hello;

i 'd like to ask you some questions to make a submit foum which we use in this forum for postting new topic, please.

some question as following;

1) in some forum, the top bar of sign- B I U Setc, are they make by button and using in submit form or something else.

2) If i highlight a sentence in the textarea, and then click on the a buton for the sign of B, and then the sign of ['B'] and [/'B'] will come out, and the sentence will sit between then automaticaly.

how can i do that?

do i need a action listener to listen whether i highline a senetnce? and how can the two signs suddenly jump up and sit in the right, position?

3) before i display these masage on the screen, do i need to one word by one word to check whether they have special sign like B I U link etc.
what kind of method can i check it?

Thanks

I would download phpbb and see how they do it, personally I never paid much attention. I would imagine it is javascript.

Thanks lot, please tell me when you understand it.

Maybe you are right, i has not idea what kind of method could help me to reach that in php?

php is server side though, without posting what is in the textarea back to the server php has no idea what is going on. That's why a client side solution such as javascript would be the way to go.
