Question

Can anyone see why i am getting the following error when i try to submit this? I know the whole null vs ” thing but I don’t have any ” that should be causing this. New to mySQL so any help would be great.

Incorrect integer value=” for column ‘two’ at row 1

<?php

$db_host = "localhost";
$db_username = "TEST";

$db_pass = "example";

$db_name = "questions";

@mysql_connect("$db_host","$db_username","$db_pass") or die ("Could not connect to MySQL");
@mysql_select_db("$db_name") or die ("No database");


if ($_POST['parse_var'] == "contactform"){


$oneField = $_POST['one'];
$twoField = $_POST['two'];
$threeField = $_POST['three'];
$noneField = $_POST['none'];
$surveyField = $_POST['survey'];
$questionField = $_POST['questions'];
$guestField = $_POST['guest'];
$homeField = $_POST['home'];


$selected_radio = $_POST['radio'];
  if ($selected_radio == 'one') 
  {
  $oneField = '1';
  }

  else if ($selected_radio == 'two') 
  {
  $twoField = '1';
  }

  else if ($selected_radio == 'three') 
  {
  $threeField = '1';
  }

  else if ($selected_radio == 'none') 
  {
  $noneField = '1';
  }


if($surveyField == "yes"){
$surveyField = "1";
 } 
if($mysqlField == "yes"){
$mysqlField = "1";
 } 
if($guestbookField == "yes"){
$guestbookField = "1";
 } 
if($homeField == "yes"){
$homeField = "1";
 } 

$sqlUpdate = mysql_query("INSERT INTO questiondata (one, two, three, none, survey, 
       question, guest, home)
 VALUES  ('$oneField','$twoField','$threeField','$noneField','$surveyField','$questionField','$guestField','$homeField')")
 or die (mysql_error());
}
?>

You’re trying to INSERT with one of the integer arguments being empty, i.e.:

INSERT INTO questiondata (one, two) VALUES ('1','')

This will not work unless one or two are string fields.
Modify your code so empty variables will be initialized:

$oneField = isset($_POST['one']) ? $_POST['one'] : 0;
$twoField = isset($_POST['two']) ? $_POST['two'] : 0;
