Problem Passing File Names

[Jacob Lyles]

Hello,


I'm using the following function to display a list of files in a
directory in a HTML form that allows the user to delete files. Look at
the echo line. The links work fine, taking a user to
../directory/file.extention as expected. However, the value in the name
field of the input tag gets passed through POST as
/_/directory//file_extention, which messes up my unlink function. The
strange thing is I'm using \"/$dir/$file\" for both of them, so POST
must be doing something to my string.


function checklist_dir($ dir) {
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
if (filetype($dir . $file) != dir) {
echo "<input type=\"checkbox \" name=\"/$dir/$file\" /><a
href=\"/$dir/$file\">$file</a><br />";
}
}
closedir($dh);
}
}
}

Any help would be appreciated.

Thanks,
Jacob

Ugh, sorry, that code looks ugly. Here's the lines in question once
more:


echo "<input type=\"checkbox \" name=\"/$dir/$file\" /><a
href=\"/$dir/$file\">$file</a><br />";


Again, the link made with \"/$dir/$file\" works fine, taking a user to
../directory/file.extention while the name field is getting passed as
/_/directory//file_extention when I look at it using

foreach ($_POST as $key => $value) {
echo "$key<br />";
}

Dots in form values are replaced with underscores in PHP. This is a
throwback to when you would use $foo instead of $_POST['foo'].

(Heading: Dots in incoming variable names)

There's not really any way around it, so it might be worth using, e.g.
base64encode() and base64decode() at each end, as base64-encoded data
never contains dots.
