Hi, I am new in CI. And I am liking it. But I am still in confused about so many problems. right now I am facing this one problem is that When I write a function in CI Controller Class which returns a value. Now I want to output this returning value in a specific div of my views. When I do not return the data from the function, rather, just simply write echo in the function it shows the data on the top left corner of the screen. What I basically want is just get the function's returning value in a variable and print it in a specific div of mine. Which is pretty simple I know but its giving me huge problem.
