User-Driven Querying PHP / Databases
We explain user-driven querying by introducing how to:
* Pass data from a web browser to a web server.
* Access user data in scripts.
* Secure interactive query systems.
* Query databases with user data.
* Produce one script that contains an HTML <form> and the code that outputs the query results. We call this a combined script.
* Develop results pages with previous page and next page links.
* Use five-step querying to produce components for user input.
