It says in books etc that I shouldn't use header function after data has been sent to the client. What if I want to forward some info to another webpage after recieveing some of it from the user. How do I do it if I can't do it with the header function? or Can I?
you will have to setup a condition or function to do such, something along these lines:
PHP Code:<?php
if (isset($_REQUEST['url']))
header("Location:".$_REQUEST['url']);
?>
<form method="post" action="?">
<input type="text" name="url" />
<input type="submit" name="submit" value="Go!" />
</form>
you can use the meta tag refresh
<META HTTP-EQUIV="Refresh" Content="5;URL=your site you want to goto.com">
the 5 is how many seconds it will take.
That wont really work for what he wants. :confused:Quote:

actually you are right. headers won't work either

My code does what he asked. He takes information from the client and goes to to it as if it were a web addressQuote:

so does this
PHP Code:<?php
if (isset($_REQUEST['url']))
echo"<META HTTP-EQUIV=\"Refresh\" Content=\"5;URL=".$_REQUEST['url']."\">";
?>
<form method="post" action="?">
<input type="text" name="url" />
<input type="submit" name="submit" value="Go!" />
</form>
Yes, but since he asked for a header function I gave an example of one.Quote:

correct. but he asked what to use if he couldn't use a header function. he will get an error if he sends data to the client and then send the header function. if he doesn't want that error than he can use the meta tag way.
Matt's function works fine. He will not get an error with it and it is much more efficient.Quote:

And he did ask what to do if he couldn't use it, but he also added "or can I?" and that's what Matt was answering. That he could. Which voided the first question.
But I won't argue this thread anymore.
if data has been sent to the client (outputed to the screen) he will get headers already sent error.
that is why my function works better than Matt's.
but whatever.
Exactly where in Matt's example is there data output before the header function?
no where but the question was

Matt's script showed him how to fix that.
Do we have to go round and round?
Sorry for not replying for so long.
Thx for all the help. I finally got it working. :)
