I have data being passed via HTTP post to another page. Essentially passing data from one server to another. On the target page, I cannot get the URL variable to be seen by php. Am I doning something wrong? Is there a better way to do this?

URL string:

form_listener.php?
contactId=101460&inf_custom_ddState=IN&inf_custom_txtZipCode=46268&inf_custom_ddClientDegreeId=729&inf_custom_txtCity=indianapolis&inf_custom_txtLastName=Anderson&inf_form_xid=f28acf3ff321cb273cb4696e996008e0&inf_custom_ddStartSemesterYear=Fall2012&inf_custom_ddMilitaryAffiliation=Yes&infusionsoft_version=1.23.11.30&inf_custom_txtFirstName=someone&inf_custom_txtAddress2=&inf_custom_txtAddress1=4707+East+72nd+Street&inf_custom_ddHSGradYearCustomLiberty=2011&inf_form_name=LibertyOnline&inf_option_Signmeupforthenewsletter=432&inf_custom_txtEmailAddress=killing.fields%40gmail.com&inf_custom_affiliateid=D80576&inf_custom_ddEducationLevel=CLGJ&captcha.typed=jydqb

PHP Code: 

$ddState= $_GET['inf_custom_ddState'];

echo $_GET['ddState'];

?>

  • your url is 684 characters long. You might have issues as it contains more than 255 car. No, seems like I was wrong: http://stackoverflow.com/questions/417142/what-is-the-maximum-length-of-a-url – JMax Nov 21 '11 at 13:18

    I think that last line should be `echo $ddState`? – Explosion Pills Nov 21 '11 at 13:18
  • @JMax standards don't put any limit on URL length, but some browsers put an artificial limit. IE is the lowest that I know, with only 4096 chars. – Explosion Pills Nov 21 '11 at 13:19
  • @tandu Servers can limit it as well; see http://stackoverflow.com/q/1289585/212218 –  Nov 21 '11 at 14:54

You don't have ddState in the URI. You want: echo $ddState; (because that is the variable where you copied the data to) or rather (to avoid opening up an XSS security hole) you actually want:

echo htmlspecialchars($ddState);

$ddState= $_GET['inf_custom_ddState'];

echo $ddState;
// or 
echo $_GET['inf_custom_ddState'];

When you use $_GET you are telling php that the variable is from the URL. By doing this:

$ddState = $_GET['inf_custom_ddState'];

you are "creating" a local variable ($ddState) with the content of $_GET['inf_custom_ddState'], so you don't have to use $_GET variable anymore.

So your echo can be in 2 ways:

  1. echo $_GET['inf_custom_ddState'];
  2. echo $ddState;

you can use either this way 

echo $_GET['inf_custom_ddState'];

Or

$ddstate=$_GET['inf_custom_ddState']; 
echo $ddstate;

Your echo should just be echo $ddState;

You are assigning the value of the URL variable to a local variable. Once that's done, you are dealing with something that is locally scoped.

As the $_GET and $_POST are global array, you can use the following code to see the values:

echo "<pre>Get data</pre>";
print_r($_GET);
echo "<pre>Post data</pre>";
print_r($_POST);

Check whether these variables are set in the request. If not, try to use the post method, as it can hold more data than get method.

First of all, make sure that your page is getting request parameters. Try $_REQUEST['inf_custom_ddState'] or print all variables using print_r($_REQUEST).

$_REQUEST is an associative array that by default contains the contents of $_GET, $_POST and $_COOKIE. If anyting is passing to page then it should get printed.
