What can I do in order to add an ACF textarea
into a Genesis child theme template.
I tried a lot but did not find any way.
Thank you.
First you have to figure out where you want to put the field. You can either use one of the genesis hooks (see here) or perhaps your modifying a theme field directly in which case you can just paste the code whereever you want.
For example if you're using a hook and you want to put it in your header, you could do something like:
add_action('genesis_header', 'add_content_to_header');
function add_content_to_header() {
echo get_field('my_textarea_field');';
}
Or do put it directly into a child theme template file, just put this whereever you want:
the_field('my_textarea_field');';
