why not have one field with 500 delimited values? yes, there are implications client and server side, and I presume you mean 500 email *addresses* and not 500 entire emails. I've seen Netscape start to drag at about 50 form fields, but they were visible, so I dunno how it will affect rendering if they're hidden, but you do require the browser to load up the fields in memory so they're accessible through the DOM. That's why I suggest one field, 500 values. As far as the server side goes, there are limits to the amount of data you can post to a CGI, but for the life of me I can't remember what they are or even if they're configurable. Shit. I'm not helping, am I. <tip> spend 10-15 minutes researching your question. Either you do it, or one of us does it ;) </tip> I'm having a good day, really sgd -- work: http://www.ti3.com/ non: http://thinksafely.org/ > -----Original Message----- > From: Peter Van Dijck [mailto:peter at vardus.com] > > could having say 500 hidden fields in a form break stuff > down? they contain > emails, is there a maximum on data that can be transferred or > something?
