Report Mysql Update Table Set If(What To Do Here?) in General Programming Posted October 18, 2013 Hi Mark, This is something you should do on the PHP level. Why do you want to do this validation of user input with MySQL? Stef I'm not sure? I'm just trying to limit the number of calls to the database and I'm not sure how to do this within PHP. I just thought I could send it all to MySQL and then filter out the empty fields somehow.
