New droplet: Metatag Last Modified

[Argos]

Here's a droplet for use in the metatag LastModifid.

Name: Meta-SiteModified
Description: Create metatag information on when your site was last updated.
Call: [[Meta-SiteModified]]
Code:

Code: [Select]

global $database, $wb;
if (PAGE_ID>0) {
    $query=$database->query("SELECT max(modified_when) FROM ".TABLE_PREFIX."pages");
    $mod_details=$query->fetchRow();
    return date(DATE_RFC822, (int) $mod_details[0])." GMT";    
}
Use:

Code: [Select]


<meta http-equiv="last-modified" content="[[meta-sitemodified]]" />

Could be a part of SimplePageHead.

And simplepagehead should be part of the core!

From a SEO point of view maybe i don't want to have the real last modified presented there
Another question is what happenes whith pages that automatically generates content? Do they ever get updated ?

For example a Startpage that has a news(topics)block presenting the last 5 post right below the normal content. So you have a WYSIWYG block whith an anytopics droplet adding a news section at the end. Anytopics changes the page content every time you post some additional news on you news/topics page but last modified isn't changed at all.

This Droplet is a really nice idea, but far from being something that is feature complete.
Its a special solution for a certain problem and thats what droplets are for.
Good work! 

Personaly i would prefer not having an incomplete metatag presented on PageId 0.

Code: [Select]

global $database, $wb;
if (PAGE_ID>0) {
    $query=$database->query("SELECT max(modified_when) FROM ".TABLE_PREFIX."pages");
    $mod_details=$query->fetchRow();
    return '<meta http-equiv="last-modified" content="'.date(DATE_RFC822, (int) $mod_details[0])." GMT". '" />';   
}

Thanks for your comments and modification NorHei. I didn't really think much about it to be honest, and I'm also not a coder. I just changed the regular SiteModifed droplet to use as a meta tag. Maybe it's quite useless, I don't know. If there a better alternative, or some improvement, I'm happy to hear about it  

I chose for not including the metatag command itself for consistency with other WB metatags like keywords and description. That's why I suggested to use it as:

Code: [Select]


<meta http-equiv="last-modified" content="[[meta-sitemodified]]" />


But of course you can also use it like NorHei suggested.
