!file_exists help

Hi guys

im trying to have a file created if not exist, so far i have

PHP Code:


		
			
$ourFileName = "$vbulletin->options['thefilename']";
 if (!file_exists($vbulletin->options['thefilename'] . '$ourFileName'))
{
$filename = '$ourFileName';
}

i have also tried

PHP Code:


		
			
if (!file_exists($ourFileName)) {
$ourFileName = "$vbulletin->options['thefile']";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}

they work in some ways but not 100%, im not even sure if its the correct format for vbulletin

i know this is not 100% correct but need the variable corrected

What does this mean? Explain in more details how it works/fails.

I think this should work:

Code:

$ourFileName = $vbulletin->options['thefile'];

if (!file_exists($ourFileName)) {

$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");

fclose($ourFileHandle);

}

but you probably wouldn't want the "or die()" part because that would leave you with a white page with an error message. You could do something like this:

Code:

$ourFileName = $vbulletin->options['thefile'];

if (!file_exists($ourFileName)) 

{

   $ourFileHandle = fopen($ourFileName, 'w');

   if ($ourFileHandle === FALSE)

   {

      // Do something here to handle error

   }

   else

   {

      fclose($ourFileHandle);

   }

}

Also, using "w" in the fopen call will truncate the file (make it empty), so if you don't want that, use either "r" or "a".

as long as its writeable its fine, the idea of this $ourFileName is that it shows a log
this worked for the end user but not the admin

what was happening was the following

1) user visited forum
2) if variable was true, it wrote to the $ourFileName
3) but some admins could not create this file automacially
( for me it worked ) for another website ( admin did not work )

i will use the above code to see how today goes with it

Well, the ability to create a file will depend on how the server permissions are set of course. You may have your set up to allow creation of a file anywhere whereas someone else doesn't (really you probably shouldn't allow it in the same directories that your php scripts are in, but I'm not a server config expert or anything). Maybe what you want to do is have an option to specify a directory, then instruct the admin to enter a path that has create permission for whatever user the web server runs as.

only, this is why the $variable is called to create a file somewhere

plugin : global start
$seeks this file upon a $true value, which allows the $event to be logged

the problem i am having with it is sharing this script which will also create the log in the same manner and folder, but they get the error message upon file creation and i dont

which i am trying to figure out if its and issue with fopen or
if (!file_exists($ourFileName))

which would be a permission issue somewhere on their webserver
