[RESOLVED] must set and immediately get $_SESSION var - help!!

ppowell

This is an urgent request (as always)


 generate_admin_customer_position_dropdown($customerResult, $customerResult[0]->id);
 print_r($_SESSION["${projectAcronym}_customerSOWObjectArray"]);

This code will generate an HTML dropdown as well as set a $_SESSION variable.

I can verify the function works perfectly and in fact sets the session variable every time. Problem is that I need to set and then IMMEDIATELY get the session variable w/o redirection because redirection is undoable at the portion of the PHP code that this must work in.

What do I do? Each time I try this the session variable is NOT immediately available until a latter iteration renders it available but far too late to be used.

How do I set and then IMMEDIATELY get a SESSION variable? This is an urgent request!!

Thanx
Phil

How do you store the data into the session? More specifically... what does the generate_admin_customer_position_dropdown/b function do?

EDIT: I ask only because you can immediately access data in the $_SESSION superglobal after you set data in it. Example:

<?PHP
session_start();

function mytest($a, $b) {
$_SESSION['table'] = $a . $b;
}

mytest('testing?', ' test successfull.');
echo $_SESSION['table']; // outputs 'testing? test successfull.'
?>

It would take a year to explain it if you're me, so I'll just say this:

It is used to parse through an existing resultset (an object array) and produce an HTML dropdown of particular customers out of the entire resultset of all customers, however, you need to be able to pick out whether or not you've select A particular JOB out of EACH customer, along with other fields, so the only thing I could figure out what to do is to take that information and stuff it into an associative object array (so that you don't have to re-query the information several hundred times PER customer which could be in the hundreds itself, so you'd be querying several hundred THOUSAND times!) - so I loop through the existing resultset ONE time to produce a SESSION variable consisting of an object array associated by customer ID (as key) and an object (as value) consisting of the required properties to ensure whether or not that customer has ONE job you picked per customer.

That's about as good as I can explain it. Bottom line: I have this session variable that I must be able to immediately retrieve. I set it like this in the function:

 $_SESSION["${projectAcronym}_customerSOWObjectArray"] = $customerSOWObjectArray;

And then you leave the function and then you IMMEDIATELY have to get that session variable.

Okay, first of all, looking at your function, don't you return the HTML data you need for the select box, not store it in the session? So you'd want:

	 $output = generate_admin_customer_position_dropdown($customerResult, $customerResult[0]->id);
	 echo $output;

bradgrafelman

Try putting:

print_r($_SESSION["${projectAcronym}_customerSOWObjectArray"]);

inside your function, right before the return (so, at the very end). Do you see the session data you need?

ppowell

Yes, right before the return I see it..

Phil

bradgrafelman

But immediately after you don't? Now I'm really confuzzled...

Hrm. Maybe try.. doing a [man]session_write_close/man and then a session_open() right after that? I really don't know. That's odd.

Perhaps you should just return the value as well as the HTML in an array instead of fighting sessions? So the return value of the function would look like:

Array (
  HTML data in $html,
  the session data
)

Or is this too hard to recode? Sorry, I'm at a loss here.

ppowell

I got it, days later! It was a bit hard to explain but I'll just suffice to say that I recoded the entire function and it works as it should, returning the object array into $_SESSION..
