I am trying to find a solution to remove files from a directory listing. I found an example that works bery well for files within the same directory. However I assume that I would need to change directories but I am not understanding how to accomplish this.
Here is the example that works for files in the current directory
<?php
if(isset($_GET['delete'])){
$delurl=$_GET['delete'];
unlink($delurl);
}
?>
<?php
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
echo "<br><b>$entry - Delete<br></b>";
}
}
closedir($handle);
}
?>
Ok got it.
<?php
if(isset($_GET['delete'])){
$delurl=$_GET['delete'];
unlink($delurl);
}
?>
<?php
if ($handle = opendir('../videos/')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
echo "<br><b>$entry - Delete<br></b>";
}
}
closedir($handle);
}
?>
I just added the path after href=\?delete= and before $entry

I'm trying to allow user to delete images from a folder on server through html form and PHP.
Here's my html form markup along with PHP script generating list images from the folder mentioned before. I've added checkboxes with path+filename as value.
<form action="delete.php" method="POST">
<div id="formlist">
<?php
$path = ".";
$dh = opendir($path);
$i=1;
$images = glob($path."*.png");
while (($file = readdir($dh)) !== false) {
if($file != "." && $file != ".." && $file != "index.php" && $file != "form.css" && $file != ".htaccess" && $file != "error_log" && $file != "cgi-bin") {
echo "<div class='formshow'><a href='$path/$file' data-lightbox='Formularze' data-title='$file'><img class='formimg' src='$path/$file' width='500px'/></a><input type='checkbox' name='deleteform' value='$path/$file'></div>";
$i++;
}
}
closedir($dh);
?>
</div>
<input type="submit" value="Usun zaznaczone formularze">
</form>
Now, here's my delete.php file:
<?php
$path = ".";
$dh = opendir($path);
$i=1;
$deletepath = glob('deleteform');
while (($file = readdir($dh)) !== false) {
unlink($deletepath);
$i++;
}
?>
I keep this error:
Warning: unlink() expects parameter 1 to be a valid path, array given
I'm quite green with PHP, so I decided to ask you guys - how may I make this work? Should i unserialize() it and add [0], [1] counters?
To delete all itens in a folder user this:
$directory = "folder/";
if ($cat_handle = opendir($directory)) {
while (false !== ($entry = readdir($cat_handle))) {
#unlink($directory.$entry);
}
closedir($cat_handle);
}
You need delete itens or folder?
if you need delete specific item:
$file_name = "fulano.jpg";
if ($handle = opendir('folder/')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
if($entry == $file_name){
#unlink('folder/'.$name);
}
}
}
closedir($handle);
}
I believe it works no seu caso, change to accept array now.
I am reading a rootpath and listing all the folder. I have to add some child node to every folder programatically ?
<?php
$rootpath = 'D:/Storage/';
if ($handle = opendir($rootpath)) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
echo "<li><a href=/hi.php?dev=$entry&action=viewcam>$entry</a>";
}
}
closedir($handle);
?>
I am getting like
- folder1
- folder2
but I want like
- folder1
Appple
orange
- folder2
Appple
orange
Any suggestion ?
There is no need to specifically "create a node" on the server side for this. All you have to do is output the html markup you want to have:
<?php
$rootpath = 'D:/Storage/';
if ($handle = opendir($rootpath)) {
echo "<ul>\n";
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
echo "<li>$entry</li>\n";
echo "<ul>\n";
foreach (['Apple', 'orange'] as $fruit) {
echo "<li>".$fruit."</li>\n";
}
echo "</ul>\n";
}
}
echo "</ul>\n";
}
closedir($handle);
?>
(I fixed a few minor issues with your code on-the-fly...)
Obviously this is just an example to show the basic approach.
I have a script file. that list files and folder in a directory.. I want to hide certain files and folder. How do I do that?
<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle)))
{
if (($file != ".")
&& ($file != ".."))
{
$thelist .= '<LI>'.$file.'';
}
}
closedir($handle);
}
?>
<P>List of files:</p>
<UL>
<P><?=$thelist?></p>
</UL>
<?php
$files_to_hide = array('file1.txt', 'file2.txt');
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle)))
{
if (($file != ".") && ($file != "..") && !in_array($file, $files_to_hide))
{
$thelist .= '<LI>'.$file.'';
}
}
closedir($handle);
}
?>
<P>List of files:</p>
<UL>
<P><?=$thelist?></p>
</UL>
Put the list of filenames you want to exclude in an array.
After that, you check whether the filename exists in the array before adding it to $thelist.
You can add that as part of the if() statement that checks if the filename is . or ...
Something like this:
<?php
$bannedFiles = Array(".", "..", "example");
if ($handle = opendir('.')){
while (false !== ($file = readdir($handle)))
{
$banned = false;
foreach ($bannedFiles as $bFile){
if ($bFile == $file){
$banned = true;
}
}
if (!$banned){
$thelist .= '<LI>'.$file.'</LI>';
}
}
closedir($handle);
}
?>
<P>List of files:</p>
<UL>
<P><? echo $thelist;?></p>
</UL>
If you know the names of the files/directories you want to hide, you can maintain a set-map of such entries, and filter them out within the while loop.
Your set-map would look like this:
$items_to_hide = [ "/home/me/top_secret" => 1, "/home/me/passwords.txt" => 1, ... ]
And then you would modfiy your while loop like this:
while (false !== ($file = readdir($handle)))
{
// check map if said file is supposed to be hidden, if so skip current loop iteration
if($items_to_hide[$file]) {
continue;
}
if (($file != ".")
&& ($file != ".."))
{
$thelist .= '<LI>'.$file.'';
}
}
Hope this helps.
EDIT:
Also wanted to mention, using a php ordered array as your "blacklist" is quite efficient, as a single lookup will occur in almost constant time. Hence you can grow your blacklist as large as you want and still see decent performance.
I was wondering if anyone could help me write a PHP script for me that renames all the files in a directory in a sequence.
So...
DSC_10342.JPG -> 1.JPG
DSC_10343.JPG -> 2.JPG
DSC_10344.JPG -> 3.JPG
and so on.
Here's my version:
// open the current directory (change this to modify where you're looking)
$dir = opendir('.');
$i = 1;
// loop through all the files in the directory
while (false !== ($file = readdir($dir)))
{
// if the extension is '.jpg'
if (strtolower(pathinfo($file, PATHINFO_EXTENSION)) == 'jpg')
{
// do the rename based on the current iteration
$newName = $i . '.jpg';
rename($file, $newName);
// increase for the next loop
$i++;
}
}
// close the directory handle
closedir($dir);
Use rename to rename the files. You can use this handy script to loop through all files in a directory:
<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}
?>
Then it's just a matter of looking at the filenames ($file) and figuring out what number to give them. If you need more help than that, just tell me and I'll give more details.
Try this:
$handler = opendir($directory);
$index = 1;
while ($file = readdir($handler)) {
if ($file != "." && $file != "..") {
rename($directory."/".$file, $directory."/".$index.".JPG");
$index++;
}
}
closedir($handler);
Using someone's snippet it would look like this:
<?php
$path = '.';
$i = 1;
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." && is_file($path.'/'.$file)) {
$oldname = $path.'/'.$file;
$path_info = pathinfo($oldname);
rename($oldname, $path.'/'.($i++).'.'.$path_info['extension']);
}
}
closedir($handle);
}
?>
It will rename files with all extensions and skip directories that may be inside your directory.
I am very much a beginner when it comes to using PHP. I was given this code, to try and output the contents of a files on a folder, onto a server, but my issue is I do not know how to read and alter this code to fit my specific file path. Can someone help me out with this, and lets just use the name folder as an arbitrary pathname.
<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}
?>
<?php
$dir_path = '.'; // '.' = current directory.
// '..' = parent directory.
// '/foo' = directory foo in the root file system
// 'folder' = a dir called 'folder' inside the current dir
// 'a/b' = folder 'b' inside 'a' inside the current dir
// '../a' = folder 'a' inside the parent directory
if ($handle = opendir($dir_path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}
?>
<?php
$path = '.';
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}
?>
