Products not approved as GTIN and Brand missing

Hello Steve,

Are you using a plugin for adding GTIN and Brand to your products?

In the settings page of our plugin you can add prefix wildcards used by plugins when they create custom product fields.

If you add the prefix in the “Third Party Attributes” field you can add those custom product fields so they will show up in the source fields dropdown.

Hi Auke

Thanks but it is not clear to me where to find these Third Party Attributes. The GTIN field is generated using code in the functions.php file. The brands are generated by the Brands for Woocommerce by BeRocket plugin.

The code for the GTIN is:-

// save simple product GTIN
add_action(‘woocommerce_process_product_meta’,’woocom_simple_product_gtin_save’);
function woocom_simple_product_gtin_save($post_id){
$gtin_post = $_POST[‘_gtin’];
// save the gtin
if(isset($gtin_post)){
update_post_meta($post_id,’_gtin’, esc_attr($gtin_post));
}
// remove if GTIN meta is empty
$gtin_data = get_post_meta($post_id,’_gtin’, true);
if (empty($gtin_data)){
delete_post_meta($post_id,’_gtin’, ”);
}
}

Is the attribute you mention for the GTIN _gtin% ?

I am not sure where to find the attibute for the Brands.

Regards

Hi Auke

I have tried adding _gtin% and/or _gtin to the 3rd party attributes in your plugin. Then in the drop down list I now get a blank line in approx third place.

I still can’t find what to use for the brands plugin.

Hello Steve,

Can you share the complete custom post field code?
I think it is not complete.

We have our own little helper plugin you can look at here:

Hi Yes sorry I only put up part of the code. As I thought this woudl be enough. I’ve checked the data base files and they show that _gtin is the field title for the EAN codes. The database also shows the field for the brands as _berocket_brands but when I enter this in your variables it does not show.

Here is the full GTIN code from the functions.php file:-

/**
* Adding Custom GTIN Meta Field
* Save meta data to DB
*/
// add GTIN input field
add_action(‘woocommerce_product_options_inventory_product_data’,’woocom_simple_product_gtin_field’, 10, 1 );
function woocom_simple_product_gtin_field(){
global $woocommerce, $post;
$product = new WC_Product(get_the_ID());
echo ‘<div id=”gtin_attr” class=”options_group”>’;
//add GTIN field for simple product
woocommerce_wp_text_input(
array(
‘id’ => ‘_gtin’,
‘label’ => ‘GTIN’,
‘desc_tip’ => ‘true’,
‘description’ => ‘Enter the Global Trade Item Number (UPC,EAN,ISBN)’)
);
echo ‘</div>’;
}
// save simple product GTIN
add_action(‘woocommerce_process_product_meta’,’woocom_simple_product_gtin_save’);
function woocom_simple_product_gtin_save($post_id){
$gtin_post = $_POST[‘_gtin’];
// save the gtin
if(isset($gtin_post)){
update_post_meta($post_id,’_gtin’, esc_attr($gtin_post));
}
// remove if GTIN meta is empty
$gtin_data = get_post_meta($post_id,’_gtin’, true);
if (empty($gtin_data)){
delete_post_meta($post_id,’_gtin’, ”);
}
}

The meta key _gtin is being stored in the postsmeta table, as is the meta key _yoast_wpseo_primary_berocket_brand, if that is any help? ??

I’ve also done a search in the database for the terms gtin and brands and the main entries for both appear to be in the postsmeta table.

I’m probably just getting myself lost now!!

Cheers

Steve

Hello @stevehale,

Could you try to add %_gtin% in the “Third Party Attributes” field on the Settings page?

I’ve seen that sometimes you need to add a % wildcard to both the end as the start of the string.

Hi Michel

Yes that worked but it also added a blank line at thrid position again, whereas gtin came in correct alphabetical place.

I did download your plugin but the only drage with your plugin is that it has no ability for brand sorting, brand images and so on…..

Any ideas about the product brands from the BRocket plugin?

Cheers

Steve B

I will remove the blanks from this list in the next update.

As for the BRocket plugin, I don’t know. I could not find that plugin in the available plugins. Usually you should look for the

update_post_meta( $post_id, '_gtin', esc_attr( $gtin_post ) );

line in which the second item is the name under which the data is stored in the database. That line should be (partially) enclosed in two % characters to get it in the list.

As you will understand, there are hundreds of different plugins and we can’t support them all. That’s why the third party attributes has been added so users can implement this support themselves.

Let me know if you could find the required string.

Best regards,
Michel

Hi @stevehale

Any luck on finding the correct string?

Best regards,
Michel

Hi @stevehale,
You have not heard back from you so i assume you have found the correct string.

I’ll mark this ticket as resolved, but if there are any issues don’t hesitate to reopen it again.
