The following code shows how to validate an email with Joomla API
|
1 2 3 4 5 6 |
jimport('joomla.mail.helper'); $error = false; if (! $email || ! JMailHelper::isEmailAddress($email)) { $error = JText::sprintf('Email Corect', $email); JError::raiseWarning(0, $error); } |
Here below the code for a YES/NO radio button option suitable for example for published option in your table records:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<field name="fieldname" type="list" label="COM_COMPONENT_FIELD_FIELDNAME_LABEL" description="COM_COMPONENT_FIELD_FIELDNAME_DESC" class="inputbox" required="true" size="1" default="1"> <option value="0">JNO</option> <option value="1">JYES</option> </field> |
YES is the default option in this specific case.
The following code illustrates how to access groups an user is subscribed with Joomla ACL. Groups ids are returned in an array
|
1 2 3 4 5 6 7 |
$user = JFactory::getUser(); $userId = $user->id; jimport( 'joomla.access.access' ); $groups = JAccess::getGroupsByUser($userId); print_r($groups); |
To test the code, do not forget to lougout and login again should you have modified the user group from the back-end
Here below the code to programmatically obtain:
Access to Database Object
|
1 |
$db = JFactory::getDbo(); |
Access to User Object:
|
1 |
$user = JFactory::getUser(); |
Access to App Object:
|
1 |
$app = &JFactory::getApplication(); |
Access to Document Object:
|
1 |
$document = JFactory::getDocument(); |
You can obtain Joomla UserGroup id by name with the following code:
|
1 2 3 4 5 6 7 8 |
$db = JFactory::getDBO(); $query = $db->getQuery(true) ->select('a.id') ->from('#__usergroups AS a') ->where('a.title="'.$name.'"'); $db->setQuery($query); $gid = $db->loadResult(); |
If you want your component function to be accessed by your user prior to login programmatically you can use the following code:
|
1 2 3 4 5 6 7 8 9 10 |
public function toLogin($msg = "") { if (!$msg) $msg = JText::_('JGLOBAL_YOU_MUST_LOGIN_FIRST'); $app = &JFactory::getApplication(); $uri = JFactory::getURI(); $app->redirect('index.php?option=com_users&view=login&return=' . base64_encode($uri), $msg); return; } |
You can include the function in your helper class
helpers/yourcomponent.php
You can call the function in your MVC code with the following instructions:
|
1 2 3 4 5 |
$user = JFactory::getUser(); if (!$user->get('id')) { JLoader::register('yourcomponentHelper', JPATH_COMPONENT.'/helpers/yourcomponent.php'); yourcomponentHelper::toLogin(); } |
