I really have no idea where I went wrong on this, but after I got all my variables set and added I tried to echo them on the page and they won't show up and I don't know why, so please help.

 

Here's the page.

<?php session_start(); ?>
<?php

if($_SESSION['user']){

include_once('connect.php');

$session = $_SESSION['user'];

$w = $_GET['w'];

$find = "SELECT * FROM weapon_shop WHERE id = '$w'";
$run = mysql_fetch_array(mysql_query($find)) or die (mysql_error());

$weapon_id = $run['id'];
$weapon_name = $run['Weapon_Name'];
$weapon_image = $run['Weapon_Image'];
$weapon_level = $run['Weapon_Level'];
$weapon_cost = $run['Weapon_Cost'];
$weapon_sell_value = $run['Weapon_Sell_Value'];
$weapon_attack = $run['Weapon_Attack'];
$weapon_defense = $run['Weapon_Defense'];
$weapon_strength = $run['Weapon_Stength'];
$weapon_speed = $run['Weapon_Speed'];
$weapon_accuracy = $run['Weapon_Accuracy'];
$weapon_range = $run['Weapon_Range'];

$find_stats = "SELECT * FROM stats WHERE Username = '$session'";
$stats = mysql_fetch_array(mysql_query($find_stats)) or die (mysql_error());

$player_HBS = $stats['HBS'];
$player_Credits = $stats['Current_Credits'];
$player_attack = $stats['Attack'];
$player_defense = $stats['Defense'];
$player_strength = $stats['Strength'];
$player_speed = $stats['Speed'];
$player_accuracy = $stats['Accuracy'];
$player_range = $stats['Range'];

$find_duplicate = "SELECT Weapon_Name FROM weapons WHERE Weapon_Name = '$weapon_name'";
$dup = mysql_fetch_array(mysql_query($find_duplicate)) or die (mysql_error());

$weapon_name_check = $dup['Weapon_Name'];

if($weapon_name_check == $weapon_name){

header("location:weaponshop.php");

}elseif($weapon_cost > $player_Credits){

header("location:weaponshop.php");

}else{



$new_player_credits = $player_Credits-$weapon_cost;
$new_attack = $weapon_attack+$player_attack;
$new_defense = $weapon_defense+$player_defense;
$new_strength = $weapon_strength+$player_strength;
$new_speed = $weapon_speed+$player_speed;
$new_accuracy = $weapon_accuracy+$player_accuracy;
$new_range = $weapon_range+$player_range;
$new_HBS = $new_attack+$new_defense+$new_strength+$new_speed+$new_accuracy+$new_range *.3;

echo "
<html>
<img src='$weapon_image'/><br/>
$new_player_credits<br/>
$new_attack<br/>
$new_defense<br/>
$new_strength<br/>
$new_speed<br/>
$new_accuracy<br/>
$new_range<br/>
$new_HBS
</html>
";


}

}else{

header("location:index.php");
}

?>

See how this works:

<?php
error_reporting(E_ALL); //debugging remove after script works.
ini_set('display_errors',1); //debugging remove after script works.
session_start(); 
if(isset($_SESSION['user'])) {
include_once('connect.php');
$session = $_SESSION['user'];
$w = (isset($_GET['w'])) ? (int)$_GET['w'] : 0; //0 being default weapon.

$find = "SELECT * FROM weapon_shop WHERE id = '$w'";
$run = mysql_fetch_array(mysql_query($find)) or trigger_error(mysql_error());

$weapon_id = $run['id'];
$weapon_name = $run['Weapon_Name'];
$weapon_image = $run['Weapon_Image'];
$weapon_level = $run['Weapon_Level'];
$weapon_cost = $run['Weapon_Cost'];
$weapon_sell_value = $run['Weapon_Sell_Value'];
$weapon_attack = $run['Weapon_Attack'];
$weapon_defense = $run['Weapon_Defense'];
$weapon_strength = $run['Weapon_Stength'];
$weapon_speed = $run['Weapon_Speed'];
$weapon_accuracy = $run['Weapon_Accuracy'];
$weapon_range = $run['Weapon_Range'];

$find_stats = "SELECT * FROM stats WHERE Username = '$session'";
$stats = mysql_fetch_array(mysql_query($find_stats)) or trigger_error(mysql_error());

$player_HBS = $stats['HBS'];
$player_Credits = $stats['Current_Credits'];
$player_attack = $stats['Attack'];
$player_defense = $stats['Defense'];
$player_strength = $stats['Strength'];
$player_speed = $stats['Speed'];
$player_accuracy = $stats['Accuracy'];
$player_range = $stats['Range'];

$find_duplicate = "SELECT Weapon_Name FROM weapons WHERE Weapon_Name = '$weapon_name'";
$dup = mysql_fetch_array(mysql_query($find_duplicate)) or trigger_error(mysql_error());

$weapon_name_check = $dup['Weapon_Name'];

if($weapon_name_check == $weapon_name){

header("location:weaponshop.php"); //header expects a full URI.  Location must be capitalized, and a space must be after the colon.  This will insure that it works across ALL browsers.

}elseif($weapon_cost > $player_Credits){

header("location:weaponshop.php"); //see above.

}else{



$new_player_credits = $player_Credits-$weapon_cost;
$new_attack = $weapon_attack+$player_attack;
$new_defense = $weapon_defense+$player_defense;
$new_strength = $weapon_strength+$player_strength;
$new_speed = $weapon_speed+$player_speed;
$new_accuracy = $weapon_accuracy+$player_accuracy;
$new_range = $weapon_range+$player_range;
$new_HBS = $new_attack+$new_defense+$new_strength+$new_speed+$new_accuracy+$new_range *.3;

echo "
<html>
<img src='$weapon_image'/><br/>
$new_player_credits<br/>
$new_attack<br/>
$new_defense<br/>
$new_strength<br/>
$new_speed<br/>
$new_accuracy<br/>
$new_range<br/>
$new_HBS
</html>
";


}

}else{

header("location:index.php"); //see above.
}

?>
