Hello, again. I'm having more issues with my script entering info into my database. The script below grabs a page, strips down the necessary info, then downloads the related image file. After that, it is supposed to enter the information gleaned from the URL into the database. For some reason, the script seems to iterate through the URLs, as I get downloaded images for each URL, but each URL's product is not entered into the database. The script will insert the first product's categories and product info, and then it just stops, and continues to download images.
Any suggestions?
