This is the first page of my website(AssociationAdd.php). When I clicked the 'Add' button, it shows that :
"Notice: Undefined index: T2 in c:\easyphp1-8\www\efiling\associationaddprocess.php on line 19

Notice: Undefined index: T1 in c:\easyphp1-8\www\efiling\associationaddprocess.php on line 20"

Your not going to get any help with a post like that. Try telling us what you are trying to do, and what your problem is.

The HTML code is 1996 abysmal.

Get rid of all the font elements, center tags, and the miles of non-breaking spaces and do the job properly.

You have spaces in URLs. That is always a very bad idea.

There's a lot more at stake than is suggested by your original question.

Here's basically where the errors come from: In your initial script (AssociationAdd.php), if $submit is 'Add' you redirect the user to AssociationAddProcess.php with the values for T1 and T2 specified in the URL (?T1=$T1&T2=$T2) so when AssociationAddProcess.php is called, these values are stored in $_GET and not $_POST.

So you need to change lines 19 and 20 of AssociationAddProcess.php to:

$id = $_GET["T2"];
$an = $_GET["T1"];

Hope this helps. BTW, i'd suggest you name your buttons something other than "submit". In Javascript, all forms have a function called submit() that you may want to use in the future, and a button called "submit" overrides this function. You may want to give unique names to those submit buttons, i like using "op_add" and "op_back" etc:

echo"<p>&nbsp;<input type='submit' value=' Add ' name='op_add' ...
echo"<input type='reset' value=' Reset ' name='B2' ...
echo"<input type='submit' value=' Back ' name='op_back'...

Then in your PHP script you can simply check for isset($_POST['op_add']) and isset($_POST['op_back']).

Not by any chance trying to get help with a phishing expedition, are you?

This problem was solved, thank for your help.
Just like idfer said, change the lines 19 and 20 to :

$id = $_GET["T2"];
$an = $_GET["T1"];

But now I am facing another problem, SQL select statement failed. Before that I could connect to database, is that any problem in my coding?

Your best bet is to echo your sql query into your page and paste that into a mysql shell and see if that helps you find the error.

I have test it and I discover that my error is here :

if (mysql_num_rows($result2) < 1)
{
$sql = "INSERT INTO association(Index, AssociationName) VALUES ('$id', '$an')";
$result=mysql_query($sql)
or die("<font color='#FFFFFF'>SQL select statement failed</font>");

But I checked my database, there is no wrong typing I think. May I know what is the problem? Below is print screen of my databse.

I was solved the problem.
Don't know why I can't use 'Index' as my field in database, after I changed my field name then no problem already. Thanks for helping. :)

Index is a reserved word in SQL, you can see MySQL's list of reserved words here: [dev.mysql.com...]

There are quite a few of them. To avoid this kind of problem, i usually try to use field and table names containing an underscore.

You define $T2 in your if isset but then output it outside of that if statement
if(isset($_POST["submit"]))
{
$submit = $_POST["submit"];
$T1 = $_POST["T1"];
$T2= $_POST["T2"];
if($submit==" Add ")
{

print "<script language ='javascript'>window.location.href='AssociationAddProcess.php?T1=$T1&T2=$T2'</script>";

Basically your script is saying that there is no varaible $t2 because your if(isset must not have returned true. I hope this helps.
