The problem is that I have not displayed validation error and the message "further message". Although the validation is successful. The problem is. I don't want to display $messages I tried to walk on it with foreach, but laravel says that it found the $messages. Although the controller $messages displayed. The pattern also shows that the errors I have 0, but in the controller I have shows validation errors.
What's the problem?

try this:i hope it will work for you.
//controller
if ($request->method() == 'POST') {
$rules = [
'name' => 'required',
'email' => 'required'
];
$validator = Validator::make($request->all(), $rules);
if (!$validator->fails()) {
}
else{
//validation_error();
}
}
and use js for validation
$(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));
});
});
