Code for Register

In this code i am validating form and sign up in WordPress on wp action. Add it in functions.php file after above code. If this code will not work then change action wp to init.

<?php
add_action( 'wp', 'cxc_user_register_callback' );

function cxc_user_register_callback() {
	if ( isset( $_POST['formType'] ) && wp_verify_nonce( $_POST['formType'], 'userRegister') ) {

		global $registrationError, $registrationSuccess;

		$u_name = trim( $_POST['user_name'] );
		$u_email = trim( $_POST['user_email'] );
		$u_pwd = trim( $_POST['user_password'] );
		$u_cpwd = trim( $_POST['user_cpassword'] );

		if ( $u_name == '' ) {
			$registrationError .= '<strong>Error! </strong> Enter User name.,';
		}

		if ( username_exists( $u_name ) ) {
			$registrationError .= '<strong>Error! </strong> Username In Use!.,';
		}

		if ( $u_email == '' ) {
			$registrationError .= '<strong>Error! </strong> Enter Email.,';
		}

		if ( $u_pwd == '' || $u_cpwd == '' ) {
			$registrationError .= '<strong>Error! </strong> Enter Password.,';
		}

		if ( strlen( $u_pwd ) < 7) {
			$registrationError .= '<strong>Error! </strong> Use minimum 7 character in password.,';
		}

		if ( $u_pwd != $u_cpwd ) {
			$registrationError .= '<strong>Error! </strong> Password are not matching.,';
		}

		if ( $u_email != '' && !is_email( $u_email ) ) {
			$registrationError .= '<strong>Error! </strong> Invalid e-mail address.,';
		}

		if ( email_exists( $u_email ) != false ) {
			$registrationError .= '<strong>Error! </strong> This Email is already registered.,';
		}

		$registrationError = trim( $registrationError, ',' );
		$registrationError = str_replace( ",", "<br/>", $registrationError );

		if ( empty( $registrationError ) ) {

			$user_login = $u_name;
			$user_email = $u_email;

			$userdata = array(
				'user_login' => $user_login,
				'user_pass' => $u_pwd,
				'user_email' => $user_email
			);

			$user_id = wp_insert_user( $userdata );

			if ( is_wp_error( $user ) ) {
				$registrationError = $user->get_error_message();
			} else {
				$registrationSuccess = '<strong>Success! </strong> Application submitted. Please wait for user approval.';	
				$user = get_userdata( $user_id );						
				wp_set_current_user( $user->ID );
				wp_set_auth_cookie( $user->ID );
				do_action( 'wp_login', $user->user_login, $user );
				wp_redirect( site_url() );
				exit;
