Topic awaiting preservation: Access send data/PHP

This is my form:
<form name="deleteThese" method="post" action="myphpfile.php">
<input type="hidden" name="process" value="5" />
<input type="checkbox" name="install.txt" />install.txt<br />
<input type="checkbox" name="license.txt" />license.txt<br />
<input type="checkbox" name="warranty.txt" />warranty.txt<br />
</form>

I want to delete all checked files. My PHP source (part of it):

$dir = opendir($path);

while ($file_name = readdir($dir)) {
If ((is_writable($file_name)) && ($file_name <> $thisFile)) echo ("<input type=\"checkbox\" name=\"". $file_name ."\" />". $file_name ."<br />\n");
echo $_POST[$file_name];
}
closedir($dir);

But $_POST[$file_name]; is emtpy.

What did i wrong?

I can only asue, that you use $_POST['file_name'] at one point and the bn before it you just use $file_name for your while statement..

prehaps you should change the other vars to $_POST['file_name']
or declare
$file_name = $_POST['file_name'];

Thanks, i found my mistake. But couldn't solve the main problem.
I changed my form:

<input type="checkbox" name="deleteFile" value="install.txt" />install.txt<br />
<input type="checkbox" name="deleteFile" value ="license.txt" />license.txt<br />
<input type="checkbox" name="deleteFile" value ="warranty.txt" />warranty.txt<br />

Now i can access $_POST["deleteFile"]. But only the last value. How can i access all 2 or 3 filenames?

:FAQ: How do I pass data from checkboxes in a form using PHP?

Also you'd better make sure there is nothing else in there which you want deleting in that folder as someone could have fun with that script

I was just getting ready to type out a post, but luckily I checked Emps link first because that's exactly what I was going to suggest.

If you name your checkboxes in that manner (name="checkbox[]") you can then loop through it in your code as an array:

foreach ($_POST['checkbox'] as $value) {

//do your stuff here
}

Thankyou Emps. The FAQ prevails once more.
