Codeigniter 4 使用 HTML 作为消息发送电子邮件

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);

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. Ie:

$email->setMailType('html');

Alternatively, you could set the "mail type" by passing an array of preference values to the email initialize() method. Ie:

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;

}
