Prefix a file upload

[zimmo]

I am unusre of the correct syntax for prefixing the following so it includes the category from another field.

 

I need the following:

if(empty($_FILES['file_name']['name'])) 
{ 
$file_name = $old_file_name; 
} 
else 
{ 
$file_name = $_FILES['file_name']['name']; 

 

To be able to have the category value in the file name at the start, so prefixing the actual image file name.

 

ie: $category,$_FILES...

$prefix = "Blar_";
if(empty($_FILES['file_name']['name'])) 
{ 
$file_name = $prefix.$old_file_name; 
} 
else 
{ 
$file_name = $prefix.$_FILES['file_name']['name']; 
}
