I'm trying to get my shopping cart items to a pdf to create an invoice
I have url which shows the invoice in html/css like this:
index.php?module=checkout&view=topdf
If I want to get the content of that page to use in mPDF or other pdf libraries using file_get_contents or cURL it doesn't give any content because the url is not an actual file on the server
How can I fix this? I work with templates and don't know how can I export the current php page to a html page
