PHP - Ajax Upload Image Via Php Script

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??

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


I have an image uploading script that won't upload images...


It worked at one point when i had folder permission at 0777 but i was told that is risky so i changed it to 0775


Now it won't work and i can't use 0777.




Any one know what i need to do to get it to work?

This is my script:
Code: [Select]
<?php
$salt = 35322232414;
$name = $salt.$safe;


$name = md5($name);


if(isset($_POST['submit'])){ 
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 1000000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo $_FILES["file"]["error"];
    }
  else
    {
   $filename = md5(serverdate()) . $_FILES["file"]["name"];
    if (file_exists("userimages/".$name."/".$filename))
      {
      echo "Image already uploaded!";
      }
    else
      {
   if (is_dir("userimages/".$name) == FALSE){
      mkdir("userimages/".$name, 0775); //permissions 
   }


   
      move_uploaded_file($_FILES["file"]["tmp_name"], "userimages/".$name."/" . $filename);
     echo "Image has been uploaded!";
      
}

Error i get:

Hi all

I have a script that takes up to 3 images and resizes them. It works except for if you try and upload images over roughly 500kb. I then get the message:

Fatal error: Allowed memory size of X bytes exhausted (tried to allocate Y bytes)

Here's a snippet of the code for one image:

Code: [Select]
// Process image 1 :

if(!empty($_FILES['image1']['name'])) {
$imagelarge = $_FILES['image1']['tmp_name'];
$imagelargemain = $_FILES['image1']['name'];
$pathInfo = pathinfo($imagelargemain);
$rand = rand(1, 100000000000000);
$name = $rand . '.' . $pathInfo['extension'];
$src = imagecreatefromjpeg($imagelarge);
list($width,$height)=getimagesize($imagelarge);
if ($width > $height) {
$newwidth=600;
$newheight=($height/$width)*$newwidth;
}
elseif ($height > $width) {
$newheight=400;
$newwidth=($width/$height)*$newheight;
}
$center_x = (600/2)-($newwidth/2);
$center_y = (400/2)-($newheight/2);
$tmp=imagecreatetruecolor(600,400);
$white = imagecolorallocate($tmp, 255, 255, 255);
imagefill($tmp, 0, 0, $white);
imagecopyresampled($tmp,$src,$center_x,$center_y,0,0,$newwidth,$newheight,$width,$height);
$filename = WEB_UPLOAD."images/adverts/". $name;
imagejpeg($tmp,$filename,100);
imagedestroy($src);
imagedestroy($tmp);
$image_sql = mysql_query("UPDATE `adverts` SET image1 ='".$name."' WHERE id='".$insertid."'") or die ("Error updating database");
}

Any ideas why this happens?

Many thanks

Pete

Hi all, been a while since I've been on here.   I am in the process of designing a site similar to dating sites like plenty of fish, or ok cupid. The only spot I am running into trouble is with images.    If you are familiar with either of these sites, you will understand what I am looking for.    Basically, a user is able to upload one or more images via an uploader (Not sure if it's ajax or flash to be honest, but I would like to stick to PHP/Ajax).   While uploading, they have the ability to crop their images to specific sizes set by the site - for example, the image must be cropped to fit  a 400 px X 400 px area, so they have the ability to decide which part of a larger image is saved rather than just have the system crop it and perhaps not show what was intended.    After they finish and click upload, the image is saved to the server, as well as a thumbnail, which, without a refresh, is then added to their page along with their previous images if there were any. From that point, they have the option to delete images they don't like, set the main image for their profile and edit/add captions to the images, again, all without refreshing the page.    Would anyone happen to know of a script I could start with and change to suit my needs, but that would pretty much allow this kind of image uploading/manipulation? I've done google searches for hours now and have looked at a ton of scripts but not a single one I have found seems to be able to do any of these things. Most just have multiple file uploads with cropping ability, but not by the users themselves, just a predetermined dimension.    Any help pointing me in the right direction would be greatly appreciated.    Jax

Hi all,

As you will see this is my first post in I really hope somebody can nail this for me, as I have been working on this for some time and I cannot get it to work.

Basically this is the final part of a CMS I'm building, and all was fine until I needed to build in an option of a multiple image uploader to accompany all other stock details.

I have managed to nail the 'insert' part of the multiple image uploader in this case up to 4 images, and the code is below for this part, any help with improvements though will be greatly appreciated.

All seems to be fine above, I can upload 1,2,3 or 4 images and the image goes into the server and the path to the database.

But I then needed the option for my client to be able to click to edit a certain stock and then aswel as edit the other details, if he wanted to change one pic, no pics or all 4 he could and when he clicked submit, if there was a new image it would change if not it would stay as it is.

So here is my attempt and at the moment it doesnt work, so I'm looking for help of any kid and anything can change.

What happens above as its all on the same page, is when a stock item is selected to be edited the form to update the images changes to the image upload options above, instead of the original ones for a new stock item at the top of this post.

I can provide anything you need to help me with this, so please can somebody take a look and see if it can be got working, as its been a long problem for me this.

Cheers

so what i have going on is that i need help writing a basic script to upload original and copy with resize for thumbnail. then also need to rename both image files with content in the form.
My server supports GD Library and that imagemagik or whatever it is lol.

upload dirs
orig: ../media/photos/
thumb: ../media/photos/thumb/

mySQL DB:
name: m_photos
fields: id(INT)
           m_cat(varchar)
           m_sub_cat(varchar)
           pic(varchar)
           description(varchar)
           p_group(varchar)

I have the form written up for how it should look like:
Code: [Select]
<form action="upload.php" method="post" enctype="multipart/form-data">
  Upload an image for processing<br />
  <input type="file" name="Image"><br />
  <select name="sub_group">
    <option value="Photo Shoot">Photo Shoot</option>
    <option value="Live Performances">Live Performances</option>
    <option value="Randoms">Randoms</option>
    <option value="Fan Photos">Fan Photos</option>
  </select><br />
  Location:
  <input type="text" name="p_group" /><br />
  Date of Pic:
  <input type="text" name="date" /><br />
  Description:
  <input type="text" name="description" /><br />
  <input type="submit" value="Upload">
</form>

so what needs to happen is for the file upload name. it needs to grab a count from "p_group" database to give it a starting number in a "00" pattern and then the date of pic needs to go in there next then the p_group name. so when the files gets uploaded it would look something like this after upload. "03 - Oct 21, 2011 - The Mex.jpg"
NOTE: all pics must be converted to ".jpg" extension.

both the orig and thumb will use that same file name cuz they just go into different dirs

re-sizing for the thumbnail should be done by aspect ratio and needs to either be 300px width or 400px height.

so if anyone would like to help me out please do. im not the greatest at writing in php yet

The Script:

<?php
if (isset($_POST['submit'])) {
    $j = 0; //Variable for indexing uploaded image 
    
	$target_path = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/uploads/"; //Declaring Path for uploaded images

    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array       
      
	  if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
                && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';



                for ($i = 0; $i < count($_FILES['file']['name']); $i++) {
                    $tqs = "INSERT INTO images (`original_image_name`, `image_file`, `date_created`) VALUES ('" . $_FILES['file']['name'][$i] . "', '" . $new_image_name  . "', now())";
                    $tqr = mysqli_query($dbc, $tqs);
                }



                // To create the thumbnails.
                function make_thumb($src, $dest, $desired_width) {

                    /* read the source image */
                    $source_image = imagecreatefromjpeg($src);
                    $width = imagesx($source_image);
                    $height = imagesy($source_image);

                    /* find the "desired height" of this thumbnail, relative to the desired width  */
                    $desired_height = floor($height * ($desired_width / $width));

                    /* create a new, "virtual" image */
                    $virtual_image = imagecreatetruecolor($desired_width, $desired_height);

                    /* copy source image at a resized size */
                    imagecopyresampled($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);

                    /* create the physical thumbnail image to its destination */
                    imagejpeg($virtual_image, $dest);
                }


                $src = $target_path;

                $dest = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/thumbs/";

                $desired_width = 100;

                make_thumb($src, $dest, $desired_width);




            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }

}


?>

With this:

$dest = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/thumbs/";

I get this error message:

Warning: imagejpeg(C:/xampp/htdocs/gallerysite/multiple_image_upload/thumbs/): failed to open stream: No such file or directory in C:\xampp\htdocs\gallerysite\multiple_image_upload\upload.php on line 49

With this:

$dest = "http://localhost/gallerysite/multiple_image_upload/thumbs/";

I get this error message:

Warning: imagejpeg(http://localhost/gallerysite/multiple_image_upload/thumbs/): failed to open stream: HTTP wrapper does not support writeable connections in C:\xampp\htdocs\gallerysite\multiple_image_upload\upload.php on line 49

When I try deleting the "thumbs" folder and then try to upload an image, then I get this error message:

Warning: imagejpeg(C:/xampp/htdocs/gallerysite/multiple_image_upload/thumbs/): failed to open stream: Invalid argument in C:\xampp\htdocs\gallerysite\multiple_image_upload\upload.php on line 49

The spot of line 49 is this, at the spot where the script creates the thumbnails:

/* create the physical thumbnail image to its destination */
                    imagejpeg($virtual_image, $dest);
                }

Also, with this part right here I am not getting an error message, which means that this part works fine in comparison:

$target_path = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/uploads/"; //Declaring Path for uploaded images

The script itself works fine. The script also uses javascript for multiple image upload.   I am using XAMPP. The folder "thumbs" is set to "read-only", when I try to uncheck the "read-only" option in the properties in Windows then it sets itself back again to "read-only". Then again, the script works fine when it comes to the "uploads" folder. This is mentioned in comparison to the "thumbs" folder.   Any suggestions on how to solve this?   EDIT:   I am using XAMPP. The folder "thumbs" is set to "read-only", when I try to uncheck the "read-only" option in the properties in Windows then it sets itself back again to "read-only". I am wondering if I would have issue that the option sets itself back again with Linux?

So this script did work in previous versions oh php but in php5 I get the error, "Sorry, uploaded images must be of type jpg or jpeg, (not )."
So it looks like it's not recognizing my file as a jpeg??

Any contributions towards a fix are GREATLY appreciated!!!   If there are clean, nice (EASY) php5 scripts available for this simple image uploading and thumbnail creation I would consider starting this over.

Hi everyone,

I have a page that i use to upload images to my website, i got a bit fed up of uploading one at a time so i decided to add multiple file fields to the form to upload multiple images at the same time.

Im having a few problems, iv read up he http://www.php.net/manual/en/features.file-upload.multiple.php and it seems all i have to do is add [] to the form names to turn them into arrays. However when i come to upload the images, i keep getting the "$error[] = "Incorrect format!...." error from the code below. I cant seem to figure out what the problem is.

Could anybody please point me in the right direction?

Is this possible? Can you read the contents of a file on a persons computer if they select it with a INPUT TYPE="FILE" html element and then send it via AJAX POST?
