PHP Page redirect problem - Cannot modify header information [duplicate]
I have much easier solution for you - it is simple! Just add this command at the very start of the php source:
ob_start();This will start buffering the output, so that nothing is really output until the PHP script ends (or until you flush the buffer manually) - and also no headers are sent until that time!So you don't need to reorganize your code, just add this line at the very beginning of your code and that's it :-)
before sending any thing to view (text in the browser). check if your model that if id is valid or not . if id is not valid redirect to your error page
header("HTTP/1.1 301 Moved Permanently");header( 'Location: http://examplesite.domain/errorpage' ) ;
No content should be sent to the browser before using php header() redirection. You can try javascript redirection instead if headers already sent.
if( mysql_num_rows( $qselect ) === 0 ){ echo "<script type='text/javascript'>window.location.href='{http://examplesite.domain/errorpage}'</script>"; exit;}But I am not sure javascript redirects are search engine friendly
