c# - ASP.NET: Validate file size (width and height) before upload -

-

Is there a way to validate image size (height and width) before uploading the image?

I think that using Javascript but I do not know how or maybe some client with ASP.NET validator

Any advice?

This client-side can not be used on JavaScript; You may not use Flash, There will be a file upload component written in the same format that allows files, types, sizes and dimensions to be uploaded by the files they upload.

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way?

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
