Simple File Uploader Problem

[ramma03]

Hi once again! 🙂

I'm trying to make a simple file uploader for my site, but i cant get it to work.
the file doesn't copy and the unlink commnad gives me an error.

Here's the code:

<form id="form1" name="form1" method="post" action="upload.php" enctype="multipart/form-data">
    <input type="file" name="archivo" />
  <br />
    <input type="submit" name="btn1" value="Enviar" />
  </p>
  </form>

<?
$dir = "images/";
$filename = $_FILES['archivo']['name'];

if ($_POST['btn1'] == "Enviar")
	{
		copy ($_POST['archivo'], $dir.$filename);
		//echo $archivo."<br>";
		//echo $filename;
		unlink ($archivo);
	}
else
{
}
?>

Thanks a lot!!!!

File uploads are handled by move_uploaded_file()

The first attribute is the temp name of the file stored in the $FILES array in the form $FILES['(name of file upload field goes here - in your case archivo)']['tmp_name']

The second attribute is the file path to where you want it saved (you had this bit right)

if ($_POST['btn1'] == "Enviar")
        {
            move_uploaded_file($_FILES['archivo']['tmp_name'], $dir.$filename);
        } 

No unlink is needed as the file is moved rather than copied from the temp folder to it's final location.

If a file of the same name already exists it will be overwritten. A function you can use to prevent this is available from the page I linked to above.
