Debugging is part and parcel of development and especially now applications getting complex with the advent of mobile apps development, developers need to log Form submitted $_POST and $_FILES data. Here’s a useful snippet to log the posted data that you can place in your PHP script to help you identify the problematic part.

Jut create the /logs/ directory along side the file where you include the code:

 
if ( isset($_POST) && is_array($_POST) && count($_POST) > 0 ) {
  $log_dir = dirname( __FILE__ ) . '/logs/';
  $log_name = "posts-" . $_SERVER['REMOTE_ADDR'] . "-" . date("Y-m-d-H") . ".txt";
  $log_entry = gmdate('r') . "\t" . $_SERVER['REQUEST_URI'] . "\r\n" . serialize($_POST) . "\r\n\r\n";
  $fp=fopen( $log_dir . $log_name, 'a' );
  fputs($fp, $log_entry);
  fclose($fp); }
 
if ( isset($_FILES) && is_array($_FILES) && count($_FILES) > 0 ) {
  $log_dir = dirname( __FILE__ ) . '/logs/';
  $log_name = "posts-" . $_SERVER['REMOTE_ADDR'] . "-" . date("Y-m-d-H") . ".txt";
  $log_entry = gmdate('r') . "\t" . $_SERVER['REQUEST_URI'] . "\r\n" . serialize($_FILES) . "\r\n\r\n";
  $fp=fopen( $log_dir . $log_name, 'a' );
  fputs($fp, $log_entry);
  fclose($fp); }

Hope that helps.
