Add field only if it has a value

[Anon]

I have one form with the following fields:

name1, company1, email1, name2, company2, email2...5

This form calls a page with a php script that mails me the fields filled on that form, using the mail command.

However, I only want to see those fields if they have an entry.

I want to receive something in the following format:

Name: (will show name1 or name2 etc. depending on which fields have a value)
company: $companyX
email: emailX

The chances are that I will only get one batch of fields with values, but someone may inadvertantly enter something in email2 and name4, company4. I need to trap for this.

The page in question is www.access-programmers.co.uk/contact-test.htm

How can I add these fields to my email only if they have a value?

Hope that made sense.

Thanks,

Jon

If you are familiar with the mail function in php, you can build the body of your email after testing for null values, one way to do this that I like to use is looping through the post vars and assigning them to the variable $body

while (list ($key, $val) = each ($HTTP_POST_VARS)) {
if (($key != "submit") && ($val != "")) {
$body .= sprintf('%s: %s %s', $key, $val, "\n");
}
}

Now you have the variable $body containing each non empty value separated by a newline character except for the submit button if you name it "submit". By the way I am not sure what the newline character is going to look like in this forum but it should be a forward slash followed by an "n" the third argument in the sprintf statement
