Ερωτήσεις

How to install the plugin?

Installing the plugin is a very simple process. First, you need to download the plugin from the Web Expert membership area and save it to your computer. Then, on your website, from the WordPress admin area, go to “Plugins>Add New Plugin” and select “Upload Plugin”. Finally, you select the file you saved on your computer and select “Install Now”. For more information look up the corresponding README file that comes with the plugin or consult the plugin’s documentation.

What can I do if I get an invalid license even though I entered it correctly?

First, you can try to remove the license key from the plugin settings, select save settings, and then enter it again.

In the event that the server that serves you blocks the communication to webexpert.gr, the license check cannot be carried out. You can contact your provider and ask to whitelist our IP addresses: 5.9.116.30 and 5.9.116.27.

What is the most likely reason why the XML file is not being created?

The most likely cause of the XML file not being generated is the memory limit compared to the volume of products. Please increase the memory limit, maybe the max execution time of PHP, on the side of the server that serves you.

I have a large amount of data. What can I do;

The WooCommerce Google Merchant Product Data Feed plugin is programmed to generate XML in its entirety and not in parts. This means that you need memory and power, proportional to the products. However, it is built to do proper memory management and has been tested on many providers with simple hosting packages and performs very well. To meet even the most demanding users, it can be run via WP Cron, Scheduled Tasks (Plesk), Cron Jobs (cPanel) and crontab, to minimize memory requirements.

What can I do if the XML file does not refresh automatically?

You will need to check the operation of WP_CRON.
Alternatively, if you want the XML output via a cron job rather than WP Cron, you need to call the cron.php file
e.g. php -d /home/domain/public_html/domain.gr/wp-content/plugins/webexpert-google-merchant-product-data-feed/cron.php

*Check the path of the cron.php file on your server

What can I do if I experience timeouts or a white screen when I export the XML file?

If you’re experiencing timeouts or a white screen when exporting the XML file, try reducing the value in the Max Page Size field (<100) from our plugin settings.

If you want XML to output via cron job and not WP Cron, you need to call the cron.php file:

e.g. php -d /home/domain/public_html/domain.gr/wp-content/plugins/webexpert-google-merchant-product-data-feed/cron.php

*Check the path of the cron.php file on your server

The plugin provides filters, where you can pass your own values:

we_google_merchant_product_data_feed_custom_size
we_google_merchant_product_data_feed_custom_color
we_google_merchant_product_data_feed_custom_brand
we_google_merchant_product_data_feed_custom_length
we_google_merchant_product_data_feed_custom_weight
we_google_merchant_product_data_feed_custom_width
we_google_merchant_product_data_feed_custom_height
we_google_merchant_product_data_feed_custom_description
webexpert_google_merchant_product_data_feed_custom_quantity
webexpert_google_merchant_product_data_feed_custom_offer_quantity
webexpert_google_merchant_product_data_feed_custom_gtin
webexpert_google_merchant_product_data_feed_custom_id

webexpert_google_merchant_product_data_feed_hide_certain_product_ids
webexpert_google_merchant_product_data_feed_custom_args

The hooks we offer are indicative and need modification. They should be added to the child theme’s functions.php.

To display the main language, with the use of WPML

add_filter('webexpert_google_merchant_product_data_feed_product_visibility_control','webexpert_hide_en_language_wpml',11,2);
function webexpert_hide_en_language_wpml($default,$product) {
     $langs=['el'];
     $clang = apply_filters( 'wpml_post_language_details', NULL, $product->get_id() );
     if (in_array($clang['language_code'], $langs)) {
          return true;
    }
     return false;
}

To retrieve the description or short description if either is filled

add_filter('we_google_merchant_product_data_feed_custom_description',function($description,$product){
    if (empty($product->get_short_description())) {
        return $product->get_description();
    }
    return $description;
},10,2);

To display OEM if the manufacturer doesn’t exist

add_filter('we_google_merchant_product_data_feed_custom_brand','xml_show_custom_brand',10,2);
function xml_show_custom_brand($brand,$product){
    if ($product->get_attribute('kataskevasths')) {
        return $product->get_attribute('kataskevasths');
    }else {
        return "OEM";
    }
}

To add labels in the XML

add_action('we_google_merchant_product_data_feed_additional_fields',function($product, $xml, $options){
    $parent=null;
     if ($product->is_type('variation')) {
	$parent = wc_get_product($product->get_parent_id());
    }
    $fylo=$parent ? $parent->get_attribute('pa_fylo') : $product->get_attribute('pa_fylo');
    if (!empty($fylo)) {
        $xml->writeElement('g:custom_label_0',$fylo);
    }
    $brand=$parent ? $parent->get_attribute('pa_brand') : $product->get_attribute('pa_brand');
    if (!empty($brand)) {
        $xml->writeElement('g:custom_label_1',$brand);
    }
    if ($product->is_on_sale()) {
        $xml->writeElement('g:custom_label_2','on_sale');
    }
},10,3);
