Elementary question; new to PHP redirect to contact.php instead of mainpage

iamthejoefox · March 9, 2012

Good evening,

I was wondering how I could get this page to redirect to the contact.php page which the form is on rather than the mainpage. Any little nudge I can get would be appreciated. Currently it is redirecting to the home page. I understand this is a rudimentary question, please understand I am new to PHP. My background is in moderate training with Flash AS3.

# represent this code as your own work. If you wish to share

# this code with others, please do so by sharing the

# following URL:

#

# http://www.boutell.com/newfaq/creating/email.html

# OPTIONAL: use Accountable to prefill the user's real name and

# email address. Requires that you install and configure

# Accountable first. If your site has no use for accounts elsewhere

# this isn't worth the trouble.

#

# If you ARE using Accountable, uncomment the "require" line below.

# You will probably have to fix the path to find login.php in the

# appropriate folder.

#

# See: http://www.boutell.com/newfaq/creating/accounts.html

#require "login.php";

#require '/home/boutell/html/tools/accountable/login.php';

# OPTIONAL: use my Captcha system to prevent automated

# abuse of the contact form. You'll need to install and

# configure the captcha code first.

#

# If you DO have my captcha installed, uncomment the "require" line

# below. You will probably have to fix the path to find captcha.php

So are you looking to redirect back to the contact.php page after the form has been submitted? You should checkout the redirect() function in your code. That may give you a hint as to what needs to be changed.
