Hi Ivan,

I just looked over your post really quickly. But that quick glance makes me think you are need of one or both of the following modules in addition to nodewords:

Hi,

The actual problem is providing an API to let modules add META in a more structured way so that eg. the same META is not sent 2 times or module can decide to concatenate further meta or define a "owerwriteability" level.

I gave a look to nodewords aka Meta tags but I have stuff that aren't nodes (they aren't views or taxonomies either) that don't fit with the node paradigm too well.

nodewords provide a hook to 'prepare' META but it is on a module base. Nodewords needs to be aware of all the content types (or just pages, menu_hook etc...) it can support (*unless I'm missing something...*) but actually what know better which are the most suitable meta for a "content" should be the content producer (be it a "node" or just a MENU_CALLBACK). Other modules like nodewords_bypath and _nodetype do some extrawork to know what actually called the hook. But I'd find myself more comfortable with a different approach: - there is a common API that let me manage META - modules that want to add META use it - when everything is ready drupal_set_html_head get called

The problem is: - the API functions should be ready when other modules call them - drupal_set_html_head($meta) should be called last

If the weight of my meta module is high, other modules won't find the functions. If the weight of my module is low and I put drupal_set_html_head($meta) in the menu hook, drupal_set_html_head will be called before $meta had the chance to be filled by other modules.

Is there a more drupalish way to deal with dependency and "order of execution" in drupal?

Go under administer/themes and there is a section to turn off submitted by.. line for each content type. Thanks! Mark On Jan 4, 2009, at 9:29 AM, Bob Smither wrote:

Dear Group,

Is there a way to remove the "Submitted by ..." line that appears under the title of each page?

I poked around in Administration and could not find a way to do this.

Hi Ivan,

I just looked over your post really quickly. But that quick glance makes me think you are need of one or both of the following modules in addition to nodewords:

http://drupal.org/project/nodewords_bypath http://drupal.org/project/nodewords_nodetype

I did really look in those modules but what I would like to overcome is the need of "knowledge" by nodewords of the "content" that it is going to be displayed (be it a node or "whatever"). What I was thinking is: - having a global object that store what other modules would like to see in the META (+ some logic to decide what actually get in) - having some mechanism that when when all the module got a chance to make a request to the global object will output the META I could think of a hook mechanism that achieve this but it is not as simple and elegant as having 2 modules with different weight: - offering the object - output the META The hook mechanism I'm thinking about is not that different from the one actually used by the above mentioned modules but it is convoluted. I may use nodewords_bypath to add a set of "static" keywords to some content generated by a MENU_CALLBACK, but nodewords_bypath is not aware of the additional information associated with the MENU_CALLBACK that could be used to build up META. So I may think that each module that would like to use nodewords provide a hook that pass some info and then the module try to "guess" which kind of content was being generated and add the meta... but choosing the meta is something that should be contextual to content creation... then an API may have a system to prioritise which META actually get chosen. So back again to the general problem: inter module communication, hooks and dependencies... In module world (out of core) the simplest thing I thought to overcome the workflow/existence of global object problem was to have 2 modules with 2 different weights... The first one will provide the global object (and methods), the second one will trigger an action. While it doesn't look terrible to actively use weights for 2 modules to solve this problem there may be other systems already integrated into drupal to deal with this kind of dependency. Of course if what get into head (drupal_set_html_head()) was a structured object rather than a string... I wouldn't have to think to write a module so that each function can easily modify META... but that's another topic... If there is no core global object and core global workflow and I need one... I wouldn't know how to build it in a module. That's what I'd like to learn. thanks -- Ivan Sergio Borgonovo http://www.webthatworks.it

I think this is a good idea. This will let each module set it's own meta keywords and stuffs, like JS aggregation with drupal_add_js(), something like a meta aggregator hook or function would be great. On Fri, 2009-01-02 at 10:56 -0600, Larry Garfield wrote:

I'd say you're on the right track with a hook. It's probably easier to explain with examples. I'd suggest something like:

hook_meta() { $info['keyword'] = array('foo', 'bar');

$info['some_key'] = 'some value';

return $info; }

hook_meta_alter() { // Because when you have a structured array, an alter hook is so dead simple to add it seems pointless not to. }

yourmodule_preprocess_page(&$vars) { // Invoke hook_meta_info() and the alter hook, get back the data from all modules, // format it, and inject it into the $vars['head'] variable as appropriate. }

Modules that need to do complex logic to figure out what tags to add can do so in their own hook_meta implementations. It also means no module has a hard-dependency on your module or vice versa, weight doesn't matter, and other modules can inject whatever meta tag info they need that you haven't thought of before.

Make sense? (Exact implementation is left as an exercise for the implementer.)
