Need help creating pagination for attachment page!

Thanks for your updates and for all the work you’ve put in to understand the examples and apply them to your application. I know from my own experience how frustrating even “small code” can be.

If it is possible I would like to have a look at your child theme or at least the complete single-attachment.php file. . If you send me your contact information I can give you an e-mail address you can use to send a copy of the file(s). You can use the Contact Us page at the FTJ web site:

Once I see all of the code I will try to work with you to make it work. Thanks for your understanding and your patience.

Thanks for posting your code to Dropbox. I was able to download both of the items and I will have a look at them shortly.

I have installed the Virtue Premium theme and your child theme on one of my test sites and I have had a look at your single-attachment.php template.

Your code uses WordPress functions such as get_the_tags(), which is hard-wired to the built-in WordPress Tags (slug post_tag). Earlier you wrote about “tags I created though the MLA Bulk Editor“. I am guessing that those tags are stored in the “Att. Tags” (slug attachment_tag) added by MLA, which is why they are not returned by this function. When you go to the Media/Assistant Bulk Edit area, does the label above the text area say “Att. Tags” or “Tags”?

You might try something like this:

$posttags = get_the_terms( $post->id, 'attachment_tag' );

The pagination code at the bottom of the template uses calls like get_children() to find the next and previous images in the “gallery”. This is an old WordPress convention that assumes all the images in the gallery are “attached” to the parent post. If you are using an [mla_gallery] shortcode to display a gallery filtered by attachment_tag values, none of this will work.

The best way to work through these issues with you is an e-mail dialog. Please use the Contact Us page at the FTJ web site (Fair Trade Judaica/Contact Us) to give me your contact information so we can continue our communications more easily. Thanks for your understanding.

Thank you for working with me offline to update your product category [mla_gallery] shortcodes and your single-attachment.php template to add “Previous” and “Next” pagination links for the single attachment pages within the product category. Some of the changes are theme-specific, but I am summarizing them here so other users can adapt them to their applications.

The first step is passing the selected tag from the gallery to the attachment page. You must modify the shortcodes in your product category pages to do this. For example:

[mla_gallery tag=ottomans order=ASC mla_caption="{+template:({+title+}|{+caption+}|{+description+})+}" mla_link_href="{+site_url+}?attachment_id={+attachment_ID+}&term_slug={+query:tag+}" size=full posts_per_page=15]

Note the new mla_link_href parameter that adds “term_slug” to the query string.

The next step is adding previous/next link logic to the single-attachment.php template:

<?php if ( isset( $_REQUEST['term_slug'] ) ): ?>
                <nav id="image-navigation" class="navigation" role="navigation"> <span class="previous-image">
                <?php echo do_shortcode('[mla_gallery tag=' . $_REQUEST['term_slug'] . ' order=ASC mla_output="previous_link" mla_link_text="← Previous" mla_link_href={+link_url+}&term_slug={+query:tag+}]')?>
                </span> <span class="next-image">
                <?php echo do_shortcode('[mla_gallery tag=' . $_REQUEST['term_slug'] . ' order=ASC mla_output="next_link" mla_link_text="Next →" mla_link_href={+link_url+}&term_slug={+query:tag+}]')?>
                </span>               </nav>
<!-- #image-navigation -->
<?php else: ?>
                <nav id="image-navigation" class="navigation" role="navigation"> <span class="previous-image">
                <?php previous_image_link( false, __( '← Previous', 'twentytwelve' ) ); ?>
                </span> <span class="next-image">
                <?php next_image_link( false, __( 'Next →', 'twentytwelve' ) ); ?>
                </span> </nav>
<!-- #image-navigation -->
<?php endif; ?>

This code tests for the presence of the “term_slug” and uses a do_shortcode to generate the pagination controls if it is found. If “term_slug” is not found, normal WordPress pagination is performed.

That’s a summary of the solution. I am marking this topic resolved, but please update it or let me know if you have any other problems or questions about adding navigation links using [mla_gallery].

Thank you as well for your positive MLA review and for your donation in support of the plugin and our work. Both are great motivators to keep working on the plugin and supporting its users.
