How do I take information from user submitted HTML form and put it on a webpage

[rll18]

So here's what my ultimate goal is. I would like to have an HTML form that has these elements:

Vendor
Amount
Date

(etc...)

I then want these things to be displayed on a separate webpage. (The form I can make, it's the php that I'm having problems with). I want to then be able to use the SAME form to create a NEW invoice (which will be displayed as it's own page). I also want to be able to search for an invoice using any of the fields that were initially input. Am I in over my head for a newbie in php? Any help with the code would be greatly appreciated!!!

What have you done so far? Can you please share your logic (that gave an error)? We can try to improvise in your own approach with the suggestions if applicable for any best practices.

I think if you are a beginner in php or web programming try to search php with sql in google, search for how to create database, how to connect to a database, how to insert data using php with sql, how to update data, how to view data or query data, delete data etc. This are the most important thing you must learn in web programming,
try to watch this tutorials in youtube, or read about what i said.
