So here’s my question:
I looped around twice w/ the same student, so I want to nuke his first
iteration and keep the 2nd:
Array ( [0] => 2090 [1] => 684 [2] => 675 [3] => 1000 [4] => 1002 [5] => 642
[6] => [7] => [8] => [9] => [10] => )
Array ( [0] => 2090 [1] => 684 [2] => 675 [3] => 660 [4] => 726 [5] => 706 [6]
=> 1139 [7] => 1191 [8] => 1246 [9] => 810 [10] => 1046 )
My SESSION_VAR is called
$_SESSION[’student_array’]
How would I do a loop that says, if the 1st element = 2090 (in this case),
delete it, but then exit the loop? Also, if it’s only there once, I of course
won’t want to delete it at all…

OOPS! It’s you, Richard!
I said Bev; for some strange reason that’s who I thought you were. I guess if
I’d read the email address… :)
OK, so here’s a question I have now:
My users will be able to cycle back and generate a new set of values for a
row (the 1st dimension of the row is a student’s RECID); I don’t want them to
create another row, but need to either
a) edit the existing row based on the the 1st dimension in the array, or
b) delete the existing row and create a new one
I’m thinking that option B is the way to go, right? Just find the appropriate
row and delete it, then create a row like I normally do?
Thanks,
Bob Patin

Hi Bob,
Good to see you got the handle of php arrays.
Note that what you are creating is a "two dimension" array. A one dimension
array is a simple list, just like what FM's List() function creates, and a
basic Value List. A two dimension array is an array of arrays, like a
spreadsheet, or an FM table. A three dimension array is an array of arrays
with an array as at least one of the elements. An FM table with a repeating
field could be seen as a 3 dimension array.

Hey Bob,
Does anything come out of the session array at all? If not, the session
may not yet be started... Do you call session_start() before doing
anything else with the session? Also, have you declared the
'student_array' element to be an array, like so:
$_SESSION['student_array'] = array();
Once you do that, option one in your question should work just fine...

OK, absolutely last question:
I’m storing the array in a session variable; I tried this:
$_SESSION['student_array'][] = array(…
and I tried this:
$_SESSION[‘student_array[]'] = array(…
but neither of those are correct; how do I add rows to an array stored in
a session var?

Yeah, you need an "as" clause in that foreach:
foreach($_SESSION['student_array'] as $student){
print_r ($student);
}
Howzzat?

I figured a foreach loop would be the way, but this doesn’t run:
foreach($_SESSION['student_array']){
print_r ($_SESSION['student_array']);
}
Missing something obvious, no doubt… ?

I was thinking I was going to initialize the array when the site
loaded, but hadn’t thought about just using isset().
Sometimes the easiest stuff makes me over-complicate…
Now to figure out how to return subsequent rows… ?

I like using isset($someVariable) to check whether something exists.
Avoids all sorts of mess =)
