collects and, in some cases, discloses information about the User. This Privacy Policy describes the information
FG collects and how that information is used.


A Special Note About Children


The nature of the service means that children are possibly the end-users of this service.
Children, however, are not eligible to use the service. FG does not knowingly solicit or collect
information from children who are 18 years or younger and asks that minors (under the age of 18)

Information Gathered


FG's main objective in collecting personal information is to provide a smooth, efficient, and customised experience. To register as an FG Member the User must choose a Username and a Password to enable him/her to check the status of their listings at any time ie. their account.

Data Security


FG secures information from unauthorised access, use or disclosure. It uses industry standard practices to safeguard the confidentiality of personal identifiable information, including 'firewalls' and Secure Socket Layers (SSL).

This simplifies the process of recording personal information, such as Password, billing addresses etc.
The User is always free to decline the cookies if his/her browser permits by setting its options so that it lets the User know when he/she receives a new cookie, or turn off the cookies completely. If the cookies feature is turned off however, the User will not be able to utilise all the special features FG offers.

Here's the problem as I see it.

The first time, the script runs, $_POST['agree'] has no value. So on that first run, this line of the script:

I agree<input type="radio" name="terms" id= "agree" value="<?php if(isset($_POST['agree']));?>"/>

Evaluates to:

I agree<input type="radio" name="terms" id= "agree" value=""/>

Thus when the script is submitted, the form element, if selected, submits a value of "".

When the form is submitted back to the script that originally produced the script, $_POST['agree'] is set, but has a value of "". So on the second run, this section of your script:

if (isset($_POST['submit']))
{ // Check if the form has been submitted
$test = $_POST['agree'];
echo"$test";

}

correctly outputs a zero-length string.

There is a difference between an unset variable and a set variable that contains a zero-length string.

Ok I think i understand but how can I fix this problem

I would have thought that if i click the radio button and

then submit the value would be set. How can I set the

variable so that it is set on submit

Cheers

 

[sleipnir214]

Oh, yeah, and another thing. Only JavaScript can reference an element's value by its id. In PHP, you must reference a value by the field's name.

Also, with a radio button, you preselect a value by setting its "checked" attribute.

I'm not sure what you're trying to do, but here is a test script I just threw together:

<?php
print '<html><body>
blah blah blah

<form action="' . $_SERVER['PHP_SELF'] . '" method="post">
Agree <input type="radio" name="terms" value="1"';
   
if (isset($_POST['terms']))
{
	if ($_POST['terms'] == 1)
	{
		print ' checked';
	}
}

print '><br>
Not agree <input type="radio" name="terms" value="0"';

if (isset($_POST['terms']))
{
	if ($_POST['terms'] == 0)
	{
		print ' checked';
	}
}

print '><br>
<input type="submit"></form></body></html>';
?>

The first time the script runs, neither button is checked. After a button is checked and the form submitted, the form is rerendered with the previous button checked still selected.
