Email PHP script - creating duplicate emails.

[jpopuk]

Hi, I have recently been using a simple enquiry form with some pretty basic PHP.

 

The problem I am getting is when some one submits an enquiry it sends an email as it should but a couple of hours later it is sending a duplicate email. I have contacted my hosts and they say each email has a different ID so it must be within the script.

 

Below is the code, if anyone can spot what could be causing this I would be most grateful.

 

<?php

$my_email = "[email protected]";

$continue = "/";

$errors = array();

// Remove $_COOKIE elements from $_REQUEST.

if(count($_COOKIE)){foreach(array_keys($_COOKIE) as $value){unset($_REQUEST[$value]);}}

// 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);

$message = stripslashes($message);

$subject = "General Enquiry";

$subject = stripslashes($subject);

$from_Name = "";

if(isset($_REQUEST['Name']) && !empty($_REQUEST['Name'])){$from_Name = stripslashes($_REQUEST['Name']);}

$headers = "From: {$from_Name} <{$_REQUEST['Email']}>";

mail($my_email,$subject,$message,$headers);

$message = "Thank you for your enquiry. We will be in touch with you as soon as possible.

Regards,

Website Name
http://www.domain.com";

$subject = "General Enquiry";

$headers = "From: Website Name <[email protected]>";

mail($_REQUEST['Email'],$subject,$message,$headers);

?>

 

Many thanks,

is it doing it every time or just sometimes?

 

it could be something as simple as the user going back to the page at a later time and the script being run again accidentally.

It's doing it everytime. I have used it before on my server and it's worked fine. Just seems to be now, I contacted my host and they suggested seeing if I could get some help with the script but I thought it seemed ok.

 

Thanks for the reply.

I couldn't see how that script is causing an email to be resent 4 hours later...unless what micah is saying is the case.  If not, then I would think it would be some sort of issue with your hosting provider and they may be just telling you its your script because they just want to assume that nothing could possibly be wrong with their system.

I'm working on cleaning up your code. is the $_REQUEST a $_GET or $_POST?

[jpopuk]

I am not 100% sure to be honest. I would imagine it to be $_GEt. I am fairly new to PHP and learning a lot pretty quick.

 

My host is Dreamhost which have been fantastic for as long as I've been using them.

 

Cheers for the help guys, much appreciated!

the form, does it say <form method="POST"> or <form method="GET">?

[jpopuk]

It says:

 

<form name="formcheck" action="/email.php" onsubmit="return formCheck(this);">[code]

 

Cheers

ah, so you're using ajax. It could still be either. I prefer to explicitly state in php which method to go against, so if you can look at the javascript function formCheck(), and look at the method, that would be helpful.

[jpopuk]

This is the javascript that I use with this, doesn't have a formCheck() function.

 

function formCheck(formobj){
// Enter name of mandatory fields	
var fieldRequired = Array("Name", "Email", "Enquiry");	
// Enter field description to appear in the dialog box	
var fieldDescription = Array("Name", "Email", "Enquiry");
// dialog message
var alertMsg = "Please complete the following fields:\n";

var l_Msg = alertMsg.length;

for (var i = 0; i < fieldRequired.length; i++){
	var obj = formobj.elements[fieldRequired[i]];
	if (obj){
		switch(obj.type){
		case "select-one":
			if (obj.selectedIndex == -1 || obj.options[obj.selectedIndex].text == ""){
				alertMsg += " - " + fieldDescription[i] + "\n";
			}
			break;
		case "select-multiple":
			if (obj.selectedIndex == -1){
				alertMsg += " - " + fieldDescription[i] + "\n";
			}
			break;
		case "text":
		case "textarea":
			if (obj.value == "" || obj.value == null){
				alertMsg += " - " + fieldDescription[i] + "\n";
			}
			break;
		default:
		}
		if (obj.type == undefined){
			var blnchecked = false;
			for (var j = 0; j < obj.length; j++){
				if (obj[j].checked){
					blnchecked = true;
				}
			}
			if (!blnchecked){
				alertMsg += " - " + fieldDescription[i] + "\n";
			}
		}
	}
}

if (alertMsg.length == l_Msg){
	return true;
}else{
	alert(alertMsg);
	return false;
}
}[code]

Cheers for the help!!

ok, rather than trying to guess, I've decided to try it this way:

<?php
$my_email = "[email protected]";
$continue = "/";
$errors = array();
$method = "_POST"; // <-- If this fails, change to _GET
// Build message.
function build_message($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($$method);
$message = stripslashes($message);
$subject = "General Enquiry";
$subject = stripslashes($subject);
$from_Name = "";
if(isset($$method['Name']) && !empty($$method['Name'])){
$from_Name = stripslashes($$method['Name']);
}
$headers = "From: {$from_Name} <{$$method['Email']}>";
mail($my_email,$subject,$message,$headers);
$message = "Thank you for your enquiry. We will be in touch with you as soon as possible.
Regards,
Website Name
http://www.domain.com";
$subject = "General Enquiry";
$headers = "From: Website Name <[email protected]>";
mail($$method['Email'],$subject,$message,$headers);
?>

follow the instructions listed in the top.  I didn't really change much in your code.  It works fine. I just cleaned it up so it is standards-compliant.

Many thanks, very much appreciated.
