Upload image php -

i'm trying upload image in specific folder, i'm getting nothing, not error message, when click on upload button blank page, , that's it, missing?

 <?php if ((isset($_post["enviado"])) && ($_post["enviado"] == "form2")) {     $nome_arquivo = $_files['userfile']['name'];      move_uploaded_file($_files['userfile']['tmp_name'],  "../legendofgames/documentos/games/".$nome_arquivo); ?>      <script>     opener.document.form2.strimage.value="<?php echo $nome_arquivo; ?>";     self.close();     </script>     <?php     }     else     {?> 

.

<form  method="post" enctype="multipart/form-data" id="form2">  <p> <input name="userfile" type="file" /> </p> <p> <input type="submit" name="button" id="button" value="upload image" /> </p> <input type="hidden" name="enviado" value="form2" /> </form> <?php }?> 

1.turn on error reporting in php.ini file or add line @ first:

<?php error_reporting(e_all); ?> 

2.it seems u have syntax error on line 4: forget close php code ?>

<?php if ((isset($_post["enviado"])) && ($_post["enviado"] == "form2")) { $nome_arquivo = $_files['userfile']['name'];  move_uploaded_file($_files['userfile']['tmp_name'],  "../legendofgames/documentos/games/".$nome_arquivo); ?>   <script> opener.document.form2.strimage.value="<?php echo $nome_arquivo; ?>"; self.close(); </script> <?php } else {?>
