I have searched these forums and i cant find what i need cause im new to PHP and all the stuff here is way over my head lol. Anyway thanks for looking at my post. Basically what i want to do is submit a username within a form on a HTML form and pass that value into a variable within a PHP file which works a few things out about that username.

 

I then want it to redirect to another webpage where the variables from the PHP file can be used by using the <? echo $variable ?> command. I will now show you my code to see if you can spot the problem  :shrug:

 

Heres the first page where the username will be submitted:

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<form action="phpfindingdetails.php" method="post" name="form"><input name="username" type="text" value="username" /></form>
</body>
</html>

 

This is the PHP file used to work a few things out, basically what it does is grabs a certain string within the source code of an external webpage and stores it in a variable. It also works out the url for that users profile:

<?php  

header("Location: /Untitled-4.html");
$name = $_POST['username'];
$url = 'http://www.url.co.uk/home/';
$userprofile = $url.$name;
$raw = file_get_contents($userprofile);

$newlines = array('\t','\n','\r','\x20\x20','\0','\x0B');
$content = str_replace($newlines, '', html_entity_decode($raw));

//----------------------------------------------------------------


$mottostart = '<div class="profile-motto">';
$mottoend = '<div class="clear"></div>';




//-----------------------------------------------------------------

function get_string_between($string, $start, $end){ 
    $string = ' '.$string; 
    $ini = strpos($string,$start); 
    if ($ini == 0) return ''; 
    $ini += strlen($start); 
    $len = strpos($string,$end,$ini) - $ini; 
    return substr($string,$ini,$len); 
} 

//-----------------------------------------------------------------

$motto = get_string_between($content, $mottostart, $mottoend); 



?>

 

This is the page which i want to use the variables from the previous PHP file, but it seems as if the PHP file hasn't been included properly. This page displays an iFrame of an external website within my HTML page:

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<?php include ("phpfindingdetails.php"); ?>



<div style="overflow: hidden; width: 270px; height: 296px; position: relative;" id="i_div">
<iframe name="i_frame" src="http://www.url.co.uk/home/<? echo $userprofile ?>" style="border: 0pt none ; left: -630px; top: -158px; position: absolute; width: 1276px; height: 615px;" scrolling="no"></iframe></div>
</body>
</html>]

On the page you want to have the username displayed you have to GET the variable from the form.  You are using the POST method so you would need to do this.

 

if (isset($_POST['username'])) {

    $username = $_POST['username'];

} else {

    $username = "";

}

 

now $username variable has a value that was passed from the form.  hope this helps.

Didn't he already do that? $name = $_POST['username']; in the phpfindingdetails.php page?

The phpfinddetails.php is the second piece of code i showed you in my post. Oh and thanks tomtimms ill try this out and get back to you right away :)

 

Right, I get that... what I was talking about was this piece:

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<?php include ("phpfindingdetails.php"); ?>



<div style="overflow: hidden; width: 270px; height: 296px; position: relative;" id="i_div">
<iframe name="i_frame" src="http://www.url.co.uk/home/<? echo $userprofile ?>" style="border: 0pt none ; left: -630px; top: -158px; position: absolute; width: 1276px; height: 615px;" scrolling="no"></iframe></div>
</body>
</html>]

 

If that is a .html file, it won't recognize the <?php include ("phpfindingdetails.php"); ?> part. You have to tell your server to parse PHP code in .html files as well if you want to do that, otherwise the file will need to be a .php file.
