PHP code, remove renaming - php

If possible please i'd ask a favor, i've been trying to change this it but i haven't succeeded, i wanted to change it in my php file, but no result!
now this script below is a resize script, but it renames my file... i don't need it to do so, can you please see it and tell me how to remove the renaming of the file?
I know it has something to do with : $image->createFile(md5($tempFile)); i tried removing the md5 and still nothing...
Thanks!

You confuse the file's actual name ($_FILES['Filedata']['name']) with the temporary name ($_FILES['Filedata']['tmp_name']). The first is the file the client uploaded. The second is a temporary file that the server created one the server's machine. So you have to use the actual, client-side name here.

This will make your day
$image->createFile(preg_replace("/\.[^\.]*$/", "", $targetFile));

Error while creating thumbnail in php for multiple image upload

I use following code to upload, rename, compress, create thumbnail everything works fine, And recently i noticed while creating thumb it creates fresh copy of thumb images for previously uploaded images also(create thumbnail for uploaded and uploading images too)
Problem:
When form is submitted it crates thumb for uploading image and uploaded images(image file that are present in older).
how do i solve this problem

Bounty Edit
if there is any good and faster function to do please.
all i need is to upload, rename, compress, create thumbnail and save name to DB
The code is need much more optimization. you are iterating the file folder again every time instead of looping the just uploaded files.

As part of your question you asked if there was "any good and faster function to do please."
https://github.com/delboy1978uk/image
Try this! (install via Composer or just require each of the classes in if you just drop the code in yourself)
<?php
use Del\Image;
$image = new Image('/path/to/your.jpg'); //or gif , etc
// Or...
$image = new Image();
$image->load('/path/to/my.png');
You'll then have all of these commands at your disposal:
$image->crop($width, $height, 'center'); // Crops the image, also accepts left or right as 3rd arg
$image->destroy(); // remove loaded image in the class. Frees up any memory
$image->getHeader(); // returns image/jpeg or equivalent
$image->getHeight(); // returns height in pixels
$image->getWidth(); // returns width in pixels
$image->output(); // output to browser
$image->output(true); // passing true returns raw image data string
$image->resize($width, $height); // resize to the given dimensions
$image->resizeAndCrop($width, $height); // resize to the given dimensions, cropping top/bottom or sides
$image->save(); // Save the image
$image->save('/path/to/save.jpg', $permissions, $compression); // Save as a different image
$image->scale(50); // Scale image to a percentage
Loop through your POSTed uploads, load them up, save the original, resize the image, and save the thumbnail. Existing images shouldn't be touched.
There are plenty bad php-programming-habits in that code (e.g. use of eval and general data-flow).
To break it down: The script first validates the uploaded files and moves them to a temp directory. Then it calculates thumbnails for all files in the temp directory.
To change that we use an array which contains the filenames of uploading images.
// ...
$file_type = array();
$ext = '';
$title = '';
$i = 0;
// First change:
$validFileNames = array_column($uploadedFiles, 0);
while ($file_name = readdir($dir_handle)) {
if ($file_name == '.' || $file_name == '..' || !in_array($file_name, $validFileNames)) {
continue;
}
// Nothing changed beyond this point
$file_type = \explode('.', $file_name);
$ext = strtolower(array_pop($file_type));
$title1 = implode('.', $file_type);
$title = htmlspecialchars($title1);
// ...
}
array_column($uploadedFiles, 0) reads the index 0 of every entry in $uploadedFiles, which contains the filename. So $validFileNames contains only filenames of uploading images.
We then check for every file in the temp-directory if its name is included in $uploadedFiles. If not then it was not uploading and can be ignored.
As for the request of a more general optimization:
<?php
$desired_dir = $_SERVER['DOCUMENT_ROOT'].'/upload/file/';
if (!empty($_POST)) {
if (isset($_FILES['files'])) {
$uploadedFiles = array();

how to resize the uploading image and moving to a folder

This your function which is put in your function file
that function has make Folder in the thumbnails in the image folder when you call the function file.
Following way to call the function when image display.
<?php echo img('pages/sample_image.jpg', 122, 81, TRUE) ?>
Here the first is path of the image and 122:means width and 81:height and True/false True:crop the image and false: only resize the image.
And define the Uploadroot in your config file this path for the image folder.
Hope this works.
Thanks.
For resizing an image in php you can use Imagick::resizeImage from this article or use this article
Of course we can use Gd library which has low overhead by recommendation of #CD001. You can find explanation of GD re sizing in this article
Edit for More Explanation
for using Imagick::resizeImage you should see this description
here is the prototype of the function:
bool Imagick::resizeImage ( int $columns , int $rows , int $filter , float $blur [, bool $bestfit = false ] )
Parameters
columns
Width of the image
rows
Height of the image
filter
Refer to the list of filter constants.
blur
The blur factor where > 1 is blurry, < 1 is sharp.
bestfit
Optional fit parameter.
If you want to use gd library here is simple source code
<?php
// File and new size
//the original image has 800x600
$filename = 'images/picture.jpg';
//the resize will be a percent of the original size
$percent = 0.5;
// Content type
header('Content-Type: image/jpeg');
// Get new sizes
list($width, $height) = getimagesize($filename);
$newwidth = $width * $percent;
$newheight = $height * $percent;
// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);
// Resize
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
// Output and free memory
//the resized image will be 400x300
imagejpeg($thumb);
imagedestroy($thumb);

How can i upload file with rename?

I have a file uploading code. everything is ok but i want to rename the file when it up loaded. my code is here. i need only the rename function and where it should be put. this code is very long because there crop the big image to small.
example: if file is 10MB it will be 40 or 50 KB
error_reporting(0);
$change = "";
$abc = "";
define("MAX_SIZE", "400");
function getExtension($str) {
$i = strrpos($str, ".");
if (!$i) {
return "";
} $l = strlen($str) - $i;
$ext = substr($str, $i + 1, $l);
return $ext;
}
$errors = 0;
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$image = $_FILES["file"]["name"];
$uploadedfile = $_FILES['file']['tmp_name'];
if ($image) {
$filename = stripslashes($_FILES['file']['name']);
$extension = getExtension($filename);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) {
$change = '<div class="msgdiv">Unknown Image extension</div>';
$errors = 1;
} else {
$size = filesize($_FILES['file']['tmp_name']);
if ($size > MAX_SIZE * 1024) {
$change = '<div class="msgdiv">You have exceeded the size limit!</div>';
$errors = 1;
} if ($extension == "jpg" || $extension == "jpeg") {
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
} else if ($extension == "png") {
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
} else {
$src = imagecreatefromgif($uploadedfile);
} echo $scr;
list($width, $height) = getimagesize($uploadedfile);
$newwidth = 280;
$newheight = ($height / $width) * $newwidth;
$tmp = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($tmp, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
$filename = "../adimages/" . $_FILES['file']['name'];
imagejpeg($tmp, $filename, 100);
imagedestroy($src);
imagedestroy($tmp);
imagedestroy($tmp1);
}
}
}
Just use the name you want instead of $_FILES['file']['name']
For example:
$filename = "../adimages/". time();
This will name each uploaded file with the current timestamp.
change Your below line
$filename = "../adimages/" . $_FILES['file']['name'];
with the below:-
$new_name = "new_file_name".time();
$filename = "../adimages/" . $new_name;
time() is added for uniqueness. and at the place of new_file_name , You can also put $_FILES['file']['name'];
try this --
just replace your line
$filename = "../adimages/" . $_FILES['file']['name'];
with this new line
$filename = "../adimages/" .time().'.'.$extension ;

Upload image with thumbnail and original picture

I've been using this script to upload pictures on my website for a year now and I finally realised that changes has to be done. I've been looking all over the internet but have not yet found any proper solution, so I've come to you.
This script is currently creating and moving a thumb image into the folder '/images' with the propereties 111x111.
I want it to also upload the original picture, how do I do that?
if(isset($_POST['submit'])) {
if (($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg" || $_FILES["image"]["type"] == "image/gif" || $_FILES["image"]["type"] == "image/x-png") && ($_FILES["image"]["size"] < 4000000))
$current_img=$_FILES['image']['name'];
$extension = substr(strrchr($current_img, '.'), 1);
date_default_timezone_set("Europe/Stockholm");
$time = date("fYhis");
$new_image = uniqid() . $time;
$destination = "images/".$new_image . "-thumb" . "." . $extension;
$action = move_uploaded_file($_FILES['image']['tmp_name'], $destination);
$max_upload_width = 111;
$max_upload_height = 111;
if($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg"){
$image_source = imagecreatefromjpeg($destination) ;
}
if($_FILES["image"]["type"] == "image/gif"){
$image_source = imagecreatefromgif($_FILES["image"]["tmp_name"]);
}
if($_FILES["image"]["type"] == "image/bmp"){
$image_source = imagecreatefromwbmp($_FILES["image"]["tmp_name"]);
}
if($_FILES["image"]["type"] == "image/x-png"){
$image_source = imagecreatefrompng($_FILES["image"]["tmp_name"]);
}
imagejpeg($image_source,$destination,100);
chmod($destination,0644);
list($image_width, $image_height) = getimagesize($destination);
if($image_width>$max_upload_width || $image_height >$max_upload_height){
$proportions = 1;
if($image_width>$image_height){
$new_width = $max_upload_width;
$new_height = round($max_upload_width/$proportions);
}
else{
$new_height = $max_upload_height;
$new_width = round($max_upload_height*$proportions);
}
$new_image = imagecreatetruecolor($new_width , $new_height);
$image_source = imagecreatefromjpeg($destination);
imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height);
imagejpeg($new_image, $destination, 100); // save
imagedestroy($new_image);
}
Just upload the file into a different directory by using following code
$originalImage = "images/".$new_image . "-ImageName" . "." . $extension;
$action = move_uploaded_file($_FILES['image']['tmp_name'], $originalImage)
;
And use $originalImage instead of $_FILES['image']['tmp_name'] in creating thumbnail.
Check by applying the following code
if(isset($_POST['submit'])) {
if (($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg" || $_FILES["image"]["type"] == "image/gif" || $_FILES["image"]["type"] == "image/x-png") && ($_FILES["image"]["size"] < 4000000))
$current_img=$_FILES['image']['name'];
$extension = substr(strrchr($current_img, '.'), 1);
date_default_timezone_set("Europe/Stockholm");
$time = date("fYhis");
$new_image = uniqid() . $time;
$originalImage = "images/".$new_image . "-ImageName" . "." . $extension;
$destination = "images/".$new_image . "-thumb" . "." . $extension;
$action = move_uploaded_file($_FILES['image']['tmp_name'], $originalImage);
$max_upload_width = 111;
$max_upload_height = 111;
if($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg"){
$image_source = imagecreatefromjpeg($originalImage) ;
}
if($_FILES["image"]["type"] == "image/gif"){
$image_source = imagecreatefromgif($originalImage);
}
if($_FILES["image"]["type"] == "image/bmp"){
$image_source = imagecreatefromwbmp($originalImage);
}
if($_FILES["image"]["type"] == "image/x-png"){
$image_source = imagecreatefrompng($originalImage);
}
imagejpeg($image_source,$destination,100);
chmod($destination,0644);
list($image_width, $image_height) = getimagesize($destination);
if($image_width>$max_upload_width || $image_height >$max_upload_height){
$proportions = 1;
if($image_width>$image_height){
$new_width = $max_upload_width;
$new_height = round($max_upload_width/$proportions);
}
else{
$new_height = $max_upload_height;
$new_width = round($max_upload_height*$proportions);
}
$new_image = imagecreatetruecolor($new_width , $new_height);
$image_source = imagecreatefromjpeg($destination);
imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height);
imagejpeg($new_image, $destination, 100); // save
imagedestroy($new_image);
}

Remove extension when creating a new image from resizing

i have this code, which i kind of modified a little bit ago.. my problem is that this creates a new thumbnail of the image i upload but it adds a .PNG,.JPEG etc etc extension which i don't need! now, my problem is that if i try to remove from the function the extensions it won't let me create the new image...
What i mean is that if i remove : '.'.$this->ext from the createFile function it won't create the file anymore...
Here is the code... it seems to be a little long but it isn't..
if (!empty($_FILES)) {
function setFile($src = null) {
$this->ext = strtoupper(pathinfo($src, PATHINFO_EXTENSION));
if(is_file($src) && ($this->ext == "JPG" OR $this->ext == "JPEG")) {
$this->img_r = ImageCreateFromJPEG($src);
} elseif(is_file($src) && $this->ext == "PNG") {
$this->img_r = ImageCreateFromPNG($src);
} elseif(is_file($src) && $this->ext == "GIF") {
$this->img_r = ImageCreateFromGIF($src);
}
$this->img_w = imagesx($this->img_r);
$this->img_h = imagesy($this->img_r);
}
function resize($largestSide = 100) {
$width = imagesx($this->img_r);
$height = imagesy($this->img_r);
$newWidth = 0;
$newHeight = 0;
if ($width > $height) {
$newWidth = $largestSide;
$newHeight = $height * ($newWidth / $width);
} else {
$newHeight = $largestSide;
$newWidth = $width * ($newHeight / $height);
}
$this->dst_r = ImageCreateTrueColor($newWidth, $newHeight);
imagecopyresampled($this->dst_r, $this->img_r, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
$this->img_r = $this->dst_r;
$this->img_h = $newHeight;
$this->img_w = $newWidth;
}
function createFile($output_filename = null) {
if ($this->ext == "JPG" OR $this->ext == "JPEG") {
imageJPEG($this->dst_r, $this->uploaddir.$output_filename.'.'.$this->ext, $this->quality);
} elseif($this->ext == "PNG") {
imagePNG($this->dst_r, $this->uploaddir.$output_filename.'.'.$this->ext);
} elseif($this->ext == "GIF") {
imageGIF($this->dst_r, $this->uploaddir.$output_filename.'.'.$this->ext);
}
$this->output = $this->uploaddir.$output_filename.'.'.$this->ext;
}
function setUploadDir($dirname) {
$this->uploaddir = $dirname;
}
function flush() {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];
imagedestroy($this->dst_r);
unlink($targetFile);
imagedestroy($this->img_r);
}
}
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];
move_uploaded_file ($tempFile, $targetFile);
$image = new Image();
$image->setFile($targetFile);
$image->setUploadDir($targetPath);
$image->resize(800);
$image->createFile($_FILES['Filedata']['name']);
$image->flush();
}
After formatting your code and removing the extra close-curly at the end (while moving your function definitions outside of your if statement), your code should look something like this:
<?php
function setFile($src = null) {
$this->ext = strtoupper(pathinfo($src, PATHINFO_EXTENSION));
if (is_file($src) && ($this->ext == "JPG" OR $this->ext == "JPEG")) {
$this->img_r = ImageCreateFromJPEG($src);
} elseif (is_file($src) && $this->ext == "PNG") {
$this->img_r = ImageCreateFromPNG($src);
} elseif (is_file($src) && $this->ext == "GIF") {
$this->img_r = ImageCreateFromGIF($src);
}
$this->img_w = imagesx($this->img_r);
$this->img_h = imagesy($this->img_r);
}
function resize($largestSide = 100) {
$width = imagesx($this->img_r);
$height = imagesy($this->img_r);
$newWidth = 0;
$newHeight = 0;
if ($width > $height) {
$newWidth = $largestSide;
$newHeight = $height * ($newWidth / $width);
} else {
$newHeight = $largestSide;
$newWidth = $width * ($newHeight / $height);
}
$this->dst_r = ImageCreateTrueColor($newWidth, $newHeight);
imagecopyresampled($this->dst_r, $this->img_r, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
$this->img_r = $this->dst_r;
$this->img_h = $newHeight;
$this->img_w = $newWidth;
}
function createFile($output_filename = null) {
if ($this->ext == "JPG" OR $this->ext == "JPEG") {
imageJPEG($this->dst_r, $this->uploaddir . $output_filename . '.' . $this->ext, $this->quality);
} elseif ($this->ext == "PNG") {
imagePNG($this->dst_r, $this->uploaddir . $output_filename . '.' . $this->ext);
} elseif ($this->ext == "GIF") {
imageGIF($this->dst_r, $this->uploaddir . $output_filename . '.' . $this->ext);
}
$this->output = $this->uploaddir . $output_filename . '.' . $this->ext;
}
function setUploadDir($dirname) {
$this->uploaddir = $dirname;
}
function flush() {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//', '/', $targetPath) . $_FILES['Filedata']['name'];
imagedestroy($this->dst_r);
unlink($targetFile);
imagedestroy($this->img_r);
}
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//', '/', $targetPath) . $_FILES['Filedata']['name'];
move_uploaded_file($tempFile, $targetFile);
$image = new Image();
$image->setFile($targetFile);
$image->setUploadDir($targetPath);
$image->resize(800);
$image->createFile($_FILES['Filedata']['name']);
$image->flush();
}
This still will not work because you're calling these methods as though they're member functions of an Image object which isn't defined anywhere. Take a look at Objects and Classes in the PHP manual.
