Hi all,

I need some help with my code as I've a trouble with sending the emails with images attachments. I'm using Pear Mail library to send the emails so when I send the emails with attachments to gmail, I am unable to see the attached images in my gmail inbox as there is no images show on the bottom of the subject unless when I open on my email so I can see the images attachments. And I am unable to see the images on yahoo when i sent the emails, so I sent a test email on my webmail with the images as attachments and I can see the images on gmail and yahoo with no problem. I think there is a problem with my PHP script that need to be resolve. 

Here is where I am getting the problem with:
        

//attachments
        if (is_array($email_attachments)) {
            foreach ($email_attachments as $attachments) {
                $filename = str_replace('uploads/', '', $attachments);
                $attachment = '';
                $file_path = '';
                $type = '';

                if (strpos($filename, '.png') !== false) {
                    $type .= 'image/png';
                }
    
                // ADD attachment(s)
                $attachment1 .= "--$boundary1\r\n";
                $attachment1 .= "Content-Type: $type; name=\"$filename\"\r\n";
                $attachment1 .= "Content-Transfer-Encoding: base64\r\n";
                $attachment1 .= "Content-Disposition: attachment; filename=\"$filename\"\r\n";
                $attachment1 .= "\r\n\r\n";
                $attachment1 .= $attachment;
                $attachment1 .= "\r\n\r\n";

                $body .= $attachment1;
                $mime->addAttachment($file_path, $type);
            }
        }

 

 

Here is the full code: 

<?php

Do you know why the images wont show up on yahoo and gmail when I send the images as attachment?

I have checked on the image path and i have put the correct image path so it should work fine.

If you can be able to test it for me to find out why the images wont display and if you fix the issue, please let me know what change I need to make so I will try it out.

 

Any advice would be much appreciated.

Thanks in advance.
