Hello,
I'm creating a subscription form and i like to know how to create an interactive submit button.
What i want is a submit button which only can be used when they agree with the terms of conditions by checking a checkbox. Can u please tell me how i can do that???
Thanx in advance and greetz..

You would need to use JavaScript
This is the topic where u should post your question:
ClientSide Technologies
Discuss HTML/CSS/Javascript, and any other client-side technologies, here.
About the question:
There is disable <-- javascript event ...
Ohw, i'm sorry.
Im new(in coding PHP) and here at this forum and hoped there was something like this in php.
But i will look at the other topic to get some more result about the disable JAVASCRIPT EVENT. But thanx a lot for giving me some direction. I thought this would be the simplest part of my PHP form but never is ever like it seems...
Look here I made u and example of what u need:
<form>
<input type="checkbox" name="chk" value="1" onclick="return _DoSomething(this);" />
<input type="submit" name="btn" value="Bimbo :)" disabled />
</form>
<script>
var _dd = document.forms[0];
function _DoSomething(the_chk) {
if (the_chk.checked) {
_dd.btn.disabled = false;
} else {
_dd.btn.disabled = true;
}
}
</script>Have fun coding. 
hahaha... thank u very much. It works fine... Now i only have 2 figure out how it works so i can alter and use in other projects... Thank u

I am so grateful you showed us an example - wasn't sure where to look. For some reason when I tick the box to accespt the terms my button doesn't display.
I have done the same as your example.
<p><input type="checkbox" name="chk" value="1" onclick="return _DoSomething(this);" />Check to accept agreement. <a href="terms.php" target="_blank">View end user licence agreement</a></p>
<p> <input type="submit" name="btn" value="Sign Up!" disabled /></p></form>
I used the script in the header.
Any ideas why it's not working?
I don't see any <form></form> tags in your HTML code example... for bogu's code to work properly, the checkbox and submit button must be placed inside a form (the first form on the page, in fact).
EDIT: Correction, I see an ending </form> tag, but no beginning <form> tag.
I haven't included them because i didn't want to include the entire form but yes they are in form tags.
Here is the form:
<table border="0" cellspacing="0" cellpadding="0" width="450">
<tr>
<td class="pageName">Register as an Individual <p> </p></td>
</tr>
<tr><?php
include("Connections/conn.php");
$regions = @mysql_query('SELECT id, name FROM region ORDER BY name ASC');
if (!$regions) {
exit('<p>Unable to obtain region list from the database.</p>');
}
?>
<td class="bodyText"><form action="login.php?do=new" method="post">
<?php
if (isset($message_new))
echo "<tr><td colspan='2'><b>$message_new</b></td></tr>";
?>* Indicates required field.

</table>Okay.. and where do you define the _DoSomething JS function in your code?
