I have a directory with subfolders containing images. I need to display all these on one page, and also their folder name, so something like this:
echo Subfolder name
echo image, image, image
echo Subfolder2 name
echo image2, image2 , image2
etc
I've tried using
$images = glob($directory . "*.jpg");
but the problem is I have to exactly define the subfolder name in $directory, like "path/folder/subfolder/";
Is there any option like some "wildcard" that would check all subfolders and echo foreach subfolder name and its content?
Also, opendir and scandir can't be applied here due to server restrictions I can't control.
Glob normally have a recursive wildcard, written like /**/, but PHP Glob function doesn't support it. So the only way is to write your own function. Here's a simple one that support recursive wildcard:
<?php
function recursiveGlob($pattern)
{
$subPatterns = explode('/**/', $pattern);
// Get sub dirs
$dirs = glob(array_shift($subPatterns) . '/*', GLOB_ONLYDIR);
// Get files in the current dir
$files = glob($pattern);
foreach ($dirs as $dir) {
$subDirList = recursiveGlob($dir . '/**/' . implode('/**/', $subPatterns));
$files = array_merge($files, $subDirList);
}
return $files;
}
Use it like that $files = recursiveGlob("mainDir/**/*.jpg");

is there any way for RecursiveDirectoryIterator to echo files in subfolders separately based on folder and not all together?
Here is my example. I have a folder (event), which has multiple subfolders (logo, people, bands). But subfolder names vary for certain events, so I can't simply set to look inside these three, I need a "wildcard" option.
When I use RecursiveDirectoryIterator to echo out all images from these folders, it works, but I would like to separate these based on subfolder, so it echoes out folder name and all images from within below and then repeats for the next folder and so on.
Right now I use this:
<?php
$directory = "path/to/mainfolder/";
foreach (new RecursiveIteratorIterator(new
RecursiveDirectoryIterator($directory,RecursiveDirectoryIterator::SKIP_DOTS)) as $filename)
{
echo '<img src="'.$filename.'">';
}
?>
So, how do I make this echo like:
Logo
image, image, image
People
image, image, image
...
Thanks in advance for any useful tips and ideas.
for me, code is more readable when you put objects into variables with descriptive names then pass those on when instantiating other classes. I've used the RegexIterator() over the RecursiveFilterIterator() to filter just image file extensions (didn't want to get into extending the RecursiveFilterIterator() class for example). The rest of the code is simple iterating, extracting strings and page breaking.
NOTE: there is no error handling, best to add a try/catch to manage exceptions
<?php
$directory = 'path/to/mainfolder/';
$objRecursiveDirectoryIterator = new RecursiveDirectoryIterator($directory, RecursiveDirectoryIterator::SKIP_DOTS);
$objRecursiveIteratorIterator = new RecursiveIteratorIterator($objRecursiveDirectoryIterator);
// use RegexIterator() to grab only image file extensions
$objRegexIterator = new RegexIterator($objRecursiveIteratorIterator, "~^.+\.(bmp|gif|jpg|jpeg|img)$~i", RecursiveRegexIterator::GET_MATCH);
$lastPath = '';
// iterate through all the results
foreach ($objRegexIterator as $arrMatches) {
$filename = $arrMatches[0];
$pos = strrpos($filename, DIRECTORY_SEPARATOR); // find position of last DIRECTORY_SEPARATOR
$path = substr($filename, 0, $pos); // path is everything before
$file = substr($filename, $pos + 1); // file is everything after
$myDir = substr($path, strrpos($path, DIRECTORY_SEPARATOR) + 1); // directory the file sits in
if ($lastPath !== $path) { // is the path the same as the last
// display page break and header
if ($lastPath !== '') {
echo "<br />\n";
echo "<br />\n";
}
echo $myDir ."<br />\n";
$lastPath = $path;
}
echo $file . " ";
}
I'm trying to make an image gallery that scans a main directory and creates a separate album for each subdirectory.
My structure is similar to this:
-Gallery
--Subdir 1
---Image 1
---Image 2
--Subdir 2
---Image 1
---Image 2
The idea is that each album is going to be made of a div with a class of web-gallery. Then there will be a header for the album title made from the subdirectories name. After that a list is generated of each image. This is going to be a one page gallery. If possible I would like to have a variable that sets how many albums are listed that way if I have 30 subdirectories my page doesn't get too crowded.
So far I've written this but it doesn't work. I'm not getting any errors or logs though it just doesn't work.
$dirs = glob('img/gallery_temp/*', GLOB_ONLYDIR);
foreach($dirs as $val) {
echo '<div class="web-gallery">';
echo "<h3><span>ยป</span> ".basename($val). "</h3>";
echo '<ul class="web-gallery-list">';
$files = glob($val.'*.{jpg,png,gif}', GLOB_BRACE);
foreach($files as $file) {
echo "<li><a href='".$file."'><img src='" . $file . "' alt='description'></a></li> \r\n";
}
echo "</ul>";
echo "</div>";
}
Simply add a / before *.{jpg,png,gif} like this:
$files = glob($val.'/*.{jpg,png,gif}', GLOB_BRACE);
This is because $val doesn't have a final / for the directory.
You might consider using "readdir" instead of glob. Glob is to find pathnames matching a pattern, see here: http://php.net/manual/en/function.glob.php and is known to be a bit problematic.
Readdir, if your directory is entirely images might be easier to use: http://php.net/manual/en/function.readdir.php
Couple this with is_dir() http://php.net/manual/en/function.is-dir.php to resolve your directories vs files. Here is a snippet
<?php
if ($handle = opendir('/galleries')) {
while (false !== ($entry = readdir($handle))) {
// this is a subdirectory
if (is_dir($entry)) {
}
// this is a file
else {
echo $entry;
}
}
closedir($handle);
}
?>
If you make it a recursive function you could actually have it traverse a number of subdirectories creating galleries within galleries.
I also found this fantastic little snippet that is very elegant on another stack question: Get Images In Directory and Subdirectory With Glob
$rdi = new RecursiveDirectoryIterator("uploads/prevImgs/");
$it = new RecursiveIteratorIterator($rdi);
foreach($it as $oneThing)
if (is_file($oneThing))
echo '<img src="'.$oneThing.'" /><br />';
Using SPL Library (PHP >= 5)
Better solution in your case
is to use SPL library (the most cross-platform)
$directory = new RecursiveDirectoryIterator("./img/gallery_temp", FilesystemIterator::SKIP_DOTS);
// Flatten the recursive iterator, folders come before their files
$it = new RecursiveIteratorIterator($directory, RecursiveIteratorIterator::SELF_FIRST);
foreach($it as $fileinfo)
{
if($fileinfo->isDir())
{
// prevPath used to separate each directory listing and closing the bracket UL list
$prevPath = $it->getSubPath().DIRECTORY_SEPARATOR.$fileinfo->getFilename();
echo sprintf
(
"<div class='web-gallery'>
<h3><span>></span> %s</h3>
<ul>".PHP_EOL,
$fileinfo->getFilename()
);
}
if($fileinfo->isFile())
{
echo sprintf("<li><a href=''><img src='%s/%s' alt='description'></a></li>".PHP_EOL, $it->getSubPath(), $fileinfo->getFilename());
if($prevPath != $it->getSubPath())
echo("</ul>");
}
}
Note:
For more informations : SPL Documentation
DIRECTORY_SEPARATOR is a cross-platform constant, will use the
correct directory separator of the OS where are executed the code
FilesystemIterator::SKIP_DOTS, avoid to fetch the '.' and '..' dir
link level.
you can limit the depth of scanning with $it->setMaxDepth(5);
I'm trying to create a script that will read all of the other files in the directory and list them by grabbing the title meta tag for each one using the code below, but it's not working. If I'm reading the documentation correctly, get_meta_tags expects a URL by default, and if you want to point to a local file, you need to set the use_include_path parameter. But I don't think I'm doing that correctly.
$dir = '.';
$files = scandir($dir);
set_include_path($dir);
foreach ($files as &$value) {
$tags = get_meta_tags($value, true);
echo $tags['title'] . "<br/>";
}
According to the documentation it takes a URL or a filename-string. The only thing the second parameter is good for is if the files you want to parse are not on the current path, but are on the include path instead. That is not the case here, as you are already iterating over a path to get the filenames. You should do:
$dir = '.';
$files = scandir($dir);
foreach ($files as &$value) {
$tags = get_meta_tags($value);
echo $tags['title'] . "<br/>";
}
I'm very basic when it comes to PHP.
With my website, I have a directory called "uploads"
Within "uploads" I have 3 folders "Example1" "Example2" and "Example3"
Within each of the folders, they contain images.
I need to know how to use php to create a navigation for every sub directory.
So that if I add a new folder "Example4" it will give a navigation like:
Select what section you're looking for:
Example1 | Example2 | Example3
and if I later add new folders add them to the navigation.
EX:
Example1 | Example2 | Example3 | Example4 | Example5
Then once they click the link to go into the folder, have a code that displays all the images in that folder.
So far I have:
<?php
$files = glob("uploads/*.*");
for ($i=0; $i<count($files); $i++)
{
$num = $files[$i];
echo '<img src="/'.$num.'">'."<p>";
}
?>
but it will only display the images in the upload directory, not the images in Example1 and so on.
How on earth would I go about doing this? I'm doing it for a school project and have two weeks to complete it, but I am so lost. I only have knowledge with CSS, HTML, and the only PHP I know is php includes, so any help would be appreciated.
Since it seems that you are familiar with globs a bit, here is an example using the "glob" function. You can see a basic working example of what you are looking for here:
http://newwebinnovations.com/glob-images/
Here is how I have the example set up:
There are two PHP files, one is index.php and the other is list-images.php.
There is also a folder for images two subfolders that have images inside of them.
index.php is the file that finds the folders in the images folder and places them in a list with links list-images.php which will display the images inside of the folder:
$path = 'images';
$folders = glob($path.'/*');
echo '<ul>';
foreach ($folders as $folder) {
echo '<li>'.$folder.'</li>';
}
echo '</ul>';
The links created above have a dynamic variable created that will pass in the link to the list-images.php page.
Here is the list-images.php code:
if (isset($_GET['folder'])) {
$folder = $_GET['folder'];
}
$singleImages = array();
foreach (glob($folder . '/*.{jpg,jpeg,png,gif}', GLOB_BRACE) as $image) {
$imageElements = array();
$imageElements['source'] = $image;
$singleImages[$image] = $imageElements;
}
echo '<ul>';
foreach ($singleImages as $image) {
echo '<li><img src="'.$image['source'].'" width="400" height="auto"></li>';
}
echo '</ul>';
The links created here will link you to the individual images.
To get files of every specific folder ,pass it throw a get variable that contains folder's name,an then scan this folder an show images ,url should be like this :
listImages.php?folderName=example1
To have menu like what you want :
<?php
$path = 'uploads/' ;
$results = scandir($path);
for ($i=0;$i<count($results);$i++ ) {
$result=$results[$i];
if ($result === '.' or $result === '..') continue;
if (is_dir($path . '/' . $result)) {
echo "<a href='imgs.php?folderName=$result'>$result</a> ";
}
if($i!=count($results)-1) echo '|'; //to avoid showing | in the last element
}
?>
And here is PHP page listImages that scan images of a specific folder :
<?php
if (isset($_GET['folderName'])) $folder=$_GET['folderName'];
$path = 'uploads/'.$folder.'/' ;
$images = glob($path . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);
foreach ($images as $image) {
echo "<img src='$image' />";
}
?>
First of all, do read more PHP manual, for directory related: opendir, for files related: fopen
The following code is basically re-arranging the example code provided in opendir. What it does:
A scan_directory function to simply check if directory path is valid and is a directory, then proceed to do a recursive call if there's a child directory else just print out the file name.
The first if/else condition is just to ensure the base directory is valid.
I'll added ul and li to make it slightly more presentable.
$base_dir = 'upload';
if (is_dir($base_dir))
scan_directory($base_dir);
else
echo 'Invalid base directory. Please check your setting.';
// recursive function to check all dir
function scan_directory($path) {
if (is_dir($path)) {
if ($dir_handle = opendir($path)) {
echo '<ul>';
while (($file = readdir($dir_handle)) !== false) {
if ($file != '.' && $file != '..') {
if (is_dir($path . '/' . $file)) {
echo '<li>';
echo $file;
scan_directory($path . '/' . $file);
echo '</li>';
}
else
echo "<li>{$file}</li>";
}
}
echo '</ul>';
}
}
}
create image as subdirectory name with image name and save it in database
example:
subdirectory name: example2
image name: image.jpg
store image name in db as "example2/image.jpg"
I have the following code snippet. I'm trying to list all the files in a directory and make them available for users to download. This script works fine with directories that don't have sub-directories, but if I wanted to get the files in a sub-directory, it doesn't work. It only lists the directory name. I'm not sure why the is_dir is failing on me... I'm a bit baffled on that. I'm sure that there is a better way to list all the files recursively, so I'm open to any suggestions!
function getLinks ($folderName, $folderID) {
$fileArray = array();
foreach (new DirectoryIterator(<some base directory> . $folderName) as $file) {
//if its not "." or ".." continue
if (!$file->isDot()) {
if (is_dir($file)) {
$tempArray = getLinks($file . "/", $folderID);
array_merge($fileArray, $tempArray);
} else {
$fileName = $file->getFilename();
$url = getDownloadLink($folderID, $fileName);
$fileArray[] = $url;
}
}
}
Instead of using DirectoryIterator, you can use RecursiveDirectoryIterator, which provides functionality for iterating over a file structure recursively. Example from documentation:
$path = realpath('/etc');
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
echo "$name\n";
}
This prints a list of all files and
directories under $path (including
$path ifself). If you want to omit
directories, remove the
RecursiveIteratorIterator::SELF_FIRST
part.
You should use RecursiveDirectoryIterator, but you might also want to consider using the Finder component from Symfony2. It allows for easy on the fly filtering (by size, date, ..), including dirs or files, excluding dirs or dot-files, etc. Look at the docblocks inside the Finder.php file for instructions.
