No way to prevent output of <img> in mail notifications for media attachments

[ginocremer]

Hello Sven, a customer asked us to customize the email notifications. Specifically, there should be no direct tags within the email. Instead, only the URL to the image should be linked (instead of outputting a whole image). The output of the image apparently causes problems in various email clients.

In the file src/db-objects/elements/element-types/base/media.php on line 106 you will find the hardcoded entry with

$output = '<img src="' . $image_url . '" style="max-width:300px;height:auto;" />';

How can we specifically change the output there without having to touch the plugin code?

We got it working by using this code

function pix_filter_attachment_torro( $value, $element ){

        if (strpos($value, '<img') !== false) {
                $doc = new DOMDocument();
                $doc->loadHTML($value);
                $imageTags = $doc->getElementsByTagName('img');

                foreach($imageTags as $tag) {
                    $value = '<a href="'.$tag->getAttribute('src').'">'.$tag->getAttribute('src').'</a>';
                    break;
                }
        }


        return $value;
}
add_filter( 'torro_export_value', 'pix_filter_attachment_torro' , 10, 2 );
