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.
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'Status' and 'Promote' are easy to overlook -- if you don't set those, the node will remain unpublished and unpromoted, and you'll only see if you go to the content administration screen.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.
Make sure the important fields are set: uid, name, type, language, title, body, filter (see node_add() and node_form())
Pass the node through node_object_prepare() so other modules can add to the $node object.
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.

Here is a snippet of the xml I am working with:
My example xml
A client requested that we add the ability to filter which type of "news articles" are displayed on specific pages. They create these articles on another website, where they now have the ability to assign a one or more categories to each of the articles. We load the articles via php and xml.
The error I receive is:
Call to a member function getElementsByTagName() on null in ...
Here is the code from 2012 that I am working with:
$item = $dom_object->getElementsByTagName("Releases");
foreach( $item as $value )
{
$Release = $value->getElementsByTagName("Release");
foreach($Release as $ind_Release){
$Title = $ind_Release->getElementsByTagName("Title");
$PublishDateUtc = $ind_Release->getAttribute('PublishDateUtc');
$DetailUrl = $ind_Release->getAttribute('DetailUrl');
$parts = explode('/', $DetailUrl);
$last = end($parts);
I am trying to transverse to the category code and set a variable with:
$newsCategory = $ind_Release->getElementsByTagName("Categories")->item(0)->getElementsByTagName("Category")->item(0)->getElementsByTagName("Code")->item(0)->nodeValue;
This loads the current 2018 articles with the category slug being echoed, because they have an assigned category, but it fails to load 2017, 2016, and so on, I believe, because they are not assigned a category within the XML and this is breaking something.
A news article without a category appears with an empty categories node within XML
I understand that I am using getElementsByTagName, and because there is no element beyond the first categories node it breaks.
Is there a way to check that there is indeed a path to Categories->Category->Code[CDATA] before trying to set it as a variable and breaking it?
I apologize if this is confusing, I am not a PHP expert and could use all the help I can get. Is there a better way to transverse to the needed node?
Thanks.
You need to use XPath. If you're using DOMDocument, this is done via DOMXpath.
Your current approach uses chaining, and the problem with chaining is it breaks down if a particular juncture of it doesn't return what the following method relies on. Hence your error.
Instead, check the whole path from the start:
$domxp = new DOMXpath($dom_object);
$node = $domxp->query('/Categories[1]/Category[1]/Code[1]');
if (count($node)) {
//found - do something
}
i am new to typo3, so sorry, if this is too obvious.
I do not expect a complete solution, just the topics i would need to read about in order to solve the task would be perfectly enough. :)
Here the task:
I have a typo 3 installation with job advertisements in it. Now the company wants to publish that data in to a social website, which needs to have the job advertisement data put on a server in an xml feed, which looks like this: http://www.kununu.com/docs#jobfeed. Don't worry about what it says in there, it's just stuff like Job Title, Description etc.
Like i said, i am completely new to this and just have a vague idea.
My thoughts so far were something like this:
I probably need to write a plugin, which pulls the data out of typo3 by the push of a button
That Plugin need to establish a database connection to pull the data (probably it's mysql, but i am not entirely sure yet)
The data need to be formatted, which is either done by some string operations or by some kind of xml handler i assume.
Sidenote: I read something about TypoScript, but i'd like to avoid that, since it's a one time project and probably not worth the time to learn it. For me at least.
Thank you loads for your help in advance.
Cheers
you can handle that (basicly with typoscript). The other part has to come from PHP (F.e. extbase plugin) ... First part creates the XML output. Second part uses my Demo plugin to include data (Pages+special fields) from DB.
Within TS we are able to create a new typeNum. With that you can call your XML. ( ?type=1234 ) Within the BE you can select each page for output.
If you need help just contact me. I would send you the plugin.
sitemap = PAGE
sitemap {
typeNum = 1234
config {
# Set charset to utf-8
metaCharset = utf-8
# Deactivate TYPO3 Header Code
disableAllHeaderCode = 1
# Content-type settings
additionalHeaders = Content-type:text/xml;charset=utf-8
# Do not cache the page
no_cache = 1
# No xhtml cleaning trough TYPO3
xhtml_cleaning = 0
}
10 = USER_INT
10 {
userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
pluginName = Sitemap
extensionName = Srcxmlprovider
controller = Sitemap
vendorName = Sourcecrew
action = exportXml
switchableControllerActions {
Sitemap {
1 = exportXml
}
}
}
}
Ich habe die EXT noch schnell ins TER gepushed. Ein Tutorial liegt innerhalb.

I am very new to Drupal. I need to develop a site using this CMS. I can understand creating content as an admin. But I would like to create content from code. For example I want to create articles in the backend programmatically without publishing them. So that site admin can review and publish them if he wants to. Tasks like these.Are there any references for programmers? About the structure of drupal code and where to write what things like that. Not videos I can't watch them in office.
Custom code in Drupal is generally done with the help of modules.
One way to familiarize yourself with the Drupal API could be to install the Examples.
In your Google searches, go for tutorials about writing your own modules.
THis being said, saving a node programmatically is fairly straightforward & I doubt you will have problems finding out how to do it.
Your main problem is to understand the "Drupal Way".
You can check excellent resources such as
- buildamodule.com
- drupalize.me
SOLUTION !
You can use below code to create a node programatically with drupal,
$node = new stdClass(); // Create a new node object
$node->type = 'YOUR_CONTENT_TYPE';
node_object_prepare($node); // Set some default values
$node->language = LANGUAGE_NONE;
$node->status = 0; // un-published
$node->uid = 'USER_ID';
$node->title = 'YOUR_TITLE';
$node->body['und'][0]['value'] = 'YOUR_DESCRIPTION';
$node->body['und'][0]['summary'] = 'YOUR_SHORT_DESCRIPTION';
$node->body['und'][0]['format'] = 'filtered_html';
$node = node_submit($node); //prepare node for saving
node_save($node); // save node
I'm trying to create a function to retrieve and display just the Body field of a Drupal node, based on a given URL.
Currently, I've extended the functionality of the standard Drupal RSS to do a detection method. This will happen if you enter the following url:
http://mysite.com/rss.xml/page=54
That last part is critical - it tells what node ID to load from. As far as code goes, I've modified the node_feed() function in /modules/node/node.module to do the following:
if (stristr($nids, 'page=') !== FALSE) {
$nid = substr($nids, stripos($nids, 'page=') + 5);
$result = NULL;
if ((string)(int)$nid === $nid) {
$result = db_result(db_query("SELECT `nid` FROM {node} WHERE `nid` = %s AND `type` = 'flashnode'", $nid));
}
if ($result) {
$item = node_load($result);
print($item->body);
}
exit;
}
While this works, we're worried about it for two reasons:
1) Do the results cache? This is a very heavy-load page that will be called a lot.
2) Is there an "official" way to do this? One that uses modules with caching, instead of a semi-hacky workaround?
Thanks in advance for any guidance.

You should definitely not be hacking apart the RSS feed in order to create a URL that returns a node's body. You should create a very simple custom module: http://drupal.org/developing/modules
The Drupal module system is lets you set up a url so that something like /fetch_body/1234 calls the fetch_body() function with $nid=1234 as the parameter. As for caching, you have a lot of options in your custom module. The most obvious would be to use cache_get() and cache_set() to do simple caching on your own based on the node ID.
What version of Drupal are you using? I would highly recommend the book Pro Drupal Development, just make sure to get the edition that matches your drupal version.
I've recently started developing a portfolio website which I would like to link to my wordpress blog using simplepie. It's been quite a smooth process so far - loading names and descriptions of posts, and linking them to the full post was quite easy. However, I would like the option to render the posts in my own website as well. Getting the full content of a given post is simple, but what I would like to do is provide a list of recent posts which link to a php page on my portfolio website that takes a GET variable of some sort to identify the post, so that I can render the full content there.
That's where I've run into problems - there doesn't seem to be any way to look up a post according to a specific id or name or similar. Is there any way I can pull some unique identifier from a post object on one page, then pass the identifier to another page and look up the specific post there? If that's impossible, is there any way for me to simply pass the entire post object, or temporarily store it somewhere so it can be used by the other page?
Thank you for your time.
I stumbled across your question looking for something else about simplepie. But I do work with an identifier while using simplepie. So this seems to be the answer to your question:
My getFeedPosts-function in PHP looks like this:
public function getFeedPosts($numberPosts = null) {
$feed = new SimplePie(); // default options
$feed->set_feed_url('http://yourname.blogspot.com'); // Set the feed
$feed->enable_cache(true); /* Enable caching */
$feed->set_cache_duration(1800); /* seconds to cache the feed */
$feed->init(); // Run SimplePie.
$feed->handle_content_type();
$allFeeds = array();
$number = $numberPosts>0 ? $numberPosts : 0;
foreach ($feed->get_items(0, $number) as $item) {
$singleFeed = array(
'author'=>$item->get_author(),
'categories'=>$item->get_categories(),
'copyright'=>$item->get_copyright(),
'content'=>$item->get_content(),
'date'=>$item->get_date("d.m.Y H:i"),
'description'=>$item->get_description(),
'id'=>$item->get_id(),
'latitude'=>$item->get_latitude(),
'longitude'=>$item->get_longitude(),
'permalink'=>$item->get_permalink(),
'title'=>$item->get_title()
);
array_push($allFeeds, $singleFeed);
}
$feed = null;
return json_encode($allFeeds);
}
As you can see, I build a associative array and return it as JSON what makes it really easy using jQuery and ajax (in my case) on the client side.
The 'id' is a unique identifier of every post in my blog. So this is the key to identify the same post also in another function/on another page. You just have to iterate the posts and compare this id. As far as I can see, there is no get_item($ID)-function. There is an get_item($key)-function but it is also just taking out a specific post from the list of all posts by the array-position (which is nearly the same way I suggest).
