define variable not in form

[Dutch_MaFia-boy]

I want a variable to be printed out in a text file - its not going to be passed from a form but it does exist within the same document. So far the below is not printing out the $total variable in the text file.

The following exists in a file called processorder.php.

thanks.

$orderfile = 'orders.txt'; //file location - /wwwroot
$ordercontent = $date."\t".
                $tireqty." tires \t".
                $oilqty." oil \t".
                $sparkqty." spark plugs \n"; 
                print $total;  //" total:  \t".

The $total variable isn't being declared anywhere in the snippet you have provided here. Show us the applicable portion of code where the $total variable is being declared.

$total = "Hello World!";
print $total;

// Outputs:  Hello World!

We can't help if we don't see the code where it's being declared.

$date = date("l dS of F Y h:i:s A");
//echo date("l dS of F Y h:i:s A");

## The switch statment works similar way to the if statement, but allows the           ##
## condition to take more than two values.  In a if statement, the condition can       ##
## be either true or false.                                                            ##                                           
## In a switch statement, the condition can take any number of different values,       ##
## as long as it evaluates to a simple type (integer, string, or double).  You need    ##

## optionally, a default case to handle any that you do not provide a specific case    ##
## statement for.                                                                      ##

OK, Let's look at this part of your code only, which is at the top of your file...

<?php 

$date = date("l dS of F Y h:i:s A"); 
echo date("l dS of F Y h:i:s A"); 

## The $tireqty, $oilqty, and $sparkqty are passed from the form - orderform.html 

$orderfile = 'orders.txt'; //file location - /wwwroot 
$ordercontent = $date."\t". 
                $tireqty." tires \t". 
                $oilqty." oil \t". 
                $sparkqty." spark plugs \n";  

                print $total;  //" total:  \t". 
                print $address; //." address \n";

• 1st, you define the $date variable, and echo it.

• Next, you define the $orderfile variable.

• Next, you define the $ordercontent variable using your $date, $tireqty, $oilqty, and $sparkqty variables. The $date, you defined above, and the other three come from the form posting to this file.

• Next, you try to print the $total variable, but it is never defined prior to trying to print it out. There is no reference to it being posted from the form, and there are no calculations in this script for it, and there is nothing like I showed you in my first response.

• It's the same thing with your $address variable. It is never defined prior to trying to print it out either.
