check this out... CLICKY

 

Basically headers have to be sent out before anything is printed to screen!

 

 

i cant find the problem still :(,

 

this is the error i get

 

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\messages\compose.php:37) in C:\xampp\htdocs\messages\compose.php on line 130

Look at the error. If you output anything...

echo

print

 

you can'tmodify the header

you have to use header before any of the above functions.

 

 

<br>

<center>

<b><p><a href="../messages/inbox.php">Inbox</a></b>

<b><p><?php print "$pm_count"." of 50 Total | "."$percent"."% full"; ?></p></b>

</center>

<br>

 

 

All that is going out before you attempt to send the header

is there any way i can do this without header errors ?

 

Yes.

 

1: Organise your code so there is no output before attempting to call header.

2: Place your entire script into an output buffer using ob_start and ob_end_flush.

3: Use a meta tag redirect.

 

1 would be my preferred option.
