So this is the hook for node view later.
function hook_node_view_alter(&$build) {
// Code
}
To use that hook...
/**
* Implements hook_node_view_alter().
*/
function my_module_node_view_alter(&$build) {
// Example of how to create a variable.
$vid = $build['body']['#object']['vid’];
// Create a placeholder for original vid value.
$build['body']['#object']['original_vid'] = $vid;
// Reset the value of vid.
$build['body']['#object']['vid’] = NEW_VALUE;
}
@toptomatotwo its very challenging to learn alone. Fortunately, there are plenty of medium you can use such as Drupal Stackexchange, Drupal forum, Github, and IRC. You can invite some people to have a Google hangout if you want. I am happy to participate in a virtual discussion to learn and help.
