php form not validatin or sending mails - php

Question

I a trying to fix a php form that doesn't work
I am new to php, please help
I have the form in the index.html file and have another validation.php to validate the form fields.
<!-- contact form --->
<div class="containerq">
<div class="form_container">
<h2 class="text-center">Contact us</h2>
<form action="index.php" method="post" class="rd-mailform">
<input type="hidden" value="contact" name="form-type">
<fieldset>
<div class="row">
<div class="col-md-prefix-1 col-md-12">
<label data-add-placeholder="" class="mfInput">
<input type="text" name="name" placeholder="Name">
</label>
</div>
<div class="col-md-prefix-1 col-md-12">
<label data-add-placeholder="" class="mfInput">
<input type="text" name="email" placeholder="Email">
</label>
</div>
<div class="col-md-prefix-1 col-md-12">
<label data-add-placeholder="" class="mfInput">
<input type="text" name="phone" placeholder="Phone">
</label>
</div>
<div class="col-md-prefix-1 col-md-12">
<label data-add-placeholder="" class="mfSelect">
<select class="opt">
<option>Choose subject</option>
<option>I have a problem with a game</option>
<option>I have a problem with a course</option>
<option>I have an Idea</option>
<option>Collaboration with schools</option>
<option>Collaboration with game developers</option>
<option>General query and other subjects</option>
</select>
<ul class="dropdown">
<li class="option">I have a problem with a game</li>
<li class="option">I have a problem with a course</li>
<li class="option">I have an Idea</li>
<li class="option">Collaboration with schools</li>
<li class="option">Collaboration with game developers</li>
<li class="option">General query and other subjects</li>
</ul><span class="mfPlaceHolder"></span>
</label>
</div>
<div class="col-md-prefix-1 col-md-12">
<label data-add-placeholder="" class="mfInput">
<textarea data-constraints="" name="message" placeholder="Message" class="mtext"></textarea>
</label>
</div>
<!--<input class="header_button" type="submit" name="submit" value="Send Request">-->
<div class="header_button">Send Request </div>
<span class="success"><?php echo $successMessage;?></span>
<div class="mfInfo mfProgress"><span class="cnt"></span><span class="loader"></span><span class="msg"></span></div>
</div>
</fieldset>
</form>
</div>
</div>
in the header (which is in included at the index.php start) I added:
<?php require_once "validation.php";?>
because if I put require_once validation.php at the start of the index the form wouldn't be accessed.
in the validation.php this is the part that sends the mail:
if( !($name=='') && !($email=='') && !($phone=='') &&!($message=='') )
{ // Checking valid email.
if (preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/",$email))
{
$header= $name."<". $email .">";
$headers = "mywebsite.com"; /* Let's prepare the message for the e-mail */
$msg = "Hello! $name Thank you...! For Contacting Us.
Name: $name
E-mail: $email
Phone: $phone
Message: $message
This is a Contact Confirmation mail. We Will contact You as soon as possible.";
$msg1 = " $name Contacted Us. Hereis some information about $name.
Name: $name
E-mail: $email
Phone: $phone
Message: $message "; /* Send the message using mail() function */
if(mail($email, $headers, $msg ) && mail("receiver_mail_id#mywebsite.com", $header, $msg1 ))
{
$successMessage = "Message sent successfully.......";
}
}
else
{
$emailError = "Invalid Email";
}
}
but id doesn't send anything
the page gets reloaded to index.php#
I don't get the invalid email or Message sent successfully messages either
this is the complete validation.php:
<?php // Initialize variables to null.
//echo "validating";
$name =""; // Sender Name
$email =""; // Sender's email ID
$purpose =""; // Subject of mail
$message =""; // Sender's Message
$phone ="";
$nameError ="";
$emailError ="";
$phoneError ="";
$messageError ="";
$successMessage =""; // On submittingform below function will execute.
if(isset($_POST['submit']))
{ // Checking null values in message.
echo "validating2";
if (empty($_POST["name"])){
$nameError = "Name is required";
}
else
{
$name = test_input($_POST["name"]); // check name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name))
{
$nameError = "Only letters and white space allowed";
}
} // Checking null values inthe message.
if (empty($_POST["email"]))
{
$emailError = "Email is required";
}
else
{
$email = test_input($_POST["email"]);
} // Checking null values inmessage.
if (empty($_POST["phone"]))
{
$phoneError = "Phone is required";
}
else
{
$phone = test_input($_POST["phone"]);
} // Checking null values inmessage.
if (empty($_POST["message"]))
{
$messageError = "Message is required";
}
else
{
$message = test_input($_POST["message"]);
} // Checking null values inthe message.
if( !($name=='') && !($email=='') && !($phone=='') &&!($message=='') )
{ // Checking valid email.
if (preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/",$email))
{
$header= $name."<". $email .">";
$headers = "mywebsite.com"; /* Let's prepare the message for the e-mail */
$msg = "Hello! $name Thank you...! For Contacting Us.
Name: $name
E-mail: $email
Phone: $phone
Message: $message
This is a Contact Confirmation mail. We Will contact You as soon as possible.";
$msg1 = " $name Contacted Us. Here is some information about $name.
Name: $name
E-mail: $email
Phone: $phone
Message: $message "; /* Send the message using mail() function */
if(mail($email, $headers, $msg ) && mail("contact#mywebsite.com", $header, $msg1 ))
{
$successMessage = "Message sent successfully.......";
}
}
else
{
$emailError = "Invalid Email";
}
}
} // Function for filtering input values.function test_input($data)
// Function for filtering input values.
function test_input($data)
{
$data = trim($data);
$data =stripslashes($data);
$data =htmlspecialchars($data);
return $data;
}
?>
any ideas?
