Laravel get mimeType from uploaded image - php

Question

I am using jQuery file uploader to upload a resized image, convert it to blob and save it as blob into a DB.
For the database I also need to save the mimeType, which I see in the request, which I receive, but I dont understand how to get the mimeType value.
The code to send the image:
var formData = new FormData();
formData.append("_token", $('meta[name="csrf-token"]').attr('content'));
formData.append("user_id_val", $('.user-general-i').data('userid'));
// HTML file input, chosen by user
formData.append("userfile", data.files[0]);
var request = new XMLHttpRequest();
request.open("POST", "http://localhost.eu/home/create_comment_images");
request.onload = function(oEvent) {
if (request.status == 200) {
console.log('success');
} else {
console.log(request.status);
}
};
request.send(formData);
Code on the server:
public function create_comment_images(Request $data) {
\Log::info($data);
try {
$path = $data->userfile;
$logo = file_get_contents($path);
$base64 = base64_encode($logo);
return ['success' => true];
} catch (\Exception $e) {
return ['success' => false, 'message' => $e->getMessage()];
}
return ['success' => false, 'message' => 'Something went wrong'];
}
The log info shows me this:
array (
'_token' => 'QxOqetFU2Re6fwe442vksGNnvV0C88v8dcrFpAp',
'user_id_val' => '568092',
'userfile' =>
Illuminate\Http\UploadedFile::__set_state(array(
'test' => false,
'originalName' => 'Unbenannt.png',
'mimeType' => 'image/png',
'error' => 0,
'hashName' => NULL,
)),
)
I am almost there, I need the get the mimeType information from the array.
I tried:
$data->userfile->mime_content_type
$data->userfile->mimeType
$data->userfile['mimeType']
$data->userfile[0]['mimeType']
Nothing works. Any ideas how to extract that information?

Answer 1

On Laravel you can use the intervention library. This library is very powerfull you can change the format, resize and do all kind of stuff.
Here a basic example..
// read image from temporary file
$img = Image::make($_FILES['image']['tmp_name']);
// get or sets the mime type.
$mimeType = $img::mime();
// save image
$img->save('foo/bar.jpg');
// Get image as string.
$string = base64_encode($img->encode('jpg'));

To get the mimetype from the uploaded file header, you can call getMimeType() on the \Illuminate\Http\UploadedFile class.
$uploadedFile = $data->file('userfile');// or
$mimeType = $uploadedFile->getMimeType()
