Page refresh causes custom meta tags, etc. to disappear

Friday 09 June 2006 1:09:09 pm

For reference, running ez 3.6.3.

Following the directions in ">this post ( http://ez.no/community/forum/developer/meta_description_tag ), I created for the various objects in the system the following fields:
meta keywords
meta description
html page title

In page_head.tpl, the code checks the current node for these fields; if they are present and not empty strings, it uses those values for the meta data and page title. Otherwise, it uses the default behavior of eZ publish. Complete code of page_head.tpl listed below.

Now, it works fine if I flush the cache and load the page up for the first time. The meta tags and page title display as expected. However, any subsequent page loads cause the page to revert back to the default behavior. Throwing in a debug print-out shows that the first page load treats $node as a complete object; any page load after that shows $node to be empty.

Is this a caching (or lack thereof) issue? I don't have a cache block around the inclusion of the page head in pagelayout.tpl. Can't see anything in the log files indicating an error. Stumped on this one.

Thanks in advance.

That did the trick; one more useful bit of info. to file away.

Thanks, Kristof!

Cheers.
