the code is
<?php
$files = array();
$dir = opendir('/xampp/htdocs/myfun/template/home');
while(($file = readdir($dir)) !== false) {
if($file !== '.' && $file !== '..') {
$files[] = $file;
}
}
closedir($dir);
//sort($files);
$i=0;
foreach($files as $key) {
echo "<iframe align='center' width='100%' height='605px' src='$key' title='$files[$i]'></iframe>";
break;
}
?>
i want to show templates onclick next/prev button.horizontally.
like slider.
please help
Correct logic to iterate a directory in while loop is false != ($file = readdir($dir)), where you assign file name first and check it's not false.
Also you can print title with $key itself. $files[$i] and $i variable is not required.
In order to iterate through all files of directory remove break, this will cause to end the loop after first iteration.
<?php
$files = array();
$dir = opendir('/xampp/htdocs/myfun/template/home');
while(false != ($file = readdir($dir)))
{
if($file !== '.' && $file !== '..')
{
$files[] = $file;
}
}
closedir($dir);
//sort($files);
foreach($files as $key)
{
echo "<iframe align='center' width='100%' height='605px' src='$key' title='$key'></iframe>";
}
?>

So, simply want my webdrive folder to be "browseable", so I found this script that does it for me.
The problem is, that the list is not sorted by name
How needs the code to be modified so its sorted by filename?
<?php
$dir_open = opendir('.');
while(false !== ($filename = readdir($dir_open))){
if($filename != "." && $filename != ".."){
$link = "<a href='./$filename'> $filename </a><br />";
echo $link;
}
}
closedir($dir_open);
?>
You can store the filenames in an array, then sort them using sort()
$files = [];
$dir_open = opendir('.');
while(false !== ($filename = readdir($dir_open))){
if($filename != "." && $filename != ".."){
$files[] = $filename; // store filename
}
}
closedir($dir_open);
// Then, sort and display
sort($files);
foreach ($files as $filename) {
$link = "<a href='./$filename'> $filename </a><br />";
echo $link;
}
<?php
$dir = opendir('C:\Users\Prometheus\Desktop\milkmaid');
$i = 1;
// loop through all the files in the directory
while (false !== ($file = readdir($dir)))
{
if ($file != "." && $file != "..") {
$newName = $i.'.mp4';
$oldname = $file;
rename($oldname, $newName);
$i++;
}
}
?>
when i run above script, i am getting following error:
The system cannot find the file specified. (code: 2)
$dir is not a string. You can't concatenate $file with it. You will need to put the directory in a separate variable, and not forget to put a / in between directory and filename.
Adding $dir in the rename() works for me
<?php
$dir = opendir('C:\Users\Prometheus\Desktop\milkmaid');
$i = 1;
// loop through all the files in the directory
while (false !== ($file = readdir($dir)))
{
if ($file != "." && $file != "..") {
$newName = $i.'.mp4';
$oldname = $file;
rename($dir.$oldname, $dir.$newName);
$i++;
}
}
?>
Use it like this :-
$directory = '/public_html/testfolder/';
$i=1;
if ($handle = opendir($directory)) {
while (false !== ($fileName = readdir($handle))) {
$newName = $i.'.mp4';
rename($directory . $fileName, $directory . $newName);
$i++:
}
closedir($handle);
}
This worked for me
<?php
$counter = 1;
$dir = 'D:\files'; //path of folder
if ($handle = opendir($dir))
{
while (false !== ($fileName = readdir($handle)))
{
if($fileName != '.' && $fileName != '..')
{
$newName = $counter . " - " . $fileName;
rename($dir."/".$fileName, $dir."/".$newName);
$counter++;
}
}
closedir($handle);
}
?>
I am trying to sort a list of directories according to the contents of a text file within each directory.
So far, I am displaying the list of directories:
$user = $_GET['user'];
$task_list = $_GET['list'];
if ($handle = opendir("../users/$user/tasks/$task_list/"))
{
$files = array();
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != ".." && $file != ".htaccess")
{
array_push($files, $file);
}
}
closedir($handle);
}
//Display tasks
sort($files);
foreach ($files as $file)
{
echo "$file";
}
Each directory has a text file within it called due.txt, I would like to sort the list of directories according to the contents of this file due.txt.
So far, I have tried:
$user = $_GET['user'];
$task_list = $_GET['list'];
if ($handle = opendir("../users/$user/tasks/$task_list/"))
{
$files = array();
$tasksSort = array();
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != ".." && $file != ".htaccess")
{
$taskSort = file_get_contents("../users/$user/tasks/$task_list/$file/due.txt");
array_push($files, $file);
array_push($tasksSort, $taskSort);
}
closedir($handle);
}
//Sort tasks and display
sort($tasksSort);
foreach ($files as $file)
{
echo "$file";
}
}
But the $tasksSort array doesn't seem to have any content to sort...?
sort($tasksSort);
foreach ($tasksSort as $file)
{
echo "$file";
}
I'm loading a folder full of images in, to create a jQuery Image Gallery.
There are currently 100 images being loaded in to create the gallery. I've got all that to load without issue.
All I want to do is make the image(s) that are loaded, load in randomly.
How do I achieve this?
My code is :
<?php
$folder = "images/";
$handle = opendir($folder);
while(($file = readdir($handle)) !== false) {
if($file != "." && $file != "..")
{
echo ("<img src=\"".$folder.$file."\">");
}
}
?>
Thanks in advance.
Just store all the image paths in an array and do a random shuffle of the array. And then echo the elements
<?php
$folder = "images/";
$handle = opendir($folder);
$imageArr = array();
while(($file = readdir($handle)) !== false) {
if($file != "." && $file != "..")
{
$imageArr[] = $file;
}
shuffle($imageArr); // this will randomly shuffle the image paths
foreach($imageArr as $img) // now echo the image tags
{
echo ("<img src=\"".$folder.$img."\">");
}
}
?>
Traverse the directory and store the image file names into an array and randomly select path names from the array.
A basic example:
$dir = new DirectoryIterator($path_to_images);
$files = array();
foreach($dir as $file) {
if (!$fileinfo->isDot()) {
$files[] = $file->getPathname();
}
}//$files now stores the paths to the images.
You can try something like this:
<?php
$folder = "images/";
$handle = opendir($folder);
$picturesPathArray;
while(($file = readdir($handle)) !== false) {
if($file != "." && $file != "..")
$picturesPathArray[] = $folder.$file;
}
shuffle($picturesPathArray);
foreach($picturesPathArray as $path) {
echo ("<img src=\"".$path."\">");
}
?>
I created a script that list the directories in the current directory
<?php
$dir = getcwd();
if($handle = opendir($dir)){
while($file = readdir($handle)){
if(is_dir($file)){
echo "$file<br />";
}
}
?>
but the problem is, I am seeing this ".." and "." right above the directory listings, when someone clicks it, they get redirected one level up the directories.. can someone tell me how to remove those ".." and "." ?
If you use opendir/readdir/closedir functions, you have to check manually:
<?php
if ($handle = opendir($dir)) {
while ($file = readdir($handle)) {
if ($file === '.' || $file === '..' || !is_dir($file)) continue;
echo "$file<br />";
}
}
?>
If you want to use DirectoryIterator, there is isDot() method:
<?php
$iterator = new DirectoryIterator($dir);
foreach ($iterator as $fileInfo) {
if ($fileInfo->isDot() || !$fileInfo->isDir()) continue;
$file = $fileinfo->getFilename();
echo "$file<br />";
}
?>
Note: I think that continue can simplify this kind of loops by reducing indentation level.
Or use glob:
foreach(glob('/path/*.*') as $file) {
printf('%s<br/>', $file, $file);
}
If your files don't follow the filename dot extension pattern, use
array_filter(glob('/path/*'), 'is_file')
to get an array of (non-hidden) filenames only.
Skips all hidden and "dot directories":
while($file = readdir($handle)){
if (substr($file, 0, 1) == '.') {
continue;
}
Skips dot directories:
while($file = readdir($handle)){
if ($file == '.' || $file == '..') {
continue;
}
<?php
if($handle = opendir($dir)){
while($file = readdir($handle)){
if(is_dir($file) && $file !== '.' && $file !== '..'){
echo "$file<br />";
}
}
}
?>
