assigning a file directory from dropdown to image upload

[davids_media]

I have this code where I add records:

 

<?php

ini_set('display_errors',1);
error_reporting(-1);

require_once ('./includes/config.inc.php');

require_once (MYSQL);

$add_cat_errors = array();

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
// Check for a name:
if (empty($_POST['product'])) {
	$add_cat_errors['product'] = 'Please enter the name!';
}

// Check for a description:
if (empty($_POST['prod_descr'])) {
	$add_cat_errors['prod_descr'] = 'Please enter the description!';
}

// Check for a category:
if (!isset($_POST['cat']) || !filter_var($_POST['cat'], FILTER_VALIDATE_INT, array('min_range' => 1))) {
	$add_cat_errors['cat'] = 'Please select a category!';
}

// Check for a price:
if (empty($_POST['price']) || !filter_var($_POST['price'], FILTER_VALIDATE_FLOAT) || ($_POST['price'] <= 0)) {
	$add_cat_errors['price'] = 'Please enter a valid price!';
}

// Check for a category:

	$add_cat_errors['directory'] = 'Please select a directory!';
}

// Check for an image:
if (is_uploaded_file ($_FILES['image']['tmp_name']) && ($_FILES['image']['error'] == UPLOAD_ERR_OK)) {

	$file = $_FILES['image'];

	$size = ROUND($file['size']/1024);

	// Validate the file size:
	if ($size > 512) {
		$add_cat_errors['image'] = 'The uploaded file was too large.';
	} 

	// Validate the file type:
	$allowed_mime = array ('image/jpeg', 'image/JPG', 'image/jpg');
	$allowed_extensions = array ('.jpg', 'jpeg');
	$image_info = getimagesize($file['tmp_name']);
	$ext = substr($file['name'], -4);
	if ( (!in_array($file['type'], $allowed_mime)) 
	||   (!in_array($image_info['mime'], $allowed_mime) ) 
	||   (!in_array($ext, $allowed_extensions) ) 
	) {

		//$new_name = $dir . '/' . $new_name;
		$dest =  "../db/images/$new_name";

		// Move the file to its proper folder but add _tmp, just in case:

		//$dest =  "../db/images/$new_name";
		$dirs = array('full_heads', 'human_hair', 'lip_tattoos', 'ponytails', 'synthetic_hair');

		if (move_uploaded_file($file['tmp_name'], $dest)) {

			// Store the data in the session for later use:
			$_SESSION['image']['new_name'] = $new_name;
			$_SESSION['image']['file_name'] = $file['name'];

			// Print a message:

		} else {
			trigger_error('The file could not be moved.');
			unlink ($file['tmp_name']);				
		}

	} // End of array_key_exists() IF.

} elseif (!isset($_SESSION['image'])) { // No current or previous uploaded file.

}

What I want to achieve is this;

 

When a record is being inserted, a user will make a selection from the dropdown box with a list of directories. Then, a user will upload an image. When a image is uploaded and a directory is chosen, I want the image to be assigned to a specific directory from the list so when the record is inserted, that image will be placed in the specific directory. How do I achieve this please?
