Taging pictures from facebook API : I think some Array 'Key' Or Json Encode Is the cause

Question

I am trying to post a picture on facebook by the graph API ,How ever I am unable to post that. I get this error

Array ( [error] => Array ( [message] => (#

Answer 1

The problem is x,y coordinate where you want to add tags.

x and y should be as a percentage offset from the left ( for x ) / top ( for y ) edge of the picture i.e.

x and y should be in between 0 - 100.

Facebook Documentation

You can use rand() function

x = rand ( 0, 100 );
y = rand ( 0, 100 );

May be this will help you out. :)
