how to difine variable that are not being submitted

[franknu]

I need to define some variable that are not being sumited through a form,

I have a link which is on page call business_display.php

when the user click on the link that match thier search

[code=php:0]

$bn = $row['BusinessName'];

echo "<a href=\"bizwebpage2.php?BusinessName=$bn\">$bn</a>";
[/code]

then that link takes the user to another page call bizwebpage2.php

where i have some variables  that  i want to display that are on the same row as BusinessName

here is the code for bizwebpage2.php
all the variables are define in page business_display and work fine

i was just wondering maybe i can use a $_session to carry the difine variables to bizwebpage.php page help please

[code=php:0]
<?php

$host = "localhost";
$username = "localhost";
$password = "abc123";
$database = "contacts";


$db = mysql_connect($host, $username, $password) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());

$BusinessName = ($_POST['BusinessName']);
$Keyword =($_POST['Keyword']);
$Picture1 =  ($_POST['Picture1']);
$Headline = ($_POST['Headline']);

Check to see if it isset

[code]<?php
if(isset($_POST['BusinessName'])){
$BusinessName = ($_POST['BusinessName']);
} else {
$BusinessName = "";
}
?>[/code]

Looks to me like you only need BusinessName from the form and everything else is coming from the table. If I am correct it should look like this
[code]<?php
<?php

$host = "localhost";
$username = "localhost";
$password = "abc123";
$database = "contacts";


$db = mysql_connect($host, $username, $password) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());

if(isset($_GET['BusinessName'])){
$BusinessName = ($_POST['BusinessName']);
} else {
die ("No Business name selected");
}
$query = "SELECT * FROM business_info WHERE `BusinessName`= '$BusinessName' ";
$result = mysql_query($query) or die (mysql_error());
$row = mysql_fetch_assoc($result);

$Keyword =($row['Keyword']);
$Picture1 =  ($row['Picture1']);
$Headline = ($row['Headline']);
$Slogan2 = ($row['Slogan2']);
$Description1 =($row['Description1']);
$Description2 = ($row['Description2']);
$Description3= ($row['Description3']);
$Contact2 =  ($row['Contact2']);
$Picture2 = ($row['Picture2']);
$Picture3 = ($row['Picture3']);
}
?>
