Having trouble passing form that consists of php variables
Question
So I have 2 pages of my multi-page form that I am using to test. When I test the first part of the form seperately, it works fine. Everything is being displayed accordingly to the information that it's retrieving from my database. Everything looks great until I click the submit button to the next page, that confirms all the values. When I try and hit submit, which is supposed to also pass the user's inputs and hold them as $_POST[], it's giving me a sever error. I'm very new to php so I'm not too familiar with everything I might need to be.
Here's my code for the first part:
<?php
$db = mysql_connect(
':/Applications/MAMP/tmp/mysql/mysql.sock',
'root',
'root'
);
if(!$db) die("Error connecting to MySQL database.");
mysql_select_db('onlineform', $db);
$newQuery = mysql_query("SELECT newPrice,numberOfWeeks FROM onlineformdata ORDER BY id DESC LIMIT 1");
$newRow = mysql_fetch_row($newQuery);
$newQuery1 = mysql_query("SELECT newCampSessions FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$newFoo = mysql_fetch_array($newQuery1);
$newQuery2 = mysql_query("SELECT pricePerWeek FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$newFoo1 = mysql_fetch_array($newQuery2);
$newQuery3 = mysql_query("SELECT numberOfSchools FROM onlineformdata ORDER BY id DESC LIMIT 1");
$newRow1 = mysql_fetch_row($newQuery3);
$newQuery4 = mysql_query("SELECT schools FROM onlineformdata ORDER BY id DESC LIMIT 1") or die('Error ' . mysql_error());
$newFoo2 = mysql_fetch_array($newQuery4);
$newOldString = $newFoo['newCampSessions'];
$newOldString2 = $newFoo1['pricePerWeek'];
$newOldString3 = $newFoo2['schools'];
$newChangedString = unserialize($newOldString);
$newChangedString2 = unserialize($newOldString2);
$newChangedString3 = unserialize($newOldString3);
$_SESSION['quickVariable'] = $newChangedString2;
settype($newRow[1], "integer");
$limit = $newRow[1];
$anotherLimit = $newRow1[0];
mysql_close();
?>

Sorry if it's too much code let me know so I can snip it down, I got penalized a lot for not providing proper information last time.
But as a more general question, is what I'm doing, about using php variables to display my form, ok? Or is that the big problem?

while (isset($_SESSION['campsessions']))
{
foreach ($weeklyPrice as $total)
{
$totalPrice = $totalPrice + $total;
}
}
This will be an infinite loop because the variable will never become unset.
Use if , not while

Your code is quite littered with errors - but I would say what is throwing the server off is that
while (isset($_SESSION['campsessions']))
as isset($_SESSION['campsessions']) equals to true you might as well have written
while(true)
which is an infinite loop. PHP will time out and give you an error. Use an if instead.
That's only one of the bad things going on though. I'm not sure why you're issuing 5 queries to retrieve 6 fields of a row in the table, and there's a if (empty($_POST['campsessions[]'])) that doesn't look right.
