I''ll take this one ... all I usually do here is ask questions. The answer to your question is No. Php is run on the *server before* the page is displayed. Therefore, Php cannot popup an alert like JavaScript (which runs on the *client computer after* the page is loaded). That said; if you want to implement a two step procedure like (1) Delete this file. (2) Are you Sure (Y or N)? You can do that with Php, but clicking on (1) must create a request to the server to display a new page with (2) as a form or hyperlinks. Clicking on Y or N must return to the server again in able to perform the action. -- ***************************** Chuck Anderson ?

or you can have the php spit out the javascript as part of the page and trigger it from the onclick= in the submit. -david-

But that''s not "triggered in Php" and is simply JavaScript. -- ***************************** Chuck Anderson ? Boulder, CO www.CycleTourist Everyone''s journey should be different, so that we all are enriched in new and endless ways *****************************
