Previously we talked about adding query strings for drupal_goto().
Drupal – Escape the Hex Characters in drupal_goto()
When the form is submitted, we can decide the redirect path in the form_submit() function.
Redirect to node/1 after form submission
function <form id>_submit($form, &$form_state) {
$form_state['redirect'] = 'node/1'
}
A few months ago, i tried to add the latest jQuery to a Drupal 6 website. If you are still working on Drupal 6. Please refer to Drupal – Add Extra jQuery Library.
The approach we used in the above post does not work in Drupal 7 since drupal_set_html_head() has been renamed to drupal_add_html_head() and inline Javascript is no longer supported in this new version. So today i would like to show you another solution which works in Drupal 7.

The EntityFieldQuery does not support any method to select the entities by random. A simple workaround is using the query tag and implement the hook_query_TAG_alter().
Add addTag() in your EntityFieldQuery object.
$query = new EntityFieldQuery();
$query->entityCondition('entity_type', 'node')
->entityCondition('bundle', '<node type>')
->propertyCondition('status', 1)
->addTag('random')
->range(0, 1);

We can add preprocess function for regions such that we can add customization before rendering the region template file(.tpl.php).
Drupal 7 – Check if the current loading page is the node view page of a specific content type
Sometimes we may even want edit the template file(.tpl.php) for specific content such as a content type node view. In Omega theme, there are different regions and by default they will use the following template files.
<drupal>sites/all/themes/omega/omega/templates
I try to preprocess the content region of the Omega theme for a specific content type. So i have to check the content type inside the <subtheme>_alpha_preprocess_region(&$vars) function so that the preprocess modification only applies to that content type. In that case, we could make use of the menu_get_object() provided by the Drupal API.

We have talked about how to disable certain regions using the Context module.
Drupal 7 – Disable certain regions by conditions using Context
But seems that it may not work for certain themes and regions. Luckily, there is another module called Delta which could be served as an alternative. Delta not only could disable the region but it could alter any theme settings for specific context condition. Let’s take a look now.

Context could help you to manage the layout. In the past, i would use the Page manager of Chaos Tool Suite and Panels to control the layout but now i have completely move to the Context module. You can decide which regions should be hidden.
However, i found that it may not work for certain regions and so i raise it in the Context project page. I will keep my eyes on it.

if (in_array($vars['elements']['#region'], array('content', 'menu', 'branding'))) {
switch ($vars['elements']['#region']) {
case 'branding':
$vars['linked_logo_img'] = $vars['logo'] ? l($vars['logo_img'], '<NEW HOME PATH>', array('attributes' => array('rel' => 'home', 'title' => check_plain($vars['site_name'])), 'html' => TRUE)) : '';
