Trouble with Matt's Column Sorting Tutorial

I am getting the following error when using the tutorial example that Matt provided on how to sort a retrieved table by column headings:

Fatal error: Call to undefined function: mysql_fetch_assoc()

Other functions, such as mysql_fetch_array() work. Is this a version problem, or am I missing something?

Thanks,
Rich

Anyone have a clue to loan as to why the actual data is not displayed?

Thanks

RE: Trouble with Matt's Column Sorting Tutorial

Try changing this line
'<TD>$column</TD>n';
so it would look like this:
'<TD>'.$column'.</TD>n';

RE: Trouble with Matt's Column Sorting Tutorial

Doh! That fixed it. I looked and looked and looked at the code and didn;t see that I had the variable within the ticks....ah well, thanks for the pointer!

On another issue with this code, HOW can I change the column name display? Instead of 'datecon', I would prefer 'Date of Contact'? Also, can I prevent certain columns from being displayed at all? Would this be done from within the select statement?

TIA

RE: Trouble with Matt's Column Sorting Tutorial

Glad that helped. As far as column names, set them in the Select statement, like this:

$query = ("SELECT M.Firm, L.abrev Local, M.memberType Type, M.Name, M.Street, M.City, M.State, M.Zip, M.Phone, M.Ext, M.Fax, M.Email, M.WebURL"); $query .= (" FROM Member M, LocalAssn L");
$query .= (" WHERE M.LocalAssn_id=L.assn_id");

For instance, the word Local is substituted for the L.abrev column name in the results.

RE: Trouble with Matt's Column Sorting Tutorial

If it is in the select statement, it will print, so change your select statement from * (all) to the explicit columns you want returned, as in the previous post example.
