Are you able to upload the image without using ajax?

[ArshSingh]

No ,,, i have tried in different ways but no success

[jazzman1]

Then, you need to fix first the server side scripting before to proceed to javascript/ajax. 

[ArshSingh]

Im trying but don't know whats wrong

at a starting point turn on error reporting functions.

[ArshSingh]

can u please check if the mysqli_query is okay?

[jazzman1]

You should tell me, I'm not a magic What I want from you is just to provide us all errors coming from your script, then we'll be able to help you effectively.

[ArshSingh]

Okay ,,, i think the error is before mysqli_query ,,, have to check it carefullg

[jazzman1]

When you go to the doctor or to a hospital, is it important you understand what they say to you?

[ArshSingh]

Yup thats right
