HTML Form to E-Mail

[Anon]

I'm using a PHP script to send form data as an email. How would I get a label in the e-mail to not show up if no data is entered into one of the fields of the form?

[[deleted]]

if ($field=="")
{

print it

}
else
{
#don't print it.
}

There are several ways of checking if a variable has a valid content:

"isset($var)" checks to see if the var has any value at all, including ""
"if($var=="")" checks to see if the value of $var is empty (also true if $var is not assigned)

[[deleted]]

That should be the other way around:

if ($var=="")
{
#don't print it
}
else
{
#print it
};

Piece of cake:

Assuming your form had METHOD="post".

$mailbody = 'Hi, you filled out these things in the form:\n\n';

foreach ($HTTP_POST_VARS as $var = $value)
{
if ($value != '')
{
$mailbody .= "$var = $value\n";
}
}
