It is possible to add links (URLs) to submission PDF exports using the WS Form wsf_submit_export_csv_header and wsf_submit_export_csv_row filter hooks.
Sample code for doing so can be found below:
// Add a callback function for the wsf_submit_export_csv_row filter hook add_filter( 'wsf_submit_export_csv_header', 'wsf_submit_export_csv_header_function', 10, 2 ); // Callback function for the wsf_submit_export_csv_header filter hook function wsf_submit_export_csv_header_function( $csv_header, $form_id ) { // Add PDF URL to CSV export header $csv_header['pdf_url'] = __('PDF URL', 'ws-form'); // Return key value pairs array for CSV header return $csv_header; } // Add a callback function for the wsf_submit_export_csv_row filter hook add_filter( 'wsf_submit_export_csv_row', 'wsf_submit_export_csv_row_function', 10, 3 ); // Callback function for the wsf_submit_export_csv_row filter hook function wsf_submit_export_csv_row_function( $csv_row, $form_id, $submit ) { // Create instance of the PDF action class $ws_form_action_pdf = new WS_Form_Action_PDF(); // Get PDF URL $pdf_url = $ws_form_action_pdf->get_pdf_url( $submit->hash, // Submission hash $form_id, // Form ID true // Download (true = Yes, false = No) ); // Add PDF URL to CSV row $csv_row['pdf_url'] = $pdf_url; // Return key value pairs array for CSV row return $csv_row; }
