Remove empty fields from a form.

[HHawk]

Hi there,

I have a question regarding forms.
Currently we receive forms from our website, which is great and stuff, but there a lot of empty fields on our forms (since they are not all required to be filled in).

Is there a way to remove the empty fields completely before the form in sent by email?
So we get a cleaner order form by email?

Please advice and thanks in advance.

[code]depends on how you process your form. if its just a case of you printing out each field in the form and its value then you could try:

[code]

$form_data = NULL:
foreach($_POST as $key => $val);
{
if (!empty($val))
{
  $form_data .= $key . ": " . $val . "\r\n";
}
}
[/code]

then just email yourslef the $form_data string.
[/code]

Well it's just a simple html form... Don't know if that information matters?

[ToonMariner]

well you can only remove that information if it is processed by a server side script like php or asp other wise what you get is what you get.

Actually, SOMETHING processes the form and submits the data (variables).

Even using a straight sendmail cgi determines the format sent.

Unless you are using some scarey FrontPage extension thing.

well if you can edit that script then you strip out the rubbish.

If you really, really care, you could disable the inputs via JS before it gets submitted.
