[RESOLVED] FIles in directory

zzz

I need to add a functionality that will allow users upload up to 5 images.

Each user has his own directory.
I guess I need to check directory and see how many image files already exist in this directory and put them in an array and then print out list via a loop.

I think the theory is there...

$userDir = 'johndoe';

// go through directory and put all files ending on .jpg into an array
$imgArray = array(....);

$imgCount = count($imgArray);

if ($imgCount < 5) {
   echo 'You can still add '. 5 - $imgCount .' images.'; 
} echo {
   for($i=0; $i =< $imgCount; $i++)
  {
     echo '<img src="$imgArray[$i]">\n';
  }
}

That's all I've got so far... Shall I use something like file_exists? Need a push in the right direction.

Try using [man]glob/man with a "." pattern - that will give you an array of all files in the directory matching that format (e.g., it will exclude the "." and ".." directory references).

Brilliant. I actually found a whole function that would do everything I need that was posted just a week ago!

To continue off of bradgrafelman's suggestion:

$number_of_jpgs = count(glob("/userdir/*.jpg"));
if ($number_of_jpgs < 5){
  // display the upload form
}

Great!

I'd like to use this $number_of_jpgs option, but I'm afraid wild card does not work here...

Then some combination of scandir() and then doing a regular expression match on each of the file's extensions is one other option. This is assuming you mean that you can't use glob() ?

I think it's a problem with my path after all. I put a test file in the same dir and was able to count it... Sorry about the confusion.
