问题
Found this on the internet. How can I put this output into an email? Normally I use
$name = $_POST['name'];
$email_body = "$name";
I would like the output of this code into my $email_body. Is this posible?
<?php
$aDoor = $_POST['formDoor'];
if(empty($aDoor))
{
echo("You didn't select any buildings.");
}
else
{
$N = count($aDoor);
echo("You selected $N door(s): ");
for($i=0; $i < $N; $i++)
{
echo($aDoor[$i] . " ");
}
}

$name = $_POST['name'];
$email_body ='';
<?php

{
$email_body = "You didn't select any buildings.";
}

$email_body .= "You selected $N door(s): ";
