You're so negative, Jason. :) Long answer, Dave, it wouldn't be wise to do this via Javascript. Javascript can be turned off and also varies from browser to browser (like any client-side language/scripting), so this raises an issue of reliability. You may be able to do it if you're working on an intranet where you know that all users have the same browser, have Javascript turned on, and don't have access to turn it off, OR if this is for your own use and you don't want to make it screw up. Otherwise, it might be a nice feature, but you shouldn't rely on it.
If you WERE going to do it, I would have your main form have a hidden input called "Confirm" and set it to a value of 1. Then, have a "Button" (not a submit button) use Javascript to open a new browser/popup window (you can format it to look like a regular Yes/No windows popup box). Have the "Yes" I-want-to-delete-this-record button change its parent window's form and change the "Confirm" input's value to 0 and submit the parent window's form in order to delete the record. Have the No button just close the popup/new window. Now, on the page that actually deletes the record, first check the Confirm variable. If it is set to 0, then you can figure that the Javascript set it to 0, and you can go ahead and delete the record without asking. Otherwise, show a regular HTML screen that asks if you really want to delete this record (no Javascript this time), so you can be covered if Javascript gets turned off. This is by no means a fool-proof method, and you should think carefully through all this before implementing a Javascript solution, but I find that there are better methods with PHP. For instance, you can have 3 checkboxes side-by-side that can act as the "yes-I-really-really-want-to-delete-this-record" safety. PHP can check to see if all 3 checkboxes were checked, and then you can know that the user was intentionally trying to delete that record, and you can go ahead and delete it - no Javascript needed. :) As far as the Javascripting goes, though, I would check out some JS forums for help on how to set up the actual scripting part of the popup box. But, as Jason probably was thinking, Javascript is never a very good thing to use with things that are delicate, fragile, or valuable in any way. It's like hiring an ex-thief to help you move - you can never be SURE that everything's going to be there in the end. - Jonathan -----Original Message----- From: Jason Wong [mailto:[EMAIL PROTECTED]] Sent: Monday, April 01, 2002 12:45 AM To: [EMAIL PROTECTED] Subject: Re: [PHP-DB] Pop up are you sure...
