How to Auto Login After Registration in WordPress with core php

Question

I've been trying for days now to take users who have just registered to my WordPress site and automatically log them in and then redirect them to a URL of my choice.

By default, WordPress sends you a username and a password, then you must log in manually. This is a total pain. How can i overcome this.

I have my own registration page(core php page) which successfully adds users into DB. But the point is, i should avoid users to login again.

Once registration is done, it should automatically redirects to home page or profile page.

I am a newbie to wordpress functionalities. It would be grateful if someone(who have knowledge on core functionality of wordpress) at least suggests a way/solution.

Looking forward.
Thanks

// Add on function.php for Auto login after register and redirect to a home page. varified this code

function auto_login_new_user( $user_id ) {
    wp_set_current_user($user_id);
    wp_set_auth_cookie($user_id);
    $user = get_user_by( 'id', $user_id );
    do_action( 'wp_login', $user->user_login );//`[Codex Ref.][1]
    wp_redirect( home_url() ); // You can change home_url() to the specific URL,such as "wp_redirect( 'http://www.wpcoke.com' )";
    exit;
}
add_action( 'user_register', 'auto_login_new_user' );

Hi Patel..Thanks for your code..but i tried to login with sign on function..but it throws an error like **ERROR: The password field is empty** pls check my following code..`$getdetails= mysql_fetch_array(mysql_query("SELECT * FROM `wp_users` WHERE `ID`='$user_id'")); $username=$getdetails['user_login']; $pass=$getdetails['user_pass']; $creds = array(); $creds['user_login'] = $username; $creds['user_pass'] = $pass; $creds['remember'] = true; $user = wp_signon( $creds, false ); if ( is_wp_error($user) ) echo $user->get_error_message(); add_action( 'user_register', 'auto_login_new_user' );` – smallerik Nov 15 '13 at 10:40
this a default wordpress function so not pass any value in function only add on function file. or you can use any plugin for registration? – Ravi Patel Nov 15 '13 at 12:35

Just like the add_action hook below, this stopped sending new WP user notifications. A dangerous function. I had to send my mail from within the function in order to get it sending again. Because it doesn't use the typical "wp_new_user_notification" hook, it was also hard to track down when the bug came up. Unless you have a plan for the mail within this function --- I'd recommend staying away from this one. – Sean Halls Aug 06 '17 at 17:35

Following is based on how WooCommerce creates a new user and logs him in:

$user_pass = esc_attr( $_POST['account_password'] );

$new_user_data = array(
    'user_login' => $_POST['account_username'],
    'user_pass'  => $user_pass,
    'user_email' => $_POST['account_email'],
    'role'       => 'subscriber'
);

$user_id = wp_insert_user( $new_user_data );

// Set the global user object
$current_user = get_user_by( 'id', $user_id );

// set the WP login cookie
$secure_cookie = is_ssl() ? true : false;
wp_set_auth_cookie( $user_id, true, $secure_cookie );

to redirect use wp_safe_redirect, e.g.

wp_safe_redirect( home_url( '/' ) );
exit;

Hi diggy..thanks for the code..but i tried in different way using signon() function..but it throws an error like **ERROR: The password field is empty** though password is generating..i hope its due to cookie problem..pls verify my below code and help me out.._$getdetails= mysql_fetch_array(mysql_query("SELECT * FROM `wp_users` WHERE `ID`='$user_id'")); $username=$getdetails['user_login']; $pass=$getdetails['user_pass']; $creds = array(); $creds['user_login'] = $username; $creds['user_pass'] = $pass; $creds['remember'] = true; $user = wp_signon( $creds, false ); – smallerik Nov 15 '13 at 10:45

Instead of touching core files... You can use this

$secure_cookie = is_ssl();
$secure_cookie = apply_filters('secure_signon_cookie', $secure_cookie, array());
global $auth_secure_cookie;
$auth_secure_cookie = $secure_cookie;

wp_set_auth_cookie($user_id, true, $secure_cookie);
$user_info = get_userdata($user_id);
do_action('wp_login', $user_info->user_login, $user_info);

The function wp_create_user returns the just created user_id which you can use to create a cookie and log the user in. If you wish, you can redirect the logged in user to the profile or home page.

Thanks for your support guys..i did on my own with the following code..thanks for your time and support :)

<i>$getdetails= mysql_fetch_array(mysql_query("SELECT * FROM `wp_users` WHERE `ID`='$user_id'"));
$username=$getdetails['user_login'];


$creds = array();
$creds['user_login'] = $username;
$creds['user_password'] = $password;
$creds['remember'] = true;

    $user = wp_signon( $creds, false );
    if ( is_wp_error($user) ){
        echo $user->get_error_message();
    }else{
        wp_redirect( home_url() );
    }
