[Plugin: Widget Logic] Filter function that filters widget content by category

  • Hi!
    I would appreciate help with a filter function that I want to use with widget logic. I’ sure this is rather easy for someone who knows just a little PHP.

    I have added category pages to the navigation bar on my site. Now I would like some of the widgets on these category pages only to display posts that are categorized in the same category as the category page. For instance I want the widget “Recent posts” on the category page “A” only to show recent posts of category “A” and omit posts of all other categories. Widget Logic seams to be a very nice solution for this. But the code I tried to put to gether doesn’t work. Can someone help me with the code?

    function my_filter_function($content='', $widget_id='')
{
global $content;
if (is_category('3'))
  	query_posts($content . 'cat=3');
elseif (is_category('4'))
 	query_posts($content . 'cat=4');
return $content;
$widget_id='recent-posts-4';
}

add_filter('widget_content', 'my_filter_function', 99, 2);

  • instead of using WL to replace the text of a specific widget, try knocking up a PHP widget that only shows recent posts of category X:

    this post here https://forum.bytesforall.com/showthread.php?t=865 has the right idea. all you have to do is replace

    $recentPosts->query('showposts=5&cat=-XX,-YY,-ZZ');
    with
    $recentPosts->query('showposts=5&cat=$cat');

    possibly add a global $cat in there to get the current category.

    good luck

    Hi Alan!
    Thanks for your quick reply and thanks for the great WL plugin.

    Your suggestion works fine for the “recent posts” plugin. What I actually had in mind was a solution to filter a couple of plugins by category, not just the “recent posts”, but also i.e. the “recent comments widget” and the “most popular posts widget”. I thought that a filter in WL could do this, but i realize that this may be much more complicated. To do this with a PHP widget means that one have to get the code and modify it for each plugin and put it in the PHP plugin, I guess. Futher more one need to use one instance of each plugin for each category. That means a lot of instances.
    Is there another way to do this?

    most of what you say is true. but you don’t need one instance of each plugin for each category. you just need to change the code to show the current category, which is in the global $cat.

    Hi Alan!
    Thanks for answering. Yor suggestion sounds smooth. But when I put the code below in the PHP widget, the same recent posts from all categories are displayed in the widget on every page. Any suggestion?

    <ul>
<?php
    global $cat;
    $recentPosts = new WP_Query();
    $recentPosts->query('showposts=5&cat=$cat');
?>
<?php while ($recentPosts->have_posts()) : $recentPosts->the_post(); ?>
    <li><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></li>
<?php endwhile; ?>
</ul>

    /Andreas

    even on category pages?

    you can troubleshoot using echo “current cat ID= $cat” and something like print_r($recentPosts).

    good luck.
