Hi all,

I'm putting up an Exponential site, and I want to add a guestbook. I decided to follow the guestbook tutorial (http://ez.no/developer/ez_publish_3/documentation/building_an_ez_publish_site/the_guestbook), but I have some problems when I press the "Sign the guestbook"-button. The error-messages I get are:
[snip]
Error: eZTemplate
No such attribute for array(4): node_id
Choose one of following: content, path, navigation_part, uri

Error: eZModuleFunctionInfo::execute content::node
Missing parameter 'node_id' for function 'node' in module 'content'
.
.
.
Error: eZTemplate @ design/fairtradenet/templates/pagelayout.tpl:37[14]
Cannot retrieve attribute of a NULL
[/snip]

In this run I'm using different templates than the example. I get the same error when I'm following the tutorial. I have changed the class-id in the form to my guestbook entry class.

I suspect that it doesn't get the values that are submitted, but I've been stuck for two evenings now and I don't have a clue what can be wrong.
Again: I've followed the tutorial, but I get the same error (more or less).

I'm running Exponential 3.2-3 (3.2 release 3) with mysql.

Any help is _very_ appreciated

Sincerely,

Johan Grasmo

Hi,
can you show us your template?
The error complains about some problems with parameters in the template, probably from a fetch function.
Check brackets, commas, quotes and double-quotes in the fetch call...

I've checked a post by Tore Skobba (in this forum), where he has some problems with the $node. I think I have the same problems - do you have any suggestions in how I can fix this ?

Hi Johan

It might look like you are trying to access $node in an template where $node is not available. Try inserting the code below which fetches the node based on "$module_result.node_id" ($module.. is always available):

{let node=fetch(content,node,hash(node_id,$module_result.node_id))}
.... use $node here.
{let}

Thanks Tore.

I think I now know how to work around the quirks in ez.
This should be documented somehow better btw.
