How to create a autocomplete field

You know how to create a module and that it's easier to add a autocomplete field like node reference or user reference to an existing content type with CCK.

When you have your on module you can create an autocomplete field to any field of the database

Node path to path alias array

Convert Drupal node path, "node/123.." to path alias and store it in an array. Useful when you have conditions based on path alias in your module or template files.

<?php
  //Get path alias from arg() function and back to array
  $path = implode('/',arg());
  $path_alias = drupal_get_path_alias($path);
  $arg = explode('/', $path_alias);

  $show_path = array("knowledgebase", "knowledge", "search", "convert", "extract", "password");
  
  if (in_array($arg[0], $show_path)) {
     //Do something...
  }

?>

Add an taxonomy to a certain node type

This code adds a term for each new node of a certain node type based on the title.
It uses a hard coded Vocabulary name and search for its "vid". When the title on the node is changed it changes the terms name as well. When the node is deleted the term is deleted to.

Short condition in PHP

If you want a condition on one row, embedded in HTML this can come handy.

<?php print ($node->body == "") ? $profile_text : variable_get('profile_text', "");?>

Show no result on first load in views

If you want your result list to be empty the first time you load the view, but if you press Apply when filters are set to Any, you want all to be shown, then you can configure it like this.

Add Argument: Global NULL
Mark: Provide default argument
Mark: PHP Code
PHP argument code:

 <?php 
if (count($view->exposed_input)) {
   return FALSE;
}
?> Do not use <?php ?>  

Node API

Some notes on the operations in Drupal 6.x nodeapi hook

Textfield with default value disappearing on focus

If you want a default value disappering from your textfield e.g in a login- or search field you can add javascript to input tag. This is a customized login form to Drupal.

As you can see I changed the name on username field to xyz-name. In my case some script cleared username field, so I changed name and change it back on focus. Maybe there is some better way to do this.

Customize specific blocks

In your themes block.tpl.php you can add a litle script that converts the title to a class to the wrapping div tag. First add the following in a php section:

<?php
$block_class_title = 'block-'.strtolower(str_replace(" ", "-", $block->subject));
?>

It will convert "My Title" to "block-my-title".

Manipulate breadcrumbs

First have a look in your theme settings example.com/admin/build/themes/settings/my_theme.

In Breadcrumb settings you can decide to display breadcrumb and breadcrumb separator. Select if you want to show home page link in breadcrumb and append a separator to the end of the breadcrumb, useful when the breadcrumb is placed just before the title. Append the content title to the end of the breadcrumb
Useful when the breadcrumb is not placed just before the title.
