I am working on a Wordpress website and I have a very simple <input type="image"> through which user can send image files.
I have some very specific requests and I would like the uploaded file to be:
Is there a way I can set this limits via JS/jQuery?
To get info about image before upload use wp_handle_upload_prefilter . Aspect ratio is comparing width and height.
function test($file) {
$data = getimagesize($file['tmp_name']);
error_log(print_r($data,true));
//Returns
// Array (
// [0] => 3000 // width
// [1] => 3000 // height
// [2] => 3
// [3] => width="3000" height="30000"
// [bits] => 8
// [mime] => image/png
// )
error_log(print_r($file,true));
//returns
// Array (
// [name] => filename.png
// [type] => image/png
// [tmp_name] => /tmp/phpEJC5NR
// [error] => 0
// [size] => 4347 // file size in bits
// )
return $file;
}
add_action('wp_handle_upload_prefilter','test');
