Hi!
I want to get the featured image of post and save it as a image field. I saw old comments taking about how do it upside down “field to feature”, but no “feature to field”.Anyone know how do it?
This is the code I saw:
<?php
function acf_set_featured_image( $value, $post_id, $field ){
if($value != ''){
//Add the value which is the image ID to the _thumbnail_id meta data for the current post
add_post_meta($post_id, '_thumbnail_id', $value);
}
return $value;
}
// acf/update_value/name={$field_name} - filter for a specific field based on it's name
add_filter('acf/update_value/name=cursusfoto', 'acf_set_featured_image', 10, 3);
?>
add_action('acf/save_post', 'move_image_to_post_thumbnail');
function move_image_to_post_thumbnail($post_id) {
if (get_field('your-image-field-name', $post_id, false)) {
// get unformatted value
// we did it above too, no point formatting the value for this
$image_id = get_field('your-image-field-name', $post_id, false);
update_post_meta($post_id, '_thumbnail_id', $image_id);
}
}
Would it be possible to use the same code with some modifications to get the value of a field and use it as the meta-key _yoast_wpseo_focuskw? Something like this:
add_action('acf/save_post', 'automatic_keywords');
function automatic_yoast_keywords($post_id) {
if (get_field('_yoast_wpseo_focuskw', $post_id, false)) {
// get unformatted value
// we did it above too, no point formatting the value for this
$image_id = get_field('_yoast_wpseo_focuskw', $post_id, false);
update_post_meta($post_id, 'name', $meta);
}
}
It works inverting the terms 🙂
add_action('acf/save_post', 'move_image_to_post_thumbnail');
function move_image_to_post_thumbnail($post_id) {
if (get_field('_thumbnail_id', $post_id, false)) {
// get unformatted value
// we did it above too, no point formatting the value for this
$image_id = get_field('_thumbnail_id', $post_id, false);
update_post_meta($post_id, 'image', $image_id);
}
}
