Img validation error: "The given data was invalid." when uploading images greater than 2mb

the post_max_size??? try...

upload_max_filesize = 20M

post_max_size = 21M

@siangboon , thank you for you suggestion. Hmmm, after changing the php.ini and restarting, I do see post_max_size = 21M and upload_max_filesize = 20M, but still images > 2MB are not uploading, I am getting the same error message.

"The given data was invalid." error does not seem to be the error for upload file size limit... probably check the log and screenshot the log,error and code also may help other to understand more...

btw, did you include ""enctype="multipart/form-data"" in the form??

@siangboon, when I upload images greater than 2MB, I still get the "The given data was invalid" validation error msg, and from what I see the validation msg is correct, because the uploaded file is not mimeType: "image/jpeg". There are no PHP errors in the log file. If I dd($request['files']); in the controller, for images greater than 2MB I see this:

Illuminate\Http\UploadedFile {#635
  -test: false
  -originalName: "IMG_1857.JPG"
  -mimeType: "application/octet-stream"
  -error: 1

}

for images that are less than 2MB,

Also, below is what I currently have in my php.ini for Data Handling and File Uploads (a lot of the comments are removed):

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 20M

; Maximum number of files that can be uploaded via a single request
max_file_uploads = 20

how about temporarily increase the below setting just for testing?

max_execution_time=900
memory_limit=60M
max_input_time=900

Hmm..., this is a "tricky one". I did made the changes, but still, < 2mb is OK, > 2mb. throws an error. I am also noticing, when the image is close to 2mb, it takes, sometimes up to few seconds, to upload, but when I select an image > 2mb, the 422 comes back instantly, it doesn't even try. In few days I'll be pushing stuff up to staging server, curious to see how it will behave there, possible that only my local development is not properly configured.

What is also interesting, that I can upload 6 images at once, as long as each image is less than 2mb, it works/uploads the files.

Ok, little embarrassing, but finally figured it out. My issue was that I have multiple PHP versions installed, and normally I change the php.ini by boing through Wamp menu (menu does show the correct PHP version), but some how it points to different version PHP.ini. Anyhow, I found the code below, which I found on: https://stackoverflow.com/questions/26209377/how-can-i-upload-a-file-in-php-large-than-about-2mb Ran the code in editor and yes, the upload_max_filesize was set @ 2mb. Below is the code, if anyone else comes a cross similar issue, try running the code first.

echo ini_get("memory_limit")."\n";
ini_set("memory_limit","30M");
echo ini_get("memory_limit")."\n";

echo ini_get("post_max_size")."\n";
ini_set("post_max_size","20M");
echo ini_get("post_max_size")."\n";

echo ini_get("upload_max_filesize")."\n";
ini_set("upload_max_filesize","19M");
echo ini_get("upload_max_filesize")."\n";

Thank you @siangboon for all your help!
