Carrying a variable

[DJTim666]

I need to know how to carry a variable from one action to the next.

 

<?php

require_once("database.php");
require_once("layout.php");

echo "<h3>Profiles</h3>";

if (!isset($_POST['username'])){
echo "<form action='profile.php' method='post'>
<input type='text' name='username' /><br>
<input type='submit' value='Search' />
</form>";
}

if (isset($_POST['username'])){
$username = mysql_real_escape_string($_POST['username']);
$sql = "SELECT * FROM users WHERE username='$username'";
$result= mysql_query($sql) or die(mysql_error());
$id = mysql_fetch_array($result) or die(mysql_error());

if (empty($username)){
	echo "You left the search field blank.";
	die();
}
if (mysql_num_rows($result) == 0){
	echo "That username does not exist in our database.";
	die();
}
else {
	echo "You are searching for the username " . $username . "<br /><br />";
	echo "<a href='$PHP_SELF?profile=" . $id['id'] . "'>" . $username . "</a>";
}
}

if ($_GET['profile']){
global $id, $username, $sql, $result;
$sql2 = "SELECT * FROM users WHERE id='$id'";
$result2 = mysql_query($sql2);
$fetch = mysql_fetch_array($result2);

echo "Username: " . $username . "<br>
ID: " . $fetch['id'] . "<br>
RP: " . $fetch['rp'] . "<br>
you can put more stuff
";
}

?>

 

When I click the link of the name i am searching it displays the profile but not the values.

 

So it displays;

 

Username:

ID:

RP:

you can put more stuff

 

I want it to display;

 

Username: Test

ID: 4

RP: 245256

you can put more stuff

 

Help is greatly appreciated.

Use sessions.

If u are using the href link then use like this:

 

$name='ramesh';

<a href="secondpage.php?name=$name">Go to nextPage</a>

 

Now in the second page if u use

$name =$_GET['name'];

then u will get the value "ramesh" in the $name variable in the second page.Dont forget to set the action of the first page to the second page.
