AJAX проверка логина при регистрации
рейтинг: 5.5/10, голосов: 4
Для того чтобы сделать AJAX проверку понадобиться серверная часть PHP и клиентская JavaScript. Файлы ядра Joomla при этом затрагиваться не будут. Данный пример рассматривается на стандартном шаблоне Beez 2.0, поэтому он может не работать на других шаблонах. Но суть останется та же.
Серверная часть
Для проверки существования логина пользователя нужно делать запрос в БД. Для этого можно использовать свой контроллер. Так как этот пример будет рассматривать стандартную регистрацию, соответственно контроллер должен быть в компоненте «com_users». Создадим файл со следующим содержанием:
<?php
defined('_JEXEC') or die;
jimport('joomla.application.component.controller');
/**
* Класс для AJAX проверок
*
* @package Joomla.Site
* @subpackage com_users
* @since 1.7
*/
class UsersControllerCheck extends JController
{
/**
* Метод проверки имени пользователя
*/
public function name()
{
// проверка значения сессии
JRequest::checkToken('get') or jexit(JText::_('JINVALID_TOKEN'));
$name = JRequest::getVar('name', null, 'GET');
if ($name) {
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('id');
$query->from('#__users');
$query->where('username = '. $db->quote($name));
$db->setQuery($query);
if ($db->loadResult()) {
die('логин занят');
} else {
die('логин свободен');
}
}
}
}
В этом файле собственно и будет происходить проверка логина пользователя. На вход должны поступать две переменные — имя пользователя и значение сессии. Остается написать клиентскую часть, которая будет отправлять эти данные.
Клиентская часть
В данном примере будет рассмотрен пример на mootools. Переопределите макет регистрации «components/com_users/views/registration/tmpl/default.php» в шаблоне и добавьте в него следующий JavaScript:
<script type="text/javascript">
<!--
window.addEvent("domready", function(){
document.id("jform_username").addEvent("blur", function(){
//проверка на корректность заполнения поля
//стандартная валидация добавляет class invalid,
//если поле заполнено неправильно.
var regex=/invalid/g;
if (regex.test(this.get('class')) || this.value.length < 2) return;
//получаем значение сессии из формы
//Элемент с именем сессии
//В данном случае это будет последний input в div-e
var form = this.getParent('form');
var inputs = form.getChildren('div input');
var s = inputs[inputs.length-1].name;
//удаляем элемент если установлен
if(this.getNext('span')) this.getNext('span').destroy();
//создаем новый элемент
var myElement = new Element('span', {'style':'margin-left:10px'});
myElement.inject(this, 'after');
//создаем AJAX запрос
var myRequest = new Request({
url: 'index.php?option=com_users&task=check.name&format=raw',
method: 'get',
onRequest: function(){
myElement.set('text', 'проверка логина');
myElement.addClass('ajax-loader');
},
onSuccess: function(responseText){
myElement.removeClass('ajax-loader');
myElement.set('text', responseText);
if (responseText == 'логин занят') {
myElement.getPrevious('input').addClass('invalid');
}
},
onFailure: function(){
myElement.set('text', 'Запрос не удался');
}
});
//посылаем запрос с данными
myRequest.send('name='+this.value+'&'+s+'=1')
})
})
//-->
</script>
Для «прелооадера» AJAX, загрузите какую-нибудь картинку в директорию «images» в шаблоне, например «ajax-loader.gif». И добавьте в свой файл стилей CSS, примерно следующие строки:
.ajax-loader {background:url(../images/ajax-loader.gif) no-repeat left;padding-left:20px;}
По желанию, этот пример можно подкорректировать под свои нужды шаблона, путем небольшой правки JS и CSS.
После этих манипуляций при регистрации пользователя, в форме регистрации должны добавиться изменения. А именно, после того как фокус уйдет с поля «Логин» в форме, данное поле не будет пустым и будет соответствовать требованиям стандартной JS проверки. Рядом с этим полем появиться новый элемент «span». В котором будет отображаться результат проверки логина пользователя.
Кинулся попробовать, но с ходу не получилось. Можно по подробнее описать действия?
пишет запрос не удался.
That is a good tip particularly to those fresh to the blogosphere.

Hi there this is kinda of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML.
I'm starting a blog soon but have no coding experience so I wanted to get guidance from someone with experience.
Any help would be greatly appreciated!

Good day! This is kind of off topic but I need some help from an established blog.

If so how do you protect against it, any plugin or anything you can advise?

I have been browsing online more than three hours today,
yet I never found any interesting article like yours. It's pretty worth enough for me.
In my view, if all webmasters and bloggers made good content as
you did, the net will be much more useful than ever before.

Online doctor consultation refers to the practice of consulting with
a healthcare professional over the internet, through video calls, phone calls,
or even text-based messaging platforms.
This form of consultation allows patients to discuss their medical concerns, receive
advice, and get a prescription if necessary without
physically visiting a doctor's office or clinic.
It has become increasingly popular, especially with
the advancements in telemedicine technology and the convenience it offers.
Some advantages of online doctor consultation include:
