I have an exisitng php script (open source), but am not up to scratch with the subject yet (will be taking a course on the subject in the near future).

I wish to simply add a checkbox to the script so that the result will be posted via email - the checkbox will be a very basic one:

Tick here to join mailing list

I've scoured the web and get one to work, but only to post results on screen using echo command.

Please help

In order to help you, we would need to know what the current script is doing (is it already e-mailing someone else, and you just need to add a recipient, etc). Since it's open source, can you list which one it is?

Basically in a nutshell, assuming you are already collecting the needed information, add the checkbox:

<input type="checkbox" name="chkSubscribe" value="join" id="chkSubscribe">
<label for="chkSubscribe">Tick here to join mailing list</label>

Then in the PHP, do a check for that value being set:

if ($_POST['chkSubscribe']=='join') {
   // Code to e-mail you their info
   // (see for some samples)

Code for simple HTML Script :->

Code for simple PHP Script :->

if ($_POST['chk_box']=='enter')
// Code which you want to execute.
Explanation here $_POST[] is an global variable, and $_POST['chk_box'] means it retrieve the value of check box on client side then check it at server side by value enter.
actually it $_POST[] create an array

Like array
$_POST['chk_box'] is equivalent to $_POST[index of array 0] = value i.e. enter
