codeigniter displaying logo in mail

Question

I have created an HTML page with inline css and provided logo as inline css background

<div id="logo_image" style='background: url("<?=base_url();?>assets/images/img2.png") no-repeat scroll 0 0 / 150px auto rgba(0, 0, 0, 0);height: 73px;margin: -15px 0 0;position: absolute; width: 160px;'></div>

I have also tried using

<img src="<?=base_url();?>assets/images/img2.png" style="float: left;margin-top: -11px;width: 100px;margin-left:10px;" />

The mail function used is as below

$this->email->clear();
$this->email->set_newline("\r\n");

$this->email->set_mailtype("html");
$this->email->from('example@gmail.com','example');

$this->email->to($user['email']);
$this->email->subject('Thank You');
$this->email->message($this->load->view('emails/register', $name, TRUE));

$name contains some variables to be displayed in the template register.php

Everything works well except for logo not being displayed

PS : i am working on localhost .

Answer 1

the answer is in ur own question. you are sending mail from localhost/ur localmachine. when u send mail with image or imported css or js which are on ur localmachine, gmail or anyother cannot interprete that as a proper url.

so what it does is appends its own url before it like https://ci3.googleusercontent.com/proxy/..some link..#http://localhost/assets/images/img2.png

so ur image will not be displayed until you upload the project on a domain.

Answer 2

Instead of using:

<img src="<?=base_url();?>assets/images/img2.png" style="float: left;margin-top: -11px;width: 100px;margin-left:10px;" />

try using:

<img src="<?php echo base_url();?>assets/images/img2.png" style="float: left;margin-top: -11px;width: 100px;margin-left:10px;" />

I replaced <?= ... ?> with the full php tag <?php ?> .

I know that it causes problems sometimes, so I always use the full tag.
