Frontend post submission form

I have this code to submit posts from wordpres frontend without login.

<?php
/*
Template Name: Post publish form
*/
 ?>
 <?php
 if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) &&       $_POST['action'] == "new_post") {

// Do some minor form validation to make sure there is content
if (isset ($_POST['title'])) {
    $title =  $_POST['title'];
} else {
    echo 'Please enter the wine name';
}
if (isset ($_POST['description'])) {
    $description = $_POST['description'];
} else {
    echo 'Please enter some notes';
}

$tags = $_POST['post_tags'];
$winerating = $_POST['winerating'];

// ADD THE FORM INPUT TO $new_post ARRAY
$new_post = array(
'post_title'    =>  $title,
'post_content'  =>  $description,
'post_category' =>  array($_POST['cat']),  // Usable for custom taxonomies too
'tags_input'    =>  array($tags),
'post_status'   =>  'publish',           // Choose: publish, preview, future, draft, etc.
'post_type' =>  'post',  //'post',page' or use a custom post type if you want to
'winerating'    =>  $winerating
);

//SAVE THE POST
$pid = wp_insert_post($new_post);

         //KEEPS OUR COMMA SEPARATED TAGS AS INDIVIDUAL
wp_set_post_tags($pid, $_POST['post_tags']);

//REDIRECT TO THE NEW POST ON SAVE
wp_redirect( '/publikation/' );

//ADD OUR CUSTOM FIELDS
add_post_meta($pid, 'rating', $winerating, true); 

//INSERT OUR MEDIA ATTACHMENTS
if ($_FILES) {
    foreach ($_FILES as $file => $array) {
    $newupload = insert_attachment($file,$pid);
    // $newupload returns the attachment id of the file that
    // was just uploaded. Do whatever you want with that now.
    }

    } // END THE IF STATEMENT FOR FILES

} // END THE IF STATEMENT THAT STARTED THE WHOLE FORM

//POST THE POST YO
 do_action('wp_insert_post', 'wp_insert_post');
