Php sql'；整数值不正确'；消息

当我试图提交此文件时，有人能看到我为什么会出现以下错误吗？我知道整个空对''的事情，但我没有任何''应该导致这一点。mySQL是新手，所以任何帮助都会很好

第1行“2”列的整数值=“”不正确

<?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());
}
?>

列“2”是一个整数列，很明显，您试图在其中插入一个空字符串

检查空字符串，并将其替换为另一个值或null（如果该列可为null）

PS：我建议对其他字段也这样做。
您试图插入一个整数参数为空的

，即：

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

除非

one

或

two

是字符串字段，否则此操作无效。
修改代码，以便初始化空变量：

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

---

尝试删除insert语句中的“”并将所有字段初始化为NULL（大小写无关紧要）。

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