I am trying to convert the following to ASP.NET C#
<?php
/* Configuration Start */
$thumb_directory = 'img/thumbs';
$orig_directory = 'img/original';
$stage_width=600; // How big is the area the images are scattered on
$stage_height=400;
/* Configuration end */
$allowed_types=array('jpg','jpeg','gif','png');
$file_parts=array();
$ext='';
$title='';
$i=0;
/* Opening the thumbnail directory and looping through all the thumbs: */
$dir_handle = #opendir($thumb_directory) or die("There is an error with your image directory!");
$i=1;
while ($file = readdir($dir_handle))
{
/* Skipping the system files: */
if($file=='.' || $file == '..') continue;
$file_parts = explode('.',$file);
$ext = strtolower(array_pop($file_parts));
/* Using the file name (withouth the extension) as a image title: */
$title = implode('.',$file_parts);
$title = htmlspecialchars($title);
/* If the file extension is allowed: */
if(in_array($ext,$allowed_types))
{
/* Generating random values for the position and rotation: */
$left=rand(0,$stage_width);
$top=rand(0,400);
$rot = rand(-40,40);
if($top>$stage_height-130 && $left > $stage_width-230)
{
/* Prevent the images from hiding the drop box */
$top-=120+130;
$left-=230;
}
/* Outputting each image: */
echo '
<div id="pic-'.($i++).'" class="pic" style="top:'.$top.'px;left:'.$left.'px;background:url('.$thumb_directory.'/'.$file.') no-repeat 50% 50%; -moz-transform:rotate('.$rot.'deg); -webkit-transform:rotate('.$rot.'deg);">
<a class="fancybox" rel="fncbx" href="'.$orig_directory.'/'.$file.'" target="_blank">'.$title.'</a>
</div>';
}
}
/* Closing the directory */
closedir($dir_handle);
?>
In ASP.NET how do i loop through a series of images from a directory?
What does "explode" mean in PHP?
Is this a do while loop?

I have written these scripts to delete files (image, in fact) in a directory but have the choice to decide which one to delete and view before hand. The view.php script seems to be working fine, however the delete.php doesn't seem to be functioning because the images are not removing.
here are the scripts:
view.php
<?php
$path = '../product-uploads/gloves/'; // path for each page
$files = glob("{$path}*.*"); // Get the files
$files = array_filter($files, 'is_file'); // Get rid of directories
$dates = array_map('filectime', $files); // Get the creation times.
$md5s = array();
array_multisort($dates, $files, SORT_NUMERIC); // in order of creation
foreach ($files AS $file)
{
$hash = md5_file($file);
if (!in_array($hash, $md5s))
{
$md5s[] = $hash;
echo "<img src=\"$file\" /> <br />
<form action=\"delete.php\" method=\"post\">
<input type=\"hidden\" name=\"Name\" value=\"$file\">
<input type=\"submit\" value=\"Delete\">
</form>";
}
}
?>
delete.php
<?php
$path = '../product-uploads/gloves/';// images are here
$Name = $_POST['Name'];
$PathFile = $path.$Name;
$PathFile = basename($PathFile);
header('Location: view.php');
?>
This is because you don't remove the images in your delete.php
Use unlink on pathfile.

I found this awesome code to create a ZIP file using PHP via this link compress/archive folder using php script
<?php
// Config Vars
$sourcefolder = "./" ; // Default: "./"
$zipfilename = "myarchive.zip"; // Default: "myarchive.zip"
$timeout = 5000 ; // Default: 5000
// instantate an iterator (before creating the zip archive, just
// in case the zip file is created inside the source folder)
// and traverse the directory to get the file list.
$dirlist = new RecursiveDirectoryIterator($sourcefolder);
$filelist = new RecursiveIteratorIterator($dirlist);
// set script timeout value
ini_set('max_execution_time', $timeout);
// instantate object
$zip = new ZipArchive();
// create and open the archive
if ($zip->open("$zipfilename", ZipArchive::CREATE) !== TRUE) {
die ("Could not open archive");
}
// add each file in the file list to the archive
foreach ($filelist as $key=>$value) {
$zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
}
// close the archive
$zip->close();
echo "Archive ". $zipfilename . " created successfully.";
// And provide download link ?>
<a href="http:<?php echo $zipfilename;?>" target="_blank">
Download <?php echo $zipfilename?></a>
I would like to create the zip in a particular directory.
$zipfilename = "/path/to/my/zip/folder/myarchive.zip";
Simply make sure the folder is writable.

I am currently making a website where you can upload and download files like a cloud server or something of that sort. I was just wondering what happens if i dont have space on a Hard drive how would i tell PHP to upload to upload to a different hard drive and just stuff like that?
i have this code and i will be adding security but right now im testing:
<?php
set_time_limit(30000);
session_start();
include('../Connect/Connect.php');
$User = $_SESSION['User'];
$Get = 'SELECT * FROM Users WHERE Username = "'.$User.'"';
$Files = $_FILES['File'];
if(isset($User))
{
if(!empty($Files))
{
if($Result = $Connect->query($Get))
{
while($Row = $Result->fetch_assoc())
{
$Limit = $Row['Limit'];
for($X = 0; $X < count($Files['name']); $X++)
{
$Name = $Files['name'][$X];
$TMP = $Files['tmp_name'][$X];
move_uploaded_file($TMP, '../Users/' . $User . '/' . $Name);
}
}
}
}
}
else
{
header("location:../");
}
header("location:index.php");
$Connect->close();
?>
You could always use disk_free_space() before you try to upload/move files. Also, move_uploaded_file will probably return false, but that can be also because of other issues such as permissions.

I want to make picture upload system with php and i want users will be able to upload just
png,jpg files and not viruses or other files. how can i do this?
($_FILES["file"]["type"] == "image/png")
for more information about this click here
step 1: Check the extension (extension file ends with)
step 2: Check the MIME type ($file_info = getimagesize($_FILES['image_file']; $file_mime = $file_info['mime'];)
only allow the those image extension which you want to upload , for that you can make the white list
try something like
$whitelist = array(".jpeg",".jpg",".png");
foreach ($whitelist as $item)
{
if(preg_match("/$item\$/i", $_FILES['uploadfile']['name']))
{
$uploaddir='uploads/uploads_image/';
$uploadfilename=mysql_prep(basename($_FILES['uploadfile']['name']));
$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
$iv= mcrypt_create_iv($iv_size,MCRYPT_DEV_RANDOM);
$newname= mcrypt_encrypt(MCRYPT_RIJNDAEL_256, "this is the key",$uploadfilename.time(), MCRYPT_MODE_ECB, $iv);
$newfilename= (bin2hex($newname));
$uploadfile=$uploaddir.$newfilename.".png";
$access=true;
}
}
you can also block the ip of the user if user try to upload miscellaneous file by making the black list
foreach ($blacklist as $item)
{
if(preg_match("/$item\$/i", $_FILES['uploadfile']['name']))
{
$network = ip2long("10.12.0.0");
$mask = ip2long("255.255.0.0");
$ip = ip2long($_SERVER{'REMOTE_HOST'});
if (($network & $mask) == ($ip & $mask)) {
die("Unauthorized");
}
}
}
1st check:-
//check if contain php and kill it
$pos = strpos($filename,'php');
if(!($pos === false)) {
die('error');
}
2nd check:-
//get the file ext
$file_ext = strrchr($filename, '.');
$image_list = array(".jpg",".jpeg",".gif",".png");
if (!(in_array($file_ext, $image_list))) {
die('not allowed extension,please upload images only');
}
3rd check:-
$fileType = $_FILES["uploaded_file"]["type==image/jpeg || image/gif || image/png"];
4th check:-
preg_match("/.(gif|jpg|png)$/i", $fileName);
hope these checks solve your problem....

On my website, I have an upload story feature with a user written title and story. It uploads it as a text file in a directory. Is there a way to list the content of these files using php or anything? Also, I'd like to only show like 200 chars of the story, and have a 'show full story' button, that would show the full story (I'll use jQuery for this).
Thanks!
$dataArray = array();
//Number of chars for the string
$num = 200;
//Check if DIR exists
if ($handle = opendir('.')) {
//Loop over the directory
while (false !== ($file = readdir($handle))) {
//Strip out the . and .. files
if ($file != "." && $entry != "..") {
$dataArray[] = array();
//Store file contents
$filecontent = file_get_contents($file);
//Split the content and store in array
$length = strlen($filecontent);
$dataArray[] = array(substr($filecontent, 0, $num), substr($filecontent, $num, $length ));
}
}
//close the dir
closedir($handle);
}
With this you get an array with all the content of your .txt files, splittet into 2 Strings, one with 200 chars the other with the rest.
The string with 200 length is $dataArray[x][0] and the other is $dataArray[x][1].
Now you can use this in HTML:
<?php foreach($dataArray as $data) { ?>
<div class="visible">
<?php echo $data[0]; ?>
</div>
<div class="hidden">
<?php echo $data[1]; ?>
</div>
<?php } ?>
in php.net:
to open a directory:
opendir() http://php.net/manual/en/function.opendir.php
$dir = opendir('/path/to/files');
to read the directory (you can loop):
readdir() http://www.php.net/manual/en/function.readdir.php
while (false !== ($file= readdir($dir))) {
//$file has the filename
}
to get the content of a file:
file_get_contents() http://php.net/manual/es/function.file-get-contents.php
$content=file_get_contents($file);
