NL-PHPMail warning message

LDB · April 28, 2007

Hello!

First off, thanks in advance to anyone who tries/succeeds in helping me out. Appreciate it.

Okay, I'm using NL-PHPMail from Codegrrl.com.

Everything seems to be fine because the form DOES send, however I can never avoid the same away message that always shows up on the page:

Warning: Invalid argument supplied for foreach() in /home/PATH/nlphpmail.php on line 110

(Just so you know, I filled out the correct path)

Here is the entire script exactly as I filled it out:

<?php

//Your email address (where the form will be sent):

$recipient = 'lady.db@gmail.com';

//If you're using PHP headers and footers, please fill in the path to them below. This can be a relative path (like 'header.php' if it's in the same directory), or an absolute path (e.g. '/home/myusername/public_html/myfiles/header.php'. DO _NOT_ USE A URL (e.g. http://site.com/header.inc) - THIS WILL NOT WORK.

//If you're NOT using headers or footers, please leave these empty.

$header_file = '';

$footer_file = '';

/* Change the parts below to the required fields in your form.

If these fields are not filled in, the script will not send an email and will display an error message instead, asking the visitor to fill out the form again.

Here, you should use the EXACT names you have given to the form fields you would like required. For example, if you have this HTML:

...you would write "comment" below (WITH the double quotes). It IS case sensitive, so "Comment" is different to "comment". Check that you are using the same case as in your HTML or you will be unable to send the form.

If you want to add or remove a required field, just copy/delete one of the lines below. */

$alias = $_REQUEST['alias'] ;

$email = $_REQUEST['email'] ;

$site = $_REQUEST['site'] ;

$comments = $_REQUEST['comments'] ;

/* This error message will be displayed if not all required fields are filled in. Feel free to use normal HTML in this, but if you use quotes ( " ) remember to put a backslash ( \ ) in front of them or you will get errors. */

$error_required = "<p>You did not fill some of the required fields in properly. Please go back, refresh the form page, and try again.</p>";

/* This error message will be displayed if the visitor submitted an invalid email address. Feel free to use normal HTML in this - same rules as above apply with the quotes, however. */

$error_email = "<p>It appears that the email address you provided is not valid. Please press the back button on your browser, refresh the form page, and try again.</p>";

/* This success message will be displayed when the form is sent. Feel free to use normal HTML in this, but remember to escape quotes as specified above. */

$success_message = "<p>Your form has been sent! Expect a reply within 1-2 weeks unless otherwise noted.</p>";
