[WordPress] Uploading Files to a Custom Directory in WordPress

00-wp-mkdir-p.php

<?php

// First, make sure the directory to which we want to upload exists.
$uploads_dir = trailingslashit( plugin_dir_path( dirname( __FILE__ ) ) ) . 'uploads';
wp_mkdir_p( $uploads_dir );

01-move-uploaded-file.php

<?php 

// Now we'll move the temporary file to this plugin's uploads directory.
$source      = $_FILES['acme-imported-file']['tmp_name'];
$destination = trailingslashit( $uploads_dir ) . $_FILES['acme-imported-file']['name'];

move_uploaded_file( $source, $destination )

 $txtPhoto      = isset($_FILES['txtPhoto']) ? $_FILES['txtPhoto'] : '';

                

              //moving image to the plugin directory
                $source      = $txtPhoto;

                $uploads_dir = trailingslashit( plugin_dir_path( dirname( __FILE__ ) ) ) . 'images';
                wp_mkdir_p( $uploads_dir );

                $destination = trailingslashit( $uploads_dir ) . $txtPhoto;

                move_uploaded_file( $source, $destination );

here is my code as you show, but unfortunately it doesn't work!
