Good day, I would like to commission the connection of a new form on certop.co.uk "certificate form for premises" under the working scripts for payment - przelewy24 and issuance of automatic invoices in ifirma.
1. form I have prepared the issue of plugging under the existing scripts with a slight adjustment, ie, when the payment is completed, we display a different page of thanks depending on the form that was filled out. Currently there is a redirect to one thank you page.
2. php files need to be moved from the theme files folder - to another folder because I may lose php files on wordpress after updating the theme. Site set up in wordpress.
