I need to check if a file has a valid MIME type, if the file size is ok and if its dimensions are ok, then upload file.
So when everything is OK, I can use:
complete: function(file){
// do something here.
}
but what if the size of file was invalid? In my PHP script I return an error message:
return json_encode(['error' => 'size is invalid']);
OR
return Response::json(['error' => 'size is invalid'], 500 ];
// this is Laravel 4 syntax. returns a json array and 500 as status code.
but how can I handle that error
in DropzoneJS?
I tried adding a second parameter to the complete()
function but it's not working.
complete: function(file, response){
console.log( response ); // this does not work.
}
To get the response after the file was submitted to server use this in DropzoneJS:
success: function(file, response) {
alert(response);
}
And to validate the file before uploading it use this:
complete: function(file) {
if (file.size > 3.5*1024*1024) {
alert("File was Larger than 3.5Mb!");
return false;
}
if(!file.type.match('image.*')) {
alert("Upload Image Only!");
return false;
}
}
If your server is returning response
in JSON
, you'll need to use JSON.parse
before alert
ing it.
Hope it'll help you! Cheers! :)
Set the HTTP response code http_response_code(415); // Unsupported Media Type or http_response_code(415); // Not Acceptable
function showError($message)
{
http_response_code(415);
die($message);
}
