Validation error for type=date

[ricardo118]

input type=date works fine on all modern browsers that support that type. The problems arise in non supporting browsers:

Internet Explorer and Safari

The date picker on modern browsers allows the user to pick a date visually and then submits it using the ISO standard of yyyy-mm-dd.

However, on the fallback for IE/Safari there is no visual picker and its just a type=text field, which will fail validation unless the users submit yyyy-mm-dd which is relatively uncommon thing to ask for.

if we look in system/src/Grav/Common/Data/Validation.php Line 490

public static function typeDate($value, array $params, array $field)
{
    if (!isset($params['format'])) {
        $params['format'] = 'Y-m-d';
    }

    return self::typeDatetime($value, $params, $field);
}

we can see there is an optional format. So by modifying our form such as:

date:
  type: date
  label: Date
  validate:
    required: true
    format: 'm-d-Y'

This now passes validation for IE/Safari but will fail in modern browsers where the visual picker still submits yyyy-mm-dd

Potential fix

• add an option for validate: such as date: false that will make sure the field is required but not validated against a date, letting us submit 2 different type of inputs
