Hi,
I have a recordform with some custom code in the AfterExecuteUpdate event (I'm doing some calculations there to insert those values in a different table).
One of the first things I do in the custom code is to get a variable value:
$thisTourID = $Component->tour_id->GetValue();
I need this value later on in my sql updates.
The record form has 3 listboxes and one of them lists the tour name, based on the value of the tour_id.
Because this recordform does only allow updates (and no inserts) I want to disable these 3 listboxes. I do that with custom code in the BeforeShow event for each listbox entry (and I use a label for each listbox):
e.g.: $Component->Attributes->SetValue('DisableDropDownTour', 'disabled');
If I do so my $thisTourID variable won't deliver the correct value (in fact, no value at all).
So I removed the the custom code for the tour_id listbox and now I'm retrieving the correct value.
I'm now thinking about a different approach:
Put the disable code for all listboxes in the Before Show event of the record form (of course I'd have the SetValue lines to $Component->tour_id->Attributes...) and at the beginning of this code block I'd get the tour_id and save it into a different variable (e.g. globalTourID).
It would look like this:
$thisTourID = $Component->tour_id->GetValue();
$globalTourID = $thisTourID;
$Component->tour_id->Attributes->SetValue('DisableDropDownTour', 'disabled');
In my understanding I now still have a correct value from tour_id in the $globalTourID variable and it wouldn't matter any more that I loose the $thisTourID variable.
The thing is: In my AfterExecuteUpdate event I don't have a value at all if I read out the $globalTourID variable...
Before Show event of the record form:
global $globalTourID;
$globalTourID = $Component->tour_id->GetValue();
echo "<br>" . "Global Tour ID before Show: " . $globalTourID . "<br>";
This echos the correct value when I open the record form.
After Execute Update event of the record form:
echo "<br>" . "Global Tour ID: " . $globalTourID . "<br><br>";
No value is displayed. Somehow this event does not recognize this variable any more?
Regards,
Jack

What is the type of your control ($Component->tour_id)?
A label for example won't be posted back to the server.

It's a listbox (the control type).
The properties-data-settings are:

Sorry Jack,
my look at your code was to hasty.
Try to define
Quote :$globalTourID;
somewhere outside all functions in your ..._events.php file.
Maybe before Quote :function BindEvents() .
