I'm using the jquery plugin jqueryFileTree with the PHP connector (slightly modified to give directories individual classes) to show the contents of a directory. I want to, however, hide all file extensions. Has anyone done something similar? I can think of one or two ways of implementing it but they seem overly-complicated...
Is there a relatively simple way of doing this in PHP?
Looking at the PHP connector code, you want to replace this:
// All files
foreach( $files as $file ) {
if( file_exists($root . $_POST['dir'] . $file) && $file != '.' && $file != '..' && !is_dir($root . $_POST['dir'] . $file) ) {
$ext = preg_replace('/^.*\./', '', $file);
echo "<li class=\"file ext_$ext\">" . htmlentities($file) . "</li>";
}
}
With this:
// All files
foreach( $files as $file ) {
if( file_exists($root . $_POST['dir'] . $file) && $file != '.' && $file != '..' && !is_dir($root . $_POST['dir'] . $file) ) {
$parts = explode(".", $file);
$ext = array_pop($parts);
$name = implode(".", $parts);
echo "<li class=\"file ext_$ext\">" . htmlentities($name) . "</li>";
}
}
Please note that the code in this provided connector script is not all that safe and you should take steps to prevent users abusing it to get access to sensitive folders.
Look at directoryIterator class and pathinfo() function.

I try to delete files with PHP. First I try to make a function to delete files but I want to delete one specific file and not all in the folder.
My function:
<?php
function del_tmp($file_name)
{
$dir = "mod_download/";
$verz = opendir($dir);
while ($file_name = readdir ($verz))
{
if($file_name != "." && $file_name != "..")
{
unlink($dir.$file_name);
}
}
closedir($verz);
}
?>
I think the problem is in this line: if($file_name != "." && $file_name != "..") but I have no idea how can i fix it.
Rather than processing over a whole directory as you only want to delete one file would it not be simpler and quicker to do
<?php
function del_tmp($file_name)
{
$dir = "mod_download/";
if ( file_exists($dir . $filename) ) {
unlink($dir . $file_name);
}
}
?>
The following code lists all the files contained in a certain folder in my local machine, as you can see I'm echoing the file path inside the tag using the href attribute correctly.
So the problem is that when I click on the tag, it doesn't take me to the file download unless I copy the link and paste it to another tab of the browser, why is this happening? How can I fix it?
<h5>Attached Files</h5>
<?php
$date = $dateCreated->format('d-m-Y');
$thepath = public_path().'/uploads/binnacle/'.$date.'/'.$activity->activity_id;
$handle = opendir($thepath);
$x = 1;
while(($file = readdir($handle))!= FALSE) {
if($file != "." && $file != ".." && $file != "thumbs" && $file != "thumbs.db") {
echo $x.".- "."<a href='$thepath/$file' target='_blank'>$file</a><br>";
$x++;
}
}
closedir($handle);
?>
NOTE: This happens with all file types including images, excel files, text documents, etc.
SOLUTION BY #WereWolf - The Alpha:
<?php
$date = $dateCreated->format('d-m-Y');
$thepath = "/uploads/binnacle/".$date."/".$activity->activity_id;
$handle = opendir(public_path().$thepath);
$x = 1;
while(($file = readdir($handle))!= FALSE) {
if($file != "." && $file != ".." && $file != "thumbs" && $file != "thumbs.db")
{
echo $x.'.- '.''.$file.'<br>';
$x++;
}
}
closedir($handle);
?>
Make some changes:
// Remove the public_path()
$thepath = 'uploads/binnacle/'.$date.'/'.$activity->activity_id;
Then in the link:
"<a href='" . asset($thepath/$file) . "' target='_blank'>$file</a><br>";
Note: Laravel has a File component, You may use that, check it in the source.
The purpose of this question can be served by writing independent function for each source & destination directory in an include file but I'm looking for a better approach.
The following function copy files from one source directory to one destination directory.
How can I use this function to copy file from another source directory to destination directory?
Is array(); applicable here or explode(); shall be the right choice or none of these is applicable in this case?
if (isset($_POST['submit'])) {
$old_umask = umask(0);
if (!is_dir($dst)) mkdir($dst, 0777);
umask($old_umask);
function recurse_copy($src,$dst) {
$dir = opendir($src);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
recurse_copy($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
//echo "$src";
}
$dir = $_POST['name'];
$src = "/home/user/public_html/directory/subdirectory/source/";
$dst = "/home/user/public_html/directory/subdirectory/destination/$dir/";
recurse_copy($src,$dst);
}
I have a directory with almost 60 images but in HD quality so theirs size are around 5 ~ 6 MB and load all them in a web page is to much time for server and browser so both hang up. I read this post and this other too and since I'm using PHP 5.4.20 in my server I'll like to use DirectoryIterator and LimitIterator but example leave in the post are not so explicit to me since I don't know how to move forward/backward in this cases. Can any give me some sample code about paginate files in a directory?
UPDATE: show some code
Right now this is how I read files:
function directoryToArray($directory, $recursive) {
$array_items = array();
if ($handle = opendir($directory)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if (is_dir($directory . "/" . $file)) {
if ($recursive) {
$array_items = array_merge($array_items, directoryToArray($directory . "/" . $file, $recursive));
}
$file = $directory . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
} else {
$file = $directory . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
}
}
}
closedir($handle);
}
return $array_items;
}
$images = directoryToArray("images/portfolio/");
for ($i = 0; $i < count($images); $i++) {
$old_img_name = explode('/', $images[$i]);
$new_img_name = $old_img_name[0] . "/" . $old_img_name[1] . '/large/' . $old_img_name[2];
echo '<div class="span4 element">';
echo '<div class="hover_img">';
echo '<img src="' . $images[$i] . '" alt="" />';
echo '<span class="portfolio_zoom"></span>';
echo '</div>';
echo '</div>';
}
Aristona's absolutely right. You should probably resize the images to an appropriate file-format, quality & size. At the very least if you're trying to make some sort of gallery, you could use something like image magick to make 'thumbnails' for the gallery where clicking on them may take you to the full-quality image.
Image magick is scriptable in a variety of languages to batch process your images and build thumbnails if you want it to run as a process, alternatively from the command line you can do it as a once off, something like what's mentioned here:
Batch resize images into new folder using ImageMagick
This is the starting portion of my code to list files in a directory:
$files = scandir($dir);
$array = array();
foreach($files as $file)
{
if($file != '.' && $file != '..' && !is_dir($file)){
....
I'm trying to list all files in a directory without listing subfolders. The code is working, but showing both files and folders. I added !is_dir($file) as you see in my code above, but the results are still the same.
It should be like this, I think:
$files = scandir($dir);
foreach($files as $file)
{
if(is_file($dir.$file)){
....
Just use is_file.
Example:
foreach($files as $file)
{
if( is_file($file) )
{
// Something
}
}
This will scan the files then check if . or .. is in an array. Then push the files excluding . and .. in the new files[] array.
Try this:
$scannedFiles = scandir($fullPath);
$files = [];
foreach ($scannedFiles as $file) {
if (!in_array(trim($file), ['.', '..'])) {
$files[] = $file;
}
}
What a pain for something so seemingly simple! Nothing worked for me...
To get a result I assumed the file name had an extension which it must in my case.
if ($handle = opendir($opendir)) {
while (false !== ($entry = readdir($handle))) {
$pos = strpos( $entry, '.' );
if ($entry != "." && $entry != ".." && is_numeric($pos) ) {
............ good entry
Use the DIRECTORY_SEPARATOR constant to append the file to its directory path too.
function getFileNames($directoryPath) {
$fileNames = [];
$contents = scandir($directoryPath);
foreach($contents as $content) {
if(is_file($directoryPath . DIRECTORY_SEPARATOR . $content)) {
array_push($fileNames, $content);
}
}
return $fileNames;
}
This is a quick and simple one liner to list ONLY files. Since the user wants to list only files, there is no need to scan the directory and return all the contents and exclude the directories. Just get the files of any type or specific type. Use * to return all files regardless of extension or get files with a specific extension by replacing the * with the extension.
Get all files regardless of extension:
$files = glob($dir . DIRECTORY_SEPARATOR . "*");
Get all files with the php extension:
$files = glob($dir . DIRECTORY_SEPARATOR . "*.php");
Get all files with the js extension:
$files = glob($dir . DIRECTORY_SEPARATOR . "*.js");
I use the following for my sites:
function fileList(string $directory, string $extension="") :array
{
$filetype = '*';
if(!empty($extension) && mb_substr($extension, 0, 1, "UTF-8") != '.'):
$filetype .= '.' . $extension;
else:
$filetype .= $extension;
endif;
return glob($directory . DIRECTORY_SEPARATOR . $filetype);
}
Usage :
$files = fileList($configData->includesDirectory, '');
With my custom function, I can include an extension or leave it empty. Additionally, I can forget to place the . before the extension and it will succeed.
