如何在Drupal中的Cron作业中创建节点？

Question

In a custom module for drupal 4.7 I hacked together a node object and passed it to node_save($node) to create nodes. This hack appears to no longer work in drupal 6. While I'm sure this hack could be fixed I'm curious if there is a standard solution to create nodes without a form. In this case the data is pulled in from a custom feed on another website.

Answer 1

The best practices method of making this happen is to utilize drupal_execute. drupal_execute will run standard validation and basic node operations so that things behave the way the system expects. drupal_execute has its quirks and is slightly less intuitive than simply a node_save, but, in Drupal 6, you can utilize drupal_execute in the following fashion.

$form_id = 'xxxx_node_form'; // where xxxx is the node type
$form_state = array();
$form_state['values']['type'] = 'xxxx'; // same as above
$form_state['values']['title'] = 'My Node Title';
// ... repeat for all fields that you need to save
// this is required to get node form submits to work correctly
$form_state['submit_handlers'] = array('node_form_submit');

$node = new stdClass();
// I don't believe anything is required here, though 
// fields did seem to be required in D5

drupal_execute($form_id, $form_state, $node);

node_save() still works fine in Drupal 6; you'll need a couple of specific pieces of data in place to make it work.

$node = new stdClass();
$node->type = 'story';
$node->title = 'This is a title';
$node->body = 'This is the body.';
$node->teaser = 'This is the teaser.';
$node->uid = 1;
$node->status = 1;
$node->promote = 1;

node_save($node);

'Status' and 'Promote' are easy to overlook -- if you don't set those, the node will remain unpublished and unpromoted, and you'll only see if you go to the content administration screen.

I don't know of a standard API for creating a node pragmatically. But this is what I've gleaned from building a module that does what you're trying to do.

1. Make sure the important fields are set: uid, name, type, language, title, body, filter (see node_add() and node_form() )
2. Pass the node through node_object_prepare() so other modules can add to the $node object.

Answer 4

One more answer I discovered was to use the example from the blogapi module in drupal core. The fact that it is in core gives me a bit more confidence that it will continue to work in future versions.

There are some good answers above, but in the specific example of turning an ingested feed item into a node, you could also take the approach of using the simplefeed module ( http://wwww.drupal.org/project/simplefeed ). This module uses the simplepie engine to ingest feeds and turns individual items from each feed into nodes. I realize that this doesn't specifically address the issue of creating nodes from cron, but it might be an easier solution to your problem overall.
