Laravel - How validate max size of an image that exceed upload_max_filesize directive

I'm using ajax request to send an image to server and returning immediately some data. (for test)

return [
  'photo' => Request::file('avatar'),
  'hasFile' => Request::hasFile('avatar'),
  'extension' => Request::file('avatar')->getClientOriginalExtension(),
  'size' => Request::file('avatar')->getClientSize(),
  'maxFileSize' => Request::file('avatar')->getMaxFilesize()
];

When image is less than upload_max_filesize directive, i have this response:

{"photo":{},"hasFile":true,"extension":"jpg","size":900498,"maxFileSize":2097152}

When image is greater than upload_max_filesize directive, i have this response:

{"photo":{},"hasFile":false,"extension":"jpg","size":0,"maxFileSize":2097152}

Look at size on last response. How i can validate it?

You need to use size instead of max to validate file size. max:value

Blockquote The field under validation must be less than or equal to a maximum value. Strings, numerics, and files are evaluated in the same fashion as the size rule So we go to the Size rule:

size:value

Blockquote The field under validation must have a size matching the given value. For string data, value corresponds to the number of characters. For numeric data, value corresponds to a given integer value. For files, size corresponds to the file size in kilobytes.

get the file size 

$filesize = Input::file('photo')->getSize();

push the file size in the data to be validated 

$data['filesize'] = $filesize;

your rule should look like this $rules = ['filesize' => 'size:max size in KB'];

you can also do this when the file size == false, before call the form validation

 $file_size    Input::file('avatar')->getSize() // false
 if ($filesize){
  //  continue 
 }

I think this approach is a lot easier.

Hope this help.

As I know you could be able to validate a type of image by client side script but in case of size its completely server side validation .
