You can insert custom content at the bottom of the report, before the Closing. Edit lines 6 — 8 to add your own custom content:
/** * Insert custom content before the report Closing. */ function my_zp_report_before_closing( $closing ) { $out = '<h3 class="zp-report-section-title">Extra Section At Bottom of Report</h3>'; $out .= '<p>Custom content at the end of the report, before the closing.</p>'; return $out . $closing; } add_filter( 'zp_report_closing', 'my_zp_report_before_closing' );
