<?php
if (isset($_POST['contact_name']) && isset($_POST['contact_phone']) && isset($_POST['contact_email']) && isset($_POST['contact_text'])){

$contact_name= $_POST['contact_name'];
$contact_phone= $_POST['contact_phone'];

$contact_loc= $_POST['contact_loc'];
$contact_text= $_POST['contact_text'];
foreach($_POST['check'] as $value) {
$check_msg .= "Checked: $value\n";
}
echo"<script> alert($check_msg); </script>;";

if (!empty($contact_name) && !empty($contact_phone) && !empty($contact_email) && !empty($contact_text)){
    $to = 'rameshjoe381@gmail.com';
    $subject = 'Enquiry Form Submitted.';
    $body = "Name: ".$contact_name."\n\n"."Phone No: ".$contact_phone."\n\n"."Message: ".$contact_text."\n\n"."Products: ".$check_msg."\n\n"."Location: ".$contact_loc;
    $headers = 'From: '.$contact_email;
    if (@mail($to, $subject, $body, $headers))
    {?>
        <script type="text/javascript">
    alert("Thanks for contacting us.. We\'ll be in touch soon.'");



  </script><?
  echo "<script>window.location.href='index.html' </script>";

    }
    else{
    alert("Error Sending Mail.");
                                        echo "<script>window.location.href='index.html' </script>";

    }
}else{
    alert("All Fields are required.");
                                        echo "<script>window.location.href='index.html' </script>";

}

}

?>

can you correct the code and spot where i made mistake. thanks for your time in advance

Answer 1

It is important to know the values of a checkbox are only sent when checked. If you need them sent when they are unchecked create a hidden input with the same name right before the checkbox with the value you want sent when not checked.

Answer 2

Change this

$check_msg .= "Checked: $value\n";

To

$check_msg .= "Checked: $value\\n";

Because otherwise in javascript it will throw error, saying string literal is not closed.

Also make the alert like following

echo "<script> alert('$check_msg'); </script>;";
