fugix Posted April 30, 2011 Share Posted April 30, 2011 can someone enlighten me as to what is wrong with this snippet $message_sql = "select * from messages where to_id=$id and read='no'"; $message_query = mysql_query($message_sql); $message_num_rows = mysql_num_rows($message_query); i get this error PHP Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given what its basically telling me is that the "read" filed doesnt exist..because when I take it out of my query, the query works fine...however I do have a "read" field in my db with value of "no" stored in it..so im not sure why its telling me that it doesnt exist..

PFMaBiSmAd Posted April 30, 2011 Share Posted April 30, 2011 If you search for that error message, you will find that it generally means that your query failed due to an error of some kind and you would use mysql_error() to find out why.

PFMaBiSmAd Posted April 30, 2011 Share Posted April 30, 2011 Once you use some error checking to find out at what point the query contains an error, you will find that using read as a column name is the problem.
