problems passing variables from one form to another

ronanmckibbin

I finally got up and running with jerdo's help. I'm using apache, php on win xp. I have greated my first couple of scripts and they worked well. But pass variables from a form they are not recognised. I have tried both the post and get methods, checked the names are ok and even used code that I know works for others. So I guess it must be my configuration? or extensions. I only done what was require to get the basics working. I 've used the Binary version of php4. Can anyone help?
below are the files 2 I used:

oh, and is there a way to edit php files after I save them in notepad as .php?

file "loan.php"

<html>
<head>
<title>"You Better Pay Up" Loan Services</title>
</head>
<body>

<center>
<h3>Welcome to "You Better Pay Up" Loan Services</h3>

You pay us ten percent every week, or else.

My hovercraft costs $<input type="text" name="cost">
<p><input type="submit" name="submit" value="What's My Interest Payment?">

</form>

</center>

</body>
</html>

file "loanshark.php"

<html>
<head>
<title>Loanshark</title>
</head>

<body>

<?php

$interest_rate = .14;

function YouOweMe($cost, $interest_rate) {

$weekly_payment = ($cost*$interest_rate);

print "You better pay me \$$weekly_payment every week, or else!";

}

YouOweMe($cost, $interest_rate);

</body>
</html>

Could be your register_globals. Try the following for loanshark.php:

<html> 
<head> 
<title>Loanshark</title> 
</head> 

<body> 

<?php 

$interest_rate = .14; 

function YouOweMe($_POST['cost'], $interest_rate) { 

$weekly_payment = ($_POST['cost']*$interest_rate); 

print "You better pay me \$$weekly_payment every week, or else!"; 

} 

YouOweMe($_POST['cost'], $interest_rate); 

?> 


</body> 
</html>

If you use the get method for your form, just substitute $GET['cost'] for $POST['cost'].

I tried what you said but to no avail I attached a copy of the Error message. I 'm a newbie and I was wondering if it would have anything to do with my configuration?? I think I'm using php win binary version CGI. Don't laugh, I hope to understand what I'm doing before I die
I'm 18 months old :p

Can you please post the code that produced that error.

It was my code for the loan.php from before and the new code you give me , above.
I can't view the loan.php code since it was saved as a php file, or can I?
iattached it
Thanks
Ronan
sorry it won't let me attach it but it the sane as I posted to begin with.

Have you done what I suggested and changed from$ccost to $_POST['cost']?

I did exactly what you said, infact I copied and pasted your code, saving it as 'loanshark.php'
that when it started giving me the Error, when I used mine it just did n't accept the varibles but returned the proper form.
Thanks for persisting with it
the code I used the was mine only
the second time i used my loan.php and your loanshark.php
any suggestions??

The problems is in this line:

function YouOweMe($_POST['cost'], $interest_rate) {

When you create a function, you are defining the variables that will be used inside the function. PHP is complaining that "$_POST['cost']" is not a variable. Plus, you are setting $interest_rate, not passing it into the function. To avoid confusion, I would suggest that you use $fcost:

<html> 
<head> 
<title>Loanshark</title> 
</head> 
<body> 
<?php 
$interest_rate = .14; 
function YouOweMe($fcost) { 
$weekly_payment = ($fcost*$interest_rate); 
print "You better pay me \$$weekly_payment every week, or else!"; 
} 
YouOweMe($_POST['cost']); 
?> 
</body> 
</html>

The reason your code wouldn't work originally is because register_globals is turned off. That's a good thing. You should always use $POST or $GET when referring to passed variables, and never rely on register_globals being set to ON.
