[RESOLVED] $_POST Error

[Nookzor]

I have a form that should allow me to edit photos on a website.

   <input type='file' name='file1' class='picinput'  />
   <input type='file' name='file2' class='picinput'  />

Then i want to manage the files so i thought i should do an if/else loop :

<?
if(isset($_POST['file1'])) {
		move_uploaded_file($_FILES['file1']['tmp_name'], $target1);
						echo "File #1 uploaded";

		              }
							else
					{
					echo "File #1 was not changed.";
					}
?>

It seems like $POST['file1'] is never set ... i tried to print_r($POST['file1']) and it doesn't return anything.
What should i do so my loop will work ?
NOTE : The loop has more statements in it such as declaring variables that later get inserted in the sql db so that's why it's so important.

if(isset($_FILES['file1'])) {
}

And don't forget to add this to your <form> tag...

enctype="multipart/form-data"

enctype="multipart/form-data" was used. the problem was using $POST instead of $FILES.thanks for help

I'm not sure isset($FILES['file1']) is the best condition to check. I think it's set even if file wasn't succesfully uploaded.
From php manual:

if no file is selected for upload in your form, PHP will return $_FILES['userfile']['size'] as 0, and $FILES['userfile']['tmp_name'] as none.

The manual shows an example, where the result of move_uploaded_file is a condition. I usually chack for $FILES['file']['error'] being equal to 0.

wilku , of course it's set even if the file wasn't uploaded.
But i don't check if the file was or wasn't uploaded , i check if there was any user input to that field.
