Project Title: Add variables to a URL in a WordPress site Description: I have a form in my website to book seats in my walking tours. The form is a custom-made plugin that sends the information via API to my booking system. One of the fields is about which hostel/hotel the customer is staying in. I want to be able to give QR codes (links) to the those hotels with the name of the hostel/hotel pre-loaded I am looking for a skilled WordPress developer to assist me in adding variables to the URLs on my WordPress site.

Skills and Experience: - Strong proficiency in WordPress development - Solid understanding of query parameters and URL manipulation - Experience with altering page content based on URL variables - Familiarity with WordPress plugins and their integration - Ability to manually code if necessary, as the preferred method for adding these variables is not decided yet - Good problem-solving skills and attention to detail If you have the necessary skills and experience, please submit your proposal for this project.
