Hi.
I've written a mailing list form for a website. It currently works by having
the subscriber check up to 3 checkboxes depending on the mailing list they
want to sign up for (prayer, newsletter and announce). They then type their
email address into the "email address" field and click the subscribe button.
After they do that, the php script will check the form for validity and
return error if not filled out the right way or it will send an email to me
if it "worked" (in the sence that the form was filled out by the user the
right way). What I need to know is: given the code below, are there any
examples of php/mysql driven mailing list scripts that I can use as a
tutorial on helping me to convert mine to a mysql database driven program?
Any ideas/recommendations would be apreciated. Thanks for all the help.
The code below if copied and pasted into their own seperate files should
work on any apache/php 5.0.5/mysql 3.xx server.
mailing_list.html:
this file was included in the home page of the website with include().
[code]
<form action="script/mailinglist.php" method="post">
<table border="1" cellspacing="0" cellpadding="2" style="border-color:
#600;">
<tr><th style="background-color: #600; color:#fff; text-align: center;
padding: 0 10px;">Sign up for the mailing lists!</th></tr>
<tr><td>
<input type="checkbox" name="prayer">E Prayer <input type="checkbox"
name="news">E News <input type="checkbox" name="announce">E Announce
</td></tr>
<tr><td style="background-color: #fff; text-align: center; padding: 0
