Add a <!--more--> tag to a custom post type

Question

I'm building a portfolio site for a friend and he's got three seperate photo packages and may want to add more in the future, so I've created a custom post type called Packages so that he can add as many as he likes and they'd all appear on one page. I've created a single-packages.php template so that each package would link to a sinple.php page to show the full content, but when I add the 'more' tag within the editor it doesn't split the content and the packages page spews out everything rather than just showing the content before the 'more' tag.

Any help on this much appreciated.

note - I'm not a PHP expert and so won't understand complex coding suggestions

Answer 1

In some situations, the $more global needs to be set to 0 before calling the_content() in order to show the read more link:

 global $more;
 $more = 0;
 the_content( '<span>Read More...</span>' );

Answer 2

I've had the same problem and found this to be the best solution:

<?php
   $content = get_the_content(); 
   $dot = "."; 
   $position = stripos ($content, $dot); 

   if($position) { 
        $offset = $position + 1; 
        $position2 = stripos ($content, $dot, $offset); 
        $first_one = substr($content, 0, $position);
        $first_two = substr($content, 0, $position2); 

        if($position2 > 120) {
           echo $first_one . '.';
        }

        else {
            echo $first_two . '.';
         }
   }

         else {  

         }

?>

The code above displays two first sentences (the post excerpt) and if they are longer than 120 symbols - it will display only the first one.

If there are no dots in the content it does nothing.

Now just attach Read more link after your excerpt:

<a class="read-more" href="<?php the_permalink(); ?>">Read more...</a> 

And everything is fine.

I'm not sure why "more tag" doesn't work for some custom post types, but I spent a lot of time figuring it out and after all ended with this silly function.

I'm not a PHP programmer neither and I know this solution is pretty long and complex, but that's the only thing that worked for me and I was in the same spot.

The function isn't perfect and doesn't recognize dots after words like "etc." or "e.g.", it will treat every dot as sentence ending.
