Hi there
Sorry in advance I’m quite new to this and although I have a rough understanding of ACF I’m struggling with this issue despite reading a lot of the threads and documentation.
I’m looking to introduce a gallery of 4 images on numerous pages whose alt text I would like to set in ACF. I already use ACF for simple text population with shortcodes inside WPBakery Theme. However, Im assuming this may need to be coded in manually, would anyone know how I would achieve this via WordPress?
Any help would be greatly appreciated, although I’m now stuck in the house for the foreseeable future ive read everything I can and don’t seem to be getting anywhere.
Thanks in advance
Paul
If you’re using shortcodes to add ACF fields to pages then your going to need to build a custom shortcode which will require adding code to the theme’s functions.php file or possibly some other file depending on your theme.
You can start here https://codex.wordpress.org/Shortcode_API
There are some tutorials and guides available like this https://www.wpbeginner.com/wp-tutorials/how-to-add-a-shortcode-in-wordpress/ and this https://www.smashingmagazine.com/2012/05/wordpress-shortcodes-complete-guide/
This is the basic shortcode code in ACF for a reference.
/*
* acf_shortcode()
*
* This function is used to add basic shortcode support for the ACF plugin
* eg. [acf field="heading" post_id="123" format_value="1"]
*
* @type function
* @since 1.1.1
* @date 29/01/13
*
* @param $field (string) the field name or key
* @param $post_id (mixed) the post_id of which the value is saved against
* @param $format_value (boolean) whether or not to format the field value
* @return (string)
*/
function acf_shortcode( $atts ) {
// extract attributs
extract( shortcode_atts( array(
'field' => '',
'post_id' => false,
'format_value' => true
), $atts ) );
// get value and return it
$value = get_field( $field, $post_id, $format_value );
// array
if( is_array($value) ) {
$value = @implode( ', ', $value );
}
// return
return $value;
}
add_shortcode('acf', 'acf_shortcode');
Hi John,
Thanks for your response. I do use one or two shortcodes already within our theme and know how to edit the functions file however this is where knowledge ends and unsure on how to create a gallery referencing the alt tags using a shortcode.
Kindest regards
Paul
Not sure what you’re looking for. You would get values in the shortcode the same way you’d get them in when adding code to a theme like is discussed on the gallery field page https://www.advancedcustomfields.com/resources/gallery/
The main difference is that you need to supply the post id of the post as is done by the built in ACF shortcode.
