mental note on drupal form coding

This is a mental note for me to do. I need to make a summary of what are the things that i've learnt when developing form in drupal. Until now, i can only summarise that there are too many complex commands that require me to understand. So it's better if i can summarise them all in a single illustration so that it's easier to mentally digest.

Writing drupal module - Form creation

After 3 days have passed, i finally able to continue my drupal module coding. Today, what i did is creating form elements inside drupal site.

The order of creating form in drupal is like this:

1. use command 'page callback' where its value is the key function in drupal called drupal_get_form()
   
2. use command 'page arguments' whose value is an array that contains a value referring to a name of function (must use underscore in a single word, eg: nama_saya_shahrul. this value - nama_saya_shahrul will be passed to key function drupal_get_form() for drupal to process the form.
   
3. Create function nama_saya_shahrul($form, &$form_state), this is just an example.
   
4. use variable array that has the followings (make sure you never miss out the hash)
   
   
   
   
   • #type
     
   • #title
     
   • #description
     
   • #default_value
     
   • #size
     
   • #maxlength
     
   • #required
     
   
   
5. Need to use another drupal-specific function called variable_get('nama_textfield',default-value). I think variable_get() is similar to session() or assigning value to hidden form field where we can retrieve them later on.
   
6. last but not least is using system_settings_form($form) function.
