Checkboxes

[Ken]

I have a two checkboxes in HTML:

<input TYPE="checkbox" NAME="cc" VALUE="true"></td><td><b>Credi t
Card</b></td></tr>

<input TYPE="checkbox" NAME="cash" VALUE="true"></td><td><b>Compa ny
Check</b>

<input type=button onClick='<?php reviewpayment() ?>' value='Continue '
style='font: 10pt Arial;

The function works if I type into the function
$cc = true;
$cash = false;

<?php
function reviewpayment() {
$validity = TRUE;

if ($cc && cash) {
echo 'javascript:ale rt(" Please select ONLY ONE type of payment ");';
$validity = FALSE; }
............... ..... ?.

Therefore the function is not receiving the input from the check boxes.

How do I structure the script and HTML to send the input cc and cash in HTML
to $cc and $cash in PHP?

I have not been able to come up with a solution.

Any suggestions?

Thanks!

You need to put the boxes in a <form></form> The form must have a
method (post or get) If register globals is on the values of the
checkboxes will be in $cc and $cash, if not they will be in the $_POST[]
or $_GET[] arrays

However, if you have two mutually exclusive choices, why not use a radio
button?

Re: Checkboxes

Geoff,

Thanks for the suggestions.

I do have the variables in between form tags. The actual script.

<form name="payment" method="post">
<table ALIGN=center border=0 cellspacing=6 cellpadding=0 bgcolor="#F6F9F 2">
<tr><td bgcolor="D2E8DF " colspan=2><b>Se lect one type of
payment</b></td></tr>
<tr bgcolor="#F6F9F 2"><td><inpu t TYPE="checkbox" NAME="cc"
VALUE="true"></td><td><b>Credi t Card</b></td></tr>
<tr bgcolor="#F6F9F 2"><td><inpu t TYPE="checkbox" NAME="cash"
VALUE="true"></td><td><b>Compa ny Check</b></td></tr> </table><br>
<center><inpu t type=button onClick='<?php reviewpayment() ?>'
value='Continue ' style='font: 10pt Arial; font weight: bold; color: 7F0738;
background: FAB918;'></center>
</form>

I checked, register_global s is on.

I have this script on the top of the page:
<?php
error_reporting (E_ALL);
// error_reporting (0);
session_start() ;
?>

The function is in file: rev.php

I have tried $_POST['cc']; $_SESSION['cc']; and $cc in the function
reviewpayment() , nothing works.

I have include("rev.ph p"); in the body of the html

File rev.php
function reviewpayment() {
$validity = TRUE;
$cc = $_SESSION['cc'];
$cash = $_SESSION['cash'];

if ($cc && $cash) {
echo 'javascript:ale rt(" Please select ONLY ONE type of payment ");';
$validity = FALSE; }
}

I appreciate your suggestions. Any other suggestions?

-----------------------------------------------------
php is new to me; I just started with php. I am familiar with JavaScript.
In JavaScript, I use alert(cc); to look at the value of variables.

I have not found a script that opens a box on the same page and displays a
variables value in php. I have tired echo, but it look as if a new page
must be opened to diplay the value.

Is there another way to display variables in php?

-------------------------------
Thanks again!!
Ken

Yeah, I was bit sleepy earlier.

First of all, forget Javascript. JS is processed on the client machine
(or not if they have it turned off). Most people using PHP only use JS
for non critical processes (e.g.rollovers) . That way, the page still
works if JS is turned off on the client machine.

PHP is processed on the server. So your function call will be parsed
when the script is delivered, not in response to an on screen event.

To run the function the page has to have two states; the first state is
all the code that is displayed before form is submitted, the second
state is what is displayed /after/ the form is submitted. Of course you
can have many more states.

So I usually do something like this. By the way, you may need to make
it a submit button, not sure about that without checking.

if(isset($_POST['continue']))
//if the button is pressed
{
//call the function
reviewpayment() ;
//clearly you do not have to use a JS popup here, you could simply print
//html to the screen
}

//display form


Hope this helps.

Oops.. That should be

if(isset($_POST['name_of_button ']))

However, this means the script only works if you press the button.
Since some people sometimes submit by pressing the enter key, you can
either check for the existence of some other variable that you know will
definitely be there if the form is submitted, or, if no such variable
exists, add a hidden field in the form and check for the existence of
that.
