Hello Bigwebmaster and Everyone,

First off thanks for reading my message. I want to refer you all to the above mentioned where Bigwebmaster helped someone with a contact form HTML file and made adjustments to the code and created a contact.php file to make the form send email. I have a very similar HTML form/code however I tried to follow the same direction and have been stuck with getting blank emails. I was wondering if there was anyone kind enough to look through my HTML code and the contact.php file and help me get this corrected. I haven't attached any code etc in-case you want the whole file/s sent to an email address or whatever.

A very many thanks.

James

Go ahead and remove enctype="multipart/form-data" in your HTML code above since you are not having them attach any files. See if that makes any difference in getting anything to work for you.

Also while this wouldn't cause any problems for making the above actually work, you are going to want to add in some sort of sanity checks on the code people enter in you form. If you do not do that you are going to find that spammers can eventually abuse your form to send out spam e-mail to others via your web server without you knowing.

Finally to clarify, you are getting e-mails sent to you right? They are just blank? Do they have subjects or is that blank too?

I am getting emails but the subject of the emails states unknown address. Which is very confusing.

I really want to get this working I know I am close to getting it working. I really appreciate you helping me with this.

I was also wondering if you had a little code that maybe I can enter for your suggestion: "you are going to want to add in some sort of sanity checks on the code people enter in you form"

Could you let us know exactly what you receive, you mention that the subject says "Unknown Address". Is this all it says, please let us know exactly what it says word for word. The message part of the e-mail is blank correct?

As far as sanitizing your input, there are many ways. You might take a look at this:

http://www.php.net/manual/en/filter.exa ... dation.php
http://www.php.net/manual/en/function.filter-var.php

So in your above example for the code you posted, you would want to do some sort of validation for each bit of input you receive from your visitor. So take this part of your code:

PHP Code: [ Select ]
$field_email = $_POST['email'];


Instead of that you might do:

PHP Code: [ Select ]
        $field_email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);  
        if (filter_var($email, FILTER_VALIDATE_EMAIL)) {  
            echo "$email is a valid email address.";  
        } else {  
            echo "$email is <strong>NOT</strong> a valid email address.";  
        }
  1.         $field_email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);  
  2.         if (filter_var($email, FILTER_VALIDATE_EMAIL)) {  
  3.             echo "$email is a valid email address.";  
  4.         } else {  
  5.             echo "$email is <strong>NOT</strong> a valid email address.";  
  6.         }


This would first sanitize your input, and then it would validate the e-mail to make sure its actually an e-mail address in a valid format. You can see all of the different types of filters here:

http://www.php.net/manual/en/filter.filters.php

So you can see that the FILTER_SANITIZE_EMAIL removes all characters except letters, digits and !#$%&'*+-/=?^_`{|}~@.[].

yeah sure. Basically when an email arrives I get the 4 labels:

Name
Email
Telephone
Message

thats it. There's no input data. Its like it cant see from where to get the information. However I get how it should and figured with how it was setup it should but nothing always is flawless...lol

btw I added you on twitter today and would like to talk to you about a business interest.

Your code seems correct to me. Do you know what version of PHP is running on your server? Is it a Windows or Linux server?

Feel free to PM me about your business interest.

I would PM you but it seems either I dont have PM rights or its off for everyone. I'll message you on twitter and give you my contact details.

As for PHP on the server its running 5.2.17 linux and I have to say I dont have any kind of issues with the server. This html code is part of a template downloaded from its creator and I'm simply editing it for my own use. (with permission of course, its one of those freebies)

Hey Brian, I made those adjustments but still I'm getting the same thing. An email with the subject "invalid address" and in the email I get just the headings "Name, Email, Telephone and Message" nothing as far as input data on the form.

Man I know we are so close I can feel it....lol Its gotta be something simple tho, I just cant see it

Please let me know what flavor of Linux you are running, ie Redhat, Debian, Ubuntu, etc. Please also let me know what version. Also please let me know what version of PHP you are running as if your version is outdated that could explain some of your problems. What version of Apache are you running? The more information you could tell me about your setup the better I can assist you. By the way, do you have root access to the server, or are you on shared hosting with a hosting company? Thanks!

Brian,

I'm on a shared hosting server. I think what would be easier is if we were in a chat where by I can share my screen with you and then you can see all the information at once.

What do you think of that idea?

Hi James,

I only do help like this via Ozzu as the information we discuss here will hopefully be able to resolve your problem, but also other people down the road as that other thread initially had helped you.

You are absolutely welcome to take screenshots and post them in this thread. You will find an attachment button in the advanced reply area.

Thanks for your understanding :)

If it is in the Outbox, that simply means the other person has not read it yet. If it is in the Sentbox it means it has been read. The system should be working fine :)

The server is with Host Gator on shared hosting. I really wouldn't have thought this server cant handle a simple form to email procedure as it seems to handle a lot more complex scripts, which is why I'm leaning more towards I have something not right with the code either in the contact.php file (previously posted) or my HTML form (again previously posted).

Its gotta be something simple as I get the emails just no end user data in the email.

Most of the problems anybody experience are usually small things that are easily fixable. The problem is determining exactly what that problem is and that is where the more information you can tell me, the better I can diagnose and help you with the problem. For instance the version of PHP you are running is important, if you are running less than PHP 4.1 the $_POST variable isn't even supported yet:

http://php.net/manual/en/reserved.variables.post.php

I imagine your PHP version wouldn't be that old. You might contact your webhost to see if they can help diagnose your problem. Your script looks fine which indicates that it would be the server setup somehow. If you can run this script:

PHP Code: [ Select ]
<?php
phpinfo();
?>
  1. <?php
  2. phpinfo();
  3. ?>


That might tell you more information on how your server is setup, what version of PHP is being used, what functions are disallowed, etc. Some hosts might not let you run the phpinfo() function, not sure what hostgator does.

Brian,

Please see the attached file. Like I said the server handles other configured forms in ready made scripts fine. I appreciate your time and effort on this and will let you know when I have resolved it and what I did.

Thanks.

I looked up your PHP version with others having similar issues. Many mentioned that their rewrite rules were what ended up causing the problem for the $_POST variable being blank.

Could you do me a favor James and look to see if you have a .htaccess file in your root folder. If you do can you please copy and paste the contents of that file here?

Brian,

I got it working.....finally. Sorry but I dont have .htaccess file in root, so thinking whoever is having an issue like I was could maybe have some code wrong like I did....I knew it was coding. I've never had any issues like this before.

I will post how I fixed my issue next. Bare in mind I know one or two of you were looking for this to work with a newsletter and I'm sure this code can be tweaked to fit that as well, however I just wanted the form to be sent via email and I got my result.

Resolution code coming up next

Guys,

attached is a zip file that gives you all that you need to make your form send to email. Please NOTE, this is NOT my work, I dont support any of it and I take NO RESPONSIBILITY for it or how you use it. I recommend you look through the files carefully and you can cut and paste the stuff you need from it to make your own files or use as is.

Good luck everyone and thanks to BigWebmaster for sticking with me.
