This thread is resolved. Here is a description of the problem and solution.
Problem:
You are experiencing a significant slowdown when saving content in French on your WordPress site using WPML with French as the secondary language and ACFML for managing custom fields translations. The issue disappears when the ACF Multilingual plugin is deactivated.
Solution:
We recommend modifying specific methods in the WPML plugin files to potentially resolve the performance issue. Here are the steps:
1. Navigate to
\wp-content\plugins\sitepress-multilingual-cms\sitepress.class.php
and modify the
copy_custom_fields
method as follows:
function copy_custom_fields( $post_id_from, $post_id_to ) {<br /> $custom_fields_to_copy = $this->get_custom_fields_translation_settings( WPML_COPY_CUSTOM_FIELD );<br /> $custom_fields_from = get_post_meta( $post_id_from );<br /> $custom_fields_to = get_post_meta( $post_id_to );<br /><br /> foreach ( $custom_fields_to_copy as $meta_key ) {<br /> if ( array_key_exists( $meta_key, $custom_fields_from ) ) {<br /> $meta_from = isset( $custom_fields_from[ $meta_key ] ) ? $custom_fields_from[ $meta_key ] : [];<br /> $meta_to = isset( $custom_fields_to[ $meta_key ] ) ? $custom_fields_to[ $meta_key ] : [];<br /><br /> if ( $meta_from || $meta_to ) {<br /> $this->sync_custom_field( $post_id_from, $post_id_to, $meta_key );<br /> }<br /> }<br /> }<br /><br /> $sync_deleted_fields = false;<br /> if ( apply_filters( 'wpml_sync_deleted_custom_fields', $sync_deleted_fields ) && $custom_fields_from && $custom_fields_to ) {<br /> $if_deleted_in_source_and_still_in_target = Logic::allPass([<br /> Obj::prop( Fns::__, $custom_fields_to ),<br /> pipe( Obj::prop( Fns::__, $custom_fields_from ), Logic::not() ),<br /> ]);<br /><br /> wpml_collect( $this->get_custom_fields_translation_settings( WPML_TRANSLATE_CUSTOM_FIELD ) )<br /> ->filter( $if_deleted_in_source_and_still_in_target )<br /> ->map(function ( $meta_key ) use ( $post_id_from, $post_id_to ) {<br /> $this->sync_custom_field( $post_id_from, $post_id_to, $meta_key );<br /> });<br /> }<br />}2. Navigate to
\wp-content\plugins\sitepress-multilingual-cms\classes\custom-field-translation\class-wpml-copy-once-custom-field.php
and modify the
copy
method as follows:
public function copy( $post_id ) {<br /> $custom_fields_to_copy = $this->sitepress->get_custom_fields_translation_settings( WPML_COPY_ONCE_CUSTOM_FIELD );<br /> if ( empty( $custom_fields_to_copy ) ) {<br /> return;<br /> }<br /><br /> $source_element_id = $this->wpml_post_translation->get_original_element( $post_id );<br /> $custom_fields = get_post_meta( $post_id );<br /><br /> foreach ( $custom_fields_to_copy as $meta_key ) {<br /> if ( array_key_exists( $meta_key, $custom_fields ) ) {<br /> $values = isset( $custom_fields[ $meta_key ] )<br /> && ! empty( $custom_fields[ $meta_key ] )<br /> ? [ $custom_fields[ $meta_key ] ]<br /> : [];<br /><br /> $values = apply_filters(<br /> 'wpml_custom_field_values',<br /> $values,<br /> [<br /> 'post_id' => $post_id,<br /> 'meta_key' => $meta_key,<br /> 'custom_fields_translation' => WPML_COPY_ONCE_CUSTOM_FIELD,<br /> ]<br /> );<br /><br /> if ( empty( $values ) && $source_element_id ) {<br /> $this->sitepress->sync_custom_field( $source_element_id, $post_id, $meta_key );<br /> }<br /> }<br /> }<br />}If this solution does not resolve your issue or seems irrelevant due to updates or different circumstances, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins.
