imagecreatefromjpeg makes same files (multiple images) - php

I'm trying to send a formData object from jquery (ajax) to php. The formData contains image files. I need them to be uploaded and resized (which both used to work). Now the problem is, when I create a imagecreatefromjpeg object in php, it seems like he only takes the 1st image and uses this for the amount of images in the formdata.
foreach($_FILES as $file)
{
$ImageName = $file['name'];
$ImageSize = $file['size'];
$TempSrc = $file['tmp_name'];
$ImageType = $file['type'];
$DestinationDirectory .= $CategoryName . "/";
if (is_array($ImageName))
{
$c = count($ImageName);
for ($i=0; $i < $c; $i++)
{
$processImage = true;
$RandomNumber = rand(0, 9999999999); // We need same random name for both files.
if(!isset($ImageName[$i]) || !is_uploaded_file($TempSrc[$i]))
{
echo '<div class="error">Error occurred while trying to process <strong>'.$ImageName[$i].'</strong>, may be file too big!</div>'; //output error
}
else
{
//Validate file + create image from uploaded file.
switch(strtolower($ImageType[$i]))
{
case 'image/png':
$CreatedImage = imagecreatefrompng($TempSrc[$i]);
break;
case 'image/gif':
$CreatedImage = imagecreatefromgif($TempSrc[$i]);
break;
case 'image/jpeg':
case 'image/pjpeg':
$CreatedImage = imagecreatefromjpeg($TempSrc[$i]);
break;
default:
$processImage = false; //image format is not supported!
} //get Image Size
/*
$outputArr[] = array('image' => $ImageName[$i]);
header('Content-Type: application/json');
echo json_encode($outputArr);
*/
echo $ImageName[$i];
}
}
}
}
So this echoes $i times the same image. Once I remove the switch case, it echoes the correct images...

image extension is not showing in PHP file-upload

I'm using this piece of code to handle an input for uploading multiple images, and resizing them as well. It works but there is one small thing that doesn't want to do its job. The extension that I'm trying to get is not showing up in the file's name.
Here is the piece of code where the problem should be:
if(isset($_POST["submit"])) {
if(is_array($_FILES)) {
foreach ($_FILES['fileToUpload']['tmp_name'] as $uploadedFile) {
//$uploadedFile = $_FILES['fileToUpload']['tmp_name'];
if($uploadedFile <> ''){
$sourceProperties = getimagesize($uploadedFile);
$newFileName = time();
$dirPath = "../images/";
$ext = pathinfo($_FILES['fileToUpload']['name'], PATHINFO_EXTENSION);
$imageType = $sourceProperties[2];
switch ($imageType) {
case IMAGETYPE_PNG:
$imageSrc = imagecreatefrompng($uploadedFile);
$tmp = imageResize($imageSrc,$sourceProperties[0],$sourceProperties[1]);
imagepng($tmp,$dirPath. $newFileName. "_thump.". $ext);
break;
case IMAGETYPE_JPEG:
$imageSrc = imagecreatefromjpeg($uploadedFile);
$tmp = imageResize($imageSrc,$sourceProperties[0],$sourceProperties[1]);
imagejpeg($tmp,$dirPath. $newFileName. "_thump.". $ext);
break;
case IMAGETYPE_GIF:
$imageSrc = imagecreatefromgif($uploadedFile);
$tmp = imageResize($imageSrc,$sourceProperties[0],$sourceProperties[1]);
imagegif($tmp,$dirPath. $newFileName. "_thump.". $ext);
break;
default:
echo "<div class='alert alert-danger'>File is not an image.</div>";
exit;
break;
}
}
}
}
}
For an example, something it is now saving is called 1547265041_thump. in my database.
What is going wrong?
Check $ext getting extension or not.
If it not getting check $_FILES['fileToUpload']['name'] reading or not.
You can debug by echo them.
Check you database character length.
Hope it helps.
The $_FILES['fileToUpload']['name'] seems to be an array, which is logical since you can upload multiple images at once. To loop through, I added a counter to the foreach to output the extension. Now it works well!

Creating thumbnail from an uploaded image in Joomla 2.5

I'm really new to joomla, I don't have idea what should I do to make it done. I just have this kind of code in administrator table, it refers to uploading files.
//Support for file field: cover
if(isset($_FILES['jform']['name']['cover'])):
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.file');
$file = $_FILES['jform'];
//Check if the server found any error.
$fileError = $file['error']['cover'];
$message = '';
if($fileError > 0 && $fileError != 4) {
switch ($fileError) :
case 1:
$message = JText::_( 'File size exceeds allowed by the server');
break;
case 2:
$message = JText::_( 'File size exceeds allowed by the html form');
break;
case 3:
$message = JText::_( 'Partial upload error');
break;
endswitch;
if($message != '') :
JError::raiseWarning(500,$message);
return false;
endif;
}
else if($fileError == 4){
if(isset($array['cover_hidden'])):;
$array['cover'] = $array['cover_hidden'];
endif;
}
else{
//Check for filesize
$fileSize = $file['size']['cover'];
if($fileSize > 10485760):
JError::raiseWarning(500, 'File bigger than 10MB' );
return false;
endif;
//Replace any special characters in the filename
$filename = explode('.',$file['name']['cover']);
$filename[0] = preg_replace("/[^A-Za-z0-9]/i", "-", $filename[0]);
//Add Timestamp MD5 to avoid overwriting
$filename = md5(time()) . '-' . implode('.',$filename);
$uploadPath = JPATH_ADMINISTRATOR.DIRECTORY_SEPARATOR.'components'.DIRECTORY_SEPARATOR.'com_comic'.DIRECTORY_SEPARATOR.'images'.DIRECTORY_SEPARATOR.$filename;
$fileTemp = $file['tmp_name']['cover'];
if(!JFile::exists($uploadPath)):
if (!JFile::upload($fileTemp, $uploadPath)):
JError::raiseWarning(500,'Error moving file');
return false;
endif;
endif;
$array['cover'] = $filename;
}
endif;
I could upload the file (in this case, an image) from the codes above, but what I'll do next is creating a thumbnail for the uploaded image. I searched for the php codes through the internet but it doesn't seem to work since I can't synchronize it into joomla codes. Umm.. I've made a folder named thumbnail in images folder. So what should I do next?
I'll be so happy and grateful if any of you could help me with this. Thanks.
Well i can share technique I'm using, i hope it will help:
In table's method check after the all validation is done (at the end of the method, just before returning true) i add the following code:
$input = JFactory::getApplication()->input;
$files = $input->files->get('jform');
if (!is_null($files) && isset($files['image']))
$this->image = $this->storeImage($files['image']);
The i create a new method called storeImage() :
protected $_thumb = array('max_w' => 200, 'max_h' => 200);
private function storeImage($file) {
jimport('joomla.filesystem.file');
$filename = JFile::makeSafe($file['name']);
$imageSrc = $file['tmp_name'];
$extension = strtolower(JFile::getExt($filename));
// You can add custom images path here
$imagesPath = JPATH_ROOT . '/media/';
if (in_array($extension, array('jpg', 'jpeg', 'png', 'gif'))) {
// Generate random filename
$noExt = rand(1000, 9999) . time() . rand(1000, 9999);
$newFilename = $noExt . '.' . $extension;
$imageDest = $imagesPath . $newFilename;
if (JFile::upload($imageSrc, $imageDest)) {
// Get image size
list($w, $h, $type) = GetImageSize($imageDest);
switch ($extension) {
case 'jpg':
case 'jpeg':
$srcRes = imagecreatefromjpeg($imageDest);
break;
case 'png':
$srcRes = imagecreatefrompng($imageDest);
break;
case 'gif':
$srcRes = imagecreatefromgif($imageDest);
break;
}
// Calculating thumb size
if($w > $h) {
$width_ratio = $this->_thumb['max_w'] / $w;
$new_width = $this->_thumb['max_w'];
$new_height = $h * $width_ratio;
} else {
$height_ratio = $this->_thumb['max_w'] / $h;
$new_width = $w * $height_ratio;
$new_height = $this->_thumb['max_w'];
}
$destRes = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($destRes, $srcRes, 0, 0, 0, 0, $new_width, $new_height, $w, $h);
// Creating resized thumbnail
switch ($extension) {
case 'jpg':
case 'jpeg':
imagejpeg($destRes, $imagesPath . 'thumb_' . $newFilename, 100);
break;
case 'png':
imagepng($destRes, $imagesPath . 'thumb_' . $newFilename, 1);
break;
case 'gif':
imagegif($destRes, $imagesPath . 'thumb_' . $newFilename, 100);
break;
}
imagedestroy($destRes);
// Delete old image if it was set before
if (($this->image != "") && JFile::exists($imagesPath . $this->image)) {
JFile::delete($imagesPath . $this->image);
JFile::delete($imagesPath . 'thumb_' . $this->image);
}
return $newFilename;
}
}
}
}
return null;
}
This method returns uploaded file filename, which table stores in 'image' column. It creates two files, one original image and resized thumb with file prefix '_thumb'.
I hope it helps :)
I used Jimage : https://api.joomla.org/cms-3/classes/JImage.html
$JImage = new JImage($img_path);
$size_thumb = '150x150';
$JImage->createThumbs($size_thumb,1,$path.'/thumb');
Short, simple and efficient.

You switch code makes no sense. Apparently you missed the point of switch/case vs. if and this is wrong:
switch ($imageType) {
case $imageType == "image/gif":
move_uploaded_file($tmpName,$filePathFull);
break;
...
default:
echo 'Wrong image type selected. Only JPG, PNG or GIF formats accepted!.';
}
and should be:
switch ($imageType) {
case "image/gif":
move_uploaded_file($tmpName,$filePathFull);
break;

Renaming Files by adding a Suffix

Can i change the name of the file, say an image for example which has name like '0124.jpg',
before sending it to the server?
<input id="f1" style="margin-bottom: 5px;" type="file" name="f1" onchange="javascript:readURL_f1(this);"/>
<input id="f2" style="margin-bottom: 5px;" type="file" name="f1" onchange="javascript:readURL_f2(this);"/>
If the file is uploaded from f1, then before sending to to server, the name should become pic1_[filename].jpg, instead of just sending the raw filename.
I don't want this to be done in server side because i think it might be complicated.
EDIT : Upload.php is my php file which uploads whatever in the file. So, its been a challenge for me. i can change the filename, but that gets changed in all the three uploads.
for example i add an '_' for the incoming filename. Then, it gets changed to all filenames.
Anyway from clientside?
my upload script: Upload.php
upload.php
<?php mysql_connect('localhost','root','phpmyadmin');
$connected = mysql_select_db('image_Upload');
?>

When you are uploading the File you usually follow this workflow
User Chooses a File and Clicks Upload
Server Pics up the File from the temp folder - check MimeType, Resize and Rename the File and store it to which ever location you want on the file server.
While Renaming if you want to see if the same file name exsists and then append the _01, _02 then you will have to check if a file exists with that name and then append the unique number at the end.
Things like that are usually done in the server side. The purpose of preppending or appending a code or, say, changing the whole name of the file is to prevent uploaded file name conflicts. So imagine doing it to the client side? When upload button is pressed you need to ask the server if this file name is already existing, then you wait for the response of the server then do the renaming based on the response then send it to the server instead of just sending it to the server then do the checking then renaming then saving.

php user image upload create specified folder unique image names

I'm (a newbie in php) still working on a time off project and another problem came up, for which I can't find a solution. Therefore I hope u guys can help me! Worked great the last time I posted something on here! I really appreciate your help...thx ahead!
My problem:
I want users to be able to upload pictures when they are logged in. They got several little buttons on their profile with images on them...and they should be able to change them...
I want to have it like this -> When a user uploads an image, the script shall create a new folder on the server. This shall happen in the "user_images" folder (that exists already). So a user with e.g. "id=55" creates a folder "55" in "user_images" when he uploads images. I tried and tried and tried and tried...with different syntax in line -> "$upload_dir =" but without any success :-/ I just don't get it to work...
Here is the part of the script:
<?php
include 'dbconfig.php';
page_protect();
$rs_settings = mysql_query("select * from user where id='$_SESSION[user_id]'");
while ($row_settings = mysql_fetch_array($rs_settings));
error_reporting (E_ALL ^ E_NOTICE);
session_start();
//only assign a new timestamp if the session variable is empty
if (!isset($_SESSION['user_id']) || strlen($_SESSION['user_id'])==0){
$_SESSION['user_id'] = mysql_query("select * from user where id='$_SESSION[user_id]'");
//assign the timestamp to the session variable
$_SESSION['user_file_ext']= "";
}

It would be really cool if someone could help me to fix these problems...you may know how hard it is, when you're just a rookie! If there's more weird syntax in there...let me know, I'm just a beginner (like we all have been at the beginning) and trying to get better :)
Thank you guys!
Keeping in mind that allowing any user to upload content to your server creates a security hole that requires special attention, this is a bit of code I've used in the past for an internal-use application:
$folderPath = "/uploads/" . $folderName;
$exist = is_dir($folderPath);
if(!$exist) {
mkdir("$folderPath");
chmod("$folderPath", 0755);
}
else { echo "Folder already exists"; }
You can also chmod right from mkdir but was having issues with doing that on this particular server config.
http://php.net/manual/en/function.mkdir.php
UPDATED with more complete example:
// Define path where file will be uploaded to
// User ID is set as directory name
$folderPath = "/uploads/$userID";
// Check to see if directory already exists
$exist = is_dir($folderPath);
// If directory doesn't exist, create directory
if(!$exist) {
mkdir("$folderPath");
chmod("$folderPath", 0755);
}
else { echo "Folder already exists"; }
// PROCESS FILE UPLOAD
// Set initial/temporary upload location
// temp_uploads must have proper read/write permissions (755 or 777)
$target_path = "/uploads/temp_uploads/";
// Append the name of the uploaded file to the temp directory
$target_path .= basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
$filename = basename( $_FILES['uploadedfile']['name']);
// Location where temporary file is being stored
$temp_location = '/uploads/temp_uploads/' . basename( $_FILES['uploadedfile']['name']);
// Final destination where file will be located
$destination = "/uploads/$folderPath/$filename";
rename($temp_location, $destination);
}
You are assigning a mysql query resource to the $_SESSION["user_id"]
$_SESSION['user_id'] = mysql_query("select * from user where id='$_SESSION[user_id]'");
I think you want to get the user id out of that query
Also if your code produces any errors it would be great if you included them in your question
ps. don't use mysql_* functions, they are deprecated and create unwanted security holes if not used properly, learn dibi, pdo, or any other newer database layer
$file_name=basename($_FILES['uploadedfile']['name']);
mkdir("upload/".$username,0777);
$target_path = "upload/$username/". $file_name;
