Fair enough. I work at a church and my boss wanted me to write a
script to send emails to the congregation and have the progress of the
emailing show up in another window. As far as why bother, it's what I
was asked to do. As far as why not output the results in the same
window, I didn't like how it printed the output at the top of the form
and kept pushing the form down. I'm a civil engineer by trade so I'm
sure the code is stupidly written and inefficient so be kind (I'm new
to PHP and javascript). BTW, you're not helping a spammer - this is
for folks who attend our conferences every year and have requested an
HTML brochure rather than a printed brochure.
Anyway - here's the code in order to provide you with detail.
<?php
$email_from = isset($_POST['email_from']) ?
htmlentities($_POST['email_from']) : '';
$email_from_name = isset($_POST['email_from_name']) ?
htmlentities($_POST['email_from_name']) : '';
$email_subject = isset($_POST['email_subject']) ?
htmlentities($_POST['email_subject']) : '';
$email_delay = isset($_POST['email_delay']) ?
htmlentities($_POST['email_delay']) : '';
$errors['cant_open_message'] = "<script type=\"text/javascript\">alert
(\"Can't Open Message File\");</script>";
$errors['cant_open_address'] = "<script type=\"text/javascript\">alert
(\"Can't Open Address File\");</script>";
function showform ($_email_from, $_email_subject, $_address_file,
$_message_file, $_email_delay, $_mime_type) {
