The Bootstrap Process

So George's request for /about-us has been handed to Drupal, and index.php is ready to bootstrap Drupal. What does that mean?

A quick summary

At a code level, we're talking about the drupal_bootstrap function, which lets you pass in a parameter to tell it which level of bootstrap you need. In almost all cases, we want a "full" bootstrap, which usually means "this is a regular page request, nothing weird, so just give me everything."

Output tables with the pager Drupal 7

$per_page = 10;
// Initialize the pager
$current_page = pager_default_initialize(count($rows), $per_page);
// Split your list into page sized chunks
$chunks = array_chunk($rows, $per_page, TRUE);
// Show the appropriate items from the list
$output = theme('table', array('header' => $header, 'rows' => $chunks[$current_page]));
// Show the pager
$output .= theme('pager', array('quantity',count($rows)));

The Request Drupal7

Have you ever wondered how Drupal does what it does? Good, me too. In this series of posts, I'm going to explain what Drupal is doing behind the scenes to perform its magic.

In Part 1, we'll keep it fairly high level and walk through the path a request takes as it moves through Drupal. In later parts, we'll take deeper dives into individual pieces of this process.

Step 0: Some background information

For this example, let's pretend that George, a user of your site, wants to visit your About Us page, which lives at http://oursite/about-us.
