newbies:form upload

I'm newbies in php&tbs,

I'll to upload file using html form :

<input name="x_name" type="file" class="normal" id="x_name2" value="[var.x_name]">

$x_name = $_POST['x_name']  only contains filename without path ...

and
move_uploaded_file($x_name, $uploadfile);
do no thing ?
Help please :)

... I forgot to define my form
                    enctype="multipart/form-data"
But now he tells me :
                    TinyButStrong Error (Merge PHP global variables): Can't merge [var.x_name] because there is no PHP global variable named 'x_name'.

What's wrong ?

Hello,

The message error occurs because when TBS try to merge [var.x_name], the global variable $x_name is not created.
This can be cause you create $x_name after the Show() method, or because $x_name is coded inside a function, so it is not global but local.
