New Lines in iCal Feed Descriptions

[Dan Brubaker]

I was hoping to use the eventorganiser_ical_description filter to add a bunch of content to event descriptions in the calendar feed. Is there a way to add line breaks when using this filter without having to modify ical.php?

I noticed that eventorganiser_escape_ical_text() is removing my \n‘s. But there is a note in the code that says:

An intentional formatted text line break MUST only be included in a “TEXT” property value by representing the line break with the character sequence of BACKSLASH (US-ASCII decimal 92), followed by a LATIN SMALL LETTER N (US-ASCII decimal 110) or a LATIN CAPITAL LETTER N (US-ASCII decimal 78), that is “\n” or “\N”.

Unfortunately, that ^ doesn’t make sense to me… Does it mean that somehow I should be able to use \n‘s? How exactly is that done?

Thanks!

eventorganiser_escape_ical_text() doesn’t remove the \n is just escapes the backslash (otherwise it’ll appear as a new line in the feed itself – which you don’t want).

To add new lines:

add_filter('eventorganiser_ical_description', function(){ 
    return 'Line one\n Line two';
});.

Incidentally if you find you need to modify ical.php, copy it to your theme first, so that it’ll survive plug-in updates. The ical.php template is like all the other templates in the plug-in – overridable by the theme.

Well, that is the behavior that I expected, but something still is not working right…is there a bug? I don’t know what I’m missing here.

This…

add_filter('eventorganiser_ical_description', function(){ 
    return 'Line one\n Line two';
});

Outputs this in Apple Calendar’s event descriptions…

Line one\n Line two

Not this…

Line one
Line two

It only works when I comment out $description = eventorganiser_escape_ical_text( $description ); on line 129 in ical.php.

Sorry, try

add_filter('eventorganiser_ical_description', function(){ 
    return "Line one" . PHP_EOL .  "Line two";
});

or using double quotes

add_filter('eventorganiser_ical_description', function(){ 
    return "Line one \n Line two";
});
