Adding form values to an array and email

gfd

Hello,

I would like to store certain form values in an array and email them.

This is simplified version of my form senario, so that you can understand what I'm doing.

A user selects the number of passengers and clicks 'next'. The next page displays the appropriate number of fields for the passenger names.

The loop I use to do this is this:

for ($i=1; $i<=$passengers; $i++) {

	$fields = "<p><label for='name$i'>Passenger $i:</label>
						<input name='pass$i' id='pass$i' type='text' size='20' /><p /> ";
	echo $fields;
}

I would now like to email these contents.
I believe that since the number of fields varies, the best way to do this is to use a loop to store these values in an array variable, and then include this array variable with the rest of the contents to be emailed.

The problem is that I have been continuously failing to achieve this.

Can someone help?

thanks in advance

assuming the number of passengers is coming as a POST var called "num_passengers":

<?
echo '
<form action="" method="POST">
please enter passenger names:<br>
';

for ($i = 1; $i <= $_POST['num_passengers']; $i++)
{
	echo $i . '. <input type="text" name="passengers[]"><br>';
}

echo'
<input type="submit" name="submit" value="submit">
</form>
';

if (isset($_POST['submit']))
{
	$_POST['passengers'] = array_map('stripslashes', $_POST['passengers']);

$to = 'gfd@gfd.com';
$subject = 'passenger names';
$message = 'here are the names fo the ' . count($_POST['passengers']) . ' passenger(s) that were entered' . "\n\n" . implode("\n", $_POST['passengers']);

$mail = mail($to, $subject, $message);
if ($mail) {echo 'mail send OK';}
else {echo 'mail send FAIL';}
}
?>

that's exactly what I needed. Excellent, thank you very much.

I'd like to ask for one more thing.... if you have the time...

Do you by any chance know how I can check to see if all of the name fields have been entered, before the email is sent?

I can do it for one field at a time, with "isset" or "empty", but I don't know how to do it with these dynamically generated fields.

..... I could of course add about 50 "isset" functions in the validation code....... but something tells me there must be a better way.

Your help is very much appreciated.
Thank you

foreach ($_POST['passengers'] as $value)
{
	if (!$value)
	{
		echo 'you forgot to fill in all names';
		break;
	}
}
