This is an introductory PHP course.
We are creating a "dynamic" web page without AJAX (JavaScript) since
that will be in the intermediate course.
The site is a single file - index.php. Structured with a table (to avoid
learning CSS at the same time as PHP and SQL) for the header, footer and
three panes in between. The left-most pane is hte navigation, the center
is the Main and the right is the "news".
Each table cell has an include() for another file that makes up the
content of that cell. eg. include("nav.inc.php") for the navigation bar.
The main cell then has some conditional php code to decide on what
include to run, eg, one for "show summary of all recipes", or "show
details for a recipe", or "enter a new recipe/comment", etc. Also, of
course for registering and logging in.
Since I'm trying to display the name of the logged in user on the left
pane, that code is included before I run the code in the "main" cell,
hence my timing problem
THe class example sidesteps it by simply not putting the data in there.
Maybe I should just go back to the class example. Would be a lot less
headache.
