Display the content of the node

Wednesday 22 June 2005 6:24:06 am

Hello... A doubt...
I put this code:

{* Fetch node number 42. *}
{let node=fetch( 'content', 'node', hash( 'node_id', 42 ) )}

{* Display the name of the node. *}
{$node.name}

{/let}

But alone this shows me the name of the node... Since I can do in order that it shows the entire content of the node?

Thanks a lot Kristian...

I use this:
{let myvar=fetch(content,node,hash(node_id,115))}
{node_view_gui view=full content_node=$myvar}
{/let}
And works good... It shows the full view of the node but how can i do if i wan to display only the question of the pool (the node is a pool) or the options???

with {$node_name} display the name of the node.. good....but now i put some like this to show only the question of the pool:

{let myvar=fetch(content,node,hash(node_id,115))}
{attribute_view_gui attribute=$node.object.data_map.question content_node=$myvar}
{/let}

But is not work.... do you know how can i do to show for separate the parts of the pool (name, question, options) ???....... help me friend... thanks

Hi Daniel, That sentence shows the question + the options, but i believe that is not way to shows the options and the question for separate...... thanks a lot friend.

Hi Leonardo,

I hope I get you right. It's pretty early in the morning and my coffee didn't done its job yet.

Instead of using a fix id in your template you could use a variable, too. Your code than would look like that.

{default pollNodeID = 115}

(...some other code ...)

{let myvar=fetch(content,node,hash(node_id,$pollNodeID))}
{attribute_view_gui attribute=$myvar.object.data_map.question}
{/let}
{/default}

Actually this isn't pretty much the same as you've got before. But instead of {default pollNodeID = 115} you could do some other things, too:

Get the NodeID from a ini-file named polls.ini:

{default pollNodeID = ezini( 'Polls', 'CurrentPollNodeID', 'polls.ini' )}

Get the NodeID what is specified in the address (e.g. /content/view/full/2/poll_id/117):

{default pollNodeID = $view_parameters.poll_id}

Get the NodeID depending on the current node we're watching (e.g. by visiting node /content/view/full/117):

{default pollNodeID = $node.node_id}

The same like last one, but you include this code outside of $modules_result.content (e.g directly in pagelayout.tpl):

{default pollNodeID = $module_result.node_id}

Get the NodeID of the last poll that was published (and this one is probably the answer to your question):

{default pollNodeID = fetch('content','tree',hash(parent_node_id,2,
                                   sort_by,array(published,true()),
                                   class_filter_type,include,
                                   class_filter_array,array(27),
                                   limit,1)).0.node_id}


------
or even better:
------

{let myvar=fetch('content','tree',hash(parent_node_id,2,
                                   sort_by,array(published,true()),
                                   class_filter_type,include,
                                   class_filter_array,array(27),
                                   limit,1)).0}
{$myvar.object.data_map.question.content.name|wash( xhtml )}
{/let}

I hope the examples are working - if not: blame the coffee and not me ;)

Hi Leonardo,

the file poll.ini does not exists. If you want to use this, you need to create it first. The content of it would look like this:

[Polls]
CurrentPollNodeID=115

But you probably don't want to use this solution, as you still have to set the id by hand after publishing a new poll.

As the examples work for me, I suggest you post the complete code of your template and tell me where and when it is included in your templates.

Hi Leonardo,

back to the problem with the last published poll...

Assuming you place your polls like this:

- Content-Root - NodeID: 2
-- Polls - NodeID: 100
--- Like my page? - NodeID: 110
--- How old are you? - NodeID: 120
--- ...

In this case you can get the last published poll with this code:

{default PollPlaceID=100
         PollClassIDs=array(27)
         currentPoll=fetch('content','tree',hash(parent_node_id,$PollPlaceID,
                                   sort_by,array(published,true()),
                                   class_filter_type,include,
                                   class_filter_array,$PollClassIDs,
                                   limit,1)).0}

Current poll's name is: 
{$currentPoll.object.name|wash( xhtml )}
{/default}

Where:
PollPlaceID: Has to be somewhere obove the place where all your polls are stored (in my example 2 or 100)
PollClassIDs: An array of classes you use for your polls. The default poll-class that comes with eZ publish should have the ID 27. If you created other poll-classes, just add them like this: array(27,50,99,500)

----------------------------------

According to the user-name-problem:
The code you provided is correct for that purpose. The problem you described may occur, if you use that code in override-templates. I discovered similar problems with override templates and wrong variables in the past (with eZ publish < v3.4.0). Maybe it helps if you do not make use of a {let}:

{fetch('user','current_user').contentobject.name}

---------------------

I think in your last question you ask how to give a user the possibility to logout. You can do this either with a simple link or with a button.

Link:

<a href={"/user/logout"|ezurl}>{'Logout'|i18n( 'design/standard/toolbar' )}</a>

Button:

<form name="logout" method="post" action={"/user/logout"|ezurl}>
<input name="LogoutButton" type="submit" value="{'Logout'|i18n( 'design/standard/toolbar' )}">
</form>

As you can see: The best way to logout a user is to redirect him to "index.php/user/logout".

-----------------

Don't worry about your english - actually mine isn't perfect, too.

Greetings, Daniel.

About the button to log out the users its works perfect really thanks a lot my friend! I'm learning enough things thanks to you...

the module of the polls still have a problem, i was studying the code that you gave me and i understand good it... but it shows the first poll publicated in the Polls Folder (the name of the poll is "Pi" ezpublish takes it as default) i dont know what its happen... i modified the order to sort the polls in the admin interface but it still shows the "Pi" poll...
