onsubmit_callback help

Hi, i'm trying to use an onsubmit_callback with my data container.

The problem i'm having is actually using the field values in my method:

Code:

---

public function setPeriod(DataContainer $dc)
        {
                if ($dc->type == 'Period')
                {// run code }

---

It is supposed to check if the 'type' field in my dca that has just been submitted has a value of 'Period' before running some code.

How can i use the values of the submitted fields? I can retrieve an id using $dc->id, so I assumed to get the value of a field name you used $dc->field_name but this doesn't seem to be working.

Thanks

I got this figured out now, but it has lead to another problem :)

Is there any way to stop contao from adding the data to the database after the onsubmit_callback has been run?

What is the answer to your original question?

To get the values you use:

Code:

---

$field_value = $dc->activeRecord->field_name;
