Having issues with code for simple add 1/subtract 1

[mbschoch]

Hello, I am learning php in a class for school and I was hoping I could get some help with some code. I am trying to make a game life counter. I just want it to have simple +1, -1 and reset buttons. I have gotten it to add and subtract the first time, but it will not continue adding/subtracting. Thank you for any help you can give. Here is the code I'm having issues with:

 

<?php

session_start();

?>

 

<form method="post" action ="">

<input type="submit" name="name" value="Add"/>

<input type="submit" name="name" value="Minus"/>

<input type="submit" name="name" value="Reset"/>

</form>

 

<?

lifeTotal();

 

function lifeTotal()

{

 

$_SESSION['total']=20;

 

if($_POST["name"] == 'Add')

{

$_SESSION['total']++;

echo $_SESSION['total'];

}

else if($_POST["name"] =='Minus')

{

$_SESSION['total']--;

echo $_SESSION['total'];

}

}

?>

The problem is that you keep resetting the total to 20.  You need to check if a total exists.  If there is NOT a pre-existing total, set it to 20.  Else, simply use what you have for the calculation.
