Question

i have developed a form to update several fields in a table but upon submission it returns an clear page. here is the code that i am using for submission.

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form")) {

    $doa_bits = explode('/', $_POST['doa']);

  $updateSQL = sprintf("UPDATE tbl_personalinjury SET role=%s, driverNo=%s, clientName=%s, address=%s, residedYrs=%s, cntctSolicitor=%s, telephoneHome=%s, telephoneMobile=%s, time=%s, time2=%s, dobDay=%s, dobMonth=%s, dobYear=%s, maritalStatus=%s, job=%s, niNo=%s, doaDay=%s, doaMonth=%s, doaYear=%s, time3=%s, time4=%s, weather=%s, location=%s, policeDetail=%s, accidentDetail=%s, blame=%s, witnessDetail=%s, dName=%s, dAdd=%s, dvMake=%s, dvModel=%s, dReg=%s, dInsurance=%s, tName=%s, tAdd=%s, tvMake=%s, tvModel=%s, tReg=%s, tInsurance=%s, seatbelt=%s, injuries=%s, injuries2=%s, recover=%s, timeoff=%s, loss=%s, expenses=%s, sports=%s, hospital=%s, gpName=%s, gpAddress=%s WHERE id=$client_id",

}

mysql_select_db($database_speedycms, $speedycms);
$query_accident = "SELECT * FROM tbl_personalinjury WHERE id=$client_id";
$accident = mysql_query($query_accident, $speedycms) or die(mysql_error());
$row_accident = mysql_fetch_assoc($accident);
$totalRows_accident = mysql_num_rows($accident);

any suggestions?

Answer 1

You’re not invoking any functions that output text. Therefore, the page is blank. Simple as that.

And judging from the fact that the page is blank, it’d be safe to assume that your query successfully executed because it didn’t run die(mysql_error()), which would’ve outputted an error message if there was an error.
