For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Data can't be inserted into Access database

Posted by Jo (Jo), 8 July 2008
Hi everyone, I'm currently doing a online personal information registration form and currently in need of some help. My form has the form and a confirmation page. After the user clicks submit on both pages, it would store the data into the database. However I'm not able to store it in the database. After clicking submit, it would insert blank data and in the browser, it would say all the variables are undefined. The connection to the database is ok as I'm able to read data from it.
This is the code I use to submit data into the database.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
$_POST['username'] = $username;
$_POST['admin'] = $admin;
$_POST['gender'] = $gender;
$_POST['address'] = $address;
$_POST['hometel'] = $hometel;
$_POST['hp'] = $hp;
$_POST['email'] = $email;
$_POST['course'] = $course;
$_POST['year'] = $year;
$_POST['path'] = $path;
$_POST['title'] = $title;
$_POST['supervisor'] = $supervisor;

echo "Data has been submitted";

function Enter_New_Entry($username,$admin,$gender,$address,$phone,$hp,$email,$course,$year,$path,$title,$supervisor) {

  if(!$cnx = odbc_connect( 'FYP' , 'root', '' ))die("error with connection");
   $SQL_Exec_String = "Insert Into rank (username,admin,gender,address,hometel,hp,email,course,year,path,title,supervisor)
           Values ('$username','$admin','$gender','$address','$phone','$hp','$email','$course','$year','$path','$title','$supervisor')";

   $cur= odbc_exec( $cnx, $SQL_Exec_String );
   if (!$cur) {
       Error_handler( "Error in odbc_exec( no cursor returned ) " , $cnx );

   odbc_close( $cnx);


Any advice would be helpful. Thank you.

At a first glance, it looks as if your assignments are the wrong way round ...

$_POST[xxx] = $xxx;

should read

$xxx = $_POST[xxx];

i.e. copy the incoming form variables into local variables of the same name.
