Ok im a complete noob to PHP. I'm trying to make a contact form. I had it working perfectly before. But now it seems that I have messed sometime up and I dont know what.

I'm using this code:
NOTE: I put the email address to blank@blank.com solely to not display my email address, I am using the correct email address on my site.

php Syntax (Toggle Plain Text) 
  1.  
  2. <?php
  3.  
  4. $my_email = "BLANK@BLANK.com";
  5.  
  6.  
  7. $continue = "/";
  8.  
  9. $errors = array();
  10.  
  11. // Remove $_COOKIE elements from $_REQUEST.
  12.  
  13. if(count($_COOKIE)){foreach(array_keys($_COOKIE) as $value){unset($_REQUEST[$value]);}}
  14.  
  15. // Check all fields for an email header.
  16.  
  17. function recursive_array_check_header($element_value)
  18. {
  19.  
  20. global $set;
  21.  
  22. if(!is_array($element_value)){if(preg_match("/(%0A|%0D|\n+|\r+)(content-type:|to:|cc:|bcc:)/i",$element_value)){$set = 1;}}
  23. else
  24. {
  25.  
  26. foreach($element_value as $value){if($set){break;} if ($value != “Submit”) {recursive_array_check_blank($value);}}
  27.  
  28. }
  29.  
  30. }
  31.  
  32. recursive_array_check_header($_REQUEST);
  33.  
  34. if($set){$errors[] = "You cannot send an email header";}
  35.  
  36. unset($set);
  37.  
  38. // Validate email field.
  39.  
  40. if(isset($_REQUEST['email']) && !empty($_REQUEST['email']))
  41. {
  42.  
  43. if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or a colon";}
  44.  
  45. $_REQUEST['email'] = trim($_REQUEST['email']);
  46.  
  47. 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)){$errors[] = "Email address is invalid"; break;}}}}}}
  48.  
  49. }
  50.  
  51. // Check referrer is from same site.
  52.  
  53. if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$errors[] = "You must enable referrer logging to use the form";}
  54.  
  55. // Check for a blank form.
  56.  
  57. function recursive_array_check_blank($element_value)
  58. {
  59.  
  60. global $set;
  61.  
  62. if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}}
  63. else
  64. {
  65.  
  66. foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value);}
  67.  
  68. }
  69.  
  70. }
  71.  
  72. recursive_array_check_blank($_REQUEST);
  73.  
  74. if(!$set){$errors[] = "You cannot send a blank form";}
  75.  
  76. unset($set);
  77.  
  78. // Display any errors and exit if errors exist.
  79.  
  80. if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;}
  81.  
  82. if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");}
  83.  
  84. // Build message.
  85.  
  86. 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,", ");}
  87.  
  88. $message = build_message($_REQUEST);
  89.  
  90. $message = $message . PHP_EOL.PHP_EOL."-- ".PHP_EOL."";
  91.  
  92. $message = stripslashes($message);
  93.  
  94. $subject = "FormToEmail Comments";
  95.  
  96. $headers = "From: " . $_REQUEST['email'];
  97.  
  98. mail($my_email,$subject,$message,$headers);
  99.  
  100. ?>
  101.  
  102. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

For the love of God, use [code] tags. +, there's way too much code for a contact form. Not going to read it without code tags, though. Too much work.

Thanks, Ok what is happening is that when I try to submit the contact form I am sent to a blank page that says: " " and no email is sent.

I founf that if I comment out ( remove) that part of code that is looking for an email header the email will be sent off fine. However I'm not sure if this is the correct solution to this problem.

Heres the part of code that it seems I'm having trouble with:

php Syntax (Toggle Plain Text) 
  1.  
  2. // Check all fields for an email header.
  3.  
  4. function recursive_array_check_header($element_value)
  5. {
  6.  
  7. global $set;
  8.  
  9. if(!is_array($element_value)){if(preg_match("/(%0A|%0D|\n+|\r+)(content-type:|to:|cc:|bcc:)/i",$element_value)){$set = 1;}}
  10. else
  11. {
  12.  
  13. foreach($element_value as $value){if($set){break;} if ($value != “Submit”) {recursive_array_check_blank($value);}}
  14.  
  15. }
  16.  
  17. }
  18.  
  19.  
  20. recursive_array_check_header($_REQUEST);
  21.  
  22. if($set){$errors[] = "You cannot send an email header";}
  23.  
  24. unset($set);

So is this code important? or can I just remove it? Also why would I all of a sudden start having problems with this, it was working fine before.

thank you,
