</fieldset>
</div>
<input type="hidden" name="task" value="" />
<?php echo JHtml::_('form.token'); ?>
</div>
</form>
if the html the action is index.php/view=addstock&layout=edit
Where does the layout edit call to? I had try to locate my entire component I couldn't find any insert SQL.

Answer 1

You cannot see save code as your controller and model extends parent classes.
You can create your own public function save in controller and model or override it.
Basically this is how it works:
Controller method 'Save' is called, which validates data and loads model.
Controller calls Model and pass him valid data.
Model loads JTable, which stores the data and returns true or false
Model returns bool to controller
Controller handles redirect
Classes are located in:
libraries/legacy/controller and libraries/legacy/model

Answer 2

Try to create your component using the Component Creator and see how it does it. It can be a great leaning tool.

Answer 3

simple presave hook:
go to your model and write:
public function save($data){
// do stuff with $data
return parent::save($data);
}
better would be using the prepareTable function:
protected function prepareTable($table)
{
$table->fieldname = 'new_value';
}
