模板

@section('content')

<div class="col-md-9">

    <div class="">
        <h2>Contact us!</h2>
    </div>

    <p>
    This is a template for a simple marketing or informational website. It includes a large callout called a jumbotron and three supporting pieces of content. Use it as a starting point to create something more unique.
    </p>
    {{ count($errors)}}
    @if(count($errors) > 0)

问题是我没有显示验证错误和消息“更多消息”。虽然验证成功。问题是。我不想显示我尝试使用foreach在其上行走的$ messages，但是laravel说它找到了$ messages。虽然显示控制器$ messages。该模式还显示错误为0，但是在控制器中显示为验证错误。有什么问题吗？

尝试一下：我希望它对您有用。

//controller

 if ($request->method() == 'POST') {
            $rules = [
                'name' => 'required',
                'email' => 'required'
             ];
            $validator = Validator::make($request->all(), $rules);
            if (!$validator->fails()) {
}
else{
//validation_error();
}
}

并使用js进行验证

$(function () {
    $("#form_id").validate({
        errorElement: 'small', errorClass: 'invalid-feedback',
        rules: {
            name: {
                required: true,
            },
            email: {
                required: true,

            }
        },
        messages: {
            name: {
                required: "Name Field Is Required.",
            },
            email: {
                required: "Email Field Is Required.",
            }
        },
        highlight: function (element) {
            $(element).closest('.form-group').addClass('has-error');
        },
        unhighlight: function (element) {
            $(element).closest('.form-group').removeClass('has-error');
        },
        success: function (element) {
            $(element).closest('.form-group').removeClass('has-error');
            $(element).closest('.form-group').children('small.invalid-feedback').remove();
        },
        errorPlacement: function (error, element) {
            error.appendTo(element.closest('.form-group'));
        },
        submitHandler: function (form) {
            $(window).block({
                'message': '<i class="fa fa-spinner fa-pulse fa-3x fa-fw"></i>',
                'css': {
                    border: '0',
                    padding: '0',
                    backgroundColor: 'none',
                    marginTop: '5%',
                    zIndex: '10600'
                },
                overlayCSS: {backgroundColor: '#555', opacity: 0.3, cursor: 'wait', zIndex: '10600'},
            });

            $.post('', $("#form_id").serialize(), function (data) {
                if (data.code == '1') {
                    swal({
                        title: "",
                        text: data.message,
                        type: "success"
                    }, function () {
                        document.location.href = base_url + '/listing_page';
                    });

                } else if (data === '0') {
                    swal("", "Something wrong while save building information.", "warning");
                } else {
                    swal("", data, "error");
                }
                $(window).unblock();
            });
        }

    });
    $('select').change(function () {
        $("#form_id").validate().element($(this));
    });

});
