sfJqueryFormValidation plugin
==============

The `sfJqueryFormValidationPlugin` is a Symfony plugin that automatically adds client-side
form validation to Symfony Forms (including embedded forms).

The client side validation is performed using the jQuery library and the jQuery Validation plugin.

It automatically reads validation rules and messages in from the form validation schema and applies them
on the client side.

The validation is added using progressive-enhancement techniques, so no javascript code is actually
written to your HTML page.

The error messages are written to the page using the same HTML elements as the server-side validation
so you only need one set of styling rules to cover the server and client side validation messages.

Installation
------------

  * Add the jQuery libary and the jQuery Validation plugin on your site in `view.yml`. You can either download them from
  http://docs.jquery.com/Downloading_jQuery and http://bassistance.de/jquery-plugins/jquery-plugin-validation/ respectively. Alternatively
  you can just include them from their respective CDN's:

        [yml]
        default:
          javascripts:
            - /sfJqueryFormVal/js/jquery-1.4.min.js
            - /sfJqueryFormVal/js/jquery.validate-1.7.min.js
            - /sfJqueryFormVal/js/validate.extended.js
            - /sfJqueryFormVal/js/validate.additional-methods.js

  * Install the plugin

        $ symfony plugin:install sfJqueryFormValidationPlugin

  * Add the following filter to `filters.yml` below the "# insert your own filters here" comment:

        [yml]
        # insert your own filters here
        sfJqueryFormValidation:
          class: sfJqueryFormValidationFilter

  * Enable module in your `settings.yml`:

        [yml]
        all:
          .settings:
            enabled_modules:      [default, sfJqueryFormValidation]

  * Clear your cache

        $ symfony cc


Optional configuration settings
-----------------------

  * There are a couple of extra configuration options that can optionally be added
  to `app.yml` to change the behavior of plugin:

        [yml]
        all:
          sf_jquery_form_validation:
            ajax_post: false
            default: disabled
            forms: [RegistrationForm, Login]
            date_method: dateEN

  * The default behavior of the plugin is to add client-side validation to all Symfony forms. If you
  wish to manually select which forms get the client-side validation, you can set default:disabled, which
  prevents the plugin from validating forms by default and then specify the desired forms to receive validation
  in the forms: option.

  * The date-validation method (date) in the jQuery form validation plugin checks for US style dates, you can
  optionally specify an alternate method for checking dates. In the example above, the date method is changed
  to dateEN (which then needs to be defined). The example definition for dateEN is shown below.

Custom date validation method - dateEN
-----------------------

  * The jQuery form validation plugin allows you to define custom validation methods. This is a custom method
  for validating dates as dd-mm-yyyy. It can be added to the same js file as the the form validation
  plugin or just added somewhere in a js file that is included on pages that contain forms.

        [js]
        jQuery.validator.addMethod(
          "dateEN",
          function(value, element) {
            var check = false;
            var re = /^\d{2}\-\d{2}\-\d{4}$/
            if( re.test(value)){
              var adata = value.split('-');
              var gg = parseInt(adata[0],10);
              var mm = parseInt(adata[1],10);
              var aaaa = parseInt(adata[2],10);
              var xdata = new Date(aaaa,mm-1,gg);
              if ( ( xdata.getFullYear() == aaaa ) && ( xdata.getMonth () == mm - 1 ) && ( xdata.getDate() == gg ) )
                check = true;
              else
                check = false;
            } else
              check = false;
            return this.optional(element) || check;
          },
          "Please enter a correct date"
        );
