Code making content disappear

Also, the related item is not showing.

I will look into it.

Can you tell me more? Is there an error in error_log of Apache?
Anything in the html when you view the source?
Also, what theme do you use?

In View Source, nothing shows below where the code should be. You can view the source here. the code is placed just under the closing </article> tag. I have also tried placing it in other areas. Anywhere I place it, everything below the code disappears. Am I supposed to wrap the code with anything else?

Also, assuming I can get this up and running, it is possible to have 2 instances on the same post/page? I would like one section to have related ships and another for optional extended vacations. I know I would have to manually select the related content for each, I would just like to separate the related content for a cleaner look.

thanks for the prompt response. The true sign of a great developer.

Thank you. You didn’t answer all my questions though.
– Is there anything in error_log of Apache?
Also,
– What version of PHP do you use?

I’m not sure what the cause is, but does it work when you place <?php global $related; ?> in front of the other line?

I don’t see anything strange in my test environment. That is Debian Linux with PHP 5.5. I will test on RH5 with PHP 5.4 again.

And oh, you can have as many lists of related posts as you want I reckon. I haven’t tried that, but it should just work.
The PHP instance is just an object. The show method returns the list, depending on the post ID that’s given as an argument.

Sorry, nothing related in the error log. PHP version is 5.4.22

Just added <?php global $related; ?> and it worked. I can now see the title of the related article and the rest of the content!

Resolved. Excellent Support!

Now if I only knew why it happns with you, but not on my install :).
I will add it to the documentation at least. I will also test on another server as well.

Not sure why it happens on mine. I am using a template with a specific post type, so it may be playing tricks on it. thanks for the quick responses.

Also, I have worked the multiple instances of the related plugin. My WordPress and PHP skills are on the amateur side, so I probably took the long way to get a solution. Here’s what I did…

I unzipped your plugin and simply searched and replaced all variations of $related, $rel and $r (i think that was everything) with a new variation such as $ship, $shp and $s. I also renamed the files that contained “related” in the name. I zipped them up and installed through WordPress. I created 2 extra versions, so I have 3 running on my site.

I inserted the appropriate code containing the new $ship, $shp and $s on the template and it worked.

Ah, an interesting use of the plugin.
If all those posts have no way to distinguish them, then your approach might be good.
But I can imagine that the different posts have some way to distinguish them. Like a different post_type or category. Then you could have 1 plugin, and have 3 more extensive loops where you do a check on post_type or category, and only display those posts at that place.

A loop could look like:

<?php
     global $related;
    $rel = $related->show(get_the_ID(), true);

    // Display the title of each related post
    foreach ($rel as $r) :
        if ($r->post_type == 'post') {
               echo $r->post_title . '<br />';
        }
    endforeach;
?>
