Topic Cloud / list all topics in an issue - Newscoop Support Discussions on Sourcefabric Forum

BAUMANN Thomas

Hi,

is there somebody who could create a "topic" cloud?
I need a solution which creates me a topic list of current issue (and tells me how often is this topic used in current issue).
e.g.

Summer,4,uri-to-search-all-tags-with-summer
Winter,1,uri-to-search-all-tags-with-winter
Spring,4,uri-to-search-all-tags-with-spring

So the user can click on the topic Summer, and gets a list like "topic-cont.tpl" for the clicked topic.

Best regards,
Thomas.

Hi Thomas,

try this approach from our Cookbook - http://en.flossmanuals.net/newscoop-3-cookbook-3-5-2/tag-clouds/

This sounds pretty good, but I need to create a list list_article_topics with constraint to a specific issue.

Which $gimme->topic->XXX shows the issue/section/article number of the specific topic?

(I need an answer to: which topic has which articles).

Best regards!
Thomas.

You can get list of articles that have specific topic(s) this way:

{{ list_articles ignore_issue="true" ignore_section="true" constraints="topic is $topic1 topic is $topic2 matchalltopics" }}

there is also option 'matchanytopic' available

(more details here: https://wiki.sourcefabric.org/display/NsLingo/article_constraint)

Hi ljuba,
i tried to output this list, but it seems the list is empty. (But {{ list_article_topics }} shows me a list).
How can I debug, why list_articles with constraint to topic is empty.

I do following:

{{* write all topics to an array *}}
        {{ list_article_topics }}
                {{ $array[$gimme->topic->name]['id'] = $gimme->topic->id }}
                {{ $array[$gimme->topic->name]['name'] = $gimme->topic->name }}
                {{ $array[$gimme->topic->name]['count'] = $array[$gimme->topic->name]['count'] + 1 }}
        {{ /list_article_topics }}

{{* show count of topics and articles with this topic *}}
        {{$count=0}}
        {{foreach from=$array item=item}}
        {{if $count == 0}}<p>{{ /if }}{{$count=$count+1}}
        <a href="{{ url options="template topic.tpl" }}&tpid={{$item['id']}}">{{$item['name']}}</a> ({{$item['count']}}){{ if $count == count($array) }}{{ else }}, {{ /if }}
                {{ list_articles ignore_issue="false" ignore_section="true" constraints="topic is $item['name'] matchAnyTopic"}}
                        <h6>[{{$count}}]<a href="{{ $gimme->article->url }}" title="{{ $gimme->article->title }}">{{ $gimme->article->title }}</a></h6>

                {{/list_articles}}
        {{/foreach}}<br />

Any help is appreciated.

Current Output is:

Endpoint Security (1), IBM Tivoli (3), Security (1), Monitoring (1), Software (3), Mobile Device (1), Microsoft Windows (1), Linux (1), UNIX/AIX (1), Veranstaltungen (1), Events (1), Mitarbeiter (2), Partner (1), Backup/Recovery (1), HA (1), Loadbalancing (1)

Best regards,
Thomas.

I am not sure but try to add lang parameter after the topic name here

{{ list_articles ignore_issue="false" ignore_section="true" constraints="topic is $item['name']:de matchAnyTopic"}}

The list shows still empty :-(
How can I check further?

I even did following (assign variable testtopic with a defined topic).

                {{assign var=testtopic value="Partner"}}
                {{ list_articles ignore_issue="false" ignore_section="true" constraints="topic is $testtopic matchAnyTopic"}}

<h6>[{{$count}}]<a href="{{ $gimme->article->url }}"
title="{{ $gimme->article->title }}">{{
$gimme->article->title }}</a></h6>
                {{/list_articles}}

But nothing is printed :-(
It seems there is something wrong with the constraints :-(

Or can I use e.g. topicid as constraint? Which constraints are allowed?

Best regards,
Thomas.

Even trying from http://en.flossmanuals.net/newscoop-4-cookbook-en-4-0/template-reference--lists/list-articles-and-article-related-content/ to say

{{ list_articles ignore_issue="true" ignore_section="true" constraints="topic not `Partner` matchAnyTopic"}}

to get articles which dont have a topic "Partner"

the list is still empty.
When removing the constraint, then all articles are printed.

these are all possible constraints inside article list:

name <string_operator> <string_value>
number <integer_operator> <integer_value>
keyword <string_value>
OnFrontPage <switch_operator> <switch_value>
OnSection <switch_operator> <switch_value>
upload_date <date_operator> <date_value>
publish_date <date_operator> <date_value>
public <switch_operator> <switch_value>
type <switch_operator> <article_type>
<article_type> <article_type_attribute> <attribute_type_operator> <attribute_type_value>
matchAllTopics
matchAnyTopic
topic is|not <string_value>
reads <integer_operator> <integer_value>
author <string_operator> <string_value>
issue <integer_operator> <integer_value>
section <integer_operator> <integer_value>
