imagecreatefromjpeg() error help

[sasori]

Hi, 

 

before posting this problem, I already tried googling and tried those possible solutions that could help but still failed.

I am having a problem with that PHP function

imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error:

based from what i found in google, some say, use

ini_set("gd.jpeg_ignore_warning", 1);

failed.

 

some say, use

init_set("memory_limit", -1)

still failed

 

I am sure that I am passing .jpg image, how come i keep on getting that error ?

any suggestions of what to do?

How are you "sure that I am passing .jpg image"?  Are you checking it? Are you checking the mime? Are you checking the extension?  Are you sure it isn't a script that has been faked as an image?

Basically, show us the code.

it's not a script..i have a alot of random images in my local storage that i usually use for testing ... here's the part of the code

                $fext = pathinfo($url, PATHINFO_EXTENSION);
                $tmp_name = date('His') . rand() . "." . $fext;
                $filename = $path .'/'. $tmp_name;
                $cont = @file_get_contents($url);
                $op = @fopen($filename, 'w+');
                @fwrite($op, $cont);
                @fclose($op);
                chmod($filename, 0777);
                $orientation = 999;
                $exif = null;
                if (strtolower($fext) == 'jpg' || strtolower($fext) == 'jpeg') {
                    try {
                        $exif = @exif_read_data($filename);
                    } catch (Exception $e) {
                        Yii::log($e->getMessage());
                    };
                    if (!empty($exif) && !empty($exif['Orientation'])) {
                        $orientation = $exif['Orientation'];
                    }
                    $img = imagecreatefromjpeg($filename);

Check the headers of the file.  The extension can be jpeg, but the headers are what gets checked.

it's a jpeg image...how come other jpegs are being read without problems at all?

 

here are the two images, the baby apparel is ok, but the knitted hat is causing that error I mentioned in this thread..

 

i'm not sure if this forum modified those files that i just attached in this reply

Remove the error suppresing and see if anything happens.

[sasori]

the thing that has caused the issue is the white space in the image name...to fix the issue.. the sencha front-end code is now encoding the url being passed to me

When I use high resolution image (5712X4284) and resize using this function for very lower size (136x136). I rotates image to 180 degree. 

Any solution for it ?

[Strider64]

I use the `Intervention` library as it make handling images easier.

Here's how to rotate an image

use Intervention\Image\ImageManager;

$image = (new ImageManager())->make('public/image.jpg')->rotate(45)->save('public/rotated_image.jpg');

and here's an upload script from my website that might help?

<?php
// Include the configuration file and autoload file from the composer.
require_once __DIR__ . '/../config/clearwebconfig.php';
require_once "vendor/autoload.php";
use Intervention\Image\ImageManagerStatic as Image;
// Import the ErrorHandler and Database classes from the clearwebconcepts namespace.
use clearwebconcepts\{
    ErrorHandler,
    Database,
    ImageContentManager,
    LoginRepository as Login
};

$errorHandler = new ErrorHandler();

// Register the exception handler method
set_exception_handler([$errorHandler, 'handleException']);

$database = new Database();
$pdo = $database->createPDO();
$checkStatus = new Login($pdo);

// To check for either 'member' or 'sysop'
if ($checkStatus->check_security_level(['sysop'])) {
    // Grant access
} else {
    // Access denied
    header('location: dashboard.php');
    exit();
}
