Hi,
I created a custom module and is trying to display a form under settings.
I used:

function custom_module_form($bid = NULL){
    /* Code goes here */
}

but my form just doesn't show up.
It only shows "Save Configuration" and "Reset To Defaults"

Hi!
I am writing a new node type, and I want to put a button to the edit form, which opens an another page (for example an other node's edit form). I don't want to submit the form, because there may be unfilled fields.

I read the form API, but there isn't too much from the buttons... I viewed the node module, because the delete button on the node's core edit form does something like I want. I found this:

Hi,
I'm new to drupal and startet writing my own modules. Now that I have tried the upcoming 5.0 version of drupal I want to continue developing my modules for the new version.

I created a new node type and extended the node form by using the hook_form(). According to http://drupal.org/node/64279 (Converting 4.7.x modules to 5.x) this hook does not seem to have been changed or removed so I thought at least displaying the nodes form should work. But it seems I'm wrong.

Within a module I have hook_settings()... where the form and its values are defined...

Is their any hook I can call when a user changes values on the settings form?

When a user has changed a value I need to call some functionality of another module...

I have built a simple form which seems to be capturing the data ok as I have checked the database that they are inserted correctly. When I tried to edit the form, the form displays default values for each field instead of the data from the database, what could be wrong?
