Please tell me, I want to introduce and customize the search form in all categories and subcategories, in all cities or countries, etc. In order for a user to go to the site, set the necessary parameters and get on the list of ads that are most relevant.
Knowledge in php at the study stage, html and css is another matter, but this is no easier, but the task is and just waits, I can not start the site until everything is set up. How to implement and where should I start, if possible, please give advice.))
In the header, everything except the logo and buttons add an ad, put it in the footer and at this place I want to implement this area with all the necessary parameters
