Post your code and check your error log.

My code:

PHP Code:

 
 function mysql_prep( $value ) {
  $new_enough_php = function_exists( "mysql_real_escape_string" );
  if( $new_enough_php ) { 
 
   $value = mysql_real_escape_string( $value );
  } else { 
    $value = addslashes( $value );
  }
  return $value;
 }
 
 if (isset($_POST['sub']) && isset($_POST['hid']) == 1) {
 
   $news_tittle = trim(mysql_prep($_POST['news_title']));
 $news_tittle_en = trim(mysql_prep($_POST['news_tittle_en']));

 $news_part_en = trim(mysql_prep($_POST['news_part_en']));
 $position = mysql_prep($_POST['position'] +1);
 $news_active = $_POST['news_a'];

 $p1 = $_POST['position'];
 $ni = "";

   }
 
 
 if (basename($_FILES['news_file']['name']) == "") {
 
  $nf = "";
  } else {
 
   $nf = basename($_FILES['news_file']['name']);
 }
 $query = "INSERT INTO news (
    news_tittle, news_tittle_en, news_writer, news_writer_en, news_date, news_part, news_part_en, news_image, news_file, news_content, news_content_en, news_clicks, news_clicks_en, news_active, news_type, news_bar, position

 update_position($p1, "news", 1);
 $result = mysql_query($query, $connection);
 
 if ($ni != "") {
  $path = "../photos/$ni";
  if (move_uploaded_file($_FILES['news_image']['tmp_name'], $path)) {
 
 
   } else {
    echo output_message(0, "error");
 
    }
 
  }
 
  ///////////////
 
  $path2 = "../uploads/$nf";
  if ($nf != "") {
  if (move_uploaded_file($_FILES['news_file']['tmp_name'], $path2)) {

 } else {
  echo output_message(0, "error");
  echo "<p>" . mysql_error() . "</p>";
 }
 
 
 
  } 


I don't know where I can find my error log, can you help me?

Thanks in advance.

Ask your system administrator for the error log info.Try to approach the problem systematically. If it's an intermittent problem then something about the data is causing it. Vary your form inputs and see where the problem lies.

Does it happen for all php files? Or is it only for the form submission..?

only when I submit the form, and sometimes it submit successfully with no proplems

If your running linux, Your error log will be:

/var/log/httpd/error.log

On windows, search for error.log and it will be one of them

This is unrelated, but a quick effientcy practice:

Change line:
$new_enough_php = function_exists( "mysql_real_escape_string" );

and add static in front of it
static $new_enough_php = function_exists( "mysql_real_escape_string" );
