Wordpress - wp_handle_upload - 如何获取上传文件的文件名/目录？

Question

I am working on a WordPress website which allows users to upload files upon registration. I got the upload and registration portion working. Below is the code that handles the upload once the user clicks the register button:

function text_domain_woo_save_reg_form_fields($customer_id) {
    //First name field
    if (isset($_POST['billing_first_name'])) {
        update_user_meta($customer_id, 'first_name', sanitize_text_field($_POST['billing_first_name']));
        update_user_meta($customer_id, 'billing_first_name', sanitize_text_field($_POST['billing_first_name']));
    }
    //Last name field
    if (isset($_POST['billing_last_name'])) {
        update_user_meta($customer_id, 'last_name', sanitize_text_field($_POST['billing_last_name']));
        update_user_meta($customer_id, 'billing_last_name', sanitize_text_field($_POST['billing_last_name']));
    }
            // $target_path = "c:/"; 
        // $target_path = $target_path.basename( $_FILES['image_verification']['name']); 
        // echo " <script>console.log('it hit!!'); </script>";
        // echo " <script>console.log('image upload - success! " . $target_path . "' ); </script>";
        // if(move_uploaded_file($_FILES['image_verification']['tmp_name'], $target_path)) { 
            // echo "File uploaded successfully!";
            // echo " <script>console.log('image upload - success!'); </script>";
            // echo " <script>console.log('image upload - success! " . $target_path . "' ); </script>";
        // } else { 
            // echo "Sorry, file not uploaded, please try again!"; 
            // echo " <script>console.log('image upload - fail!'); </script>";
            // echo " <script>console.log('image upload - success! " . $target_path . "' ); </script>";
        // } 

    if ( ! function_exists( 'wp_handle_upload' ) ) {
        require_once( ABSPATH . 'wp-admin/includes/file.php' );
    }

    $uploadedfile = $_FILES['image_verification'];
    $movefile = wp_handle_upload($uploadedfile, array('test_form' => false));

    if ($movefile && !isset($movefile['error'])) {
        var_dump($movefile);
    } else {
        echo $movefile['error'];
    }

}

The wp_handle_upload moves the file the user uploads into the C:\wamp64\www\wordpress\wp-content\uploads\2018\07\imgname.png directory.

now my concern here is:

if 2 users register and they both upload the file imgname.png, it will rename the second "imgname.png" to "imgname-1.png". This is perfectly fine but I am trying to also store a reference to these images in the database, how would I be able to know if the image got renamed or not?

Do you guys have any suggestions for this?

Example: UserA signing up uploads a file called "test.png", i want to create a record in the db like this:

|UserA|localhost\wordpress\wp-content\uploads\2018\07\test.png.|

Now UserB signing up uploads a file called "test.png", his file will be renamed "test-1.png". Therefore I would need to create a record in the DB for him as the following:

|UserA|localhost\wordpress\wp-content\uploads\2018\07\test-1.png.|

How would I get the directory/image name of the file if the change to "test 1.png" happened after it was uploaded?

Any suggestions?

To access the new file name, you can use the php function basename() and give it the path returned from the wp_handle_upload() function and compare it to the file name that was uploaded.

$movefile = wp_handle_upload($uploadedfile, array('test_form' => false));
$new_filename = basename( $movefile['file'] );
$filename_was_changed = new_filename !== $_FILES['image_verification']['name'];
