How can I make my own form without a wizard

Question

Hello,
I already created Tabular Forms using the wizard and everything worked. But now I have different requirements on my from. I need some radio buttons and some option buttons (which values come from different tables) and some normal number fields. So I can't no longer use the tabular forms.
I created a table which can save all the information I want to provide by the form. This table has a primary key populated by a sequence I created too. Then I created a page which looks like a questionnaire I got before to design this form.
I added another hidden item (*ID*), which should be filled by my sequence and a button which should do the insert statement.
But I couldn't find out how to do. I looked a the processes which a made when I use the wizard but I'm not sure what they do actually.
My question is, how is it possible to have the hidden item filled with the next primary key of my table and then how do put all the item values of the form in an insert statement? I there maybe a better way to acchieve my goals?
Regards
Felix

If you created your sequence with a trigger (usually APEX creates these together for you) then there is no need to have the next ID number, when you do your insert it will automatically fill this in for you. The trigger will see that you're trying to insert null for the ID and instead replace it with the next number in the sequence.
As for having all your items in an insert statement, you can do this in two ways. One being to create up a DML page process to handle the insert/update/delete statements. You will also need an on load row fetch process to load data onto your form. Make sure your page items are set to Source Type Database Column with the column names in the Source Value field.
The other option is to create custom page processes to do these for you - for example, one process for inserting, one for updating, one for deleting, one for displaying data, and then you can set the condition of each process to only run if a certain button is clicked. This is useful if you have more code to run with each button click.
