conditional statement to show a list of articles
I want to do the following:
A user goes to a section and will see the latest articles for that section. But if they click on a specific link from outside of that section, then it will show them just that entry. This is what I have but haven’t quite got it. The problem is when I click on a specific link, I keep seeing the same article despite a different link.
My site here I am trying to do this for News/Events. It works properly for the link in the navigation, but it doesn’t work with the links under the logo.
<txp:article>
<txp:if_article_list>
<txp:article_custom allowoverride="0" form="article-news-events" limit="7" pgonly="0" section="news-events" sort="Posted desc" status="4" />
<txp:else />
<txp:article_custom form="article" limit="1" pgonly="0" section="news-events" status="4" />
</txp:if_article_list>
</txp:article>and the form, article-news-events has this;
<h3><txp:title /></h3>
<txp:body />Offline
Re: conditional statement to show a list of articles
hi dreamer,
there is something conceptually wrong in the code, about how txp:article and txp:article_custom works.
txp:article is context-sensitive, which means it will “react” to the context, like an article list (a section, a category, a search) or an individual article (its permalink), while txp:article_custom isn’t context-sensitive, which means it just brings a list of articles based on the attributes you fed into it.
You may want to try this code (read the comments for more info about how it works)
<txp:if_article_list>
<txp:article allowoverride="0" form="article-news-events" limit="7" />
<!--
You are in an article list, in this case, in the frontpage for section "news-events".
I've changed article to article_custom and removed some attributes
as they were set to their default values.
As you are already in section "news-events", the txp:article will
"know" that, and will then just fetch articles from that section.
-->
<txp:else />
<txp:article form="article" />
<!--
You are in an individual article.
Again, I've changed article to article_custom and removed some attributes
as they were set to their default values.
As you are already at an article's permalink, the txp:article will
"know" that, and will just fetch the corresponding article for that permalink.
-->
</txp:if_article_list>In your original code, the wrapping <txp:article></txp:article> wasn’t necessary, and in fact, wasn’t correct the way it was being used.
Of course, the code I’ve posted above is not the only way to do this.
Let’s see another way: in a similar fashion to your original code, you could have done something like the following:
<txp:article limit="7">
<!--
Let's take advantage of txp:article context-sensitiveness.
The above tag (which is closed at the end of this snippet) will "react"
to the context.
In an article list context, it will fetch 7 articles.
In an individual article context, it will fetch just 1 article, the one corresponding to the URL.
<txp:if_article_list>
<txp:output_form form="article-news-events" />
<!--
You are in an article list, in this case, in frontpage for section "news-events".
For each of the 7 fetched articles, lets use the "article-news-events" form to render them.
-->
<txp:else />
<!-- Individual article -->
<txp:output_form form="article" />
<!--
You are at individul article context, aka permalink.
For the only fetched article, let use the "article" form to render it.
-->
</txp:if_article_list>
</txp:article>I would say that this second snippet, although it should work correct, it feels somewhat wrong. I mean, I just don’t like it…
dreamer, there are even other possible ways to achieve the same result, but first, let’s see if any of those snippets works for you.

Re: conditional statement to show a list of articles
ah….i’ve seen the light. would this be correct as well…. including the <txp:if_individual_article> tags within the <txp:if_article_list> tag?
<txp:if_article_list>
<txp:article allowoverride="0" form="article-news-events" limit="7" pgonly="0" sort="Posted desc" status="4" />
</txp:if_article_list>
<txp:else />
<txp:if_individual_article>
<txp:article form="article" limit="1" pgonly="0" status="4" />
</txp:if_individual_article>Offline
Re: conditional statement to show a list of articles
Not necessarily, and in fact, you ended up with slightly incorrect code: now, you have a “remaining” txp:else.
This are the three “correct” ways:
<txp:if_article_list>
<txp:article allowoverride="0" form="article-news-events" limit="7" pgonly="0" sort="Posted desc" status="4" />
</txp:if_article_list>
<txp:if_individual_article>
<txp:article form="article" limit="1" pgonly="0" status="4" />
</txp:if_individual_article>The above one is a bit suboptimal. It will be checking both things, but just one will be true.
<txp:if_article_list>
<txp:article allowoverride="0" form="article-news-events" limit="7" pgonly="0" sort="Posted desc" status="4" />
<txp:else />
<txp:article form="article" limit="1" pgonly="0" status="4" />
</txp:if_article_list>Now, the above is a bit more correct.
<txp:if_individual_article>
<txp:article form="article" limit="1" pgonly="0" status="4" />
<txp:else />
<txp:article allowoverride="0" form="article-news-events" limit="7" pgonly="0" sort="Posted desc" status="4" />
</txp:if_individual_article>Finally, this last one is the “inverted” way of the previous one.
