Inserting into database with PHP not working - php

Question

below is my php script to input data into my database from my form. You can see my form here... http://studentnet.kingston.ac.uk/~k1202101/workshop2/CreateNewAccount.html
I get an error message when I try to submit the form. The error message I get is
'Error:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Name, Medical Information, First Name, Membership Type, D.O.B, Gender, Membershi' at line 1'
I have gone over my code but still cant see where I have gone wrong? Any help would be greatly appreciated.
<?php
define('DB_NAME', 'demo'); //**your database name
define('DB_USER','alex'); //**your user ID
//**your password
define('DB_HOST', 'localhost'); //**your local host or KU host
$link = mysql_connect(DB_HOST, DB_USER);
if(!$link)
{
die('Could not connect: ' .mysql_error());
}
$db_selected = mysql_select_db(DB_NAME, $link);
if(!$db_selected)
{
die('Can\'t use'. DB_NAME . ':' . mysql_error());
}
$value1 = $_POST['Last Name'];
$value2 = $_POST['Medical Information'];
$value3 = $_POST['First Name'];
$value4 = $_POST['Membership Type'];
$value5 = $_POST['D.O.B'];
$value6 = $_POST['Gender'];
$value7 = $_POST['Membership Referral'];
$value8 = $_POST['Trainer Required'];
$value9 = $_POST['Membership Number'];
$value10 = $_POST['Contract'];
$value11 = $_POST['House Number/Street'];
$value12 = $_POST['City'];
$value13 = $_POST['County'];
$value14 = $_POST['Postcode'];
$value15 = $_POST['Tel'];
$value16 = $_POST['E-Mail'];
$value17 = $_POST['Bank Branch'];
$value18 = $_POST['Card Holder Name'];
$value19 = $_POST['Card Number'];
$value20 = $_POST['Security Code'];
$sql ="INSERT INTO test(Last Name, Medical Information, First Name, Membership Type, D.O.B, Gender, Membership Referral, Trainer Required, Membership Number , Contract, House Number/Street, City, County, Postcode, Tel, E-Mail, Bank Branch, Card Holder Name, Card Number, Security Code) VALUES('$value1', '$value2', '$value3', '$value4','$value5','$value6','$value7','$value8','$value9','$value10','$value11','$value12','$value13','$value14','$value15', ,'$value16',,'$value17',,'$value18',,'$value19',,'$value20')";
if (!mysql_query($sql))
{
die('Error:'.mysql_error());
}
mysql_close();
?>

Answer 1

Column names with space needs to back ticks as
`Last Name`
So in the insert query you need to backtick them.

Answer 2

use back ticks, and overall check at your query :
$sql ="INSERT INTO test(Last Name, Medical Information, First Name, Membership Type, D.O.B, Gender,
Membership Referral, Trainer Required, Membership Number , Contract, House Number/Street, City,
County, Postcode, Tel, E-Mail, Bank Branch, Card Holder Name, Card Number, Security Code)
VALUES('$value1', '$value2', '$value3','$value4','$value5','$value6','$value7','$value8',
'$value9','$value10','$value11',
'$value12','$value13','$value14','$value15', ,'$value16',,'$value17',,'$value18',,'$value19',,'$value20')";
between value15 and value16 you have double , and so on between value 17 and 18.
Clean your query.
