Force returning to the main page when browser reload button pressed on results

Solution from C. York:

/**REH clear submit button, so that reload doesn’t resubmit selection and just goes back to previous screen**/

$ret .= ‘ <script> ‘;

$ret .= ‘ if ( window.history.replaceState ) {

window.history.replaceState( null, null, window.location.href );

} ‘;

$ret .= ‘</script> ‘;

/**REH End clear submit button**/

I put it at the end of the first part of the “if ( count($rows) ) {” section before the else
