Drupal function sequence page view

Submitted by Peter on Sun, 2011-10-02 13:15

Drupal:

technology:

Here is sequence information for one of the most commonly questioned areas of Drupal. In what sequence do the node functions work in a page view?

Most modules work on nodes. Most node modules intercept the node edit or view or both. The sequence of node functions for a node view confuse module developers and the people using newly developed modules. There is some documentation on the sequence of some Drupal node hook functions in some situations but not for all functions.

Here is the page view sequence. We are looking at a page showing a node. The log is empty. We hit refresh and Drupal steps through the page view process. This record of function calls includes all the functions in the node module.
