Improves the built-in form block so it submits via ajax. Also uses a table-less layout for easier styling.
This repository is a fork of https://github.com/jordanlev/c5_ajax_form

• Download repository as .zip
• Add the form directory in your package /packages/nameofyourpackage/blocks.
• If you want to use this block within your package add the following code in the on_start method of your package controller:

    $environment = \Environment::get();
    $environment->overrideCoreByPackage('blocks/form/controller.php', $this);

    Route::register('/tools/blocks/form/responder', function() {
      include('packages/nameofyourpackage/blocks/form/tools/responder.php');
    });

• Replace the package name in the controller namespace of: /packages/nameofyourpackage/blocks/form/controller.php and replace nameofyourpackage with the name of your package in /packages/nameofyourpackage/blocks/form/tools/responder.php.

• Optionally move view.php from blocks/form/view.php to blocks/form/templates/nameofyourtemplate/view.php to prevent from overriding the default template.

Although I haven't tried nor documented, this block should be easy to implement without a package, directly in your /application directory.
