mrneilrobinson Posted October 19, 2009 Share Posted October 19, 2009 hi there, i am trying to connect to a db, but i am having the following message return: Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/sites/furryfrog.co.uk/public_html/aliens/addemail.php on line 20 Error querying database. when i change mysql_query() to mysqli_query() i recieve the following message Fatal error: Call to undefined function: mysqli_connect() in /home/sites/furryfrog.co.uk/public_html/aliens/addemail.php on line 12 i am using php version 4, as parts of the site are built in the cms expression engine that does not support php5 i dont know what avenue to pursue with fixing this error, mysqli or mysql? i hope this makes sense! merci Quote Link to comment Share on other sites More sharing options...
fenway Posted October 19, 2009 Share Posted October 19, 2009 The first error means your query failed -- use mysql_error() to determine what the problem was. If you'd like our help, show us both the query and the error. Quote Link to comment Share on other sites More sharing options...
