Login using email address instead of username v3.8.4

[johnnie198x]

I want my forum to be setup so that users use their email addresses to login instead of username. I did a search on this forum, and this is the closet to what I wanted:
https://vborg.vbsupport.ru/showthread.php?t=96832

This is for v3.5.0 RC3 and login with either username or email, but I have 3.8.4 PL1 and I want login with email only, not username.

I tried:
File: ./includes/functions_login.php
Line: 140
CHANGED if ($vbulletin->userinfo = $vbulletin->db->query_first("SELECT userid, usergroupid, membergroupids, username, password, salt FROM " . TABLE_PREFIX . "user WHERE username = '" . $vbulletin->db->escape_string(htmlspecialchars_uni($username)) . "'"))

TO if ($vbulletin->userinfo = $vbulletin->db->query_first("SELECT userid, usergroupid, membergroupids, username, password, salt FROM " . TABLE_PREFIX . "user WHERE email = '" . $vbulletin->db->escape_string(htmlspecialchars_uni($username)) . "'"))

It didn't seem to work. Can anyone help me with this? Thanks.

You have to replace it in the strike queries as well, I just tried it and it worked for me. There were 3 places I changed it from username = to email =

I have limited IT skills, so can you be more specific? What are 3 places you changed? Thanks.

I did that and was able to login with my email instead of username. Didn't really test it a lot so don't know if it has any other ramifications with the script in other areas.

Dylanblitz,
Thanks so much for helping me. It worked in the forum, but I think further mod is required for ACP and MCP. Here's the error when logging in ACP:
===============================
Database error in vBulletin 3.8.4:

Invalid SQL:

I hope you can help me with this. Thanks a lot.

Actually, I found an easier way. Revert what I told you before

in the includes/function_login.php

Find on Line 135

PHP Code:

function verify_authentication($username, $password, $md5password, $md5password_utf, $cookieuser, $send_cookies)
{
    global $vbulletin; 


After add

PHP Code:

$get_username_query = $vbulletin->db->query_read("SELECT username FROM " . TABLE_PREFIX . "user WHERE email = '" . $vbulletin->db->escape_string(htmlspecialchars_uni($username)) . "'");

    if ($vbulletin->db->num_rows($get_username_query) > 0)
    {
    $get_username_data = $vbulletin->db->fetch_array($get_username_query);
    $username = $get_username_data[username];
    } 


I did that on 3.8.4PL1 on my local system. I was able to login to the forums and ACP.
