CodeIgniter AJAX JSON validator with form validation - php

Question

I am trying to make AJAX form validation work in CodeIgniter.
If you have the same title don't add The data from the form always reports as successful, even if the result is negative.
Is there a mistake in my logic?
Save controller:
public function save(){
$options = array();
$data['title'] = $this->input->post('title');
$data['description'] = $this->input->post('description');
$data['sale_price'] = $this->input->post('sale_price');
$data['purchase_price'] = $this->input->post('purchase_price');
$data['add_timestamp'] = time();
$data['options'] = json_encode($options);
$this->form_validation->set_rules("title", "Title", "required|trim|is_unique[product.title]");
$this->form_validation->set_rules("description", "Description", "required|trim");
$this->form_validation->set_rules("sale_price", "Price", "required|trim");
$this->form_validation->set_message(
array(
"required" => "<b>{field}</b> is not null.",
'is_unique' => 'A %s content has already been added in thistitle.!'
)
);
$validate = $this->form_validation->run();
if($validate){
$insert = $this->db->insert('product', $data);
// alert
if($insert){
$alert = array(
"title" => "Success Sir",
"text" => "Content successfully added",
"type" => "success"
);
}else {
$alert = array(
"title" => "Error Sir",
"text" => "Content failed to load content,
"type" => "danger"
);
}
}
JSON, AJAX, jQuery:
function ajax_set_full(type, title, noty, form_id, id) {
// ajax func
ajax_load(base_url + '' + user_type + '/' + module + '/' + type + '/' + id, 'list', 'form');
}
function form_submit(form_id, noty, e) {
var alerta = $('#form'); // alert div for show alert message
var form = $('#' + form_id);
var can = '';
if (!extra) {
var extra = '';
}
form.find('.summernotes').each(function () {
var now = $(this);
now.closest('div').find('.val').val(now.summernote('code'));
});
//var form = $(this);
var formdata = false;
if (window.FormData) {
formdata = new FormData(form[0]);
}
var a = 0;
var take = '';
form.find(".required").each(function () {
var txt = '*' + req;
a++;
if (a == 1) {
take = 'scroll';
}
var here = $(this);
if (here.val() == '') {
if (!here.is('select')) {
here.css({borderColor: 'red'});
if (here.attr('type') == 'number') {
txt = '*' + mbn;
}
if (here.closest('div').find('.require_alert').length) {
} else {
here.closest('div').append(''
+ ' <span id="' + take + '" class="label label-danger require_alert" >'
+ ' ' + txt
+ ' </span>'
);
}
} else if (here.is('select')) {
here.closest('div').find('.chosen-single').css({borderColor: 'red'});
if (here.closest('div').find('.require_alert').length) {
} else {
here.closest('div').append(''
+ ' <span id="' + take + '" class="label label-danger require_alert" >'
+ ' *Required'
+ ' </span>'
);
}
}
var topp = 100;
if (form_id == 'product_add' || form_id == 'product_edit') {
} else {
$('html, body').animate({
scrollTop: $("#scroll").offset().top - topp
}, 500);
}
can = 'no';
}
if (here.attr('type') == 'email') {
if (!isValidEmailAddress(here.val())) {
here.css({borderColor: 'red'});
if (here.closest('div').find('.require_alert').length) {
} else {
here.closest('div').append(''
+ ' <span id="' + take + '" class="require_alert" >'
+ ' *' + mbe
+ ' </span>'
);
}
can = 'no';
}
}
take = '';
});
if (can !== 'no') {
if (form_id !== 'vendor_pay') {
$.ajax({
url: form.attr('action'), // form action url
type: 'POST', // form submit method get/post
dataType: 'html', // request type html/json/xml
data: formdata ? formdata : form.serialize(), // serialize form data
cache: false,
contentType: false,
processData: false,
beforeSend: function () {
console.log(formdata);
var buttonp = $('.enterer');
buttonp.addClass('disabled');
buttonp.html(working);
},
success: function () {
ajax_load(base_url + '' + user_type + '/' + module + '/' + list_cont_func + '/' + extra, 'list', 'first');
if (form_id == 'vendor_approval') {
noty = enb_ven;
}
iziToast.show({
color: 'dark',
icon: 'fa fa-info',
title: 'Bilgi',
message: 'İşlem Başarılı!',
position: 'topCenter', // bottomRight, bottomLeft, topRight, topLeft, topCenter, bottomCenter
progressBarColor: 'rgb(0, 255, 184)',
/*onOpening: function(){
setTimeout(function(){
window.location.reload(1);
}, 5000);
console.log('Page Refresh!');
},
onClosing: function(){
// console.log('goodbye');
}*/
});
$('.bootbox-close-button').click();
('form_submit_success');
other_forms();
},
error: function (e) {
console.log(e)
}
});
} else {
//form.html('fff');
form.submit();
//alert('ff');
return false;
}
} else {
if (form_id == 'product_add' || form_id == 'product_edit') {
var ih = $('.require_alert').last().closest('.tab-pane').attr('aria-labelledby');
$("[id=" + ih +"]").click();
}
$('body').scrollTo('#scroll');
return false;
}
}
The error message always returns positive.

after run the validation, you need specify the array to be validated
public function save(){
$data = array();
$data['title'] = $this->input->post('title');
$data['description'] = $this->input->post('description');
$data['sale_price'] = $this->input->post('sale_price');
$data['purchase_price'] = $this->input->post('purchase_price');
$data['add_timestamp'] = time();
$this->form_validation->set_rules("title", "Title", "required|trim|is_unique[product.title]");
$this->form_validation->set_rules("description", "Description", "required|trim");
$this->form_validation->set_rules("sale_price", "Price", "required|trim");
$this->form_validation->set_message(
array(
"required" => "<b>{field}</b> is not null.",
'is_unique' => 'A %s content has already been added in thistitle.!'
)
);
$this->form_validation->set_data($data);
$validate = $this->form_validation->run();
You have to call the set_data() method before defining any validation rules.
