simple php code, but with a problem: can't receive data from variables. Need help.?

Question

Hello. I have two files:
default.html and submitform.php, they are located in C:\wamp\www\Iza\
I set up WAMPserver. when I type http://localhost/Iza/default.html , it loads my default.html - everything looks OK!

My default.html has this source:

A1:
H1:

My submitform.php has this source.



print "Hi!";
print ("Thanks for submitting your name.");
print ($a1);
print (" ");
print ($h1);

?>




But, after I press a Submit button the result is (looks like php works, but the values of variables are not received):

Hi! Thanks for submitting your name.
Notice: Undefined variable: a1 in C:\wamp\www\Iza\submitform.php on line 6
Notice: Undefined variable: h1 in C:\wamp\www\Iza\submitform.php on line 8

Why I don't get values in a1 and h1?
Thank you.

Answer 1

You have a lot of bad syntax. Look carefully at the corrected version below.



default.html:

---------------------

A1:

H1:

submitform.php:

------------------------








echo 'Hi!';

echo 'Thanks for submitting your name.' . "\r\n\r\n";

echo $_GET['a1'] . ' ' .$_GET['h1'];

?>

Answer 3

Here you are using get method to send information.

The problem is that you did not accept the two variables in to php code..

You are using GET here , so you should have some lines like :

$a1=$_GET["a1"];

$h1=$_GET["h1"];



before print($a1)



Also , when doing coding for websites, you should be stripping of unwanted characters so that

no one will be able to exploit it. Since this is fairly simple one, no need to do this here..



If you want to learn more on php, go to w3schools.com or phpf1.com

Answer 4

Remove A1: and H1: and try reloading the page.

Should use the $_GET['a1'] to retrieve the value.

Answer 5

you are not storing anything into those variables. you are storing values into the test boxes.



add this



$a1 = $_GET['a1'];

$h1 = $_GET['ha'];



place that before you print them.
