如何修复图像方向并使用PHP上传图像 [英] how to fix Orientation of the image and upload image using PHP
问题描述
我正在尝试上传图像并修复图像的旋转,然后将其更新到服务器,我必须在此链接中使用答案:
I'm trying to upload an image and fix the rotate of the image, then update it to a server, I have to use the answer in this link: here but it does not work still the image with the wrong orientation
php中的代码:
//START Update the user image
if(isset($_POST['user_image_id'])){
$upload_image_id = $_POST['user_image_id'];
$user_image = $_FILES['user_image']['name'];
$filePath = $_FILES['user_image']['tmp_name'];
$image = imagecreatefromstring(file_get_contents($_FILES['user_image']['tmp_name']));
$exif = exif_read_data($filePath);
if(!empty($exif['Orientation'])) {
switch($exif['Orientation']) {
case 8:
$image = imagerotate($image,90,0);
break;
case 3:
$image = imagerotate($image,180,0);
break;
case 6:
$image = imagerotate($image,-90,0);
break;
}
}
// $image now contains a resource with the image oriented correctly
//create image target to upload
$image_target = $folder_target.basename($_FILES['user_image']['name']);
//upload the image the and update the name of the image
if(move_uploaded_file($_FILES['user_image']['tmp_name'], $image_target)){
if ($conn->query("UPDATE `users` SET `image`='$user_image' WHERE `id` LIKE '$upload_image_id'")){
echo 1;
}else{
echo "not update the name, Proplem";
}
}else{
echo 'image not uploaded';
}
}
我使用了图片库" https://github.com/Al-Alloush /JavaScript-Load-Image ",以修复浏览器中图像的方向,但是当我提交图像并将其上传到服务器时,其方向仍然相同
I used the image library "https://github.com/Al-Alloush/JavaScript-Load-Image", to fix the orientation of the image in browser but when I submit and uploaded the image to server still the same oriented
请帮助,:)
推荐答案
旋转图像后尚未保存图像.上载之前,请按以下步骤保存.
You haven't saved your image after rotating it. Save is as below before uploading it.
imagejpeg($image, $filePath);
//upload the image the and update the name of the image
if(move_uploaded_file($filePath, $image_target)){
....
}
注意:
imagejpeg
应该用于扩展名JPG
的图像.对于PNG
,请使用imagepng
.
Note:
imagejpeg
should be used for images withJPG
extension. ForPNG
, useimagepng
.
