Hello,
I am attempting to use some simple shortcodes for columns inside a textarea. I tried using all three options for line breaks and my shortcodes will still not output. They work fine with the Wysiwyg field type. Do I need to do anything specific to make them work?
I am using ACF Pro by the way.
Text areas are not designed for shortcodes, but you could try something like:
function text_area_shortcode($value, $post_id, $field) {
if (is_admin()) {
// don't do this in the admin
// could have unintended side effects
return;
}
do_shortcode($value);
return $value;
}
add_filter('acf/load_value/type=textarea', 'text_area_shortcode', 10, 3);
You could limit this to only a specific field by changing the hook to ‘acf/load_value/name={$field_name}’ or you could check $field inside the function for specific field names, or even add multiple add_filter() calls for different fields. Depends on how many text areas you want to filter and use shortcodes in.

Hi guys
Nice one @Hube2. You can also use the format_value filter to avoid the is_admin() conditional:

This is really nice, to allow editors to put emphasis and links in some textareas.
Is there a way you could limit *which* shortcodes are available?
Not really… an least not easily, do_shortcode is indiscriminate. If it’s a registered shortcode WP will run it.
It could be done with some work. You’d need to first build your own shortcode function/filter and use this instead of the WP hook. Look at the core function do_shortcode(). You’d pretty much need to do everything that function does, and possibly some of what the called functions do, yourself and build a “White List” to check shortcodes against to see if they should be run or not.
@hube2’s code has a bug. Corrected code
function text_area_shortcode($value, $post_id, $field) {
if (is_admin()) {
// don't do this in the admin
// could have unintended side effects
return;
}
return do_shortcode($value);
}
add_filter('acf/load_value/type=textarea', 'text_area_shortcode', 10, 3);
Revision:
function text_area_shortcode($value, $post_id, $field) {
if (is_admin()) {
// don't do this in the admin
// could have unintended side effects
// revision: return $value because we don't want to miss on the textarea content
return $value;
}
return do_shortcode($value);
}
add_filter('acf/load_value/type=textarea', 'text_area_shortcode', 10, 3);
