Drupal 6

I was going through one of my projects and I came to know that how simple it is to insert additional information into your site's search indexes using hook_nodeapi. A comprehensive details about hook_nodeapi can be found here.

Following are the steps involved to make this happen:

• Create a module that implements hook_nodeapi, lets say example_nodeapi()

function example_nodeapi($node, $op) {
  // Function definition here
}

Inside Drupal APIs we can find separate set of APIs that deals with Forms, their elements and properties. Forms API reference guide has all the elements, properties and complete reference to the forms control structure where you can find easily a what properties all forms element carry. For more details please see Forms API Quick Start Guide.

Drupal API provide a hook function hook_block that allow developers to create block or set of blocks their way. hook is a keyword that will replace by the module name, for example example.module file will implement this hook as example_block()

For further details about this hook please visit here

Drupal APIs and Drupal framework allows developer to provide means for other modules to interact or intervene using hooks. This can be done by simply using an API called module_invoke_all(), a comprehensive detail for this function can be found here. Details about hooks in drupal can be found here

Programmatically inserting, editing and deleting a taxonomy term using drupal api is as easy as A,B,C. After scanning taxonomy_term_save() function, it looks like that if we pass an associated array as an argument to this function with proper keys we can make this happen very easily.
