need help validating forms

[chandni]

hello there,
I have been able to create a feed back form which allows me to submit the values from the form to my email address...now i am trying to validate the fields for which i have written a php...but i have a few concerns..for example....if the person enters his name to be empty i am tryng to open a new html page in which all the fields of the earlier feedback form are displayed along with which it displas a messag to enter an emial id...in the process the rest of the values entered should not go to my email its only when the validation for all the fields is done the values go to my email address..in the meantime every field needs to be validated and any of the mandatory fields left empty it should display a new window giving the message to enter vallues in that particular field..i have written the php but i dont know where do i insert this php code...many thanks
chandni

Look at http://www.vodahost.com/vodatalk/for...html#post26480

It does what you want without opening new windows. I think that you have also tested my form, so you have seen how it works.

here copy of php I use alot, you will need to change the "FTG" to the name of your boxes on your form. This script will check box to make sure they are filled in and the email address is vaild etc.

If you need any help the above code just let me know.

you can see it working at www.bluevodaexchangelink.com/contact/contact.php

Re: need help validating forms

I am not sure that this is the right place fo rmy message. i am a newbie, having just created a small business website using Vodablue and Vodahost. I have created a simple sign-in form requesting visitor name and email. The submit button takes them to a resource page where they can download articles and documents. I used the php script at the bottom of the form tutorial1.
The problem is that the submit button works whether visitors enter their name and email or not. So the purpose of the form to build a subscriber list is defeated.
How do I validate the two ffields I have created on my form: name and email? I tried improvising on the script by reading some of the posts on this forum and could not make it work. Here is what I did:
<?PHP
$email = $HTTP_POST_VARS[email];
$mailto = "info@askartsolutions.com";
$mailsubj = "Resource Sign In";
$mailhead = "From: $email\n";
reset ($HTTP_POST_VARS);
$mailbody = "Visitor name and email address:\n";
while (list ($key, $val) = each ($HTTP_POST_VARS))
{
$mailbody .= "$key : $val\n";
}
mail($mailto, $mailsubj, $mailbody, $mailhead);
?>

<?php
// Receiving variables from the form
@$name = addslashes($_POST['name']);
@$email = addslashes($_POST['email']);
// Validation for empty fields and email
if (strlen($name) == 0 )
{
header("Location: name_errorpage.html");
exit;
}
if (strlen($email) == 0 )
{
header("Location: email_errorpage.html");
exit;
}
//Sending Email to form owner
$pfw_header = "From: $email\n"
. "Reply-To: $email\n";
$pfw_subject = "Resource Sign In";
$pfw_email_to = "info@askartsolutions.com";
*****($pfw_email_to, $pfw_subject ,$pfw_message ,$pfw_header ) ;
header("Location: articlepage.html");
?>

Like I said, the first php works, but when i added the second php, I messed up and nothing worked. Please take a ook and tell me what I am doing wrong?

Take the validate part of the script above and place in the top of your php script. you will need to eith add an "error" part or an "error" page, there are many differant way to do what you want. if you don't what to to it in php check the script (by view source) www.bluevodaexchangelink.com/contact/contact.php, try sending the form which email and see what happens, if you want this script let me know.

Re: need help validating forms

Thanks Maddog for your help.
I checked your form and it is exactly what I want - to send visitors to an error page if they put invalid emails. I also want to have their names and emails sent to my email address and for them to be directed to my resource page once they enter a valid email on my form.

I tried your suggestion to put the validate part of the script in the top of the php script (see below) and created an error.html page. The sign in works with a valid email; but invalid email sign-ins still go to my resources page. The only new part now is that if somebody clicks the submit button without entering anything at all, I get the following error message:

Warning: Cannot modify header information - headers already sent by (output started at /home/clpqlxhu/public_html/articles.php:7) in /home/clpqlxhu/public_html/articles.php on line 28


Here is my revised script following your advice:

<script language="php">
// Receiving variables from the form
@$name = addslashes($_POST['name']);
@$email = addslashes($_POST['email']);
// Validation for empty fields and email
if (strlen($name) == 0 )
{
header("Location:error.html");
exit;
}
if (strlen($email) == 0 )
{
header("Location:error.html");
exit;
}
//Sending Email to form owner
$pfw_header = "From: $email\n"
. "Reply-To: $email\n";
$pfw_subject = "Resource Sign In";
$pfw_email_to = "info@askartsolutions.com";
*****($pfw_email_to, $pfw_subject ,$pfw_message ,$pfw_header ) ;
header("Location: articles.php");
$email = $HTTP_POST_VARS[email];
$mailto = "info@askartsolutions.com";
$mailsubj = "Sign In Form";
$mailhead = "From: $email\n";
reset ($HTTP_POST_VARS);
$mailbody = "Name and email address from Sign in form:\n";
while (list ($key, $val) = each ($HTTP_POST_VARS)) { $mailbody .= "$key : $val\n"; }
if (!eregi("\n",$HTTP_POST_VARS[email])) { mail($mailto, $mailsubj, $mailbody, $mailhead); }
</script>


I like your form, but I only have two variables (name and email) to be entered. I don't know anything about html programming, so am afraid to tinker. If I can just get the script to do what you have, I would be overjoyed. I have been fiddling with this for a day and half now.
Any help would be deeply appreciated.

Art
