Before I get too far into the web pages I am developing, maybe someone could give me some high-level guidance:
1) I have a working site that has a standard page setup. I-Frames run down the left side of the page into which an .asp navigation menu file is loaded. That file in turn loads two .asp files with INCLUDE. I want my new pages to have this same feature, so I would presume I would just echo the code. Is there going to be any conflict between the Server-Side ASP loading and the PHP loading? If my page files have a .php extension, is the order of loading PHP>ASP>HTML?
2) My pages are intended to be somewhat dynamic. I presume I would be using JavaScript to make those aspects happen. Since this is client-side, I can anticipate JavaScript may have limitations changing the way PHP accesses MySQL. I haven't thought this through all the way because I am still wrapping my head around the basic PHP/MySQL concepts; however, is there any advice you can give beforehand regarding integrating JavaScript into my PHP files? A simple example is that the PHP might fetch some MySQL data based on a primary key field value that javascript finds from info elsewhere on the page. Is this question too vague to even respond to?
