*--------------- | |
* Usage Example: | |
*--------------- | |
* | |
* To change all custom product meta attributes "color" to "pa_color" products taxonomy (where pa_ is a WooCommerce auto-added prefix), we can run: | |
* | |
* https://example.com/?woopam_mode=run&woopam_from_attribute_meta=color&woopam_to_attribute_tax=pa_color&woopam_keep_attribute_meta=1&woopam_posts_per_page=100&woopam_paged=0&woopam_post_type=product&woopam_post_status=any | |
* | |
* REMEMBER: Create the product taxonomy beforehand here (without pa_ prefixing it yourself): | |
* | |
* https://example.com/wp-admin/edit.php?post_type=product&page=product_attributes | |

Error message says - ** Invalid taxonomy.**
Plugin doesn't transfer attributes written in languages other than English, is it possible to fix it somehow?
Hi all, thanks for your comments, I forgot about the script for a long time :-)
I will look into the reported problems above.
I've updated to version 1.0.0 and hopefully fixing the issues mentioned here above.
Notice the new GET parameters names
Hello @birgire thanks a lot for this snipped. I'm also trying to convert a custom product attribute in a global attribute (for translation). Unfortunately I get the error message "invalid_taxonomy" even though my global taxonomy does exist. I'm using the latest WooCommerce version.
Hello @klemensh
I wonder what query string you use and what's the name/slug of the attribute taxonomy?
This plugin almost seem like answer to my problem but I have same problem than thomastruett earlier. For some reason it just adds global variables to product but does not remove custom one or replace attributes in the stock page. It shows custom attribute with value and global attribute with "any size".
Am I doing something wrong?
Hi, just to help anyone that comes to this page sharing the same problem. Custom attribute to global (taxonomy), variations, etc...
How we solved it easily:
- We created the same name of the Custom Attribute as a Global Attribute (Brand => Brand). No need to add terms, just attribute Name.
- Downloaded (Export) all the products as CSV file on the All Products table page.
- On the CSV file (opened on Excel) make sure to set Attribute n global (n is the number of attribute, 1, 2, etc...) to 1 (when it's custom it will show 0). Do this on all rows that have the attribute you are converting.
- To make sure Variations also saved and that attribute can be used make sure that Attribute n visible is also set to 1 on all rows.
- Save the file.
- Next go back to your All Products page and click on Import.
- Choose the file and check the box that says "Existing products that match by ID or SKU will be updated. Products that do not exist will be skipped.".
- Next click on Run the importer button.
This will convert all the custom attributes with their terms into global, and also keep all the variations. No need for any coding or hard work.
For the steps 3 and 4 you can use formula like this one =IF(AN2="Flavors","1","") for the first line and copy paste it to all rows to do it automatically for a specific attribute if needed.
Hopefully this will help you.
To also preserv the variations, I added this code after the row "update_post_meta( $post_id, $meta_key, $meta );
":
$args = array(
'post_type' => 'product_variation',
'post_status' => 'any',
'post_parent' => $post_id,
'fields' => 'ids',
'posts_per_page' => -1
);
$variations = get_children( $args );
if ( is_array( $variations ) && count( $variations ) > 0 ) {
foreach ( $variations as $variation_id ) {
$term = get_post_meta( $variation_id, 'attribute_' . strtolower( $from_attribute_meta ), true );
delete_post_meta( $variation_id, 'attribute_' . strtolower( $from_attribute_meta ) );
update_post_meta( $variation_id, 'attribute_' . $to_attribute_tax, strtolower( $term ) );
}
$default_attributes = get_post_meta( $post_id, '_default_attributes', true );
if ( is_array( $default_attributes ) ) {
foreach ( $default_attributes as $key => $term) {
if ( $key == strtolower( $from_attribute_meta ) ) {
unset( $default_attributes[$key] );
$default_attributes[$to_attribute_tax] = strtolower( $term );
}
}
update_post_meta( $post_id, '_default_attributes', $default_attributes );
}
}
Thanks for your feedback @smoovo and @realweb11
Hey @birgire thank you so much for this code!
I've made some adjustments that refine variations handling, since the attribute name get slugified and my terms had some special chars in them I had problems with both the import method and the @realweb11 code above.
Line 105
/* Get only products that shares the target attribute */
'meta_query' => [
[
'key' => $meta_key,
'compare' => 'LIKE',
'value' => sprintf('"%s"', $from_attribute_meta)
]
],
Line 129
/* Selected target attribute by slug to avoid issues with spaces and special characters */
if ( $from_attribute_meta === $key ) {
Line 172
/* Added code from @realweb11 with the correction of the slug for the new term (used sanitize_title instead of strtolower) */
$args = array(
'post_type' => 'product_variation',
'post_status' => 'any',
'post_parent' => $post_id,
'fields' => 'ids',
'posts_per_page' => -1
);
$variations = get_children( $args );
if ( is_array( $variations ) && count( $variations ) > 0 ) {
foreach ( $variations as $variation_id ) {
$term = get_post_meta( $variation_id, 'attribute_' . strtolower( $from_attribute_meta ), true );
delete_post_meta( $variation_id, 'attribute_' . strtolower( $from_attribute_meta ) );
update_post_meta( $variation_id, 'attribute_' . $to_attribute_tax, sanitize_title( $term ) );
}
$default_attributes = get_post_meta( $post_id, '_default_attributes', true );
if ( is_array( $default_attributes ) ) {
foreach ( $default_attributes as $key => $term) {
if ( $key == strtolower( $from_attribute_meta ) ) {
unset( $default_attributes[$key] );
$default_attributes[$to_attribute_tax] = sanitize_title( $term );
}
}
update_post_meta( $post_id, '_default_attributes', $default_attributes );
}
}
Note: With these modifications, it's crucial that the parameter woopam_from_attribute_meta
is the slug of the starting attribute.
Thank you again for your gist!
Awesome, thank you for sharing @emmelemme
gives the error There was an error somewhere and the terms couldn't be set for post_id
