<?php

$user = wp_get_current_user();
$userID = $user->ID;

$has_error = false;
$has_success = false;
$message = array();
    
if(isset($_POST['edpr_profile_submit'])){
    if(! isset($_POST['security']) || ! wp_verify_nonce($_POST['security'],'edit-profile-nonce')){
        print('<p">be careful</p>');
    }else{
            
        $firstnameuser = sanitize_text_field($_POST['edpr_firstname']);
        $lastnameuser = sanitize_text_field($_POST['edpr_lastname']);
        
        
        //if( empty($firstnameuser) || empty($lastnameuser) || empty($emailuser) || empty($cellphoneuser) || $genderuser == 'nonete'  ){
        if( empty($firstnameuser) || empty($lastnameuser)  ){
            
            $has_error = true;
            $message[] = "fill all fields";
            
        }
        
        //if(!$has_error) {
        else {
            
            update_user_meta($userID,'first_name',$firstnameuser);
            update_user_meta($userID,'last_name',$lastnameuser);

            //$has_success = true;
            //$message[] = "updated successfully";
            
            $redirecturlll = site_url('/edit-profile/?editprofile=true');
            wp_redirect( $redirecturlll );
            exit;
