help on directory helper

[eluser]syntaxerror[/eluser]
hi,
i need help.
its my first time in using codeigniter.
i need a script that reads files in a folder into an array.
i think the directory helper can do it.
but i dont know how to use it.
in my controller
i made a function

Code:

function index()
    {
        $data['title'] = "DS Validator";
        $data['header'] = "DS Validator";
        $map = directory_map('C:/xampp/htdocs/AccmaRoster/', TRUE);
        $this->load->view('front_view', $data);
        
    }

and in my view

Code:

<?php foreach($map as $file): ?>
            <li>
                <ol>&lt;?php echo $file; ?&gt;</ol>
            </li>
&lt;?php endforeach; ?&gt;

but there is an error

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: map

Filename: views/front_view.php

Line Number: 26

Code:

A PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

Filename: views/front_view.php

Line Number: 29

You haven't added map to the data array.

[eluser]syntaxerror[/eluser]
ok

Code:

$data['map']= directory_map('C:/xampp/htdocs/AccmaRoster/', TRUE);

but can i use this? is this right?

Code:

$data['map']= directory_map('C:/xampp/htdocs/$_POST['directory']/', TRUE);

thanks

Code:

$data['map'] = directory_map('C:/xampp/htdocs/AccmaRoster/', TRUE); //change this line

[eluser]syntaxerror[/eluser]

Code:

$data['map'] = directory_map('C:/xampp/htdocs/AccmaRoster/', TRUE); //change this line

why? this is working. but i have to input the folder name manually, and the program will list down all files in that folder

[eluser]Yash[/eluser]
use base_url() function and don't use hard coding

[eluser]syntaxerror[/eluser]
the user has to enter the directory where he wants to view the list of files

Code:

$data['map'] = directory_map('C:/xampp/htdocs/AccmaRoster/'(the directory must be user entry), TRUE);

how to change the hardcoded directory to $_POST?

thanks

adding the post value without validation isn't a good idea. But when you validated the input you can add the $_POST value to the function.
