Excluding form fields if values are empty

[KHurst]

I have created a form that I email the submitted results to an email address. The form has several optional fields that I would like to exclude from the sent email if they are empty. Below is the PHP code that I am using now.

foreach ($_POST as $field=>$value)
$message .= "$field: $value\n";
mail($to, $subject, $message);

Try this:
[php]
if(!strlen(trim($_value)) < 1)
{
# do mail
}
[/php]
Regards :)

Just to help the next person. This is the code that worked for me. Thanks!


foreach ($_POST as $field=>$value)
if(!strlen(trim($vlaue)) < 1) {
$message .= "$field: $value\n";
}
mail($to, $subject, $message);

Sweet!

Remember to use code tags when posting code, though.

See you around dude!
