Nezobrazuje se email odesilatele – PHP Contact Form

10. 11. 2012 13:52:55

Dobrý den, mám jeden docela velký problém. Na mém webu mám contact form psaný v PHP. Vše funguje, ale v příchozím emailu se nezobrazuje email odesilatele.

Místo emailu odesilatele se mi zobrazuje jen:

div v html souboru

contact-process.php

<?php
if(isset($_POST) && empty($_POST))
{
	require 'email-validator.php';
	$validator = new EmailAddressValidator();
	
	$errors = array();
	
	$input_name = strip_tags($_POST);
	$input_email = strip_tags($_POST);
	$input_subject = strip_tags($_POST);
	$input_message = strip_tags($_POST);

$required = array('Name field' => 'name', 'Email field' => 'email', 'Message field' => 'message');
	
	foreach($required as $key=>$value)
	{
		if(isset($_POST) && $_POST !== '') 
		{
			continue;
		}
		else {
			$errors[] = "Please insert your message";
		}
	}
	
    if (!$validator->check_email_address($input_email)) {
           $errors[] = 'Please insert your email correctly';
    }
	
	if(empty($errors))
	{		
		if(mail('info-uk@net-world.cz', "Message from $input_name - $input_subject", $input_message, "Od: $input_email"))
		{
			echo 'Thank you - Your email has been sent';
		}
		else 
		{
			echo 'There was problem with sending your email. Please try again.';
		}		
	}
	else 
	{
		echo implode('<br />', $errors);		
	}
}
else
{
	die('You cannot acess this page');
}

To je tím, že ve skutečnosti mail odesílá funkce mail() na hostingu a ne sám odesilatel, podle kódu byl měl být odesilatel uvedený v samotné zprávě. Při "podvržení" odesilatele do hlavičky emailu to třeba Google stejně pozná a bude zobrazovat upozornění, že se může jednat o podvržený email (nebo to tak aspoň bývalo).

Děkuji za odpověď. Vyřešil jsem to změnou "name" na Email a změnou "subject" na Name. S tím že dotyčný musí vyplnit email dvakrát.
