multile checkboxes and multiple select lists pass the values as an array. you need to convert the array to a string, add this code at line 1 to convert the array to a comma seperated list:
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
foreach($_POST as $key => $val) {
if(is_array($_POST[$key])) $_POST[$key] = implode(", ", $_POST[$key]);
}
}
?>
you will also need to change these lines:
$field_services = $_POST['services[]'];
$field_membership = $_POST['membership[]'];
$field_leads = $_POST['leads[]'];
$field_agree = $_POST['agree[]'];
to remove the [] from the element names:
$field_services = $_POST['services'];
$field_membership = $_POST['membership'];
$field_leads = $_POST['leads'];
$field_agree = $_POST['agree'];
the [] needs to be included with the name of the element in the form, but not when referring to it in the POST array.
if you need further assistance, compress a copy of the file into a zip archive and include that with your replay so i can see the entire page code in context.
