renaming a file on upload

Hey

I am working on renaming a file on upload

so far I have managed to put the new name infront of the old name

this is my code

$path1= "images/".$logged_in_user."_". $_FILES['ufile']['name'];

move_uploaded_file($_FILES['ufile']['tmp_name'], $path1);

PHP:

how do I rename the file so it is just $logged_in_user

And before you say, then i may over wright old images, good

I want it so users can have only one image, if they upload a new image, it deletes the old one, instead of me having dead images floating about.

Anybody

 

$_FILES['ufile']['name'] =$_FILES['ufile']['$logged_in_user'];

Code (markup):

 

Don't work (or i am doing it wrong)


$path1= "images/".$_FILES['ufile']['name'] =$_FILES['ufile'][$logged_in_user];

move_uploaded_file($HTTP_POST_FILES['ufile']['tmp_name'], $path1);

and I get this
Warning: move_uploaded_file(images/): failed to open stream: Is a directory in /home/bla/public_html/site/folder/upload_picture.php on line 35

Warning: move_uploaded_file(): Unable to move '/tmp/phpTHU0gj' to 'images/' in /home/bla/public_html/site/folder/upload_picture.php on line 35
Your file has been uploaded

 

Use:

$file_ext = substr($_FILES['ufile']['name'], strrpos($_FILES['ufile']['name'], '.')+1); // get the file extension, like .gif, .jpg etc..
$file_name = "images/" . $logged_in_user . '.' . $file_ext;
move_uploaded_file($_FILES['ufile']['tmp_name'], $file_name); 

PHP:

 

Thank you "Important"

That is what i was planning to build (all i needed was a lil more knowledge)
