Hide array element

music_man

I am just wondering how I can hide a directory from showing? I've been playing around with files and it doesn't show the "." and ".." for parent folders but I can't seem to make it hide the "admin" folder (which is in the folder "Folder"). I have tried using unset but without success.

Any ideas?

<?php
$php_self = $_SERVER['PHP_SELF'];
$folder_path = "/opt/lampp/htdocs/websites/Folder/";
$title = $_GET["title"];
$titlepost = $_POST["titlepost"];
$filename = $_GET["filename"];
$filenamepost = $_POST["filename"];

if($_POST["action"]=="upload")
{
    foreach ($_FILES["file"]["error"] as $key => $error)
    {
        if ($error == UPLOAD_ERR_OK)
        {
            $tmp_name = $_FILES["file"]["tmp_name"][$key];
            $name = $_FILES["file"]["name"][$key];
            move_uploaded_file($tmp_name, "$folder_path/$titlepost/$name");
        }
    }
    $msg = "Uploaded files";
    $location=$php_self . '?title=' . $titlepost . '&page=upload';
    header("Location:$location");

Could you please be more specific about the problem? Perhaps just show us the lines of code that aren't working.

music_man

$scan_folders = scandir($folder_path);
$folder = array_splice($scan_folders, 2);

I would like $folder to not show the parent directories and the folder "admin".

Cheers

wempy

change

if($folder)
{
    for($i = 0; $i < count($folder); $i++)
    {

    echo "\n\n" . "<!-- start ". $folder[$i] . "-->" . "\n\n";
    echo '<ul type="square">';
    echo "<li>";
    echo $folder[$i];
    echo '&nbsp;|&nbsp;';

if($folder)
{
    for($i = 0; $i < count($folder); $i++)
    {
        if( !($folder[$i]=="admin") ){
            echo "\n\n" . "<!-- start ". $folder[$i] . "-->" . "\n\n";
            echo '<ul type="square">';
            echo "<li>";
            echo $folder[$i];
            echo '&nbsp;|&nbsp;'; 
            // rest of output . . .
       }

Here's a more efficient solution (it doesn't require an "if" statement every time the loop runs) and extends to any folder you don't want listed:

$hide = array(".", "..", "admin");
$scan_folders = scandir($folder_path);
foreach ($hide as $value) {
  if (($key = array_search($hide, $scan_folders)) !== FALSE) { unset($scan_folders[$key]); }
}

Then just insert the folders/files you don't want shown into the $hide array.

Also, I just realized that you won't have to use array_splice either since it will take out the . and .. directories in the above loop.

WDPEjoe

sorry, it should be

if (($key = array_search

One equals sign, not two.

music_man

Thanks for your replies.

Just trying to implement it...

$hide = array(".", "..", "admin");

$scan_folders = scandir($folder_path);

foreach ($hide as $value) {

  if (($key = array_search($hide, $scan_folders)) !== FALSE) 

  {
  unset($scan_folders[$key]); 
  }
}

$folder = ???;

if($folder)
{
    for($i = 0; $i < count($folder); $i++)
    {

Weedpacket

Or you could use [man]array_diff[/man] to remove the contents of $hide from the contents of $scan_folders.

music_man

Thanks for your help.

I cant seem to get array_diff to work:

$array1 = array(".", "..", "admin");
$array2 = scandir($folder_path);
$folder = array_diff($array2, $array1);

print_r($folder);

It shows a test directory I made but the array is all stuffed up.

Shows:

 | Delete | Rename | Upload file

* admin | Edit | Rename | Move | Delete
* test | Edit | Rename | Move | Delete

WDPEjoe

totally off-topic, but nice signature weedpacket

can you post what happens when you use

print_r(scandir($folder_path))

music_man

$array1 = array(".", "..", "admin");
$array2 = scandir($folder_path);
$folder = array_diff($array2, $array1);
print_r($array2);

Makes:

Array ( [0] => . [1] => .. [2] => admin [3] => sdf [4] => test )

music_man

Got it going:


$array1 = array(".", "..", "admin");
$array2 = scandir($folder_path);
$folder = array_diff($array2, $array1);

if($folder)
{

foreach ($folder as $fval) {


    echo "\n\n" . "<!-- start ". $fval . "-->" . "\n\n";
    echo '<ul type="square">';
    echo "<li>";
    echo $fval;
    echo '&nbsp;|&nbsp;';
    echo '<a href="' . $php_self . '?action=delete_folder&title=' . $fval . '">Delete</a>';
    echo '&nbsp;|&nbsp;';
    echo '<a href="' . $php_self . '?page=rename_folder&title=' . $fval . '">Rename</a>';
    echo '&nbsp;|&nbsp;';
    echo '<a href="' . $php_self . '?page=upload&title=' . $fval . '">Upload file</a>';
    echo '<ul type="square">';
    $array3 = array(".", "..", "admin");
    $dir = "$folder_path/$fval";
    $array4 = scandir($dir);
    $files = array_diff($array4, $array2);
            foreach ($files as $fival) {
            echo "\n\n" . "<!-- start ". $fival . "-->" . "\n\n";
            echo "<li>";
            echo $fival;
            echo '&nbsp;|&nbsp;';
            echo '<a href="' . $php_self . '?page=edit_file&title='. $fval . '&filename=' . $fival . '">Edit</a>';
            echo '&nbsp;|&nbsp;';
            echo '<a href="' . $php_self . '?page=rename_file&title='. $fval . '&filename=' . $fival . '">Rename</a>';
            echo '&nbsp;|&nbsp;';
            echo '<a href="' . $php_self . '?page=move_file&old_title='. $fval . '&filename=' . $fival . '">Move</a>';
            echo '&nbsp;|&nbsp;';
            echo '<a href="' . $php_self . '?action=delete_file&title=' . $fval . '&filename=' . $fival . '">Delete</a>';
            echo "</li>";
            }
    echo "</ul>";
    echo "</li>";
    echo "</ul>";
    echo "\n\n" . "<!-- end " . $fval . " -->" . "\n\n";
    }
}
else
{
    echo "<br />";
}

I may put that scanning dirctory into a function.

I now need to make it so that I acan have files list as well as folders. Is there a function to see whether the file type is a folder?

music_man

I'm trying to exclude files from showing as directories as I would like to show them on the same page but separated.

What function could I use to filter out whether it is a file or not? I have been trying is_file().

Weedpacket

Try is_file() and [man]array_filter[/man]....

I hope you don't write all your scripts like that.

I am not sure how to use array filter...

$array1 = array(".", "..", "admin");
$array2 = scandir($folder_path);
$folder = array_diff($array2, $array1);


function file2($var)
{
    return(is_file($folder));
}

function folder($var)
{
    return(is_dir($folder));
}

$array1 = array($folder);
$array2 = array($folder);

echo "File :\n";
print_r(array_filter($array1, "file2"));
echo "Folder:\n";
print_r(array_filter($array2, "folder"));

http://www.phptutorial.info/?array-filter

So I want to look up $folder and if there are any parts in the $folder array that is a file, return that under $array1 and if a folder, under $array2?

Weedpacket

$hide=array('.','..');
$files_and_directories = scandir('.');
$unhidden = array_diff($files_and_directories, $hide);
$files = array_filter($unhidden, 'is_file');
$directories = array_diff($unhidden, $files);
print_r($files_and_directories);
print_r($unhidden);
print_r($files);
print_r($directories);

music_man

I think I'd better show what the sturcture is of my folder.

The index.php file I am working on is in /admin

The files and folders I would like to create are in / (root).

I made a test index.php in root (/index.php) and I have commented out how I thought the system worked:

$hide= array('.','..','admin'); /* Array of things to hide */

$files_and_directories = scandir($folder_path); /* Opens $folder_path and puts contents into array */

$unhidden = array_diff($files_and_directories, $hide); /* Shows the files and folders that are not in the $hide array */

$files = array_filter($unhidden, 'is_file'); /* Filters all the $unhidden array variables into ones that are files */

$directories = array_diff($unhidden, $files); /* Filters all the $unhidden array variables into ones that are not in the $files array */

echo "Files and directories: ";
print_r($files_and_directories);
echo "<br /><br />";
echo "Unhidden: ";
print_r($unhidden);
echo "<br /><br />";
echo "Files: ";
print_r($files);
echo "<br /><br />";
echo "Directories: ";
print_r($directories);

print_r($directories);

makes: Array ( [3] => test.php )

And

print_r($files);

makes: Array ( )

Is the is_file not working? Should I use is_dir somewhere?

Thanks for your help

ClarkF1

Maybe it's because is_file doesn't return the filename, only true and false
