Is there a glitch with opendir/readdir? - php

Here is my PHP code:
<?php
// Enumerate the directories in styles
$styles_dir = 'styles/';
if($handle = opendir($styles_dir))
{
while(FALSE !== ($file = readdir($handle)))
{
echo $file . '(' . is_dir($file) . ')<br>';
}
}
?>
Here are the directories in styles:
http://files.quickmediasolutions.com/php.jpg
And here is the output:
.(1)
..(1)
forest()
industrial()
Why aren't forest and industrial directories?

The path for is_dir is relative to the base file, so you really need to do a test like
is_dir($styles_dir . '/' . $file)
Note that this is masked for the . and .. "directories" as these exist everywhere.

You need to prefix the directory name to the file name as is_dir works relative to the current directory.
Change
echo $file . '(' . is_dir($file) . ')<br>';
to
echo $file . '(' . is_dir("$styles_dir/$file") . ')<br>';
Alternatively you can change the directory to $styles_dir using chdir and then your current code will work.

How do i set up path and folder pattern in PHP?

So I am trying to set up path for my pdf files that are stored in a folder structure. The file that has to be selected depends on the user input.
I want to set up first the absolute path and then a folder pattern.
The folder where I have stored my files is:
C:\Apache24\htdocs\archivedb\Tourenfahrer\2017\5
The last three folders changes as per user input.
I have setup my root directory in my config.php like this:
define( 'ROOT_DIR', dirname(__FILE__) );
Now in my php file I am recieving my variables, which will be my folder names to search for the files.
<?php
require_once 'conf/config.php';
if (!empty($_REQUEST['magName'] && $_REQUEST['year'] && $_REQUEST['issue']
)) {
$magazineName = $_REQUEST['magName'];
$year = $_REQUEST['year'] ;
$issue = $_REQUEST['issue'] ;
}
Now Please tell how to access the respective folder using these variables?
and how can i set up a pattern with this using glob(); ?
Please try this
define('ROOT_DIR', dirname(__FILE__));
define('DS', DIRECTORY_SEPARATOR);
if (!empty($_REQUEST['magName'] && $_REQUEST['year'] && $_REQUEST['issue'])) {
$magazineName = $_REQUEST['magName'];
$year = $_REQUEST['year'];
$issue = $_REQUEST['issue'];
$dir = $magazineName . DS . $year . DS . $issue;
echo "<h3>Use scandir:</h3>";
$files = scandir(ROOT_DIR . DS . $dir);
foreach ($files as $file) {
echo basename($file) . "<br>";
}
echo "<h3>Use glob:</h3>";
foreach (glob($dir . DS . '*') as $filename) {
echo basename($filename) . "<br>";
}
}

rename images and move the renamed images in newly created directory

Here i want to create a new directory called c:/xampp/htdocs/haha/tour/ and in the directory i want to move my renamed images .Here ,i managed to create the new directory but can't move and rename my images.How can i solve this problem??
$dir='c:/xampp/htdocs/practice/haha';
$i=1;
if(is_dir($dir)){
echo dirname($dir).'</br>';
$file=opendir($dir);
while(($data=readdir($file))!==false){
if($data!='.' && $data!='..'){
$info=pathinfo($data,PATHINFO_EXTENSION);
if(!file_exists($dir.'/tour')){
mkdir($dir.'/tour/');
}
rename($dir.$data,$dir.'/tour/'.'image '.$i.'.jpg');
$i++;
}
}
}
You're missing some /:
rename($dir.$data,$dir.'/tour/'.'image '.$i.'.jpg');
^---
$data doesn't contain ANY /, so what you're building is
rename('c:/xampp/htdocs/practice/haha' . 'foo', etc...)
which becomes
rename('c:/xampp/htdocs/practice/hahafoo', etc...)
^^^^^^^---doesn't exist
Try
rename($dir .'/' . $data,$dir.'/tour/'.'image '.$i.'.jpg');
^^^^^^^^
instead.
This should work for you:
Here I just get all images from your directory with glob(). I create the directory if it doesn't exist already with mkdir() and then move all images
with rename().
<?php
$dir = "c:/xampp/htdocs/practice/haha";
$files = glob($dir . "/*.{jpg,png,gif,jepg}", GLOB_BRACE);
//Create directory
if (!file_exists($dir . "/tour")) {
mkdir($dir . "/tour");
}
//Move all images
foreach($files as $key => $file) {
rename($dir . "/" .$data, $dir . "/tour/image" . ($key+1) . ".jpg");
}
?>

PHP Delete File script

I have a basic PHP script that displays the file contents of a directory. Here is the script:
<?php
$Dept = "deptTemplate";
if(isset($_REQUEST['dir'])) {
$current_dir = $_REQUEST['dir'];
} else {
$current_dir = 'docs';
}
if ($handle = opendir($current_dir)) {
while (false !== ($file_or_dir = readdir($handle))) {
if(in_array($file_or_dir, array('.', '..'))) continue;
$path = $current_dir.'/'.$file_or_dir;
if(is_file($path)) {
echo '`'.$file_or_dir.' - [Delete button/link]<br/>`';
} else {
echo '``'.$file_or_dir."\n`` - [Delete button/link]`<br/>`";
}
}
closedir($handle);
}
?>
I am trying to create a delete link/button that displays next to each file and when clicked, the corresponding file will be deleted. Would you know how to do this?
Use the built-in unlink($filepath) function.
Sure, you'd have to use unlink() and rmdir(), and you'd need a recursive directory removal function because rmdir() doesn't work on directories with files in them. You'd also want to make sure that the deletion script is really secure to stop people from just deleting everything.
Something like this for the recursive function:
function Remove_Dir($dir)
{
$error = array();
if(is_dir($dir))
{
$files = scandir($dir); //scandir() returns an array of all files/directories in the directory
foreach($files as $file)
{
$fullpath = $dir . "/" . $file;
if($file == '..' || $file == '.')
{
continue; //Skip if ".." or "."
}
elseif(is_dir($fullpath))
{
Remove_Dir($fullpath); //recursively remove nested directories if directory
}
elseif(is_file($fullpath))
{
unlink($fullpath); //Delete file otherwise
}
else
{
$error[] = 'Error on ' . $fullpath . '. Not Directory or File.' //Should be impossible error, because everything in a directory should be a file or directory, or . or .., and thus should be covered.
}
}
$files = scandir($dir); //Check directory again
if(count($files) > 2) //if $files contains more than . and ..
{
Remove_Dir($dir);
}
else
{
rmdir($dir); //Remove directory once all files/directories are removed from within it.
}
if(count($error) != 0)
{return $error;}
else
{return true;}
}
}
Then you just need to pass the file or directory to be deleted through GET or something to the script, probably require urlencode() or something for that, make sure that it's an authorized user with permissions to delete trying to delete the stuff, and unlink() if it's a file, and Remove_Dir() if it's a directory.
You should have to prepend the full path to the directory or file to the directory/file in the script before removing the directory/file.
Some things you'll want for security is firstly making sure that the deletion is taking place in the place it's supposed to, so someone can't do ?dir=/ or something and attempt to delete the entire filesystem from root, which can probably be circumvented by prepending the appropriate path onto the input with something like $dir = '/home/user/public_html/directories/' . $_GET['dir'];, of course then they can potentially delete everything in that path, which means that you need to make sure that the user is authorized to do so.
Need to keep periodic backups of files just in case.
Something like this? Not tested...
<?php
echo '`'.$file_or_dir.' - [Delete button/link]<br/>`';
?>
<?php
if ($_GET['del'] == 1 && isset($_GET['file_or_dir']){
unlink ("path/".$_GET['file_or_dir']);
}
?>
I've worked it out:
I added this delete link on the end of each listed file in the original script:
- < a href="delete.php?file='.$file_or_dir.'&dir=' . $dir . '"> Delete< /a>< br/>';
This link takes me to the download script page, which looked like this:
<?php
ob_start();
$file = $_GET["file"];
$getDir = $_GET["dir"];
$dir = 'docs/' . $getDir . '';
$isFile = ($dir == "") ? 'docs/' . $file . '' : '' . $dir . '/' . $file . '';
if (is_file($isFile)){
if ($dir == "")
unlink('docs/' . $file . '');
else
unlink('' . $dir . '/' . $file . '');
echo '' . $file . ' deleted';
echo ' from ' . $dir . '';
}
else{
rmdir('' . $dir . '/' . $file . '');
echo '' . $dir . '/' . $file . ' deleted';}
header("Location: indexer.php?p=" . $getDir . "");
ob_flush();
?>
It all works brilliantly now, thank you all for your help and suggestions :)

Moving files into directory in foreach loop?

i've no idea how to do that and need your help!
i have an array of filenames called $bundle. (file_one.jpg, file_two.pdf, file_three.etc)
and i have the name of the folder stored in $folder. (my_directory)
i now would like to move all the files stored in $bundle to move to the directory $folder.
how can i do that?
//print count($bundle); //(file_one.jpg, file_two.pdf, file_three.jpg)
$folder = $folder = PATH . '/' . my_directory;
foreach ($bundle as $value) {
//rename(PATH.'/'.$value, $folder . '/' . $value);
}
just so it's not confusing: PATH just stores the local file-path im using for my project. in my case it's just the folder i'm working in-so it's "files".
i have no idea which method i have to use for this and how i could solve that!
thank you for your help!
The code given by you should work with minor changes:
$folder = PATH . '/' . 'my_directory'; // enclose my_directory in quotes.
foreach ($bundle as $value) {
$old = PATH.'/'.$value, $folder;
$new = $folder . '/' . $value;
if(rename($old,$new) !== false) {
// renamed $old to $new
}else{
// rename failed.
}
}
$folder = PATH . '/' . $folder;
foreach ($bundle as $value) {
$old = PATH.'/'.$value;
$new = $folder . '/' . $value;
if(rename($old,$new) !== false) {
// renamed $old to $new
}else{
// rename failed.
}
}
Untested but should work:
function bulkMove($src, $dest) {
foreach(new GlobIterator($src) as $fileObject) {
if($fileObject->isFile()) {
rename(
$fileObject->getPathname(),
rtrim($dest, '\\/') . DIRECTORY_SEPARATOR . $fileObject->getBasename()
);
}
}
}
bulkMove('/path/to/folder/*', '/path/to/new/folder');
Could add some checks to see if the destination folder is writable. If you dont need wildcard matching, change the GlobIterator to DirectoryIterator. That would also eliminate the need for PHP5.3

PHP copy says file does not exist when it does

im using the following code;
if( ! file_exists( $path ) ) { die( "'" . $path . "' not vaild path"); }
copy( $path, ltrim($create_folder . ltrim($path, "./"), ".") );
echo "'" . $path. "' => '" . $create_folder . ltrim($path, "./") . "'<br />";
The first if statement returns true yet the copy function returns;
Warning: copy('./files/c7a628cba22e28eb17b5f5c6ae2a266a/0003.css') [function.copy]: failed to open stream: No such file or directory
'./files/c7a628cba22e28eb17b5f5c6ae2a266a/0003.css' => './224efcdebda48350056af291f64a9311/files/8b571e7fbf9bacf4473024b11f78bc0dfiles/c7a628cba22e28eb17b5f5c6ae2a266a/0003.css'
If anyone knows why it would be much appreciated.
You might notice that your second half is missing a slash. As in, one of your path elements is "8b571e7fbf9bacf4473024b11f78bc0dfiles" instead of "8b571e7fbf9bacf4473024b11f78bc0d/files". Try $create_folder . '/' . ltrim($path, "./")
But the real answer is "your file actually does not exist. No, really, PHP is correct". It's just talking about the destination not existing; the source is fine.
