CREATE NEW NODE (Basic)	$node_title = 'Article One'; $content_type = 'article'; $node = new stdClass(); $node->type = $content_type; $node->language = LANGUAGE_NONE; // Set default attributes like uid, status, created time etc. node_object_prepare($node); $node->title = $node_title; node_save($node); // Above $node will now be the complete node object. $new_node_id = $node->nid;
CREATE NEW NODE (Associating references)	$node_title = 'Article One'; $content_type = 'article'; $entity_reference_type = 'node'; $entity_reference_id = 4; // Say, node ID 4. $term_reference_id = 4; // Say, term ID 4. $node = new stdClass(); $node->type = $content_type; $node->language = LANGUAGE_NONE; // Set default attributes like uid, status, created time etc. node_object_prepare($node); $node->title = $node_title; //Entity reference field $node->field_my_entity_reference[$node->language][0]['target_id'] = $entity_reference_id; $node->field_my_entity_reference[$node->language][0]['target_type'] = $entity_reference_type; //Term reference field $node->field_my_term_reference[$node->language][0]['tid'] = $term_reference_id; node_save($node); // Above $node will now be the complete node object. $new_node_id = $node->nid;
NODE DELETE (Returns NULL in both the case valid or invalid node ID)	$nid = 4; // Say, node ID 4. node_delete($nid);
DEFINE CONSTANT	const MY_CONSTANT_NAME = 'Drupal Drug'; const MY_SECOND_CONSTANT = 7; Also, check Drupal Constants
GET VARIABLE (Returns variable value OR NULL in case not set)	variable_get('my_module_my_variable'); // Use $default_value if the variable has never been set // Note: $default_value is for current scope it does not set value for future use variable_get('my_module_my_variable', $default_value);
SET VARIABLE (Returns NULL)	variable_set('my_module_my_variable', $value);
DELETE VARIABLE (Returns NULL)	variable_del('my_module_my_variable');
