gravityview_import_helper_fix_line_breaks()

gravityview_import_helper_fix_line_breaks	(		$postmeta = array(),
			$post_id = 0,
			$post = array()
	)

Fixes broken serialization character counts when new line characters are in the exported XML.

The XML export file includes the line breaks, which are one character when interpreted by PHP ("\n"). For some reason, which I (Zack) cannot understand, the serialized data for the post meta counts both characters when generating the string length calculations.

For example, the following should be exported with a string length of two: an exclamation mark and a new line ("\n") character. But it's stored in the serialized data as length of three:

s:3:"! ";

So this function replaces new line characters ("\n") in the XML and replaces them with two line break characters in order to match the expected number of characters. I chose this route instead of using placeholders like [newline] in case the second part (updating the meta after import) doesn't work. Multiple new lines is a better outcome than modified text.

Replacing one new line with two makes the maybe_unserialize() function happy. I'm happy because we fixed the bug.

Am I thrilled with this solution? No, no I am not.

Does it work? Yes. Yes, it does.
