Ignore 'CC' field in Form Post if left 'blank'

[NGJ]

I'd like to give the user an option of specifying a value for a 'cc' email address on a form.
What I'd like to do is to be able to see if a value has been entered into this field. If it is blank then I need the code to ignore the 'cc' declaration.

I cannot change the mail.asp we're using - if I declare the cc field and submit a blank then this generates a error email (and grief for me! )

Can anyone help please?

Thanks in advance,

N.

Can you do a:

if (cc!=='')
code here to declare the cc field

Where cc is the value of a text input where the user enters the cc addresses if desired.

So, given that I'm using "mailto" and "mailcc" as the two holders, would it look something like this:

-----------------------------------------------------------
<form name="example" method="post" action="/lib/common/mailing.asp">
<input type="text" name="cc">
<input type="hidden" name="mailto" value="my.usual@email.co.uk">

if (cc!=='') <input type="hidden" name="mailcc" value="cc">

... << the main form elements here >> ...

<input type="Submit" value="Submit">
-----------------------------------------------------------

I am not familiar with the use of IF statements within HTML yet (this will help me learn!) but I'm sure I'm not doing this right! Do I need to enclose the overall statement in brackets or something?

Thanks again for your help,

If cannot generally be used in HTML (with specific exceptions, this not being one of them). It can generally be used in javascript, try this:

<form name="example" method="post" action="/lib/common/mailing.asp">
<script type="text/javascript">
function createCC(el){
if (el.value!==''&&!document.getElementById('cctestid')){
var theCC=document.createElement('input');
theCC.name='mailcc';
theCC.value=el.value;
theCC.type='hidden';
theCC.id='cctestid';
el.parentNode.appendChild(theCC);
}
else if (el.value!=='')
document.getElementById('cctestid').value=el.value;
else if (document.getElementById('cctestid'))
document.getElementById('cctestid').parentNode.removeChild(document.getElementById('cctestid'));
}
</script>
<input type="text" name="cc" onchange="createCC(this);">
<input type="hidden" name="mailto" value="my.usual@email.co.uk">


... << the main form elements here >> ...

<input type="Submit" value="Submit">

That works just fine!!

Thanks for the help on this one - really useful !!
