[Plugin: Subscribe2] emails have no line breaks. how to add them

    I was using Subscribe2. After an update, the E-mails started getting sent out with no line breaks. Meaning a well formatted blog post was being jumbled up into all 1 line with no spaces between paragraphs.

    To fix this I edited the subscribe2.php code.

    The origonal piece of code looked like this:

    // remove excess white space from with $excerpt and $plaintext
		$excerpt = preg_replace('|\s+|', ' ', $excerpt);
		$plaintext = preg_replace('|\s+|', ' ', $plaintext);
		// prepare mail body texts
		$excerpt_body = str_replace("{POST}", $excerpt, $mailtext);
		$full_body = str_replace("{POST}", strip_tags($plaintext), $mailtext);
		$html_body = str_replace("\r\n", "<br />\r\n", $mailtext);
		$html_body = str_replace("{POST}", $content, $html_body);
		$html_excerpt_body = str_replace("\r\n", "<br />\r\n", $mailtext);
		$html_excerpt_body = str_replace("{POST}", $html_excerpt, $html_excerpt_body);

    I changed it to this:

    // remove excess white space from with $excerpt and $plaintext
		// $excerpt = preg_replace('|\s+|', ' ', $excerpt);
		// $plaintext = preg_replace('|\s+|', ' ', $plaintext);
		// prepare mail body texts
		$excerpt_body = str_replace("{POST}", $excerpt, $mailtext);
		$full_body = str_replace("{POST}", strip_tags($plaintext), $mailtext);
		$html_body = nl2br($mailtext);
		$html_body = str_replace("{POST}", $content, $html_body);
		$html_excerpt_body = nl2br($mailtext);
		$html_excerpt_body = str_replace("{POST}", $html_excerpt, $html_excerpt_body);

    Hope that helps anyone who has the same problem. I spent hours looking for people talking about this, and ended up just editing the code myself.

  • @bartuniek,

    Subscribe2 doesn’t strip HTML tags and replaced them with ignored tags like this. Are you sure you are in the right forum?

    @mattyrob,

    I do not understand your post, so I will try to explain what I was trying to say.

    What I am saying is, that Subscribe2 used to send email notifications with an excerpt from a post that looked correctly in the email client, meaning that all the NewLine characters were correctly interpreted by the email client (I use Outlook for Desktop and RoundCube for Web). Recently, all emails that arrive in my inbox (Outlook and RoundCube) look like one blob of text without any line breaks. Looking inside the emails’ source, I noticed that the underlying HTML has changed as described in my previous post. Upon further investigation, looks like all the emails are sent as HTML

    Content-Type: text/HTML; charset="UTF-8"

    used to be

    Content-Type: text/plain; charset="UTF-8"

    I’ve tried changing settings to force Plain Text for new subscribers, I tried forcing Plain Text for registered WordPress users using Mass Update, nothing works. Next, I’ll try uninstalling Subscribe2 and re-installing it.

    @bartuniek,

    What I’m trying to say, apparently quite poorly, is that the content of the email you pasted above does not look like something Subscribe2 would be doing. It seems the html pre tags have been replaced with the html ignored tags. Subscribe2 does not do that.

    Also, Subscribe2 sends text/plain by default to Public Subscribers, Registered Subscribers can choose their email type.

    DO NOT uninstall or you will lose all of the Subscribe2 plugin settings and subscriber details.

    Uninstalling and re-instaling Subscribe2 didn’t work. So we decided to re-install everything from scratch.

    We have made a new instance of WordPress and installed Subscribe2 and everything WORKS!!! I get Plain Text emails that correctly show line breaks in email excerpts. Examining the email source, we see

    Content-Type: text/plain; charset="UTF-8"

    So the question is, how can we get the old instance to go back to sending just plain text emails? Is there anything we should cleanup manually, since uninstalling didn’t help?

    @bartuniek,

    On the clean install were you using the same theme and all of the same plugins as the affected site? If not, install these individually and see if there is a conflict somewhere.

    On the clean install we used different theme and just the Subscribe2 plugin.

    The problem is that no matter what, all emails go out as HTML. We noticed that also applies to WP password reminders. They arrive as “ContentType = ‘text/HTML’;” whereas before it was plain text.

    So we tried a hack to see what happens and changed the following in the PHPmailer to always send emails as ‘text/plain’:

    //Hack, force text/plain for all emails
public function IsHTML($ishtml = true) {
    if ($ishtml) {
      $this->ContentType = 'text/plain';
    } else {
      $this->ContentType = 'text/plain';
    }
  }

    This hack kinda solved the problem and text emails from Subscribe2 and WP password reminders now arrive as text and are correctly displayed with line breaks. But the problem is still puzzling, why are all emails sent as HTML by PHPmailer?

    Any ides?

    @bartuniek,

    That is probably a conflict coming from your theme or another plugin. I have seen instances of themes and plugins forcing content type to HTML. Not sure why the authors feel the need to apply a global filter to accomplish this for their own ends.
