Взаимодействие с глобальными объектами Joomla

рейтинг: 9.2/10, голосов: 18

Преобразуем пример модуля Hello World! Для этого просто впишем новый php код в соответствующий файл.

<?php
    defined('_JEXEC') or die('Restricted access');
    $user = JFactory::getUser();
    if ($user->guest) {
        echo "<p>Добро пожаловать!</p>";
    } else {
        echo "<p>Имя пользователь: $user->username</p>";
        echo "<p>Пользователь: $user->name</p>";
        echo "<p>E-mail: $user->email</p>";
    }
?>

JFactory - это один из основных классов Joomla, содержащий в себе методы для вызова различных глобальных объектов. В данном примере он возвращает ссылку на объект класса JUser. Выведем с помощью модуля все возможные свойства о пользователе

<?php
    defined('_JEXEC') or die('Restricted access');
    $user = JFactory::getUser();
    print "\n Текущий пользователь \n";
    foreach ($user as $key => $value) {
        if (is_string($value)) {
            print "<p> Свойство пользователя $key = $value</p>\n";
        } else {
            print "<p> Свойство $key - это не строка</p>\n";
        }
    }
?>

Функция is_string() здесь необходима для того чтобы выводить только строковые свойства объекта. С помощью цикла foreach мы перебираем все свойства класса.

В качестве дополнительного примера попробуем использовать класс JURI.

<?php
    defined('_JEXEC') or die('Restricted access');
    $uri = JFactory::getURI();
    print "\nТекущий URI Запрос\n";
    foreach ($uri as $key => $value) {
        if (is_string($value)) {
            print "<p> Свойство $key = $value </p>\n";
        } else {
            print "<p> Свойство $key - не строка </p>\n";
        }
    }
?>

А вот еще один пример с использованием класса для формирования даты и времени - JDate:

<?php
    defined('_JEXEC') or die('Restricted access');
   
    // Получаем дату
    $date = JFactory::getDate();
 
    // Вызов метода toMySQL
    $datemysql = $date->toMySQL();
    echo "\n<p> Дата представлена в формате базы данных MySQL $datemysql </p>\n";
 
    // Используем метод класса toUNIX
    $dateunix = $date->toUNIX();
    echo "\n<p> Текущая дата в UNIX формате - $dateunix </p>\n";
 
    // Используя метод toFormat, преобразуем текущую дату к желаемому виду.
    $datestr = $date->toFormat ('%H:%M:%S - %d %b %Y');
    echo "\n<p> Текущая дата $datestr </p>\n";
 
    // используя внутренний метод _monthToString переведем номер месяца в слово
    echo "\n<p>" . JDate::_monthToString(4) . " or " . $date->_monthToString(4) . "</p>\n";
?>

Hey there! I just wanted to ask if you ever have any
trouble with hackers? My last blog (wordpress) was hacked and
I ended up losing months of hard work due to no back up.
Do you have any methods to protect against hackers?

being provided, however rather search out independent evaluations
on the model and provider in question.

desired results more efficiently and effectively, making essentially the most out of their Anavar
cycle. It is essential to acknowledge that repeated and extended use
