i creating file manager in cakephp 2.x, i need to showing tree list of '/uploads/' directory and sub-directories.
i have the below code in classic PHP
//show recursive directory tree
function print_tree($dir = '.') {
global $root_path;
echo '<ul class="dirlist">';
$d = opendir($dir);
while($f = readdir($d)) {
if(strpos($f, '.') === 0) continue;
$ff = $dir . '/' . $f;
if(is_dir($ff)) {
echo '<li>' . $f . '';
print_tree($ff);
echo '</li>';
}
}
echo '</ul>';
}
but i need cakephp version of the top code

using awesome jquery File Tree and needed to modify the php code but not getting much luck.
Below is the code and what I am looking for is once I am at file level, how can I PWD to get complete path? I don't think it is possible as I naively thought I could just store previous found value to variable(but guess the way this thing gets called, they call this php completely so variable never retains.. Any other idea?
$_POST['dir'] = urldecode($_POST['dir']);
if( file_exists($root . $_POST['dir']) ) {
$files = scandir($root . $_POST['dir']);
natcasesort($files);
if( count($files) > 2 ) { /* The 2 accounts for . and .. */
echo "<ul class=\"jqueryFileTree\" style=\"display: none;\">";
// All dirs
foreach( $files as $file ) {
if( file_exists($root . $_POST['dir'] . $file) && $file != '.' && $file != '..' && is_dir($root . $_POST['dir'] . $file) ) {
echo "<li class=\"directory collapsed\">" . htmlentities($file) . "</li>";
}
}
// 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>";
}
}
echo "</ul>";
}
}
Okay, I've been searching for a way to list directories and files, which I've figured out and am utilizing code I found here on StackOverflow (Listing all the folders subfolders and files in a directory using php).
So far I've altered code found in one of the answers. I've been able to remove file extensions from both the path and the file name using preg_replace, capitalize the file names using ucwords, and switch out dashes for spaces using str_replace.
What I'm having trouble with now is wrapping the whole thing in a properly nested HTML list. I've managed to set it up so it's wrapped in a list, but it doesn't use nested lists where needed and I can't, for the life of me, figure out how to capitalize the directory names or replace any dashes within the directory name.
So, the questions are, if anyone would be so kind:
How do I wrap the output in properly nested lists?
How do I capitalize directory names while removing the preceding slash and replace dashes or underscores with spaces?
I've left the | within the $ss variable intentionally. I use it as a marker of sorts when I want to throw in characters that will identify where it shows up during trial and error (example $ss = $ss . "<li>workingOrNot").
I'm using:
<?php
$pathLen = 0;
function prePad($level) {
$ss = "";
for ($ii = 0; $ii < $level; $ii++) {
$ss = $ss . "| ";
}
return $ss;
}
function dirScanner($dir, $level, $rootLen) {
global $pathLen;
$filesHidden = array(".", "..", '.htaccess', 'resources', 'browserconfig.xml', 'scripts', 'articles');
if ($handle = opendir($dir)) {
$fileList = array();
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $filesHidden)) {
if (is_dir($dir . "/" . $entry)) {
$fileList[] = "F: " . $dir . "/" . $entry;
}
else {
$fileList[] = "D: " . $dir . "/" . $entry;
}
}
}
closedir($handle);
natsort($fileList);
foreach($fileList as $value) {
$displayName = ucwords ( str_replace("-", " ", substr(preg_replace('/\\.[^.\\s]{3,5}$/', '', $value), $rootLen + 4)));
$filePath = substr($value, 3);
$linkPath = str_replace(" ", "%20", substr(preg_replace('/\\.[^.\\s]{3,5}$/', '', $value), $pathLen + 3));
if (is_dir($filePath)) {
echo prePad($level) . "<li>" . $linkPath . "</li>\n";
dirScanner($filePath, $level + 1, strlen($filePath));
} else {
echo "<li>" . prePad($level) . "" . $displayName . "</li>\n";
}
}
}
}
I feel like these answers should be simple, so maybe I've been staring at it too much the last two days or maybe it has become Frankenstein code.
I'm about out of trial and error and I need help.
foreach($fileList as $value) {
$displayName = ucwords ( str_replace("-", " ", substr(preg_replace('/\\.[^.\\s]{3,5}$/', '', $value), $rootLen + 4)));
$filePath = substr($value, 3);
$linkPath = str_replace(" ", "%20", substr(preg_replace('/\\.[^.\\s]{3,5}$/', '', $value), $pathLen + 3));
if (is_dir($filePath)) {
// Do not close <li> yet, instead, open an <ul>
echo prePad($level) . "<li>" . $linkPath; . "<ul>\n";
dirScanner($filePath, $level + 1, strlen($filePath));
// Close <li> and <ul>
echo "</li></ul>\n";
} else {
echo "<li>" . prePad($level) . "" . $displayName . "</li>\n";
}
}
I guess you're opening the main before call the function and closing it at the end.
I'm newbie about programming, so this is my issue. I am trying to build a recursive php spider usind Simple HTML DOM Parser, crawling into a certain website and returning a list of pages including 2xx, 3xx, 4xx and 5xx. I've been searching several days for a solution but (maybe due to my low experience) I haven't found anything working. My actual code finds all the links on the root/index page, however i would like to be able to find links inside those previously found links recursively and so on, for example to level 5. Assuming the root page is level 0, the recursive function I wrote only shows me level 1 links, repeating them 5 times. Any help appreciated. Thanks.
<?php
echo "<strong><h1>Sitemap</h1></strong><br>";
include_once('simple_html_dom.php');
$url = "http://www.gnet.it/";
$html = new simple_html_dom();
$html->load_file($url);
echo "<strong><h2>Int Links</h2></strong><br>";
foreach($html->find("a") as $a)
{
if((!(preg_match('#^(?:https?|ftp)://.+$#', $a->href)))&&($a->href != null)&&($a->href != "javascript:;")&&($a->href != "#"))
{
echo "<strong>" . $a->href . "</strong><br>";
}
}
echo "<strong><h2>Ext Links</h2></strong><br>";
foreach($html->find("a") as $a)
{
if(((preg_match('#^(?:https?|ftp)://.+$#', $a->href)))&&($a->href != null)&&($a->href != "javascript:;")&&($a->href != "#"))
{
echo "<strong>" . $a->href . "</strong><br>";
}
}
//recursion
$depth = 1;
$maxDepth = 5;
$recurl = "$a->href";
$rechtml = new simple_html_dom();

while($depth <= $maxDepth){
echo "<strong><h2>Link annidati livello $depth</h2></strong><br>";

Try this:
I call this routine in a basic scraper to recursively find all of the links across the site. You'll have to put in some logic to prevent it from crawling external sites that are linked to from pages on your site, else you'll be running forever!
Note, I did get the majority of this code from another SO thread a while back, so the answers are out there.
function crawl_page($url, $depth = 2){
// strip trailing slash from URL
if(substr($url, -1) == '/') {
$url= substr($url, 0, -1);
}
// which URLs have we already crawled?
static $seen = array();
if (isset($seen[$url]) || $depth === 0) {
return;
}
$seen[$url] = true;
$dom = new DOMDocument('1.0');
#$dom->loadHTMLFile($url);
$anchors = $dom->getElementsByTagName('a');
foreach ($anchors as $element) {
$href = $element->getAttribute('href');
if (0 !== strpos($href, 'http')) {
// build the URLs to the same standard - with http:// etc
$path = '/' . ltrim($href, '/');
if (extension_loaded('http')) {
$href = http_build_url($url, array('path' => $path));
} else {
$parts = parse_url($url);
$href = $parts['scheme'] . '://';
if (isset($parts['user']) && isset($parts['pass'])) {
$href .= $parts['user'] . ':' . $parts['pass'] . '#';
}
$href .= $parts['host'];
if (isset($parts['port'])) {
$href .= ':' . $parts['port'];
}
$href .= $path;
}
}
crawl_page($href, $depth - 1);
}
// pull out the actual page name without any parent dirs
$pos = strrpos($url, '/');
$slug = $pos === false ? "root" : substr($url, $pos + 1);
echo "slug:" . $slug . "<br>";
}
The following code counts the number of files inside a folder.
<?php
function folderlist(){
$directoryist = array();
$startdir = './';
//get all image files with a .jpg extension.
$ignoredDirectory[] = '.';
$ignoredDirectory[] = '..';
if (is_dir($startdir)){
if ($dh = opendir($startdir)){
while (($folder = readdir($dh)) !== false){
if (!(array_search($folder,$ignoredDirectory) > -1)){
if (filetype($startdir . $folder) == "dir"){
$directorylist[$startdir . $folder]['name'] = $folder;
$directorylist[$startdir . $folder]['path'] = $startdir;
}
}
}
closedir($dh);
}
}
return($directorylist);
}
$folders = folderlist();
$total_files = 0;
foreach ($folders as $folder){
$path = $folder['path'];
$name = $folder['name'];
$count = iterator_count(new DirectoryIterator($path . $name));
$total_files += $count;
echo '<li>';
echo '<a href="' .$path .'index.php?album=' .$name . '" class="style1">';
echo '<strong>' . $name . '</strong>';
echo ' (' . $count . ' files found)';
echo '</a>';
echo '</li>';
}
echo "Total Files:". $total_files;
?>
However for some reason the count is off by 2. I have a folder with 13 files but this code returns count as 15. For an empty folder, this returns a count of 2.
Can someone point to me the issue with the above snippet?
I'm doing it with DirectoryIterator
$files_in_directory = new DirectoryIterator($path_to_folder);
$c = 0;
foreach($files_in_directory as $file)
{
// We want only files
if($file->isDot()) continue;
if($file->isDir()) continue;
$c++;
}
var_dump($c);
For use as function :
function folderlist($directories = array(), $extensions = array())
{
if(empty($directories))
return false;
$result = array();
$total_count = 0;
foreach($directories as $directory)
{
$files_in_directory = new DirectoryIterator($directory);
$c = 0;
foreach($files_in_directory as $file)
{
// We want only files
if($file->isDot()) continue;
if($file->isDir()) continue;
// This is for php < 5.3.6
$file_extension = pathinfo($file->getFilename(), PATHINFO_EXTENSION);
// If you have php >= 5.3.6 you can use following instead
// $file_extension = $fileinfo->getExtension()
if(in_array($file_extension, $extensions)){
$c++;
$result['directories'][$directory]['files'][$c]['name'] = $file->getFilename();
$result['directories'][$directory]['files'][$c]['path'] = $file->getPath();
$result['directories'][$directory]['count'] = $c;
}
}
$total_count += $c;
}
$result['total_count'] = $total_count;
return $result;
}
Displaying results based on GET superglobal:
if(isset($_GET['album']) && !empty($_GET['album']) && !isset($_GET['listfiles']))
{
// We are in directory view mode
$album = $_GET['album'];
// View all directories and their file count for specified album
$view_directory = folderlist(array($album), array('jpeg', 'jpg', 'log'));
// Loop the folders and display them with file count
foreach ($view_directory['directories'] as $folder_name => $folder_files){
$count = $folder_files['count'];
echo '<li>';
echo '<a href="files.php?album=' . $folder_name . '&listfiles=1" class="style1">';
echo '<strong>' . basename($folder_name) . '</strong>';
echo ' (' . $count . ' files found)';
echo '</a>';
echo '</li>';
}
echo "Total Files:". $get_dir_info['total_count'];
}
elseif(isset($_GET['album'], $_GET['listfiles']) && !empty($_GET['album']))
{
// We are in file view mode for folder
$album = $_GET['album'];
// View all files in directory
$view_files = folderlist(array($album), array('jpeg', 'jpg', 'log'));
echo 'Showing folder content of: <b>'.basename($album).'</b>';
foreach($view_files['directories'][$album]['files'] as $file)
{
$path = $file['path'];
$name = $file['name'];
echo '<li>';
echo '<a href="files.php?file=' . $name . '&path=' . $path . '" class="style1">';
echo '<strong>' . $name . '</strong>';
echo '</a>';
echo '</li>';
}
}
This line is still returning the '.' and '..' vars.
if (!(array_search($folder,$ignoredDirectory) > -1))
see: http://php.net/manual/en/language.types.boolean.php
Try
if (!array_search($folder,$ignoredDirectory))
EDIT:
Also change this:
$ignoredDirectory[] = '.';
$ignoredDirectory[] = '..';
to
$ignoredDirectory = array( '.', '..' );
how can i get image path on server using "browse" button in a html form, select the file (double clicking the file returning its full path), and put the result image path into variable $img_path?
let's say the image dir in my server is /images, i'd like to get path of "foo.jpg", the full image path should be "/images/foo.jpg"
so, all i have to do is :
1. create form which contain "browse" button or something like that - that allow me to explore "images" directory at my server
2. exploring "images" dir, all files listed and clickable, locate "foo.jpg", select it, and voila, i get the image path "/images/foo.jpg"
any lil' help would be appreciated..
Thanks
#CodeCaster thanks for your respond.. but this is all i want (at least closer) :
<?php
$dir = '/images';
if (!isset($_POST['submit'])) {
if ($dp = opendir($dir)) {
$files = array();
while (($file = readdir($dp)) !== false) {
if (!is_dir($dir . $file)) {
$files[] = $file;
}
}
closedir($dp);
} else {
exit('Directory not opened.');
}
if ($files) {
echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';
foreach ($files as $file) {
echo '<input type="checkbox" name="files[]" value="' . $file . '" /> ' .
$file . '<br />';
}
echo '<input type="submit" name="submit" value="submit" />' .
'</form>';
} else {
exit('No files found.');
}
} else {
if (isset($_POST['files'])) {
foreach ($_POST['files'] as $value) {
echo $dir . $value . '<br />';
}
} else {
exit('No files selected');
}
}
?>
using "dir" you can achieve your goal.
<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
echo $entry."\n";
}
$d->close();
?>
You could use dir:
echo "<ul>";
$d = dir("images");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
echo "<li>" . $entry . "</li>";
}
$d->close();
echo "</ul>";
