Concatenate search fields

I'm building my web site using php and mysql.  I'm converting an exiting website from ASP/MS ACCESS.  I'm having a problem with a simple select statement that utilises two drop down select boxes and one single keyword box.  The results from the drop down boxes (County and License fields) work well.  The single keyword box, which searches several fileds (Company, Title, Description), produces syntax errors.  This is the code I'm trying to write on the results page:

$query_rsSearch = sprintf("SELECT * FROM projects WHERE County LIKE '%%%s%%' AND License LIKE '%%%s%%' AND Company+','+Title+','+Description+' LIKE '%%%s%%'", $varcounty__rsSearch,$varlicense__rsSearch,$varkeyword__rsSearch);

Any suggestions on how to correct this world be appreciated.

It should be:

$query_rsSearch = sprintf("SELECT * FROM projects WHERE County LIKE '%%%s%%' AND License LIKE '%%%s%%' AND Company+','+Title+','+Description LIKE '%%%s%%'", $varcounty__rsSearch,$varlicense__rsSearch,$varkeyword__rsSearch);

Also, you should be careful of SQL injection and use mysql_escape_string on all data input by the user.

$query_rsSearch = sprintf("SELECT * FROM projects WHERE County LIKE '%%%s%%' AND License LIKE '%%%s%%' AND Company+','+Title+','+Description LIKE '%%%s%%'", mysql_escape_string($varcounty__rsSearch),mysql_escape_string($varlicense__rsSearch),mysql_escape_string($varkeyword__rsSearch));

Good luck.

Thanks for the input.  Good news, the syntax error message has gone but when I enter a keword in the keyword box, it produces no results.  The County and License fields still produce results but the keyword field draws a blank.  Any further suggestions?

Looks correct to me, it all depends on whether you have data matching the criteria. For sure entering more than one keyword in your keyword box won't produce the expected result since you're doing an exact match (not matching for each keyword).
