This is my login execution script and when i run it, i get this -

 

Fatal error: Cannot use object of type stdClass as array in /home/a8029060/public_html/login-exec.php on line 75

 

Please any help :/

Whatever it is, it's an object. Don't try to use it as an array.

mysql_fetch_field Returns an object containing field information. This function can be used to obtain information about fields in the provided query result.

Use mysql_fetch_assoc, or something that will return an array from your result set.
