Kory, The PHP-db list (and archive) is full of answers to this question. The first example looks a bit suspect unless $field_str holds a set clause in the form: column_name=expression, and further that "expression" does NOT contain double quotes, eg a string value's delimiters. You should precede these with several function calls to 'open' the db, and should follow every mysql_...() call with an error check. Prevailing wisdom suggests putting an echo between the two lines, so that you can see exactly what will be passed as the query to MySQL. Finally, if there is any question, that output can be copied-and-pasted into a command line query or a MySQL administration tool to verify/confirm the SQL syntax.
