NDV Product Image Upload for WooCommerce

// Register an additional admin tab.
// $tabs is a map of slug => array( label, icon, callback ).
apply_filters( 'cpiu_admin_tabs', $tabs );

// Extend or adjust global settings as they are saved.
apply_filters( 'cpiu_save_global_settings', $sanitized, $raw );

// Attach your own keys to a per-product configuration during sanitisation.
apply_filters( 'cpiu_sanitize_configuration', $sanitized, $config );

// Override the resolved configuration for a product on the front end.
apply_filters( 'cpiu_product_config', $config, $product_id );

// Return false to suppress the default front-end preview.
apply_filters( 'cpiu_show_image_preview', true, $product_id, $config );

// Extend the upload allowlists.
apply_filters( 'cpiu_allowed_mime_types', $default_mime_types );
apply_filters( 'cpiu_allowed_extensions', $default_extensions );

// Adjust how the client IP is resolved (proxies, CDNs).
apply_filters( 'cpiu_client_ip', $ip );

Example — add your own admin tab:

add_filter( 'cpiu_admin_tabs', function ( $tabs ) {
    $tabs['my-reports'] = array(
        'label'    => __( 'Reports', 'my-plugin' ),
        'icon'     => 'dashicons-chart-bar',
        'callback' => 'my_plugin_render_reports_tab', // receives array $context
    );
    return $tabs;
} );

Example — store your own key alongside each product configuration:

add_filter( 'cpiu_sanitize_configuration', function ( $sanitized, $raw ) {
    $sanitized['my_key'] = isset( $raw['my_key'] )
        ? sanitize_text_field( $raw['my_key'] )
        : '';
    return $sanitized;
}, 10, 2 );

⚠ Security note: cpiu_allowed_mime_types and cpiu_allowed_extensions control what the upload validator will accept. Widening them — adding SVG, for instance — bypasses a deliberate restriction and is a security decision, not a convenience tweak.
