I want post somthing from user just like facebook?

Do you mean you want a post editor on the front-end of the site?

Some member plugins will allow you to do this. For example, Buddypress (plugin) has a member-activity stream, and there are plugins that extend BP with the ability for members to load images, videos, or links to that activity stream.

edit: Didn’t see your reply, James. I took this question to mean just a FB-like stream.

Bill, no worries, I was thinking it could have been that too. ??

Yes i want this

I want front end editor
But How can i do this By plugins or write some code

There are quite a few options to choose from at https://www.ads-software.com/plugins/

Most notably, https://www.ads-software.com/plugins/wp-front-end-editor/ is on track to become a core WordPress feature eventually.

There’s also https://www.ads-software.com/plugins/beaver-builder-lite-version/ which has been getting some nice press recently.
