Trying to validate a form, suspect that output is being sent before the HTTP headers.

JUMC_Webmaster

This will be the first of two or three scripts that I will be writing to handle form validation. I know my syntax is correct because I am able to get past the PHP to load the HTML code which displays the form. In testing the form by submitting it blank and filling it out with correct information, I get a CGI error stating that output has started before headers were received. The script is below, along with the <HEAD> section of the HTML code.

<?php
//validate the form data submitted
//e-mail it if it all checks out ok

if (isset($HTTP_POST_VARS['Submit']))
{
	$message[] = "The following errors occurred in processing the form<br>";

//check the name
if (eregi ("/^\S+\s+\S+$/", $HTTP_POST_VARS['T1']))
{
	$nameok=TRUE;
}

else
{
	$message[] = "Please enter your name, no numbers or special characters please<br>";
	$nameok=FALSE;
}

//check organization name
if (strlen ($HTTP_POST_VARS['T2']) == 0)
{
	$message[] = "Please enter your organization name<br>";
	$orgok = FALSE;
}

else
{
	$orgok = TRUE;
}

	if (strlen ($HTTP_POST_VARS['T3']) == 0)
{
	$message[] = "Please enter your address<br>";
	$addressok = FALSE;
}

else
{
	$addressok = TRUE;
}

	if (strlen ($HTTP_POST_VARS['T4']) == 0)
{
	$message[] = "Please enter your city<br>";
	$validcity = FALSE;
}

else
{
	$validcity = TRUE;
}

	if (strlen ($HTTP_POST_VARS['T5']) != 2)
{
	$message[] = "Please enter your state<br>";
	$validstate = FALSE;
}

else
{
	$validstate = TRUE;
}

if (eregi ("^[0-9]{5,5}(-[0-9]{4,4})?$", $HTTP_POST_VARS['T6']))
{
	$zipok=TRUE;
}

else
{
	$message[] = "Please enter your zip code. zip+4 is optional.<br>";
	$zipok=FALSE;
}

if (eregi ("^(\()[0-9]{3,3}(\))(\-)[0-9]{3,3}\-[0-9]{4,4}$", $HTTP_POST_VARS['T7']))
{
	$phoneok=TRUE;
}

else
{
	$message[] = "Please enter your phone number with area code<br>";
	$phoneok=FALSE;
}

$newcomments = strip_tags($HTTP_POST_VARS['S1']);

//check as a regular expression.  Verify that a '@' exists, along with at least one '.'
if (eregi ("^([[:alnum:]]|_|\.|-)+@([[:alnum:]]|\.|-)+(\.)([a-z]{2,4})$", $HTTP_POST_VARS['T10']))
{
	$validemail = TRUE;
}

else
{
	$message[] = "Please enter a valid e-mail address.<br>";
	$validemail = FALSE;
}

if ($nameok &&
	$orgok &&
	$addressok &&
	$validcity &&
	$validstate &&
	$zipok &&
	$phoneok &&
	$validemail)
{
	echo "it worked\n";
}

else
{
	echo "<div align=\"left\"><font color=\"ff0000\"><b>";
	foreach ($message as $key => $value)
	{
		echo "$value <br>\n";
	}
}
}
?>

No I am not. All that is happening is that if the file loads, it checks to see if $HTTP_POST_VARS are present. If they are, it proceeds with the form validation, else it will skip all the PHP code and load the HTML that creates the form. I have a much simpler form validation script that works just fine (only validates a few fields). I believe the specific problem is with the regexes. What I want to validate is

a name field that can accept both the first and last name (middle initials and punctuation in the field is optional)
Two fields that I'm checking length is greater than 0
A field that is two characters long
A field that can accept zip codes or zip+4
A field that can accept phone numbers ((xxx) xxx-xxxx or xxx-xxx-xxxx formats)
A field for e-mail addresses (this one should work with the regex that I used since I used it in my other script)
