Hmm...either i don´t really get what you mean, or you missed the problem. This is the situation:
I have a form which results is to be inserted in a db. When the form is submitted the page calls itself and does a db INSERT based on if a couple of statements is true - otherwise it displays a proper error message. So far everything is fine and is working like a charm. But: I want a redirection after a successfull db INSERT. After the INSERT is made (which is what the page is for) i set a variable, $done, to 1. Right now i only use $done to display a message at the bottom of the screen saying that the INSERT worked. But i want the page to redirect itself as soon as $done is set to 1. The problem i have is: I can only send headers (wich i use for redirection - right??) at the top of the page - before all the other code. But since $done is set far down in the code, after my form and db-statements, the header will never know when to be sent. Is there a way of calling a headerfunction in the top of the page? - Daniel > -----Original Message----- > From: Christian Dechery [mailto:[EMAIL PROTECTED]] > Sent: den 25 november 2001 18:41 > To: Daniel Alsén; PHP; Miles Thompson > Subject: RE: [PHP] Redirect upon execution of script... > > > sorry if I'm not understanding correctly your problem... but it > seems quite > simple to me... > I've created like 10.000 php forms that does that...
