Problem with global variables

[Stephane Pointu]

Hi All,

I'm turning mad with global variables...
In created a simple test script with 2 functions which worked fine but the
other one i need doesn't work. Register_global s is On.

Here are the relevant parts of my script:
//Save form data in an array
function add_ota_element s($form_data)
{
$otavars = $GLOBALS["otavars"];
$otavars[ota_name] = $form_data[name];
}
function create_new_gprs _dialup()
{
$otavars = $GLOBALS["otavars"];
echo $otavars[ota_name]; //To see if the form data is well saved
}

switch ($action)
{
case add_ota_element s:
add_ota_element s($form_data);
break;
case create_new_gprs _dialup:
create_new_gprs _dialup();
break;
}

$otavars[ota_name] in the second function is empty. Can anybody explain to
me why it is so. I guess it is related to the switch instruction but i
can't understand why.

Thanks in advance for you help.

The second function is called if the $action is set to
"create_new_gpr s_dialup". This function does not fill the $otavars with
the values from the form as the first function do.

I assume that add_ota_element s() is not called in this case.

When $otavars should be filled in this case? Have you stored the
$otavars into a session? Don't forget that any variable is lost after
the server finished your script, if you didn't save them into a session!

HTH!

I did not put the variable into a session. I thought that i did not have
to as i call the same script... I did not realize that there were two
transactions. Thanks for your answer.
