php + iavascript = rich text contents management

searain

I am looking for a code combine the php and javascript together to let me edit the content that I will send to the database and will be displayed as HTML formatted.

Like this forum Message box. But I want is after I type in the text. Highlight the selected text and then Click B I U, , , will be added, the hightlighted text will be between , , .

Any sample codes you could suggest?

Thanks!

As far as I know, this isn't possible. There's only so much you can do with javascript and a text box, and detecting highlighted text ain't one of them.

Someone correct me if I'm wrong.

Someone give me this link in another post. It is exactly what i was looking for.

I stand corrected. It just occured to me today that Hotmail uses something like that as well. Unfortunately, it can only be used in IE5.5+ but that's not a major problem.
I've been looking over the code, but can't quite figure out how the script figures out which text you have selected. I'm kinda curious as to how it does this.

python_q - when you make the iframe you do this:

function RTFActivate() {
editwindow.document.designMode = "On";
}

which makes it realise that you are using the iframe as a rich text editor, you then use cmdexec for the functions - hence you are limited in what functions you can offer. With RTF editing mode on it behaves just like a normal RTF editor, so the highlighted code/text has html tags placed around it. It just puts <b> at the start of the highlight and </b> at the end for example.

Here is an example of basically the same thing I created about a year ago for asp (would work exactly the same on PHP as its JS)

You cant see it on that one, but you can also swap to designmode.off in the RTF window (iframe) and show innerhtml.on which shows you all the html tags in place. HTH.

Thanks for pointing this out to me. I looked over the code for half an hour and couldn't figure out how they were doing that.

no worries. It puzzled me for a long time.
