Hi,

I am try to fill sections of the add page as it loads.

In the add page I have student code which is a read only owner id field pulled from session data.
I would then like it to fill a read only box called home group which is pulled from another table called student and the field is home group.
Is this possible? I would like the field visible on the add page or does it need to be handled by events as it is added?
Could I get some help with the syntax for this please?

Graeme,
all you need here is Add OnLoad event.

Select data from the database and assign it to home group field using this code:

global $smarty;

$smarty->assign("value_home_group", $value);


If this doesn't work proceed to Visual Editor and inspect Home group control on Add page in HTML mode to find proper value_... name

The home group field is in a different table table is called student and field is called homegroup than the table this event will write to - so where and what do I put this into?

My apologies - it has been 4 months since I readdressed this project and it is surprising how rusty your skills get.

SO how would you do this as an event so it is unseen by the user?

Graeme,
select a value from your database table and then use the code I provided to put this value to the field.
You need to know some PHP to do this.

A hint please. The smarty stuff is a bit new.
I want to select home group from the table students and insert it into the red only box called homefroup on the edit page which writes to a table called goals.

Graeme,
I gave you the code that deals with smarty.

We don't have a ready to go solution for your task.
Here are some useful links about selecting data from a database table.

In the end I used before add events - it works well without mucking around with smarty code which I couln't get to work and I am out of time.

global $conn;

$strSQLExists = "select * from student where code='".$_SESSION["UserID"]."'";

$rsExists = db_query($strSQLExists,$conn);

$data=db_fetch_array($rsExists);

$values["class"] = $data["form group"];



For anyone else that gets stuck here.
