Hello i have implemented a custom avatar upload from front-end in my wordpress theme. It is working. User can add and remove customa avatar. My problem is when user selects to remove his/her custom avatar, it is removing it from avatar meta but the uploaded avatar image files remains in the server. What i want to make is also force delete the image files of avatar from the server. This is the template of user_profile.php;

<?php
global $current_user, $wp_roles;
get_currentuserinfo();

?>
<div class="entry-content entry">
    <?php the_content(); 

      if ( isset($_REQUEST['error']) && $_REQUEST['error'] == 'true' ){ 
          $error = __('The passwords you entered do not match.  Your password was not updated.', 'cosmotheme');
      }elseif( isset($_REQUEST['success']) && $_REQUEST['success'] == 'true' ){
          $success = __('Your profile info was updated.', 'cosmotheme');
      }


      if ( $error ) echo '<p class="error">' . $error . '</p>'; 
      if ( isset($success) ) echo '<p class="success">' . $success . '</p>'; 

    ?>


    <?php if ( !is_user_logged_in() ) : ?>
            <p class="warning">
                <?php _e('You must be logged in to edit your profile.', 'cosmotheme'); ?>
            </p><!-- .warning -->
    <?php else : ?>

        ?>

$custom_avatar_url = '';    
$custom_avatar_meta =  get_user_meta($current_user->id, 'custom_avatar', true);

And this is the user_profile_update.php;

<?php

global $current_user, $wp_roles;

//require_once( ABSPATH . WPINC . '/registration.php' );

/* If profile was saved, update profile. */
if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'update-user' && ( !defined('IS_FOR_DEMO' ) || get_the_author_meta( 'user_login', $current_user->id ) != 'demo') ) {

    /* Update user password. */
    if ( !empty($_POST['pass1'] ) && !empty( $_POST['pass2'] ) ) { 
        if ( $_POST['pass1'] == $_POST['pass2'] ){
            wp_update_user( array( 'ID' => $current_user->id, 'user_pass' => esc_attr( $_POST['pass1'] ) ) );
        }else{
            $error = __('The passwords you entered do not match.  Your password was not updated.', 'cosmotheme');
        }
    }

    /* Update user information. */
    if ( !empty( $_POST['url'] ) )
        update_user_meta( $current_user->id, 'user_url', esc_url( $_POST['url'] ) );
    if ( !empty( $_POST['email'] ) )
        update_user_meta( $current_user->id, 'user_email', esc_attr( $_POST['email'] ) );
    if ( !empty( $_POST['first-name'] ) ) {
         update_user_meta( $current_user->id, 'first_name', esc_attr( $_POST['first-name'] ) ); 
    }
    if ( !empty( $_POST['last-name'] ) )
        update_user_meta($current_user->id, 'last_name', esc_attr( $_POST['last-name'] ) );
    if ( !empty( $_POST['description'] ) )
        update_user_meta( $current_user->id, 'description', esc_attr( $_POST['description'] ) );

    if ( !empty( $_POST['avatar_id'] )  && $_POST['avatar_id'] != get_user_meta($current_user->id, 'custom_avatar', true) && empty( $_POST['remove_avatar'])){ 
        update_user_meta( $current_user->id, 'custom_avatar', esc_attr( $_POST['avatar_id'] ) );
    }elseif( !empty( $_POST['remove_avatar']) && $_POST['remove_avatar'] == 1){
        update_user_meta( $current_user->id, 'custom_avatar', '-1' );
    }
    /* Redirect so the page will show updated info. */
   // if ( !$error ) {
        $redirect_url   = get_permalink();
                if(isset($error) && $error != ''){  
                    $msg        = array( 'error' => "true" );
                }else{  
                    $msg        = array( 'success' => "true" ); 
                }
                $_url    = add_query_arg( $msg , $redirect_url );

        wp_redirect( $_url );
        exit;
   // }
}
?>

As you can see if the user checks the input "remove avatar" i am updating the custom_avatar meta -1 which makes it invisible to show. This is working but as i said before, i also need to force delete the image file from the server. Can you help me? Thanks.

You just need to write a delete avatar function that gets the location of the file and deletes it using the php unlink function.

The following code can be used as an example of how it's done. I use this to delete the old user avatars when a user uploads a new one. It is also used to replace default avatars that were once stored in a custom directory from an old plugin no longer being used.

function avatar_delete( $user_id ) {
            $old_avatars = get_user_meta( $user_id, 'author_avatar', true );
            $auth = get_the_author_meta( 'user_login', $user_id );
            $wp_content = WP_CONTENT_DIR;
            $filename = $wp_content . '/images/authors/' . $auth . '.jpg';
            if ( file_exists( $filename ) ) {

                unlink( $filename );
            }
            else {
                $upload_path = wp_upload_dir();

                if ( is_array( $old_avatars ) ) {
                    foreach ( $old_avatars as $old_avatar ) {
                        $old_avatar_path=str_replace( $upload_path[ 'baseurl' ], $upload_path[ 'basedir' ], $old_avatar );
                        @unlink( $old_avatar_path );
                    }
                }
            }

            delete_user_meta( $user_id, 'author_avatar' );
        }
