The prime purpose of content management systems like Drupal is to make it easier for the end users to create websites. For the developers, customizing the CMS to the specific requirements of the projects is a great way of getting things up and ready quickly and efficiently.
Nodes are a great Drupal feature that organizes and controls the way in which all content within a Drupal website is displayed. All published content pieces are “nodes” that could be individually or collectively created and manipulated. To add a custom content type, a developer only has to create or modify the associated node either through the GUI or programmatically.
In this post, I’ll show you how to programmatically create nodes in Drupal 7 through simple code snippets. Let’s get into it.
Initialize Node Object
The following snippet of code will initialize a node object:
$node = new stdClass(); // We create a new node object $node->type = "page"; // Or any other content type you want $node->title = "Your title goes here"; $node->language = LANGUAGE_NONE; // Or any language code if Locale module is enabled. $node->path = array('alias' => 'your node path'); // Setting a node path node_object_prepare($node); // Set some default values. $node->uid = 1; // Or any id you wish
Note: If you have a multi language site, you will have to enable the locale module and put the code of the language you wish your node to have in place of ‘LANGUAGE_NONE’ for $node->language.
Add Custom Fields
Adding custom fields is easy and could be done through the following snippet:
$node->field_id[LANGUAGE_NONE]['value'] = $modelnumber; $node->field_myfield['en']['value'] = $ENbody; // Add your custom field formats here. $node->field_myfield['nl']['value'] = $NLbody;
Add Files or Images
Images or other file types could be easily added to nodes without much trouble:
// Some file on our system $file_path = drupal_realpath('somefile.png'); // Create a File object $file = (object) array( 'uid' => 1, 'uri' => $file_path, 'filemime' => file_get_mimetype($file_path), 'status' => 1, ); $file = file_copy($file, 'public://'); // Save the file to the root of the files directory. You can specify a subdirectory, for example, 'public://images' $node->field_image[LANGUAGE_NONE] = (array)$file; //associate the file object with the image field:
Add a term to node
You can also add terms to a node for easier categorization. Terms allow developers to improve content categorization and enhance the content search process. Adding terms to nodes requires the following single line of code:
$node->field_tags[$node->language]['tid'] = 1; //1 is the term id being assigned to the field tag (name of term reference field)
Save the node
The only thing remaining now is to save the node created earlier. Here is how to do that:
$node = node_submit($node); // Prepare node for a submit node_save($node); // After this call we'll get a nid
Nodes are a great way of managing content on Drupal website. The best thing is that the developers could easily manage various aspects of nodes pro through simple code snippets. I hope that you could now confidently handle nodes at your Drupal website.
