using php to redirect after a form

[apw]

Hello

 

I have a php page called potato for.php with 3 different submit buttoms on it

which are called auction, sell and cancel.

 

At the bottom of the page i have this for each of the 3 submit buttoms:

To tell the code what to do after the user selects one of the forrms buttons

 

If (isset($_post["auction"])) {

 

Now that i have this my question is with these how do i redirect the user to

a page like auction.php or to barn.php without using a javascript to do so

 

Thanks

Do all of the PHP parsing at the very top of the page, and then use variables to store the output.

Doing it this way will ensure that you don't get the dreaded "headers already sent" error message, and it will make it a lot easier to write code.

 

Once you've done that, it's just a matter of using following:

header ('Location: new_file.php');
die ();

 

Remember the "die ()" after a redirect, otherwise PHP will continue parsing the script and potentially create problems.

I have the session_start() posted at the very top of the

page where the form is located and when i went to click on

the link i got the cannot modify headers ...

 

The session_start is before any othwr code is even started including

where i tell the script the database name and info.

 

Im not sure now what the problem iis

It probably isn't session_start() causing the error. What does the error message say exactly?

[apw]

The exact error message iis:

 

Warning: cannot send header information - headers already sent by (output startpotato.phped at potato.php:60) in potato.php on line 118.

 

If its refering to line 60 this line has a <?php to start

a new batch of php code

 

Line 118 has this:

header("location: sell.php"); die();

Tip: Look at the name of the function you're using. Should be quite informative when compared to the error message.

Are you displaying anything before the header?

 

Can you give us some code to look at please.

Here is the potatoplant.php that is giving me problems

You've listed the reason yourself, in this post.

 

Also, have you read this thread?
