DMS 2 How can I hook something to a post (e.g. before or after title) on a loop?

[ketri 7]

Hi

I'm using Types -plugin to add a field where the site owner can upload a PDF to each post. 
On a category page I want to show the titles of the posts as links to these PDFs. The articles are only for pdfs, there is no content, exceprt, thumbnails etc. ever.

So I should probably use a hook to insert a link to the PDF on the archive pages. I've tried using

 

add_action('the_post', 'postFunction', 10);

    function postFunction() { 

      echo "<h1>pdf link here</h1>";

}

Just to get me started before I figure out the details of what to add. It now adds the code before the title on archive pages. But it also adds that code pretty much everywhere. https://www.dropbox.com/s/0p70s2h3sx0pjj0/Screenshot%202014-08-20%2010.07.31.png

 

So how can I use a hook to add something to category pages?
I'd also like to remove the title/link to the actual post, and the read more button.

Thank you!

Another option would be to remove the loop from archive-pages and use  custom code a section (or even use NextBox?) to list the pdfs (custom fields) of all the posts in this category. 
I think this might be a better solution for this particular problem.

Hi Ketri,

 

If you want to use a hook and have that hook only display on a category or archive page, you will need to use the WordPress functions below inside your hook.

 

http://codex.wordpress.org/Function_Reference/is_category

http://codex.wordpress.org/Function_Reference/is_archive

 

However, if you want to only display certain information i.e. no content, feature images, excerpts etc... then you don't really need the WP-Content/PostLoop section. You will probably want to create your own section, that way you have much more control over the structure.

The problem with for example this code:

add_action('the_post', 'postFunction', 10);
    function postFunction() { 
      if(is_category()){
      echo "<h1>pdf link here</h1>";
      }
}

is that it loads it everywhere else outside the main loop, in the header, in the menu, in the sidebar etc.

Indeed a custom section seems smarter. I'll see if I can code one myself but it's possible that I'll need the basic structure for a custom section that works as a loop for an archive.

Two questions.

1. I see there is  

pagelines_register_hook( 'pagelines_loop_before_excerpt', 'theloop' ); // Hook

Still when I try to use

add_action('the_loop', 'postFunction', 10);    function postFunction() { 
   
      echo "<h1>pdf link here</h1>";
}

or

add_action('pagelines_loop_after_excerpt', 'postFunction', 10);    function postFunction() { 
   
      echo "<h1>pdf link here</h1>";
}

It doesn't seem to work like 

 

add_action('the_post', 'postFunction', 10);
    function postFunction() { 
      echo "<h1>pdf link here</h1>";
}

does. 

Should I be able to use this hook? How should it work?

Second question:

If I have a blank custom section, what should I put in the 

 

function section_template() {}

to make it work like a category loop? 
The original postloop-section is so complex that I don't really understand how to use it. I know how to use loops and what to write inside if I can just get the barebone version of what this section should contain to loop posts from the category on which page it's on.

Thank you!

If I just copy paste the standard loop in a custom section the whole site wont load:
 

<?php
/*
Section: KetriLoop
Author: PageLines
Author URI: http://www.pagelines.com
Description: The Main Content area (Post Loop in WP speak). Includes content and post information.
Class Name: ketriPostLoop
Workswith: main
Failswith: 404_page
Filter: component
*/


/**
 * Main Post Loop Section
 *
 * @package PageLines DMS
 * @author PageLines
 */
class ketriPostLoop extends PageLinesSection {


   function section_template() {
if (have_posts()) : while (have_posts()) : the_post(); ?>


<div <?php post_class(); ?> id="post-<?php the_ID(); ?>">
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<?php the_content(); ?>
</div>


<?php endwhile; 
}


}

On your white screen what error is printed ? If no error is printed do you have WP_DEBUG set to true ?
