Hey. I'm having some troubles with a php script I got a while ago for form to email on a website i'm currently working on. The client has recently switched to a different hosting server and they require SMTP authentication for the new cloudsites....I have about 5 different pretty detailed forms that i need to have the SMTP authentications placed into, but i have no idea what i'm doing. below is my current coding. i'm just not sure how to place the SMTP into the coding correctly. i've seen that i need to download swift or pear and i have no clue where to start. any help or direction would be greatly appreciated...thanks. the current PHP script for my form to email: <?php $my_email = "studio@roharikproductions.com"; /* Enter the continue link to offer the user after the form is sent. If you do not change this, your visitor will be given a continue link to your homepage. If you do change it, remove the "/" symbol below and replace with the name of the page to link to, eg: "mypage.htm" or "http://www.elsewhere.com/page.htm" */ $continue = "index.html"; /* Step 3: Save this file (FormToEmail.php) and upload it together with your webpage containing the form to your webspace. IMPORTANT - The file name is case sensitive! You must save it exactly as it is named above! Do not put this script in your cgi-bin directory (folder) it may not work from there. THAT'S IT, FINISHED! You do not need to make any changes below this line. */ $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['email']) && !empty($_REQUEST['email'])) { if (empty($_POST['email2']) || $_POST['email2'] != $_POST['email']){$errors[] = "Email addresses do not match.";} if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or a colon";} $_REQUEST['email'] = trim($_REQUEST['email']); if(substr_count($_REQUEST['email'],"@") != 1 || stristr($_REQUEST['email']," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST['email']);if(empty($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['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$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") ?
