-woocommerce-site.com",
consumer_key="ck_your_consumer_key",
consumer_secret="cs_your_consumer_secret",
version="wc/v3"
)

# FTP server credentials
ftp_server = "ftp.supplier.com"
ftp_user = "username"
ftp_password = "password"
remote_file = "supplier_data.csv"
local_file = "local_supplier_data.csv"

# Download file from FTP
def download_csv():
with ftplib.FTP(ftp_server) as ftp:
ftp.login(user=ftp_user, passwd=ftp_password)
with open(local_file, 'wb') as f:
ftp.retrbinary(f'RETR {remotes_file}', f.write)

# Update WooCommerce products
def update_products():
# Read the downloaded CSV file
supplier_data = pd.read_csv(local_file)

for index, row in supplier_data.iterrows():
product_id = row['product_id']
new_stock = row['stock']
new_price = row['price']

# Fetch current product data from WooCommerce
product = wcapi.get(f"products/{product_id}").json()
current_stock = product['stock_quantity']
current_price = product['price']

# Check for changes
if new_stock != current_stock or new_price != current_price:
data = {
"stock_quantity": new_stock,
"regular_price": str(new_price)
}
wcapi.put(f"products/{product_id}", data)

# Main function
if __name__ == "__main__":
download_csv()
update_products()


Scheduling the Script:

For Linux (using cron):

1. Open the crontab file:
   sh

   Copy code

   crontab -e

2. Add the following line to run the script twice a day:
   sh

   Copy code

   0 0,12 * * * /usr/bin/python3 /path/to/your_script.py


For Windows (using Task Scheduler):

1. Open Task Scheduler and create a new task.
2. Set the trigger to run twice a day.
3. Set the action to run the Python script with the Python interpreter.

Conclusion:

This solution leverages Python and the WooCommerce REST API to automate the update process. Once set up, it will run at the specified intervals, download the latest CSV file, compare it with the current data, and update only the products that have changed, ensuring your WooCommerce site always reflects the latest stock levels and prices from your supplier.
