PHPRunner General questions

Hi, I'm a long time programmer new to PHP and PHPrunner.
Is it possible to have global variables?
In my case I want to filter the where clause based on the user login. So save some parameters into a variable that I can use on multiple pages. The variable is a string that gets built in the "after successful login" event.
ALSO - is there some documentation on programming for PHPrunner or should I be reading up on PHP programming in general? The help file doesn't cover variables etc.
Thanks for your help.

Session variables are what you are looking for.
In the "After successful login" event enter the following code:

$_SESSION['my_custom_var'] = 'My custom value';


In the "Before SQL query" event of a list page, enter the following code:

$strWhereClause = whereAdd($strWhereClause, "you_field_name = '" . $_SESSION['my_custom_var'] . "'");


Replace the "my_custom_var" associative key with a name you like, and replace 'My custom value' with a valid string value.

Thank you Cristian,
I put the following into Login:After Successful Login

$_SESSION['my_custom_var'] = 'My custom value';


Then I tried to test it in table:Before Display

echo "This is a test message to show ... ";

echo($_SESSION['my_custom_var']);

print_r ($_SESSION['my_custom_var']);


The first "test message" was displayed but not the second two messages.
Also

print_r ($_SESSION);

shows a lot of session variables but not my_custom_var
Am I doing this correctly??

echo does not behave like a function. Please, fix your code as follows:

echo "This is a test message to show ... ";

echo $_SESSION['my_custom_var'];

print_r($_SESSION['my_custom_var']);


MAKE SURE TO PERFORM A BUILD OF THE PROJECT!!!

hhhmmm. This works if I set the SESSION in Menu page:Before Display
I can then echo in the table:list page:before display
But if I set the SESSION variable in After Successful Login - nothing!
I've done a full build, logged out/in and restarted Firefox.
So why isn't my SESSION variable saving in After Successful Login??

Do you have a redirection code or something similar in the "After Successful Login" event before the SESSION var?

Yes! I managed to put the function name twice. Fixed now and thank you for all your help.
