[PHP-DEV] Delete checked files

[Nautilis]

Hi everybody,

I show a list of files that I upload to the user's folder using the next
code:

$path= ../clients/$user;
$dir = opendir ($root);
while ($archivo = readdir ($dir))
   {
$size = filesize($path/$filename);
$size = ($size/1024);
$size = intval($size * 100 ) / 100;
if ($filename!= .  $filename!=..)
{
echo trtda
href='$path/$filename'$filename/a/tdtd$size Kb/td/tr;
}
}

I want to add a checkbox in every file i get in the user's folder. My
question is:

Is there any way to use some kind of function to delete selected files? I am
not sure if i can use javascript to evaluate which is checked and how. And
after that evaluation, how to call a unlink ($filename) to delete the files.

Any help would be greatly appreciated.

Nau

[PHP-DEV] delete checked files

Why not start an html form element before u start outputting the tr /s and
td /s of ur table.
Finish it at the end of ur while loop, oh...and include a submit button.

The submit calls either a new script or the same script itself, only using
url query strings to specify a different part of the code.

Each input type=checkbox should be NAMED with the filename of each file
it is representing. Or possibly with a small identifier to differentiate
between the file reference and the input name, say c_ at the front. And
perhaps you ought to remove the file-extention.

So if your directory contained mydoc.doc, the checkbox would be named
c_mydoc

Then u use a while loop exactly the same as in the code u pasted to the
list, but instead of using the filename as a string that you then echo to
the screen, you simply strip off the file extension and add c_ at the
beginning. You will now be referring to each of the chechbox form elements.

Simply while-loop your way through the form elements (each identified by the
file in the directory so you will know when/if an element exists because you
will still be looping through the opendir() command, or not), asking it if
it is checked or not  and delete it

if ($c_mydoc){
unlink ($regular_filename_WITH_extension_and_WITHOUT_c_)
}
