In order to accomplish this, we used Drupal’s after_build. This allows you to call your own custom function. In this case it calls add_user_location which takes the user’s location and fills in the CCK location fields.

function digitalstax_customizations_form_alter(&$form, $form_state, $form_id) {
if($form_id == 'widget_node_form') {
$form['#after_build'][] = 'add_user_location';
}

function add_user_location(&$form) {
global $user;
$viewinguser = user_load(array(‘uid’ => $user->uid));
$form['locations'][0]['street']['#value'] = $viewinguser->locations[0]['street'];
$form['locations'][0]['city']['#value'] = $viewinguser->locations[0]['city'];
$form['locations'][0]['province']['#value'] = $viewinguser->locations[0]['province'];
$form['locations'][0]['postal_code']['#value'] = $viewinguser->locations[0]['postal_code'];
return $form;
}


$total_amount = $form_values['submitted_tree']['pizza_price'] + $form_values['submitted_tree']['donut_price'];
//Then we have a hidden field with a component ID of 8 and we set it's value like this
$form_values['submitted'][8] = $total_amount;
$form_values['submitted_tree'][8] = $total_amount;


To get the component id, hover over “Edit” next to the component in your list on the webform and the id will be in the url after “components/.”

First, you must add the database to your settings.php file like so:

$db_url['default'] = 'mysqli://user:password@localhost/database_name';
$db_url['external'] = 'mysqli://user:password@localhost/database_name';


So, “default” is our regular Drupal database and “external” is an additional database. To switch to the “external” database, you would use this code:


db_set_active('external');
//Your code here


//*****then remember to SWITCH BACK TO DEFAULT DATABASE when done
db_set_active('default');


Easy as Pie!

In this example we’re returning an array of nids where a field in a CCK content type is equal to the user’s name. This is a rare instance that we won’t go into. But the concept is the same for many other use cases.


global $user;
$nids = array();
$result = db_query("SELECT nid FROM content_type_property WHERE field_propmanager_value = '%s'", $user->name);
while ( $row = db_fetch_array($result) ) {
$nids[] = $row['nid'];
}
return $nids;


In this case, we wanted to remove the button from the node form for a “property” content type.


function digitalstax_customizations_form_alter(&$form, $form_state, $form_id) {
if($form_id=='property_node_form') {
unset ($form['buttons']['preview']);
}
}

To change this, create your own custom module and add the function below. Note that our module is named “digitalstax_customizations” and we wanted the change applied to a view named “admin_dashboard.”


function digitalstax_customizations_form_alter(&$form, $form_state, $form_id) {
if($form_state['view']->name == 'admin_dashboard') {
$form['submit']['#value'] = t('Search');
}
}


This requires the Nodewords module and you’ll need to create a custom module to take advantage of the functionality of the Nodewords API.

The arguments we used in the url for the view are as follows:

• arg 0 is “widgets” or the custom content type.
• arg 1 is the city.
• arg 2 is the state.

So a path would look like this: widgets/springfield/mo

We also included the ability to search all cities in a state by using: widgets/search/mo

Or all of the United States with: widgets/search/us

(This is done simply by replacing the “ALL” wildcard term that Views uses)

Using these arguments from the url, we were able to create meta descriptions and keywords on the fly:

function digitalstax_customizations_nodewords_tags_alter(&$tags, $parameters) {
if(arg(0) == 'widgets') {
if(arg(1) != 'search' && arg(2) != 'us'){
$city = ucwords(str_replace( "-", " ", arg(1)));
$state = strtoupper(str_replace( "-", " ",arg(2)));
$tags['description'] = "Find widgets for sale in " . $city.", ". $state . " at The Widget Place.";
$tags['keywords'] = "". $city .", " . $state . ", widgets, what-nots, the widget place";
}
if(arg(1) == 'search'){
$state = strtoupper(str_replace( "-", " ",arg(2)));
$tags['description'] = "Find widgets for sale in ". $state . " at The Widget Place.";
$tags['keywords'] = "". $state . ", widgets, what-nots, the widget place";
}
if(arg(2) == 'us'){
$tags['description'] = "Find widgets for sale in the United States at The Widget Place.";
$tags['keywords'] = "united states, us, widgets, what-nots, the widget place";
}
}
}

In order to remove it, you must create a module with the following function. Note that our module was named “digitalstax_customizations.”


function digitalstax_customizations_form_alter(&$form, $form_state, $form_id) {
if(isset($form['body_field']['teaser_include'])) {
$form['body_field']['teaser_include']['#access'] = FALSE;
}
}
