rdf howto
by David Cohen 26 Jan '11

Is there an easy to follow howto add rdf tags to drupal pages? In particular, I'm trying to add opengraph tags (http://ogp.me/) Wierdly, I find in D7 core one reference to what appears to be an opengraph tag. In profiles/standard/standard.install, there's some code... <code> 'mapping' => array( 'field_image' => array( 'predicates' => array('og:image', 'rdfs:seeAlso'), 'type' => 'rel', ), </code> ...as if it is trying to do exactly what I want, to add og:image data when a node contains an image field. Yet I can find no other code anywhere related to this. Any pointers appreciated. Thanks, -Dave

Taxonomy_select_nodes quetion
by bob brazeau 26 Jan '11

This is for verision 6 of Drupal. I have a taxonomy category with 11 results, but only the top 10 are showing up. I am getting my results by $result = taxonomy_select_nodes(array($tid), 'or', 0, FALSE, 'n.title asc'); Looked into the code for the select http://api.drupal.org/api/drupal/modules--taxonomy--taxonomy.module/functio… and based on my parameters came up with the following query $result = db_query("select distinct(n.nid), n.sticky, n.title, n.created from node n inner join term_node tn on n.vid=tn.vid where tn.tid = %d and n.status = 1 order by n.title asc",$tid); which returns all 11 results. I went into /admin/content/node-settings and upped the value from 10 to 30, but there was no change. Then I changed the FALSE to TRUE in the original code and all 11 results showed up. Not sure why the result set was limited when paging was turned OFF. Can anyone shed light on what was happening there? Thanks, Bob

How to make Dynamic webpage
by Austin Einter 26 Jan '11

26 Jan '11

Hi All I am quite new to Drupal, and trying hard to learn Drupal. My apologize to all, if I am asking a silly question here. I want to implement a dynamic web page for employee work report track purpose using Drupal. 1) At the top of page I want a view (in table format), that will show existing records added. 2) At the center of page I want individual fields where we will enter data for records 3) At the bottom of page I want buttons to add/modify/delete records. Please see the attached word document, what I am trying to make. So individual users can enter data for records and using "add" button I should be able to add the records. With every add/modify/delete operation records shoud be updated in database. Next time user logs in should be able to see previously added records. In Drupal7 what is the best way to do it. Please provide your valuable input earliest. I have thought of below option. Please correct me if I am heading towards wrong direction. a. I will have a panel page and using layout manager will create three regions top, center and buttom. b. In top, I will add the view , center will add the individual fields and at buttom will add buttons. c. I need to explore how to create view, individual text-field/text-areas and buttons and add - If you know it, please let me know. d. And how do I include the database specific code such as INSERT, DELETE etc. Best Regards Austin.

How do I update Drupal7's file list ?
by Greenman 24 Jan '11

24 Jan '11

I keep hitting this problem: I update or move a module and everything breaks. Most of the time the issue is to do with Drupal’s cache of files, objects and includes. How do I update this list ? Unfortunately Drush is even more sensitive to this issue than core, so a drush script is probably not the best way to go. Any ideas on how to re-build the file list ? Peter

I originally needed a random result and the site is only going to have 10 at most so performance is not an issue as this is a light weight marketing site, but I appreciate the DB questioning/ideas on the random issue. blaine

Drupal 7 Entities - view random node
by Blaine Lang 24 Jan '11

24 Jan '11

I have a need for a block that will display a random quote. Node type = 'random_quote' and only 1 random record should be displayed In D7 the body contents are in field_data_body and I have it working using the DB API but it would probably be better using the entityController class methods like 'entity_load' I see that you can pass in conditions but is it possible to return a single random record? Does anyone with more experience with the new EntityController have any recommendations? Thanks!

I have a $node object, in this node there is some fields (Drupal 7). The module works on all contents type, so i do not know what fields the node have. I need to list all fields from a node and get the type of field. Someone can show a example how to do this please? Thanks.

Getting it to work using DBTNG was pretty straight forward and yes, I used the orderRandom() I wanted to use this as an exercise to get to know the EntityController class better. Is it the random requirement that is making that difficult - what if we remove the requirement and just want to return all the records so that I loop thru them (I just need the body field)
