Problem:
If you're experiencing performance issues when copying Advanced Custom Fields (ACF) to translations with WPML, such as slow operations or timeouts, this might be due to inefficiencies in the code handling the copy process.
Solution:
We recommend modifying the
SitePress::copy_custom_fields
and
WPML_Copy_Once_Custom_Field::copy
methods to improve performance. Here are the steps to follow:
1. Locate the
SitePress::copy_custom_fields
method in
wp-content/plugins/sitepress-multilingual-cms/sitepress.class.php
and replace it with the provided code.
2. Locate the
WPML_Copy_Once_Custom_Field::copy
method in
wp-content/plugins/sitepress-multilingual-cms/classes/custom-field-translation/class-wpml-copy-once-custom-field.php
and replace it with the provided code.
These changes should optimize the process by reducing the number of instances where the entire post meta is fetched and looped through, thus improving the performance when copying ACF fields to translations.
