The user needs to update the 'book-url' custom field value for all posts of the 'book' post type without having to edit each post individually.
Solution:
You can use a code like this:
[php]function update_book_urls($post_type, $url) {
// Get all posts of the 'book' post type
$args = array(
'post_type' => $post_type,
'posts_per_page' => -1,
);
$book_posts = get_posts( $args );
// Loop through each post and update the 'book-url' custom field
foreach ( $book_posts as $post ) {
update_post_meta( $post->ID, 'wpcf-saas-deal-link', $url );
}
}
update_book_urls('saas', 'https://book.com');
[/php]
I have a custom field group where I have bunch of custom fields. If I change the slugs of the custom fields, will it create any issue, like data loss of the custom fields?
Solution:
Yes, it can produce some issues - which can be resolved, but perhaps it'll be a costly manual labor. For instance:
- we have an image field on a content template
- we go to the Custom Field group of this image field
- change its current slug ('image') to anything different -> 'image-test', for example
After this change, we'll check that the image displaying on the content template just disappears. Because it still thinks that the slug is 'image' - therefore, we would need to select the image field again, in order to make the system recognizes the new slug. Please check the screenshot: https://snipboard.io/rYb0Pl.jpg
This will happen to any field that you change its slug. If you have several fields, you'll need to re-select all of them and maybe it would be a extensive manual work.
