Smarty

[JPLiggett]

This tpl code writes out a vcalendar ics file, which is missing the CRLF on line 1 in the output file. How can I add the \n\r or " in the template for the CRLF?

BEGIN:VCALENDAR<need CRLF here>
VERSION:2.0
METHOD:REQUEST
PRODID:-//BookedScheduler//NONSGML {$bookedVersion}//EN
{foreach from=$Reservations item=reservation}
BEGIN:VEVENT
CLASS:PUBLIC
CREATED:{formatdate date=$reservation->DateCreated key=ical}
DESCRIPTION:{$reservation->Description|regex_replace:"/\r\n|\n|\r/m":"\n "}
DTSTAMP:{formatdate date=$reservation->DateCreated key=ical}
DTSTART:{formatdate date=$reservation->DateStart key=ical}
DTEND:{formatdate date=$reservation->DateEnd key=ical}
LAST-MODIFIED:{formatdate date=$reservation->LastModified key=ical}
LOCATION:{$reservation->Location}

You say you are losing the actual newline character between the first and second lines? Interesting. But none of the others?

I haven't tried this, but since Smarty can use many PHP functions without prior setup, try:

[JPLiggett]

but the first line now has the CRLF and the validator complains that the CRLF is missing.

BEGIN:VCALENDAR{chr(13)}
VERSION:2.0 {chr(13)}
METHOD:REQUEST {chr(13)}
PRODID:-//BookedScheduler//NONSGML {$bookedVersion}//EN {chr(13)}
{foreach from=$Reservations item=reservation}
BEGIN:VEVENT{chr(13)}
CLASS:PUBLIC {chr(13)}
CREATED:{formatdate date=$reservation->DateCreated key=ical} {chr(13)}
DESCRIPTION:{$reservation->Description|regex_replace:"/\r\n|\n|\r/m":"\n "}

Some specifications want:
CRLF: two bytes - chr(13)chr(10) - Windows DOS
CR only: Macintosh
LF only: Unix and others

A sloppily expressed error message could say CRLF instead of "newline appropriate for your operating system".

A strict, accurate error message, if it says CRLF is missing, then only adding the CR part is still wanting the LF part.

Or, it could be the case that your text editor is using LF as the newline, and so adding just {chr(13)} might be what you are trying to do.

I would use a programmer's text editor that can view the rendered output from after Smarty processing this template as a hex dump. Make sure there is only 0D 0A as newlines.

A programmer's text editor should be able to load a document and not auto-convert newlines to the system's default bytes. Or be able to save the document using specified newlines regardless of the system.
