Where do I put my link in this php? - php

Question

This is a really trivial question, but I can't figure it out:
I have this php scrip
<?php
// If you want to ignore the uploaded files,
// set $demo_mode to true;
$demo_mode = false;
$upload_dir = 'upload/';
$allowed_ext = array('jpg','jpeg','png','gif');
if(strtolower($_SERVER['REQUEST_METHOD']) != 'post'){
exit_status('Error! Wrong HTTP method!');
}
if(array_key_exists('pic',$_FILES) && $_FILES['pic']['error'] == 0 ){
$pic = $_FILES['pic'];
if(!in_array(get_extension($pic['name']),$allowed_ext)){
exit_status('Only '.implode(',',$allowed_ext).' files are allowed!');
}
if($demo_mode){
// File uploads are ignored. We only log them.
$line = implode(' ', array( date('r'), $_SERVER['REMOTE_ADDR'], $pic['size'], $pic['name']));
file_put_contents('log.txt', $line.PHP_EOL, FILE_APPEND);
exit_status('Uploads are ignored in demo mode.');
}
// Move the uploaded file from the temporary
// directory to the uploads folder:
if(move_uploaded_file($pic['tmp_name'], $upload_dir.'Bild.jpg')){
exit_status('File was uploaded successfuly!');
}
}
exit_status('Something went wrong with your upload!');
// Helper functions
function exit_status($str){
echo json_encode(array('status'=>$str));
exit;
}
function get_extension($file_name){
$ext = explode('.', $file_name);
$ext = array_pop($ext);
return strtolower($ext);
}
?>
After finishing the process, I want to redirect to another page, or even better, directly start another script.
I tried inserting
header('Location: start_conversion.php');
after the last if (File was uploaded sucessfully), but that didn't work.
Where is my mistake?

Answer 1

exit_status appears to terminate your script. So you'd need to put your redirect before that.
Perhaps instead you could use:
function exit_redirect($loc){
header("Location: $loc",TRUE,302);
exit;
}

Answer 2

Ok, the solution was an originally added javascript. I had to redirect from there, then everything worked.
