Reference Post (I was even downvoted here.)

My short code was not working on my custom theme, but the same short code, when used in twenty fifteen, was working.

I researched over google and found that it was something related to not using the_content correctly.

  1. https://kb.yoast.com/kb/shortcodes-not-rendering/
  2. https://wordpress.org/support/topic/shortcodes-not-working-custom-theme/

I applied the solution suggested in the Yoast →

that means I changed from

<?php the_content(); ?>


<?php echo apply_filters( 'the_content', $post->post_content ); ?>

But still, the shortcodes are not working.

what is the working fix?

I have this code in single.php →

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
                            <?php $post_id = get_the_ID(); ?>
                            <?php get_template_part('content',get_post_format()); ?>
                        <?php endwhile; ?>
                        <?php endif; ?>

and in content.php →

<?php the_content(); ?>

enter image description here


function simplisto_the_image($atts) {
    $atts = shortcode_atts( array(
        'to' => 'https://pics.wikifeet.com/Melania-Trump-Feet-720891.jpg'
    ), $atts);
    $output = '<div class="lazyimg">';
            $output .= '<img class="lazyimg-popup" src="'.$atts['to'].'" alt="The First Caption" width="100%" height="auto">';
        $output .= '<i class="fa fa-expand" aria-hidden="true"></i>';
    $output .= '</div>';
    return $output;

function register_shortcodes(){
   add_shortcode('simage', 'simplisto_the_image');

add_action( 'init', 'register_shortcodes');
  • Try echo do_shortcode( get_the_content() ); – user125500 Aug 8 '17 at 18:47

    You said you changed the_content() to apply_filters, but then you say content.php has the_content().... it should have apply_filters no? – gdaniel Aug 8 '17 at 19:12

    what is the exact full code of your shortcode function? does the same problem exist when you use one of the generic shortcodes like [gallery]? – Michael Aug 8 '17 at 21:58

    ps: are you using any postformat for the post? – Michael Aug 8 '17 at 22:03

    Can you try to replace function register_shortcodes()...to the end with just add_shortcode('simage', 'simplisto_the_image'); – rudtek Aug 8 '17 at 22:25

Excuse brief answer (writing on train in iPhone) but I would try changing get_template_part() to its non-WordPress include() equivalent as, from memory, variables declared outside your content.php won't be available otherwise.

  • @Jack Johansson Any clue? – The WP Intermediate Aug 8 '17 at 20:48
  • even if I am trying this in content.php → <?php echo do_shortcode("[simage]"); ?> still it is not generating the DESIRED OUTPUT. there is something else that is fundamentally missing in the theme. I have no clue what is that? – The WP Intermediate Aug 8 '17 at 21:23
  • Please guide me one step further sir. Please help. – The WP Intermediate Aug 9 '17 at 14:17
  • I have accepted the answer. – The WP Intermediate Oct 5 '17 at 2:31
