Let me start off by saying that I usually make alot of research before asking publicly for help - due to likelyhood of information already being on the web - altho I've done several days of reseach etc I'm still in agony...

I'm using Wordpress with Advanced Custom Fields plugin - I've been able to make it show the image on my front page using a simple HTML code

<img src="[acf field='image' post_id=''. $post_id .'']" />

Where I created a custom field called 'image' . Now I want to create a shortcode to display this link if possible? I've gone through alot of possiblities such as;

Tried this too;

function my_shortcode() {
    $output = '';
    $output.= '<img src="[acf field='image' post_id=''. $post_id .'']" />';
    return $output;

Didnt take... then I went for the last one I could find on the web;

    function my_shortcode() {
    ?> <HTML> <img src="[acf field='image' post_id=''. $post_id .'']" /> <?php
    return ob_get_clean();

Which ended into something like this on my website - outcome

I'm really out of my depth here guys... I'd be really glad if anyone would be willing to help me out a little!

Thanks in advance!

You have to use do_shortcode() to execute shortcodes in your string

Full code should be like that

function my_shortcode( $atts ) {
    $atts = shortcode_atts( array(
        'post_id' => '', // Default value.
    ), $atts );

    $output = '[acf field="image" post_id="' . $atts['post_id'] . '"]';
    $output = do_shortcode( $output );
    $output = '<img src="' . $output . '" />';
    return $output;

add_shortcode('my_link', 'my_shortcode');


[my_link post_id="xxx"]

where xxx is id of the requered post.

  • Hey there! Thanks for a really fast answer! Did you mean to change the $output in here prntscr.com/i2kmu7 ? Thanks a lot again

  • Exactly. do_shortcode() executes shortcodes in your string. Commented Jan 19, 2018 at 9:41
  • I have extended the answer Commented Jan 19, 2018 at 9:43
  • And I hope you understand that $post_id must be send to my_shortcode function Commented Jan 19, 2018 at 9:45
  • Hey, thanks for the edits and for the effort - prntscr.com/i2kto6 leads to prntscr.com/i2ku0y (empty site) - should I look into something different rather than the code itself ? Maybe some settings I should modify to enable the function.php file?

enter image description here

function my_shortcode(){
return '<img src="[acf field='image' post_id=''. $post_id .'']" />';
  • All looks good.

  • prntscr.com/i2ks7y ends up into prntscr.com/i2ksk1 I'm not really sure - should I edit some other document to enable the function.php - if I comment the whole php code - the site's working again

  • For the last time: Please stop posting plain code snippets; edit your answer, and add an explanation: why could that solve the problem?
