Variable Addition?

dhelsdon

I am wondering why $ResultGD and $ResultAD don't add like the rest of my variables? I have commented the problematic lines, The information is coming from a form. I was experimenting with those lines to see if the order effected it, that's why ResultGD and ResultAD are different.

<?php

$Spear = $_POST["Spear"];
$SpearGD = 15;
$SpearCD = 45;
$SpearAD = 20;
$ResultSpearGD = $Spear * $SpearGD;
$ResultSpearCD = $Spear * $SpearCD;
$ResultSpearAD = $Spear * $SpearAD;
/*$ResultSpearGD+$ResultSwordGD+$ResultAxeGD+$ResultArcherGD=$ResultGD;
$ResultAD= $ResultArcherAD + $ResultSpearAD + $ResultSwordAD + $ResultAxeAD;*/

echo "<h4><u>Spear</u></h4>";
echo "Total GD: $ResultSpearGD<br>";
echo "Total CD: $ResultSpearCD<br>";
echo "Total AD: $ResultSpearAD<br>";

$Sword = $_POST["Sword"];
$SwordGD = 50;
$SwordCD = 15;
$SwordAD = 40;
$ResultSwordGD = $Sword * $SwordGD;
$ResultSwordCD = $Spear * $SwordCD;
$ResultSwordAD = $Spear * $SwordAD;

echo "<h4><u>Sword</u></h4>";
echo "Total GD: $ResultSwordGD<br>";
echo "Total CD: $ResultSwordCD<br>";
echo "Total AD: $ResultSwordAD<br>";
echo "<br>";

$Axe = $_POST["Axe"];
$AxeGD = 10;
$AxeCD = 5;
$AxeAD = 10;
$ResultAxeGD = $Axe * $AxeGD;
$ResultAxeCD = $Axe * $AxeCD;
$ResultAxeAD = $Axe * $AxeAD;

echo "<h4><u>Axe</u></h4>";
echo "Total GD: $ResultAxeGD<br>";
echo "Total CD: $ResultAxeCD<br>";
echo "Total AD: $ResultAxeAD<br>";

$Archer = $_POST["Archer"];
$ArcherGD = 50;
$ArcherCD = 40;
$ArcherAD = 5;
$ResultArcherGD = $Archer * $ArcherGD;
$ResultArcherCD = $Archer * $ArcherCD;
$ResultArcherAD = $Archer * $ArcherAD;


echo "<h4><u>Archer</u></h4>";
echo "Total GD: $ResultArcherGD<br>";
echo "Total CD: $ResultArcherCD<br>";
echo "Total AD: $ResultArcherAD<br>";
echo "<hr>";
/*echo "General Defense: $ResultGD<html>&nbsp;&nbsp;&nbsp;&nbsp;";
echo "Archer Defense: $ResultAD<html>&nbsp;&nbsp;&nbsp;&nbsp;";	
echo "Cavalry Defense: $ResultCD<html>&nbsp;&nbsp;&nbsp;&nbsp;";*/

Well...the "=" operator is directional: whatever is on the right side gets assigned to what is on the left side, so the first commented line would not work as I am assuming you want it to.

The 2nd line is syntactically correct, but at least in the sample code not all of the variables appear to be defined yet, so they'll probably default to 0 when cast to a numeric type.

If where you have those lines commented out is correct, then the reason they don't have the right totals is because you calculate them before you've calculated any of the numbers that you're trying to add (except for spears).

The reason that the second part doesn't work is that it requires values from the first part, which doesn't work either. What would be a proper way to add all those variables?
