Codeigniter 4 Email sending with HTML as message - php

Question

can you help me figure out a way to use the email class of CI4 to send an email with an HTML as the message?
in Codeigniter 3 it is simple and goes like this:
$email->message($this->load->view('html_page_to_send_from_view_folder',$data,true));
but in Codeigniter 4 I tried doing this:
$email->setMessage(echo view('html_page_to_send_from_view_folder',$data,true));
It gives out an error:
syntax error, unexpected echo(T_ECHO), expecting ')'
I also tried putting the view in a variable like so:
$echo_page = echo view('html_page_to_send_from_view_folder',$data,true);
$email->setMessage($echo_page);
but it just throws the same error, I was searching all over the internet and the documentation but couldn't find a way to do this. Help please.
I tried this but got no error, and also got no email :'(
$echo_page = view('html_page_to_send_from_view_folder',$data,true);
$email->setMessage($echo_page);

Answer 1

According to this, if you want to use some template as your message body, you should do something like this:
// Using a custom template
$template = view("email-template", []);
$email->setMessage($template);
CodeIgniter 4 documentation states:
setMessage($body)
Parameters: $body (string) – E-mail message body
Returns: CodeIgniter\Email\Email instance (method chaining)
Return type: CodeIgniter\Email\Email
Sets the e-mail message body:
$email->setMessage('This is my message');

Okay I got it now I made it work by adding this code $email->setNewLine("\r\n"); at the end just after the setMessage:
$email->setMessage($my_message);
$email->setNewLine("\r\n");
and also I set the SMTP port 587 instead of 465:
$config['SMTPPort']= 587;
ALSO, for the setMessage, I did it like this:
$my_message = view('html_page_to_send_from_view_folder',["id" => $data['id']]);
$email->setMessage($my_message);
really weird man....

Answer 3

A. Firstly,
Instead of:❌
$echo_page = echo view('html_page_to_send_from_view_folder',$data,true);
Use this:✅
$echo_page = view('html_page_to_send_from_view_folder',$data);
Notice the luck of an echo statement and not passing true as the third argument of the view(...) hepler function.
B. Secondly, to submit HTML-based emails, ensure that you've set the mailType property to html. This can be achieved by using the setMailType() method on the Email instance. I.e:
$email->setMailType('html');
Alternatively, you could set the "mail type" by passing an array of preference values to the email initialize() method. I.e:
public function sendMail(): bool
{
$email = \Config\Services::email();
$email->initialize([
'SMTPHost' => 'smtp.mailtrap.io',
'SMTPPort' => 2525,
'SMTPUser' => '479d7c109ae335',
'SMTPPass' => '0u6f9d18ef3256',
'SMTPCrypto' => 'tls',
'protocol' => 'smtp',
'mailType' => 'html',
'mailPath' => '/usr/sbin/sendmail',
'SMTPAuth' => true,
'fromEmail' => 'from#example.com',
'fromName' => 'DEMO Company Name',
'subject' => 'First Email Test',
]);
$email->setTo('to#example.com');
$email->setMessage(view('blog_view'));
$response = $email->send();
$response ? log_message("error", "Email has been sent") : log_message("error", $email->printDebugger());
return $response;
}
