That's because you're concatenating. When appending to a
variable, you can't use constructs and conditions, unless using
ternaries:
. (!empty($beefolives) && is_numeric($beefolives) ? 'Order: beefolives
'.$beefolives : null)
However, for readability and ease of management, you might want to
try something like this. It makes at least two assumptions: you're
using a form post, and you understand that it's untested (as I'm just
typing it here into the body of this email).
<?php
// If we've posted our order
if (isset($_POST) && is_array($_POST['order'])) {
// Instantiate the $order variable
$order = null;
// Iterate the order quantities
foreach ($_POST['order'] as $k => $v) {
// If the field is set and the amount is a number
if (isset($v) && is_numeric($v)) {
$order .= 'Order: '.$k.': '.$v.PHP_EOL;
}
}
/**
* Note: in your example, you used single (literal)
* quotes and included the variables. That would
* literally print $fname and $lname.
*/
$msg = 'Name: '.$_POST['fname'].' '.$_POST['lname'].PHP_EOL;
$msg .= 'Phone: '.$_POST['phone'].PHP_EOL;
$msg .= 'Email: '.$_POST['email'].PHP_EOL;
$msg .= PHP_EOL;
$msg .= $order;
// And then handle the rest of your processing. Here, we just echo.
echo '<pre>'.PHP_EOL.$msg.'</pre>'.PHP_EOL;
}
?>
