Good day. I would like to create an invoicing and quotation software. I’m almost done, but I’ve run into trouble with the printing part, and unfortunately, the older tutorials and projects are not suitable for the new system (see PHPRad). The database connection works, and it inserts items at the end, but the invoice printing is proving to be a challenge. Could you help me by suggesting which lines of code to insert and where? Thank you in advance. Sorry if I categorized it incorrectly.
Please be specific about the error if there is one or is it an implementation issue?
I built my new version of the radsystem studio project rather from the implementation of the older phprad billing projects, and I got stuck at the invoice printing.
