I'm using phpmailer to send mail through smtp.google.com server but now it's not working because they say to use OAuth2.0 configuration.
I referred to some examples and created a sample page using Send Email Using PhpMailer and Gmail XOAUTH2 to test it, but it doesn't work. Can anyone point out what's wrong in the code?
This is my html page
<?php namespace Phppot; require_once ("lib/MailService.php"); $mailService = new MailService(); if (! empty($_POST['send'])) { $response = $mailService->sendContactMail($_POST); } ?> <html> <head> <title>Contact Us Form</title> <link rel="stylesheet" type="text/css" href="assets/css/style.css" /> </head> <body> <div class="form-container"> <form name="frmContact" id="" frmContact"" method="post" action="" enctype="multipart/form-data" onsubmit="return validateContactForm()"> <div class="input-row"> <label style="padding-top: 20px;">Name</label> <span id="userName-info" class="info"></span><br /> <input type="text" class="input-field" name="userName" id="userName" /> </div> <div class="input-row"> <label>Email</label> <span id="userEmail-info" class="info"></span><br /> <input type="text" class="input-field" name="userEmail" id="userEmail" /> </div> <div class="input-row"> <label>Subject</label> <span id="subject-info" class="info"></span><br /> <input type="text" class="input-field" name="subject" id="subject" /> </div> <div class="input-row"> <label>Message</label> <span id="userMessage-info" class="info"></span><br /> <textarea name="content" id="content" class="input-field" cols="60" rows="6"></textarea> </div> <div> <input type="submit" name="send" class="btn-submit" value="Send" /> <div id="statusMessage"> <?php if (! empty($response)) { ?> <p class='<?php echo $response['type']; ?>Message'><?php echo $response['text']; ?></p> <?php } ?> </div> </div> </form> </div> <script type="text/javascript" src="assets/js/validation.js"></script> </body> </html>
This is get_oauth_token.php

You have a namespace problem. You are doing this:
namespace Phppot; use Phppot\Config; use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\Exception;
Then use this:
$mail->SMTPDebug = SMTP::DEBUG_OFF;
Because you have not imported the SMTP class name from the PHPMailer package into your namespace, it will look for a class named Phppot\SMTP
, which does not exist, hence the error message . You can solve this problem by adding the following:
use PHPMailer\PHPMailer\SMTP;
This will make it use the correct SMTP classes from PHPMailer.
Please note that there may be another problem here. You have use Phppot\Config;
, but you are already in the Phppot
namespace, so you will be looking for something named Phppot\Phppot\Config< 的类/code>, which may not exist. If the class is already in the namespace you declared, you don't need to use a
use
statement for it.
