It's very basic... I was thinking I could use multiple text colours/sizes and add everything from within code, not having to use a textarea. Nothing seems to work if I try something such as:
$rtf->addText("This is the first line, it's a large font");
$rtf->addText("Some more text here, this would be on a new line and in grey.");
Why does this not work? It seems like I can only pass addColour, FontSize etc once?? and I cannot add new lines without having to use the return key within a textarea.
