PHP Read_Exif_Data and Adjust Orientation

PHP read_exif_data and Adjust Orientation

The documentation for imagerotate refers to a different type for the first parameter than you use:

An image resource, returned by one of the image creation functions,
such as imagecreatetruecolor().

Here is a small example for using this function:

function resample($jpgFile, $thumbFile, $width, $orientation) {
    // Get new dimensions
    list($width_orig, $height_orig) = getimagesize($jpgFile);
    $height = (int) (($width / $width_orig) * $height_orig);
    // Resample
    $image_p = imagecreatetruecolor($width, $height);
    $image   = imagecreatefromjpeg($jpgFile);
    imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
    // Fix Orientation
    switch($orientation) {
        case 3:
            $image_p = imagerotate($image_p, 180, 0);
            break;
        case 6:
            $image_p = imagerotate($image_p, 90, 0);
            break;
        case 8:
            $image_p = imagerotate($image_p, -90, 0);
            break;
    }
    // Output
    imagejpeg($image_p, $thumbFile, 90);
}

PHP Upload with EXIF Orientation based rotation

Try this. We're taking the file, and if it's a jpeg then we rotate it. If not, we don't. We take the $image variable that is created and generate a jpeg in the location you wanted.

include 'includes/democonnect.php';
$cnum=$_POST['cnum'];
$amount1=$_POST['amount1'];

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["uploadReceipt"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["uploadReceipt"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;

        $info = $check;
        if ($info['mime'] == 'image/jpeg') $image = imagecreatefromjpeg($_FILES["uploadReceipt"]["tmp_name"]);
        elseif ($info['mime'] == 'image/gif') $image = imagecreatefromgif($_FILES["uploadReceipt"]["tmp_name"]);
        elseif ($info['mime'] == 'image/png') $image = imagecreatefrompng($_FILES["uploadReceipt"]["tmp_name"]);
        else exit;//Do whatever you want here.

        if($info['mime'] == 'image/jpeg') {
            $exif = exif_read_data($_FILES["uploadReceipt"]["tmp_name"]);
            if(isset($exif['Orientation'])) {
                $orientation = $exif['Orientation'];
            }
        }

        if(isset($orientation)) {
            switch($orientation) {
                case 3:
                    $image = imagerotate($image, 180, 0);
                    break;
                case 6:
                    $image = imagerotate($image, -90, 0);
                    break;
                case 8:
                    $image = imagerotate($image, 90, 0);
                    break;
            }
        }

        //////////
        // $image is your new, rotated file.
        //////////
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}

$filename = 'receipt'.time() . basename($_FILES["uploadReceipt"]["name"]);

 // Check file size
if ($_FILES["uploadReceipt"]["size"] > 5000000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif"  && $imageFileType != "bmp" ) {
    echo "Sorry, only JPG, JPEG, PNG, GIF, and BMP files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0 || !isset($image)) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (imagejpeg($image, $target_dir.$filename)) {
        echo "The file ". $filename. " has been uploaded.";

        $query = "INSERT INTO tblReceiptUpload
        (cnum,pointer1,amount1)
        VALUES(?,?,?)";
        $params1 = array($cnum,$filename,$amount1);
        $result = sqlsrv_query($conn,$query,$params1);

        sqlsrv_close($conn);

    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
