Programmatically add featured image with ALT text in Wordpress? -


there examples of how add post featured image programmatically in wordpress, need add post featured image , alt text too. how can that?

thank you.

if @ source wp_get_attachment_image function, can see how alt text being fetched:

'alt'   => trim(strip_tags( get_post_meta($attachment_id, '_wp_attachment_image_alt', true) ))

from there easy enough figure out how update alt text.

update_post_meta($attachment_id, '_wp_attachment_image_alt', 'my alt text');
