Andreas Tremel	Sunday 28 January 2007 7:31:42 am Hello there! I'm using Exponential v3.8.4. My goal was to render dynamic meta descriptions for each page in the site. Therefore I've created a new attribute and encountered an issue/bug? related to caching: 1. I've defined a new text line attribute named "my_attribute" in the folder class. 2. I created a new folder using "Text" as value for "my_attribute" in the backend. 3. I modified the "page_head.tpl" template like his: <meta name="description" content="{$node.object.data_map.my_attribute.content}" /> When the folder is loaded for the first time in the frontend, the placeholder is filled correctly: <meta name="description" content="Text" /> However, when the page is loaded for the second time, the placeholder is empty: <meta name="description" content="" /> When I clear the site cache, the placeholder works. When the page is reloaded, the placeholder again is empty. Same thing happens when I use another template (e.g. "pagelayout.tpl") or another attribute (e.g. "title"). Has anyone had familiar problems / know a solution? Thank you in advance. Regards, Andreas Tremel
Claudia Kosny	Sunday 28 January 2007 10:59:28 am Hi Andreas The variable $node is not available in pagelayout.tpl and related templates once a page is cached, so if you really need it, fetch the node at the beginning of pagelayout.tpl or page_head.tpl. Check e.g here: http://ez.no/community/forum/install_configuration/no_more_node_variable_in_pagelayout (although this is for EZ 3.9, where $node apparently is not there even for the first page load, the solution is the same).

Hello there!

I'm using Exponential v3.8.4.

My goal was to render dynamic meta descriptions for each page in the site.
Therefore I've created a new attribute and encountered an issue/bug? related to caching:

1. I've defined a new text line attribute named "my_attribute" in the folder class.
2. I created a new folder using "Text" as value for "my_attribute" in the backend.
3. I modified the "page_head.tpl" template like his:

When the folder is loaded for the first time in the frontend, the placeholder is filled correctly:

However, when the page is loaded for the second time, the placeholder is empty:

When I clear the site cache, the placeholder works. When the page is reloaded, the placeholder again is empty.
Same thing happens when I use another template (e.g. "pagelayout.tpl") or another attribute (e.g. "title").

Has anyone had familiar problems / know a solution? Thank you in advance.

Hi Andreas

The variable $node is not available in pagelayout.tpl and related templates once a page is cached, so if you really need it, fetch the node at the beginning of pagelayout.tpl or page_head.tpl. Check e.g here: http://ez.no/community/forum/install_configuration/no_more_node_variable_in_pagelayout
