I am asking this as general question first because I am not sure that what I am trying to do is even possible.
I am using Dreamweaver 8. I have created a php page that accesses a mySQL database to include information from just one record on a form. Through a unique page, a personalized URL, I am asking someone to update the information and send me an email.
this is mail script:
<?php
//specify mail server
ini_set("SMTP","mail.domainname.com");
//specify SMTP number 25 and 8889 are valid SMTP ports
ini_set("smpt_port","25");
$my_email = "subscribe@domainname.com";
$continue = "../thankyou.html";
$errors = array();
// Remove $_COOKIE elements from $_REQUEST.
if(count($_COOKIE)){foreach(array_keys($_COOKIE) as $value){unset($_REQUEST[$value]);}}
// Check all fields for an email header.
function recursive_array_check_header($element_value)
{
global $set;
if(!is_array($element_value)){if(preg_match( "/(%0A|%0D|\n+|\r+)(content-type:|to:|cc:|bcc:)/i",$element_value)){$set = 1;}}
else
{
foreach($element_value as $value){if($set){break;} recursive_array_check_header($value);}
}
}
recursive_array_check_header($_REQUEST);
if($set){$errors[] = "You cannot send an email header";}
unset($set);
// Validate email field.
if(isset($_REQUEST) && !empty($_REQUEST))
{
if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST)){$errors[] = "Email address may not contain a new line or a colon";}
$_REQUEST = trim($_REQUEST);
if(substr_count($_REQUEST,"@") != 1 || stristr($_REQUEST," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST);if(empty($exploded_email[0]) || strlen($exploded_email[0]) > 64 || empty($exploded_email[1])){$errors[] = "Email address is invalid";}else{if(substr_count($exploded_email[1],".") == 0){$errors[] = "Email address is invalid";}else{$exploded_domain = explode(".",$exploded_email[1]);if(in_array("",$exploded_domain)){$errors[] = "Email address is invalid";}else{foreach($exploded_domain as $value){if(strlen($value) > 63 || !preg_match('/^[a-z0-9-]+$/i',$value)){$errors[] = "Email address is invalid"; break;}}}}}}
}
// Check referrer is from same site.
if(!(isset($_SERVER) && !empty($_SERVER) && stristr($_SERVER,$_SERVER))){$errors[] = "You must enable referrer logging to use the form";}
// Check for a blank form.
function recursive_array_check_blank($element_value)
{
global $set;
if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}}
else
{
foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value); }
}
}
recursive_array_check_blank($_REQUEST);
if(!$set){$errors[] = "You cannot send a blank form";}
unset($set);
// Display any errors and exit if errors exist.
if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;}
if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");}
// Build message.
function build_message($request_input){if(!isset($message_output)){$message_output ="";}if(!is_array($request_input)){$message_output = $request_input;}else{foreach($request_input as $key => $value){if(!empty($value)){if(!is_numeric($key)){$message_output .= str_replace("_"," ",ucfirst($key)).": ".build_message($value).PHP_EOL.PHP_EOL;}else{$message_output .= build_message($value).", ";}}}}return rtrim($message_output,", ");}
$message = build_message($_REQUEST);
$message = $message . PHP_EOL.PHP_EOL."-- ".PHP_EOL."";
$message = stripslashes($message);
$subject = "Reply from Website";
$headers = "From: " . $_REQUEST;
mail($my_email,$subject,$message,$headers);
