CodeIgniter AJAX JSON 验证器与表单验证

Question

我正在尝试使AJAX表单验证在CodeIgniter中工作。

如果您有相同的标题，请不要添加表单中的数据始终报告为成功，即使结果为负数也是如此。

我的逻辑有误吗？

保存控制器：

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;
}
}

错误消息始终返回正值。

运行验证后，您需要指定要验证的数组

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();

在定义任何验证规则之前，必须调用set_data()方法。
