@sduar,

Here is my analysis on the update icons so far.

This update icons is only applicable on the Updates screen which can be reached using Dashboard ⟶ Updates

There are two places where we have to make the code changes.

1. On wpemaillog.com (or where EDD and EDD SL is installed)

<?php

/**
 * Filter the EDD license response data to include icons for our Downloads.
 * This has to be run from your server.
 * For testing, you may have to clear edd_api_request_{%} transient key (3 hours) on the client side.
 *
 * @param (array) $response - All response data (e.g. new_version, package, etc.)
 * @param (object) $download - EDD_SL_Download
 *
 * @return (array) $response
 *
 * @author Ren Ventura (renventura.com)
 */
function rv_eddsl_api_response_add_update_icons( $response, $download ) {

    // Retrieve icon URLs

    $response['icons'] = serialize( array(
        'svg' => '',
        '1x' => '',
        '2x' => '',
        'default' => ''
    ) );

    return $response;
}

add_filter( 'edd_sl_license_response', 'rv_eddsl_api_response_add_update_icons', 5, 2 );

The following are the action items from Step 1.

• [ ] Get the icons designed for the add-ons. For the Base plugin, since it is hosted on WordPress.org, the icons will be handled by WordPress.org API.
• [ ] Include the above snippet on wpemaillog.com by pointing the respective icons against the $response['icons'] array.

2. The add-on (Plugin)

<?php

/**
 * Filter the transient data for our plugin's icons.
 * Since icons are passed back as serialized arrays, we need to unserialize them.
 * This has to be run from within your plugin.
 *
 * @param (object) $transient - Full transient data
 * @return (object) $transient
 *
 * @author Ren Ventura (renventura.com)

function rv_update_plugins_transient_unserialize_icons( $transient ) {

    if ( is_object( $transient ) && isset( $transient->response ) && is_array( $transient->response ) ) {

        $basename = plugin_basename( __FILE__ );

        // Received a response for our plugin
        $plugin = isset( $transient->response[$basename] ) ? $transient->response[$basename] : new stdClass;

        // Are there any icons set for the plugin?
        if ( isset( $plugin->icons ) ) {
            $icons = is_string( $plugin->icons ) ? unserialize( $plugin->icons ) : $plugin->icons;
            $transient->response[$basename]->icons = $icons;
        }
    }

    return $transient;
}
add_filter( 'pre_set_site_transient_update_plugins', 'rv_update_plugins_transient_unserialize_icons', 99 );

• [ ] Include the above piece of code in the add-on plugins to let them pull the icons from wpemaillog.com site and showcase them on the Updates page.
