He modificado el código Giri para que funcione en mi wordpress (versión 4.8.1+)
antes de:
update_user_meta( $current_user->ID . '_new_email', $new_user_email );
después:
update_user_meta( $current_user->ID, '_new_email', $new_user_email );
La coma necesita reemplazar el punto.
También:
$new_email['hash'];
$new_email['newemail'];
convirtió
$new_email[0]['hash'];
$new_email[0]['newemail'];
Por lo tanto:
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,

If this is correct, please click on the following link to change it:

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

$content = str_replace( '###ADMIN_URL###', esc_url( admin_url( 'profile.php?newuseremail='.$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' ) ) );
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('after_setup_theme','verify_email_change');
Salud.
