Confirmation required on email change

by

I’m just wondering why wordpress doesn’t send confirmation mail every time user change his/her email address.

How do we know that email address is not fake or mistyped?

So can anyone give me some snippet to implement this function?

Update:

Here is the idea.

  1. user changes his/her mail
  2. We send confirmation email.
  3. If the user confirm that email in X days by clicking confirmation link, then the email should be changed. Else we should use existing email.

Method 1

Like SickHippie posted this functionality is native to WordPress but only for a multisite setup so here is the two functions you need to get this to work on a single site setup which are mostly code one for one from the core /wp-admin/user-edit.php file

function custom_send_confirmation_on_profile_email() {
    global $errors, $wpdb;
    $current_user = wp_get_current_user();
    if ( ! is_object($errors) )
        $errors = new WP_Error();

    if ( $current_user->ID != $_POST['user_id'] )
        return false;

    if ( $current_user->user_email != $_POST['email'] ) {
        if ( !is_email( $_POST['email'] ) ) {
            $errors->add( 'user_email', __( "<strong>ERROR</strong>: The e-mail address isn't correct." ), array( 'form-field' => 'email' ) );
            return;
        }

        if ( email_exists( $_POST['email'] ) ) {
            $errors->add( 'user_email', __( "<strong>ERROR</strong>: The e-mail address is already used." ), array( 'form-field' => 'email' ) );
            delete_user_meta( $current_user->ID . '_new_email' );
            return;
        }

        $hash = md5( $_POST['email'] . time() . mt_rand() );
        $new_user_email = array(
            'hash' => $hash,
            'newemail' => $_POST['email']
        );
        update_user_meta( $current_user->ID . '_new_email', $new_user_email );

        $content = apply_filters( 'new_user_email_content', __( "Dear user,

    You recently requested to have the email address on your account changed.
    If this is correct, please click on the following link to change it:
    ###ADMIN_URL###

    You can safely ignore and delete this email if you do not want to
    take this action.

    This email has been sent to ###EMAIL###

    Regards,
    All at ###SITENAME###
    ###SITEURL###" ), $new_user_email );

        $content = str_replace( '###ADMIN_URL###', esc_url( admin_url( 'profile.php?newuseremail='.$hash ) ), $content );
        $content = str_replace( '###EMAIL###', $_POST['email'], $content);
        $content = str_replace( '###SITENAME###', get_site_option( 'site_name' ), $content );
        $content = str_replace( '###SITEURL###', home_url(), $content );

        wp_mail( $_POST['email'], sprintf( __( '[%s] New Email Address' ), get_option( 'blogname' ) ), $content );
        $_POST['email'] = $current_user->user_email;
    }
}
add_action( 'personal_options_update', 'custom_send_confirmation_on_profile_email' );

// Execute confirmed email change. See send_confirmation_on_profile_email().
function verify_email_change(){
    global $errors, $wpdb;
    $current_user = wp_get_current_user();
    if (in_array($GLOBALS['pagenow'], array('profile.php')) && $current_user->ID > 0) {
        if (isset( $_GET[ 'newuseremail' ] ) && $current_user->ID ) {
            $new_email = get_user_meta( $current_user->ID . '_new_email' );
            if ( $new_email[ 'hash' ] == $_GET[ 'newuseremail' ] ) {
                $user->ID = $current_user->ID;
                $user->user_email = esc_html( trim( $new_email[ 'newemail' ] ) );
                if ( $wpdb->get_var( $wpdb->prepare( "SELECT user_login FROM {$wpdb->users} WHERE user_login = %s", $current_user->user_login ) ) )
                    $wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_email = %s WHERE user_login = %s", $user->user_email, $current_user->user_login ) );
                wp_update_user( get_object_vars( $user ) );
                delete_user_meta( $current_user->ID . '_new_email' );
                wp_redirect( add_query_arg( array('updated' => 'true'), self_admin_url( 'profile.php' ) ) );
                die();
            }
        } elseif ( !empty( $_GET['dismiss'] ) && $current_user->ID . '_new_email' == $_GET['dismiss'] ) {
            delete_user_meta( $current_user->ID . '_new_email' );
            wp_redirect( add_query_arg( array('updated' => 'true'), self_admin_url( 'profile.php' ) ) );
            die();
        }
    }
}
add_action('plugins_loaded','verify_email_change');

Method 2

This is a strange ‘feature’. The function is actually available inside WordPress (WordPress.com has it enabled for their managed blog service), but it is restricted to multisite. If you look in /wp-admin/includes/ms.php you’ll find the function that handles this – line 239 send_confirmation_on_profile_email().

Presumably, you could move this function into your functions.php or into a plugin to gain this functionality, possibly with a bit of tweaking to get it to work right. It doesn’t answer the “why”, but neither does the trac ticket on this subject here.

ETA: Looking further into it, there’s a few other functions you may need to duplicate as well – new_user_email_admin_notice() and update_option_new_admin_email() jump out as potentially necessary.

Method 3

Giri’s response didn’t work for me. I had to tweak mine to make it work (WordPress 3.5)

function cleanup_verify_email_change()
{
    global $errors, $wpdb;
    $current_user = wp_get_current_user();

    // don't execute this if they're trying to dismiss a pending email change
    if (in_array($GLOBALS['pagenow'], array('profile.php')) && $current_user->ID > 0 & !isset($_GET["dismiss"])) 
    {
        if (isset( $_POST[ 'email' ] ) && ($current_user->user_email != $_POST['email']) ) 
        {
            $user->ID = $current_user->ID;
            $user->user_email = esc_html( trim( $_POST[ 'email' ] ) );

            if ( $wpdb->get_var( $wpdb->prepare( "SELECT user_login FROM {$wpdb->users} WHERE user_login = %s", $current_user->user_login ) ) ) {
                $wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_email = %s WHERE user_login = %s", $user->user_email, $current_user->user_login ) );
            }

            wp_update_user( get_object_vars( $user ) );

            wp_redirect( add_query_arg( array('updated' => 'true', 'multisite_cleanup' => 'true'), self_admin_url( 'profile.php' ) ) );
            die();
        } 
        elseif ( !empty( $_GET['dismiss'] ) && $current_user->ID . '_new_email' == $_GET['dismiss'] ) 
        {
            delete_user_meta( $current_user->ID . '_new_email' );
            wp_redirect( add_query_arg( array('updated' => 'true', 'multisite_cleanup' => 'true'), self_admin_url( 'profile.php' ) ) );
            die();
        }
    }
}
add_action('plugins_loaded','cleanup_verify_email_change');

Method 4

I’ve tweaked Giri code so that it works on my wordpress (version 4.8.1+)

before:

 update_user_meta( $current_user->ID . '_new_email', $new_user_email );

after:

 update_user_meta( $current_user->ID, '_new_email', $new_user_email );

The comma needs to replace the period.

Also:

$new_email['hash'];
$new_email['newemail'];

became

$new_email[0]['hash'];
$new_email[0]['newemail'];

Therefore:

function custom_send_confirmation_on_profile_email() {
    global $errors, $wpdb;
    $current_user = wp_get_current_user();
    if ( ! is_object($errors) )
        $errors = new WP_Error();

    if ( $current_user->ID != $_POST['user_id'] )
        return false;

    if ( $current_user->user_email != $_POST['email'] ) {
        if ( !is_email( $_POST['email'] ) ) {
            $errors->add( 'user_email', __( "<strong>ERROR</strong>: The e-mail address isn't correct." ), array( 'form-field' => 'email' ) );
            return;
        }

        if ( email_exists( $_POST['email'] ) ) {
            $errors->add( 'user_email', __( "<strong>ERROR</strong>: The e-mail address is already used." ), array( 'form-field' => 'email' ) );
            delete_user_meta( $current_user->ID, '_new_email' );
            return;
        }

        $hash = md5( $_POST['email'] . time() . mt_rand() );
        $new_user_email = array(
            'hash' => $hash,
            'newemail' => $_POST['email']
        );
        update_user_meta( $current_user->ID, '_new_email', $new_user_email );

        $content = apply_filters( 'new_user_email_content', __( "Dear user,

        You recently requested to have the email address on your account changed.
        If this is correct, please click on the following link to change it:

        ###SITEURL###" ), $new_user_email );

        $content = str_replace( '###ADMIN_URL###', esc_url( admin_url( 'profile.php?newuseremail='.$hash ) ), $content );
        $content = str_replace( '###EMAIL###', $_POST['email'], $content);
        $content = str_replace( '###SITENAME###', get_site_option( 'site_name' ), $content );
        $content = str_replace( '###SITEURL###', home_url(), $content );

        wp_mail( $_POST['email'], sprintf( __( '[%s] New Email Address' ), get_option( 'blogname' ) ), $content );
        $_POST['email'] = $current_user->user_email;
    }
}
add_action( 'personal_options_update', 'custom_send_confirmation_on_profile_email' );

// Execute confirmed email change. See send_confirmation_on_profile_email().
function verify_email_change(){
    global $errors, $wpdb;
    $current_user = wp_get_current_user();
    if (in_array($GLOBALS['pagenow'], array('profile.php')) && $current_user->ID > 0) {
        if (isset( $_GET[ 'newuseremail' ] ) && $current_user->ID ) {
            $new_email = get_user_meta( $current_user->ID, '_new_email' );
            if ( $new_email[0]['hash'] == $_GET[ 'newuseremail' ] ) {
                $user->ID = $current_user->ID;
                $user->user_email = esc_html( trim( $new_email[0][ 'newemail' ] ) );
                if ( $wpdb->get_var( $wpdb->prepare( "SELECT user_login FROM {$wpdb->users} WHERE user_login = %s", $current_user->user_login ) ) )
                    $wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_email = %s WHERE user_login = %s", $user->user_email, $current_user->user_login ) );
                wp_update_user( get_object_vars( $user ) );
                delete_user_meta( $current_user->ID, '_new_email' );
                wp_redirect( add_query_arg( array('updated' => 'true'), self_admin_url( 'profile.php' ) ) );

    }
}
add_action('after_setup_theme','verify_email_change');
