Just tested it – adding $imagick->setImageAlphaChannel(self::ALPHACHANNEL_DEACTIVATE); to the function caused “HTTP error” when uploading the PDF into WordPress, and didn’t generate a thumbnail at all. Used it like this:

add_action('pdf_thumbnails_generate_image_blob', function ($blob, $filename) {

    $imagick = new Imagick();
    $imagick->readImage($filename);
    $imagick->setImageAlphaChannel(self::ALPHACHANNEL_DEACTIVATE);
    $imagick->setIteratorIndex(0);
    $imagick->setImageFormat('jpg');
    return $imagick->getImageBlob();

}, 10, 2);

Also tried setting $imagick->setImageAlphaChannel(11); as per the answer you linked – no HTTP error but still black areas on the generated thumbnails.

Hi Adam,

Have you been able to fix this issue? I’m having the same problem with listing future posts in the correct order – using orderby and order doesn’t work for me either. Using WP 3.4.1

Hi Scribu, thanks for your reply!

I use my code (above) in a custom page template (which is why I’m using get_query_var('page')). Think a portfolio page that I’m trying to display my Work CPT posts on.

EDIT: I changed my code a bit with an exact copy/paste from your article I mentioned above:

[Code moderated as per the Forum Rules. The maximum number of lines of code that you can post in these forums is ten lines. Please use the pastebin]

but that doesn’t work either. I’m not sure I should be using get_query_var('page') or get_query_var('paged')

Same problem here, my code:

<?php $paged = (get_query_var('page')) ? get_query_var('page') : 1; ?>
<?php $work_items = new WP_Query(array( 'post_type' => 'work', 'posts_per_page' => '12', 'paged' => $paged ) ); ?>
<?php while ($work_items->have_posts() ) : $work_items->the_post(); ?>

<div class="col2 work-item">
    <a href="<?php the_permalink(); ?>">
        <img src="<?php the_field('work_overview_thumbnail'); ?>" alt="" />
        <p class="descr"><?php the_field('work_overview_description'); ?> <span><?php the_field('work_client_name'); ?></span></p>
    </a>
</div>

<?php endwhile; ?>

<?php wp_pagenavi(array( 'query' => $work_items )); ?>

Using get_query_var('page') cause it’s a custom page template as explained in this article. Using get_query_var('paged') doesn’t work either.

My permalink structure is just /%postname%/

Has anyone managed to fix this problem?

Hi Johan,

I’m having a problem related to what fireproofsocks posted.

After dragging the widget into active area the whole form in the widget disappears, except Delete/Close/Save buttons. They come back after the widget has been saved.

I can’t make it to work with custom scripts in my theme. I register my scripts in functions.php, like this:

wp_register_script('selectivizr', get_bloginfo('template_directory').'/_assets/js/selectivizr.js', 'jquery');
wp_enqueue_script('selectivizr');

to have them included in wp_head. Then I use wp_enqueue_script("jquery"); in my header.php BEFORE the wp_head but the jQuery is STILL loaded after my scripts anyway.

Registering Google-hosted version of jQuery forced it to load before my registered scripts to make them work properly. However it made the draggable menu items in Appearance/Menus to stop working. Removing the if(!is_admin()) condition fixes the menu problem, but the dashboard items don’t slide down then (there is no jQuery on the page at all).

From what I understand, this function displays the category in the feed, not on the page. It doesn’t return any value.

Anyone?

Looks great, thanks.

However, I have an issue. What I want to achieve is template with a layout (different from the rest of the archives) for these child categories.

Using the plugin and, in my example, category-5.php to achieve the same layout for all child categories, I get the same effect on each of them: the loop seems to return all posts in category 5.

What I need to have is category 6 page to display only category 6 posts etc.

The current query_posts in the template files looks as follows:

query_posts( 'paged=$page&post_per_page=-1&cat=' . get_query_var('cat') );

I assume WordPress takes the 5 ID from the filename, how should I change the query_posts call to achieve the effect I need?

Loops are in different files:

homepage.php: https://tinypaste.com/7217d – the actual homepage template
index.php: https://tinypaste.com/3f32e
page.php: https://tinypaste.com/8d206 – posting in case it can be relevant to the problem.

EDIT: I think it’s worth mentioning that the archives for both categories and tags paginate correctly as well:
https://dev.gentlecode.net/cssshow/wordpress/tag/colors/page/2
https://dev.gentlecode.net/cssshow/wordpress/category/designer/page/2

You can achieve the same thing using query_posts() and wp_reset_query().

That’s the problem. It doesn’t work with query_posts(). It gets really confused. This method was the only one that worked for me.

Well, in that case, make sure the correct loop is executed on /wordpress/page/2. You can add a line like this: echo "in the home loop";.

I think it’s pretty obvious that it doesn’t execute the correct loop on /wordpress/page/2. Otherwise, it wouldn’t display posts from a category that is excluded in that query.

The whole point of this thread is me trying to figure out why it doesn’t execute the correct loop. I reset the query after both loops, everything works great (PageNavi correctly renders 5 links for 5 pages of posts) just not the actual links in the homepage pagination.

The $wp-query stuff comes from the fact that PageNavi doesn’t really work with custom queries, as explained here: https://www.wplover.com/756/how-to-get-custom-wp_query-loop-working-with-pagination-and-wp-pagenavi

Using this tutorial was the only way I managed to even get PageNavi to display correctly.

Thing is, as explained, homepage and blog page use two different loops. So I would expect Page 2 of “blog” loop (/wordpress/blog/page/2) to display blog posts – which happens, all good.

However, homepage has a different loop, so I would expect Page 2 of “homepage” loop (/wordpress/page/2 to display only homepage posts.

Here’s the link to live example: https://dev.gentlecode.net/cssshow/wordpress/

Homepage displays all posts EXCEPT blog category. Blog page displays ONLY posts in blog category.

EDIT: It’s worth mentioning that PageNavi correctly renders the pagination on the homepage (it’s set to show only one posts per page for testing purposes) – there are 5 posts and it correctly displays 5 pages. It just seems to get confused with the URLs.

Thank you, got it working now.

Justine

Thank you very much!

Thanks for all the help, Stvwlf. Here’s the final code I used – it works great:

<?php
   $pageslug = $post->post_name; // name of the page (slug)
   $catslug = get_category_by_slug($pageslug); // get category of the same slug
   $catid = $catslug->term_id;  // get id of this category
   $query= 'cat=' . $catid. '';
   query_posts($query); // run the query
?>
