How to offset or exclude from different categories ?

raminrahimi · 2019-04-21 04:52:35

I’ve three categories (technology, economic, sport)
on the home page, each category has different limit of articles, like:
technology = 4
economic = 6
sport = 3
At the bottom of home page there is an area of More News, here I want to show articles of that three categories except those articles which shows on the top already.
for example:

<txp:article_custom exclude="except_those_which_shows_on_the_top_already" category="technology, economic, sport" ....>

You should be able to do that by storing the already displayed article_id values in a variable and then use that for the exclude attribute. Something like this:

<!-- set the variable once to start with -->
<txp:variable name="featured_articles" value="" />
...
<!-- your technology articles -->
<txp:article_custom section="technology" limit="4" … >
    ...
    <txp:variable name="featured_articles"><txp:variable name="featured_articles" /><txp:article_id />,</txp:variable>
</txp:article_custom>
...
<!-- your economic(s) articles -->
<txp:article_custom section="economic" limit="6" … >
    ...
    <txp:variable name="featured_articles"><txp:variable name="featured_articles" /><txp:article_id />,</txp:variable>
</txp:article_custom>
...
<!-- your sport articles -->
<txp:article_custom section="sport" limit="3" … >
    ...
    <txp:variable name="featured_articles"><txp:variable name="featured_articles" /><txp:article_id />,</txp:variable>
</txp:article_custom>
...
<!-- your "further links" -->
<txp:article_custom exclude='<txp:variable name="featured_articles" />' category="technology,economic,sport" … >
    ...
</txp:article_custom>

In the above the article_id of the 3+6+4 articles shown on the home page is appended to the variable “featured_articles” along with a comma, so that you end up with a comma-separated list of article ids. There’ll be a trailing comma but I think the final article_custom will ignore it.

You can avoid it by using

<txp:variable name="featured_articles" add='<txp:article_id />' separator="," />

instead of

<txp:variable name="featured_articles"><txp:variable name="featured_articles" /><txp:article_id />,</txp:variable>

There is also no need to initialize the variable.

Even better! Then you end up with:

<!-- your technology articles -->
<txp:article_custom section="technology" limit="4" … >
    ...
    <txp:variable name="featured_articles" add='<txp:article_id />' separator="," />
</txp:article_custom>
...
<!-- your economic(s) articles -->
<txp:article_custom section="economic" limit="6" … >
    ...
    <txp:variable name="featured_articles" add='<txp:article_id />' separator="," />
</txp:article_custom>
...
<!-- your sport articles -->
<txp:article_custom section="sport" limit="3" … >
    ...
    <txp:variable name="featured_articles" add='<txp:article_id />' separator="," />
</txp:article_custom>
...
<!-- your "further links" -->
<txp:article_custom exclude='<txp:variable name="featured_articles" />' category="technology,economic,sport" … >
    ...
</txp:article_custom>
