Mmm, you might be better doing this with Javascript. It would be more instantaneous and you wouldn't have to pass any variables back to the page.

thanks for the response, can you give me a link on this javascript..

there's a thing about Javascript form validation here: http://www.w3schools.com/js/js_form_validation.asp

in case you decide to do this with php heres the logic behind it.

1) tick box to aggree to terms and conditions "posts" value "terms" to your php script.

2) vale $_POST['terms'] is set = to $terms

3) php script checks to see if the variable $terms is set to 1. if it is then the rest of the script is processed/

4) if not set a $_SESSION['terms_error'] and pass it back to the main page using the header() function.

5) once back on the main page chck to see if $_SESSION['terms_error'] isset and if it is you echo out "you must aggree to the terms and conditions"


heres some code that should do what you want... it might need some modification as this is off the top of my head... if u have any problems ill try and fix it.

ok here is the page containing the form that allows people to register. Note that it also contains some php if else statement.... but we shall come back to those later.

Code: Select all

<?php
if(isset isset($_SESSION['terms_error']))
{
@$terms_error = $_SESSION['terms_error'];

if ($terms_error != ""){
echo "<h4>Registration Error</h4>";
echo "<strong>You must aggree to the terms and conditions, Please try again.</strong>";
$_SESSION['terms_error'] = "";
}
}
?>

<form method="POST" action="adduser.php">
Desired User Name<input type="text" name="username" size="30" maxlength="25" />
Desired Password<input type="password" name="password" size="30" maxlength="25" />
I aggree to the Terms & Conditions <input name="terms" type="checkbox" />
<input type="submit" name="submit" value="Join Now" />
</form>

I havnt include all of the neccessary html headers and tags.. body etc... so ull have to slot the above into an existing document, or add those bits seperatly.

ok, now, heres the php file that processes the registration

Code: Select all

<?php
$username = $_POST['username'];
$password = $_POST['password'];
$terms = $_POST['terms'];

if ($terms != "on") {
$_SESSION['terms_error'] = "1";
header("location: registration.php");
}
else {

// Add the info to the database... send emails... whatever in there... or even perform more checks on passwords etc.


}//if terms are aggreed if
?>

hope that makes sense

notice the headers sending back to the first page if the terms were not aggreed.... any problems let me know

I'd say do it with both PHP and JavaScript.

[csun]

thank you for the response i really appreciate it.. It really helps me here..

Advantage of using JS is that you can keep the fields filled in even afetr the error has been passed .... so mabye a combination is best.

I havnt found a way to refill the fields after moving the user back to the form, but then a signup form should only be a small afair.

If anyone knows how to do this without the use of JS id really appreciate the info.

[Steve Mellor]

I know

Well this is what I use anyway. Without giving you a load of code, I'll just go through the process I use.

Code: Select all

<form name="form" method="post" action="contact.php">

in the head of the document you detect whether the form has been submitted.

PHP: Select all

if(isset($_POST['name'])) 

then you do the tests to make sure the form is valid, however you want to do that. Then if the form is valid, perform whatever process you want and exit() the page.

Now, below that, of course, would be the form. You'd only exit the page if the code is valid. If not the form is displayed again and you can use code like:

PHP: Select all

<input id="name" name="name" class="boxes" type="text" <?php if(isset($_POST['name'])){echo 'value="'.$_POST['name'].'"';}?> />

... to display the returned form data and set up a query string that tells the user what the problem is.

It's not the most elegant solution I'm sure, but it works rather well.

yeah that would work ..... dont know why i didnt think of it myself... thanks

[Steve Mellor]

To be honest, it's something I struggled with myself for ages, coming up with more and more complex solutions for it that never seamed to work correctly. I suppose the solution is just to go back to basic principals and write down what you want to do and in what order.
