Can't Get "}else{" Directory Functions To Work Right

Volitics

The script below won't work. If the "/oop/newspictures/" directory is empty then the second part of the "else" function creates a directory and copies the text file "PlaceHolder.txt" in the directory. That part works just fine.

The problem occurs when the directory exists or has been previously created. When the directory and the PlaceHolder.txt file exist or have been created the code snippet below won't print out "That directory already exists" - it simply quits and displays a blank screen in the browser.

I've been grappling with this problem for two or three days. I have tried numerous different techniques and can't get any of them to work.

What I'm wanting to do is, if the directory already exists, to display a notification to the user that the directory already exists - and if the directory does not exist then create the directory.

I would appreciate if anyone could tell me how to write the code snippet so that it will work.

//The variables in the two lines below are taken from above.
$CheckReference = "20030101";
$Admin[Directory] = "/oop/newspictures/$CheckReference";
//--------------
}else{
$File == "/oop/newspictures/$CheckReference/PlaceHolder.txt";
if ($File){
echo "That directory already exists.";
}else{
$DirectoryName ="$Admin[Directory]";
$DirectoryMade = mkdir($DirectoryName, 0777);
$PlaceHolder = "PlaceHolder.txt";
copy($PlaceHolder, "/oop/newspictures/$CheckReference/PlaceHolder.txt");
$UploadPictureForm = "<form> bla bla .. Upload Form bla bla </form>\n";
}
echo $UploadPictureForm;
}
//-------------

Thanks.

haven't finished looking but noticed this:

$CheckReference = "20030101";

is inside the if{}

and is not defined in the else{}

could it be that the because the directory already exists, $CheckReference is not defined and so the script does not know where to go?

also:

instead of
if ($File){
use

if(file_exists($File))
{

Thank you for your help.

What I've done is put a cookie on the previous page. The $CheckReference variable is stored in a cookie.

I just put the $CheckReference = "20030101"; snippet in the first post trying to make things a little bit more clear. But instead I may have made it a little confusing.

I'll try the "file_exists" function. I've tried numerous file functions but have not tried the "file_exists" function.

I've got a copy of the PHP manual on my desktop that I downloaded from the PHP web site.

The "file_exists" function is right there in front of me - I should have been it but I overlooked it.

Thanks again for the help.

It works!

$File = "/oop/newspictures/$CheckReference/PlaceHolder.txt";
	if (file_exists($File)){
	echo "That directory already exists.";
	}else{
	$DirectoryName ="$Admin[Directory]";
	$DirectoryMade = mkdir($DirectoryName, 0777);
	$PlaceHolder = "PlaceHolder.txt";
	copy($PlaceHolder, "/oop/newspictures/$CheckReference/PlaceHolder.txt");
	$UploadPictureForm = "<form> bla bla Upload... </form>\n";
	}
	echo $UploadPictureForm;

Thanks. Volitics
