Question

PHP Losing Data

Asked by: precision

I have a PHP file that contains hidden form tags:

<input type="hidden" name="toname1" value="<?=$_POST['Name']?>">
<input type="hidden" name="tomail1" value="<?=$_POST['tomail1']?>">

Once the form posts, output code is:
file.php?toname1=".$_POST['toname1']."&email=".$_POST['tomail1']."

Issue: If I put in "Harry" for toname1, the data transfers just fine.
But when I put in "Harry Jones", I just get Harry and lose anything after the space.

????? LOST, HELP!

You need to use the function rawurlencode( ) on the URL to replace all special characters (such as the space) with their % equivalents.

and then rawurldecode( ) if you need to retrieve info from the URL in the called script.

Great, but how do I implement on above?  Seems very confusing, I am not a PHP expert.

 

by: yodercmPosted on 2007-01-10 at 18:11:42ID: 18289704

I assume this is a URL that you construct from the user input in the form?

file.php?toname1=".$_POST['toname1']."&email=".$_POST['tomail1']."


First of all, I would not use $_POST right in the url to start.  I'd make variables that I could check, especially since they are user-input.

So my action script for the form would start with

$toname1 = $_POST['toname1'];
$tomail1 = $_POST['tomail1'];

and then I'd do some verification on these variables, depending on what you intend to do with them.  Make sure they have no special characters if you will be using them in database queries, etc.

Once you have your variables set, then use THEM in constructing the URL.

$url = rawurlencode("file.php?toname1=$toname1&email=$tomail1");


Then in file.php,

$toname1=rawurldecode($_GET['toname1']);
$tomail1=rawurldecode($_GET['email']);


I have not run this code, so I won't swear by correctness, but this is the approach I think you need.  The rawurlencode and rawurldecode simply replace and unreplace all special characters with the % equivalents for use in a url.

So your name 'Harry Jones' would be passed on the URL as

file.php?toname1=Harry%20Jones&email=etc....

Please feel free to ask further if you don't understand.

You shoulodn't urlencode the whole url, just the vars send with it, so instead of using:
$url = rawurlencode("file.php?toname1=$toname1&email=$tomail1");

you should do it like this:

$toname1 = urlencode($_POST['toname1']);
$tomail1 = urlencode($_POST['tomail1']);

$url = "file.php?toname1=$toname1&email=$tomail1";


Then in file.php,

$toname1=urldecode($_GET['toname1']);
$tomail1=urldecode($_GET['email']);

Yeah, terref is right, I woke up this morning thinking that what I wrote would encode the . and the ? and popped in here to correct it.  Thanks, terref!
