No spaces and dots?

[jokkemokke]

I'm trying to make a filemanager in PHP, where it should be possible to delete files by checking some checkboxes in a form.

I use the name of the files as the checkbox name, and when the "delete" button in the form is pressed, the parameter f.ex. filename1.doc=on is send to the php page, which should take care of the deleting, if I have choosen to delete the file with the name filename1.doc.

In the page where I receive the parameter I have the following code:

$checkbox_name = "filename1.doc";

if ($_GET[$checkbox_name] == 'on' )
  /* Do the deleting etc... */

The problem that this check is never true. But if I replace the '.' in the filename with f.ex. an 'a' or some other letter and make the following check where I receive the parameters:

$checkbox_name = "filename1adoc";

if ($_GET[$checkbox_name] == 'on' )
  /* Do the deleting etc... */

..the check is performed ok. I also have the problem with spaces in the filename.

Is there some kind of string convert function in PHP, which can help me solve this problem, or do I manually have to make a string replace on all charecters, which apperently can't be used as a get/post parameter?

Ok, I've just tried to make a

print_r($_GET);

where I receive the parameters, and I can see, that all spaces and dots are replaced with underscores.

So I guess I have to replace the spaces and dots in the string I wan't to compare with , with underscores too.

Is there an easy way to do this? Are other charecters replaced withe underscores too?

Better to make the checkbox values = filename.

<input type='checkbox' name='file[]' value='$filename'>$filename

etc

Then, to process

foreach ($_POST['file'] as $filename) {
     // code to delete $filename
}
