PHP - Image Script

Hi All
Not so much help as here is a handy class for uploading images
Please feel free to find security bugs and let me know.
Also feel free to use it if you want.

http://onlyican.com/test_samples/bl_upload_img.phps

To use the class, simply use the following

require_once('bl_upload_img.php');
$objUploadImg = new UploadImg();
//Set values here if you wish such as 
$objUploadImg->setFormField('myFormField'); // The Name from <input type="file" name="myFormField" />
$objUploadImg->setSaveDirMain($_SERVER['DOCUMENT_ROOT'].'/MyImageFolder'; //Make sure to set the permissions

//You can change most settings, just look at the function setDetaultValues() to get the function name
//Now upload the image
if($objUploadImg->uploadImage()){
  $strFileName = $objUploadImg->getFileNameMain();

  }else{
  echo 'Error uploading Image<br />'.$objUploadImg->getErrorMessage();

  }

If I upload this script in /www/ads/insert/image/ it works fine
If I upload it in /www/ads/insert/ it does not work It says PHP could not open /new/ to upload image

Code: [Select]
<?

$target_path = 'images/new/';
$image_name = 'myself.gif';

if( imagejpeg( $tmp_img, "{$target_path}{$image_name}" ) ){
print"image uploaded!";
}

?>
I think because PHP only allows to upload images 1 folder deep!!!

Why? How do I solve this? I want to create different folders for each group of images

Me and a friend are working on a nice secure Image Upload Script.

The Upload Class

<?php
class imageUploader
{
public $image; // [name], [type], [tmp_name], [error], [size]

public $maxFileSize;

public $imageExtension;

public function __construct($image, $max_file_size)

$this->image = $image;

$this->maxFileSize = $max_file_size;
}

{
$validExts = array("gif" => "image/gif", "jpeg" => "image/jpeg", "png" => "image/png");

if(in_array(strtolower($this->image["type"]), $validExts) == true)
{
foreach($validExts as $name => $value)
{
if(strtolower($this->image["type"]) == $value)
{
$this->imageExtension = $name;

break;
}
}

return true;
}
else
{
return false;
}
}

public function isValidSize()
{
if($this->image["size"] > $this->maxFileSize)
{
return false;
}
else
{
return true;
}
}

public function uploadImage()
{
if($this->image["error"] > 0)
{
$errors[] = "An error has occurred";
}
elseif($this->isValidImage() == false)
{
$errors[] = "Invalid file type. Only use JPG, GIF or PNG";
}
elseif($this->isValidSize() == false)
{
$errors[] = "Max file size exceeded.";
}

if(count((array) $errors) == 0)
{
move_uploaded_file($this->image["tmp_name"], "Images/" . $this->generateName(rand(10, 15)) . time() . "." . $this->imageExtension);
}
else
{
echo implode("<br />", $errors);
}
}

public function createThumbnails()
{

}

public function resizeImage($size_y, $size_x)
{

}

public function generateName($length)
{
$randstr = "";
        
for ($i = 0; $i < $length; $i++)
{
$randnum = mt_rand(0, 61);
            
if ($randnum < 10)
{
$randstr .= chr($randnum + 48);
}
elseif ($randnum < 36)
{
$randstr .= chr($randnum + 55);
}
else
{
$randstr .= chr($randnum + 61);
}
}
return $randstr;
}
}
?>


The Everyday HTML
Code: [Select]
<form action="" method="post" enctype="multipart/form-data">
<table>
<tr>
<td>Image</td>
<td><input type="file" name="file" id="file" /></td>
<td><input type="submit" name="submit" value="Submit" /></td>
</tr>
</table>
</form>

My friend did most of the work, but had to go to sleep.  My problem is I have a deadline to finish this in under 3 hours for use on my website.

What I need it to do is create thumbnails in a /Thumbnail/ sub-folder, with thumbnails being cropped to 100px x 100px.
If the full image is larger than 600px x 600px they would have to be resized down to nothing more than 600px for the longest side.  I wouldn't mind if they were 300px x 600px, just nothing larger than 600px.

I'm willing to pay for this to be completed, I only have roughly $50 though.  I know this isn't a freelance area, but it kind of suits this area too with a freelance option.

After the upload script is done, I have to work on a php system to get the images and display them, so that I'm not directly linking images.

So anyone got some spare time to help out?

Hi

Im trying to write a script to clean up my image directory which has quite a lot of unused images that have built up over time.
In order to do this I am doing the following.

First Create a database table called 'image_clean' Then I'm searching through 3 tables and collecting all the image file names and dumping the names in the table 'image_clean'

Can do that no problem. So now I have all the images I need in this one table 'image_clean' I now want to go through my directory 'image_uploads' and delete anything thats not in the 'image_clean' table.

I know how to delete the files using unlink Im just unsure how to search through the directory file by file and check the file against the database. Im asumming I need to put them in an array. Could anyone give be a clue or two to get me started.

I have no problem checking a database against a directory but when its the other way round 'checking a directory against a database I'm lost. What I might do is pop the files to delete in a new database called 'image_delete' so that I can then check the images to delete before I write the unlink script. But I'm just not sure how to pick up each file and compare it to the table.

Thanks in advance.

ok i have a image uploading script here, it works fine but theres one thing im unhappy with

when i first downloaded it it had 1 working one, and the rest examples which you basically have to put together yourself with the sample code (doesen't work without adding missing coding), i have done all that then i took the time to add a random string prefix, im new at php so it took me awhile to work out which strings would work in the right area.

now this is what i need help with, when it uploads it has two options, download and remove, these both work fine, but on the file uploader that does work it has "file uploaded to "http://site.com/image.png" the example of course did not work (had loading bar working, and etc but didn't upload or have the feature i just mentioned) and the coder of the script used javascript and inner html for the file uploaded.... etc, because it uploads without refreshing, only thing is i cant seem to get it to work with the new random string i put in, i tried to recreate one with the same type of thing they used for the filename but it didn't work

well here is the code, hope you can help.

and here is the phpuploader.php file just in case

i need help on this one. i am aiming to make my own smaller version of tineye.com or something similar i do have a function that will compare 2 images in GD.


all i have to figure out now is how to spider the default image off of major networking sites like facebook,myspace etc. and list all the results found and the similarity of each picture.

the function is something like


compare_imgs($path,$source_pic,$comparison_pic) { }

Hi Guys,

I have an issue with the following script which is throwing this error

Quote

( ! ) Parse error: syntax error, unexpected end of file in C:\wamp64\www\script\images.php on line 41

I just can not see the error, can anyone help (not even sure the script is going to work)

<?php
/* settings */
//folder for images saving
$saveDir = "c:\wamp64\www\script\images\";

//database connection
// Turn off all error reporting
error_reporting(0);

$conn = mysqli_connect('localhost', 'root', '', 'tbl_temp_products');

//start and end table row to prevent timeout or hard server work
$start = '1';
$end = '200';
/* end of settings */

//query for fetching the image urls
$sql = 'SELECT image_url FROM tbl_temp_products ORDER BY id DESC LIMIT ' . $start . ',' . $end . '';
$res = $conn->query($sql);

$count = 0;          //this is for count the total row fetched
$notify = '';        //this is for seeing result or errors

while ($row = $res->fetch_assoc()) {
$url = $row(['image_url']);
$dest = $saveDir . clean($row(['image_url'])) . '.jpg';

if (!file_exists($dest)){   //prevent file overwriting
   if (copy($url, $dest)){
      $notify.= 'image saved: '. $row(['image_url']);
      $count++;
   }else{
      $notify.= 'ERROR saving image: '. $row(['image_url']);
   }else{
   $notify.= 'image already exists: '. $row(['image_url']);
   }
}
//output result
echo 'TOTAL IMAGE SAVED: ' .$count .'\n';
echo $notify;
?>

 

I'm new to programming so take it easy on me but I wrote this script for php and it's not complete yet but I could use some advice on file upload security. Besides recreating the image, checking token/request and setting apache settings what else can I do to secure this application. Here's my code:

header('Content-Type: application/json');

$uploaded = array();
	
if(!empty($_FILES['file']['name'][0])) {	
	
	$allowedExts = array("gif", "jpeg", "pjpeg", "x-png", "jpg", "png");
		
	foreach ($_FILES['file']['tmp_name'] as $k => $v) {
		$name = $_FILES['file']['name'][$k];
		$type = $_FILES['file']['type'][$k];
		$error = $_FILES["file"]["error"][$k];
		$size = $_FILES["file"]["size"][$k];
	    $tempDir = $_FILES["file"]["tmp_name"][$k];
		$lowerName = strtolower($name);
		$temp = explode(".", $lowerName);
		$extension = end($temp);
		
		if ((($type == "image/gif")
			|| ($type == "image/jpeg")
			|| ($type == "image/jpg")
			|| ($type == "image/pjpeg")
			|| ($type == "image/x-png")
			|| ($type == "image/png"))
			&& ($size < 20000)
			&& in_array($extension, $allowedExts)) {
			if ($error > 0) {
			echo "Return Code: " . $error . "<br>";
			} else {
				$imageInfo = getimagesize($tempDir);
				if($imageInfo['mime'] != 'image/gif' && $imageInfo['mime'] != 'image/jpeg' && $imageInfo['mime'] != 'image/jpg' &&
				$imageInfo['mime'] != 'image/pjpeg' && $imageInfo['mime'] != 'image/x-png' && $imageInfo['mime'] != 'image/png') {
					echo 'Sorry we only accept GIF, JPEG, JPG, PJPEG, X-PNG, PNG image files!';
				}else {
				switch($type) {
					case 'image/gif':
						$newName = md5(uniqid()). '.' .time(). '.gif';
					break;
					case 'image/jpeg':
						$newName = md5(uniqid()). '.' .time(). '.jpeg';
					break;
					case 'image/jpg':
						$newName = md5(uniqid()). '.' .time(). '.jpg';
					break;
					case 'image/pjpeg':
						$newName = md5(uniqid()). '.' .time(). '.pjpeg';
					break;
					case 'image/x-png':
						$newName = md5(uniqid()). '.' .time(). '.x-png';
					break;
					case 'image/png':
						$newName = md5(uniqid()). '.' .time(). '.png';
					break;
				}
				
				
				if (file_exists('images/' .Session::get(Config::get('session/session_name')). '/' .$newName)) {
				   echo escape($name) . " already exists. ";
				} else {
				if(move_uploaded_file($tempDir, 'images/' .Session::get(Config::get('session/session_name')). '/' .$newName)) {
					$uploaded[] = array(
						'name' => $name,
						'file' => 'images/' .Session::get(Config::get('session/session_name')). '/' .$newName
				    );
				}
				}
				}
				}
			} else {
			   echo 'Sorry we only accept GIF, JPEG, JPG, PJPEG, X-PNG, PNG image files!';
			}
		}
	}

 I've been researching apache Mod_mime but can't find enough info to wrap my mind around it.

Hi   Ultimate Aim: To upload multiple images using ajax using a PHP script which will be fired once an image is selected and then return the resulting URL for use in rest of my JS
  http://peter-gosling...hooseimage.html simple form
posts to
http://peter-gosling...d/saveimage.php   This PHP script below currently gets the posted image and assigns it a random number file name and echos this

<?php
header("Access-Control-Allow-Origin: *");

$uploaddir = '/home/petergos/public_html/testupload/images/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
$urlpath = "http://www.peter-gosling.co.uk/testupload/images/";

$temp = explode(".",$_FILES["userfile"]["name"]);
$newfilename = rand(1,999999999) . '.' .end($temp);
$newuploadfile = $uploaddir . $newfilename;
echo "<p>";

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newuploadfile)) {
    $urlfile = $urlpath . $newfilename;
  echo $urlfile;
} else {
   echo "Upload failed";
}
?>

What I want to do is post my image via ajax but return the value back to my js file

I'm not certain on the CORS issue

Here's my first attempt   http://peter-gosling.com/testupload/   HTML

<!DOCTYPE html>

            var fileName = $(this).val();
            console.log(fileName);
            get_image_url(fileName)
});

//UPLOAD IMAGE RETURN URL
    function get_image_url(imageurl) {
        var dataString = "url="+imageurl;
        //datastring = $("input[name=sessiontitle]").val();
        //AJAX code to submit form.
        $.ajax({
        type: "POST",
        url: "http://www.peter-gosling.co.uk/testupload/saveimage2.php",
        data: dataString,
        cache: false,
        success: function(html) {
        alert(html);
        }
        });
    }
    </script>
</body>

I had posted a similar post  a few days back, about an display script which is supposed to retrieve a stored image from my database and displays it on an html page, but fails to do so.  Someone suggested that I  upload my image onto a folder on the server and then save the image path name in my database.  I found this script(below)  which does just that.  It uploads the image into a folder on the server called images and stores the image path into a table in my database called images and I know this script works because i saw the file saved in the images folder and the path name inserted into the images table.

Well, needless mentioning, the picture isn't displayed.  Just a tiny jpeg icon is displayed at the top left hand corner of the page.  Figuring out that the problem might be the lack of a header that declares the image type, I add this line
header("Content-type: image/jpeg");
but all it does is display a blank white page, without the tiny icon this time.  What am I missing? Any clues??

So its a virtual pet script I'm making.
This script changes the image of the pet with time.
It also puts the user's name,in text on the image.
For some reason It doesnt turn out too well=
http://amiteka.comli.com/viewpet_forum.php?id=1
  Can someone tell me what is wrong with the script or how I can make it show something like; Error on line #


<?php

require_once('./inc/config.php');

function greaterDate($dformat, $beginDate, $endDate)

Thank you for any help.

I've been creating my own image upload script which takes in several parameters to style an image, however when the function is used new width and new height are specified but I need to use these values to determine cropping coordinates.

What I want is when a new width and height is specified, if it is squared i.e. new width is equal to new height AND the original image is not squared i.e. it is a vertical or horizontal rectangle then the central part of that image will be taken.

So for example if the user uploads an image 500px high and 100px wide and sets the new width and height both at 100px the new image should be a 100px by 100px square which is taken 200px from the top of the original image.

Here is the functions I currently use so far. It's just the coordinates function I can't seem to figure out. Can anyone please help me out:-

Code: [Select]

//gets the extension of an uploaded file
function getExtension($file) {
$i = strrpos($file,".");//Gets the position of the "." in the filename
if (!$i) { return ""; }//If there is no "." the function ends and returns ""     
$l = strlen($file) - $i;
$ext = substr($file,$i+1,$l);
$ext = strtolower($ext);
return $ext;
}

//checks image dimensions and scales both sizes by ratio if it exceeds the max
//$w = width, $mw = max width, $h = height, $mh = max height,
function checkSize($w, $mw, $h, $mh){

if($w > $mw){//Checks if width is greater than max width
$ratio = $mw / $w;
$h = $h * $ratio;
$h = round($h);
$w = $mw;
}

if($h > $mh){//Checks if height is greater than max height
$ratio = $mh / $h;
$w = $w * $ratio;
$w = round($w);
$h = $mh;
}

return array($w, $h);

}

//Used to get the coordinates to resize an image by
function getCoords(){


}

//$f = the file, $ext = file extension, $nw = new width, $nh = new height, $mw = max width, $mh = max height, $nf = new filename, $fo = folder, $des = file size description, $q = quality
function imageUpload($f, $ext, $nw, $nh, $mw, $mh, $nf, $fo, $des, $q){

//create image from uploaded file type
if($ext=="jpg" || $ext=="jpeg" ){
$src = imagecreatefromjpeg($f);
}else if($ext=="png"){
$src = imagecreatefrompng($f);
}else{
$src = imagecreatefromgif($f);
}

//creates a list of the width and height of the image
list($w,$h)=getimagesize($f);

//sets the coordinates for resizing to 0 by default
$dx = $dy = $sx = $sy = 0;

//if new width and height are both 0 then a resize is not required so original dimensions need to be validated in case they exceed their max
if($nw == 0 && $nh == 0){

if($w > $mw  || $h > $mh){//checks if width or height are greater than their max

list($w, $h) = checkSize($w, $mw, $h, $mh);

}

$nw = $w;
$nh = $h;

}else if($nw == $nh && $w !== $h){//this is for if the resized image needs to be squared but the original image is not a square

//COORDS FUNCTION NEEDED HERE

}

$desext = "";//sets the description extension to "" by default
if($des !== 0){//Checks if $des is set or not
$desext .= "_".$des;//appends des to $desext ready to be appended to the filename
}

$foext = "";//sets the folder extension to "" by default
if($fo !== 0){//Checks if $fo is set or not
$foext .= $fo."/";//appends folder to $foext ready to be appended to the filename
}

$qv = 100;//sets the quality value to 100 percent by default
if($q !== 0){//Checks if $q is set or not
$qv .= $q;//sets the quality value to the passed value
}

$tmp=imagecreatetruecolor($nw,$nh);
imagecopyresampled($tmp,$src,$dx,$dy,$sx,$sy,$nw,$nh,$w,$h);
$fn = "images/".$foext.$nf.$desext.".jpg";//sets the final filename for upload
imagejpeg($tmp,$fn,$qv);//uploads the file

//empty variables and clear image
imagedestroy($src);
imagedestroy($tmp);

}

Hi guys,

I've got an image uploader based on Uploadify, first let me set out what I want the script to do and what it currently does/doesn't do:

Upload files of various types into folders named with the Order ID - OK Process the files by checking the file type and acting accordingly - OK Create thumbnails of the images in the /thumbs subdirectory - OK If the file is a PDF, create JPEG images of all pages and subsequent thumbnails - OK If the file is a ZIP, unzip and re-process the contents based on the above rules - FAIL
As you can see I'm nearly at the end of my wishlist with this script, currently when it receives a ZIP file is unzip's it correctly placing the contents in the parent (Order-ID) directory however I'm then left with the same situation I have at the very beginning of the script, for example:

File in -> "What kind of file are you?" -> Process file based on the answer.

What I need to do is:

File in -> "What kind of file are you? Oh! a Zip File, let's unzip and ask the same question of the contents!" -> Process contents.

So basically I need to ask the same question twice, once of the zip and once of the contents of the unzipped file. This is where I'm struggling, someone told me to use a function which I tried but it kept breaking and I wasn't sure why. Therefore I have attached 2 files. 1 which currently works 99% except for "asking the question again" and one which doesn't work but I was told is the right way to do it 

File 1: Works 99%.

If anyone could help me with this I'd greatly appreciate it, I've been reading so many guides on functions and arguments my brain is fried and I fear I've strayed from the subject of what I want to do!

Many thanks.

Hello,

My upload script is working for the most part and while I know that I need a couple of little fixes and will need help with those I also wouldn't mind some tips on how I could have written it better in the first place.

The 2 problems I am having.
1. If the copy image fails the script doesn't and still creates a database entry. I would like to stop it from doing that but can't seem to work it out.
2. My mate is getting file type errors even though he is trying to upload small .jpg files. I can't seem to recreate the problem. Maybe someone can see something that might be problematic??
