plzzzzzzz give me a sample code

Have a look at your quotes and commas. There is a mismatch there.

There might also be a problem in that he's inserting a null value. You have no error reporting here at all for the MySQL. mysql_query() will not return a result for an INSERT query, or update query or basically anything that doesn't expect a result from the table. It will, however, return a true or false depending on whether the query was successful or not. To error report correctly, you should change your line to a static call with an 'or die' statement:

mysql_query($query) or die(mysql_error());

The 'or die()' might not be your desired option, but it will kill the code at that point if there's a problem which makes it favourable (for me anyway) for debugging.
