947740 Posted April 24, 2008 Share Posted April 24, 2008 You have to connenct to the database to perform a query on your index.php page. EDIT: Arrrgh. You already made the connection in your header.php. I did not realize that.

The Little Guy Posted April 24, 2008 Share Posted April 24, 2008 Try and change this: $db = mysql_connect($dbhost, $dbuser, $dbpassword); to this: $db = mysql_connect($dbhost, $dbuser); and lowercase the word "Localhost" to "localhost" (may be case sensitive) Link to comment https://forums.phpfreaks.com/topic/102748-mysql_fetch_assoc-error/#findComment-526262 Share on other sites More sharing options...
wildteen88 Posted April 24, 2008 Share Posted April 24, 2008 In config.php you are assigning the $dbdatabase variable your database name. However in header.php on this line: mysql_select_db($database, $db); You are using a variable called $database. Change $database to $dbdatabase in header.php Link to comment https://forums.phpfreaks.com/topic/102748-mysql_fetch_assoc-error/#findComment-526324 Share on other sites More sharing options...

wildteen88 Posted April 24, 2008 Share Posted April 24, 2008 blogtastic should be your database and categories should be your table. Make sure you have spelt the table name correctly in your query. You may have misspelt the table name when your created it, but didn't realise it at the time.
