wpdb not inserting row into the table - php

Question

i have a form that allows input of name ,email & photo...when i click on submit i want it to insert a row into the posttype called'contact' with the info submitted the by the form and the image as the featured image but it does nothing
my code
<?php
if (isset($_POST['submit'])) {
$yourname=$_POST['yourname'];
$email=$_POST['email'];
$myimage=$_POST['myimage'];
include_once('../../../wp-config.php');
global $wpdb;
$table = 'wp_posts';
$data = array(
post_title=>$yourname,
post_status=>'Published',
post_type=>'contacts',
email=>$email,
featured_image=>$myimage
);
$wpdb->insert( $table, $data);
}
?>
<form action="" method="POST">
Your Name: <input type="text" name="yourname" value=""> <br>
Your Email: <input type="text" name="email" value=""> <br>
Image: <input type="file" name="myimage" id=""><br>
<input type="submit" name="submit" value="submit" />
</form>
is there any way i can check if row is uploaded & echo a message if insert is done and then redirect to a new url after few seconds.

Answer 1

Check if columns passed on $data exists in database or in form don't have method="post" enctype="multipart/form-data", try insert this.

Answer 2

You can not get the value of uploaded files from the $_POST variable. For that you need to use $_FILES variable.
To make that code work first you have to add following :
In the form tag you need to add method="post" enctype="multipart/form-data".
In the the PHP script where you get the value of image, Use this code to get the value of image.
featured_image => $_FILES['myimage']['name']
