Custom Password Reset Functionality In WordPress

Here we learn about custom password reset functionality with form for WordPress.

1. Create a new template ‘password reset’ into your child theme’s folder.

2. Copy and Paste below code into the ‘password reset’ Template file.

<?php
/*
Template Name: Password Reset Template
*/
global $wpdb, $user_ID;

function tg_validate_url() {
    global $post;
    $page_url = esc_url( get_permalink( $post->ID ));
    $urlget	  = strpos( $page_url, "?" );
    if ($urlget === false) {
        $concate = "?";
    } else {
        $concate = "&";
    }
    return $page_url.$concate;
}

if ( !$user_ID ) { //block logged in users
    if(isset( $_POST['action']) && $_POST['action']=='save_pw_reset' ){
    if ( !wp_verify_nonce( $_POST['save_pwd_nonce'], "save_reset_password" ) ) {
      exit("No trick please");
    }
        $user_login = base64_decode( $_POST['user_token'] );
        $user_data  = $wpdb->get_row( "SELECT ID, user_login, user_email FROM $wpdb->users WHERE ID = '". $user_login ."'" );
        if( $user_data )
        {
            wp_set_password( $_POST['new_password'], $user_login );
            $wpdb->update( $wpdb->users,array('user_activation_key'=>'' ), array( 'ID'=>$user_login ) );
            echo json_encode( array( 'status' => 'success', 'msg' => 'Password Reset successfully' ) );
        }else{
            echo json_encode( array( 'status' => 'error', 'msg' => 'please try again' ) );
        }
        exit();
    }

    if(isset( $_GET['key'] ) && $_GET['action'] == "reset_pwd" ) {
        $reset_key  = $_GET['key'];
        $user_login = base64_decode($_GET['login']);
        $user_data  = $wpdb->get_row( $wpdb->prepare( "SELECT ID, user_login, user_email FROM $wpdb->users WHERE user_activation_key = %s AND (user_login = %s OR user_email = %s )" , $reset_key, $user_login,$user_login ));
