Adds jquery.validation functionality to silverstripe 3.0+ forms.

JQueryValidation

Adds jquery.validation functionality to silverstripe 3.0+ forms. Visit http://jqueryvalidation.org/ for more information., _(*1)

Usage

To make it work, make sure your page has jquery included. For sake of backward compartibilty for old browsers you also might load json2.js. Both files can be found in modulefolder/javascript/libs., _(*2)

Start up validation on a form like this:, _(*3)

$form = new Form(
    $this,
    'Form',
    $fields,
    new FieldList(
        new FormAction(
            'FormHandler',
            'Submit'
        )
    ),
    RequiredFields::create(....)
);

JQueryValidation::create($form, $config)

Expects a form and an optional config array, which overrides values from the base config. Take a look into JQueryValidation::$base_config for available key / value pairs., _(*4)

JQueryValidation::create(
    $form,
    array(
        'validator' => array(
            'errorElement' => 'div'
        )
        ...
        ..
        .
    )
);

JQueryValidation->generate()

For automated creation use:, _(*5)

// This will inspect all form fields and add their validation methods.
// It also will add required checks provided by the form's RequiredFields.
JQueryValidation::create($form)->generate();

// It is also possible to provide custom error messages and behaviour through passing a config array like this:
JQueryValidation::create($form)->generate(array(
    'messages' => array(
        'CheckboxField_DATA' => array(
            'required' => 'Custom message'
        )
    )
));
// Expected hooks are messages, rules, groups.

JQueryValidation->custom()

If you want to provide your own validation file you can use this:, _(*6)

JQueryValidation::create($form)->custom('path/to/your.js');

// It is also possible to provide information about which additional js files should be loaded, like this:
JQueryValidation::create($form)->custom(
    'path/to/your.js',
    array(
        'additionalMethods',    // load additional-methods.min.js
        'metadata',             // load jquery.metadata.js
        'moment',               // load moment.min.js
        'date'                  // load date.js
    )
);

Some of this methods are automatically invoked if JQueryValidation->generate() is used. Extra functionality can be added by adding them into $custom parameter. The following example creates a field which validates for an url:, _(*10)

// adding a simple textfield to the field list
$fields->push(
    TextField::create(
        'URL',
        'Your website'
    )
);
...
..
.
// later, when starting the validation you can add url validtition to this field like this:
JQueryValidation::create($form)
    ->generate(
        array(
            'messages' => array(
                'URL' => array(
                    'url' => 'Please enter a valid url.' // add error message
                )
            ),
            'rules' => array(
                'URL' => array(
                    'url' => true // add url validation
                )
            )
        )
);
