After i follow joomla "Developing an MVC Component" Document until step 15- "Adding ACL"
Link - https://docs.joomla.org/J3.x:Developing_an_MVC_Component/Adding_ACL
everything works,
but i didn't see anything about create frontend category view,so i add a new view "category",here is my code:
in admin fields folder,i create a hellocategory.php
most code same with helloword,just change
protected $type = 'HelloCategory';
/**
* Method to get a list of options for a list input.
*
* #return array An array of JHtml options.
*/
protected function getOptions()
{
$db = JFactory::getDBO();
$query = $db->getQuery(true);
// custom
$query->select('#__categories.id as id,#__categories.title as category,#__categories.extension as exten');
$query->from('#__categories');
$query->where($db->quoteName('extension') . ' LIKE '. $db->quote('com_helloworld'));
// end custom
$db->setQuery((string) $query);
$messages = $db->loadObjectList();
$options = array();
view.html.php
class HelloWorldViewCategory extends JViewLegacy
{
/**
* Display the Hello World view
*
* #param string $tpl The name of the template file to parse; automatically searches through the template paths.
*
* #return void
*/
function display($tpl = null)
{
// Assign data to the view
$category = $this->get('Item');
// Check for errors.
if (count($errors = $this->get('Errors')))
{
JLog::add(implode('<br />', $errors), JLog::WARNING, 'jerror');
return false;
}
// Display the view
parent::display($tpl);
}
}
default.xml
<layout title="Category">
<message>category</message>
</layout>
<fields
name="request"
addfieldpath="/administrator/components/com_helloworld/models/fields"
>
<fieldset name="request">
<field
name="id"
type="hellocategory"
label="COM_UNOFD_UNOFD_FIELD_GREETING_LABEL"
description="COM_UNOFD_UNOFD_FIELD_GREETING_DESC"
/>
</fieldset>
</fields>
default.php
<?php var_dump($category); ?>
nothing output,
is there anything about create category document or sample online?i tried google for solution four days,but still no idea, or the only way is get data from database?
Closed,
because i found Joomla stackExange,thanks!
the question move to

I have created a model and added the $has_many for selecting multiple products. This is working fine but I am unable to make the selected products sortable by drag and drop. I know this is possible I have seen it. But I am unable to find anything in the documentation that shows how to get this done. Here is my model:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
require_once(FUEL_PATH.'models/Base_module_model.php');
/**
* This model handles setting up the form fields for our contact form
*
*/
class Products_category_model extends Base_module_model {
public $required = array('name', 'published');
public $has_many = array('products' => array(FUEL_FOLDER => 'Products_model'));
function __construct()
{
parent::__construct('w_product_categories');
}
/*
This will provide the list of records for display in the Admin Panel
Note how the "excerpt" will display, but truncated
Because we are using some MySQL functions in our select statement,
we pass FALSE in as the second parament to prevent CI auto escaping of fields
*/
function list_items($limit = null, $offset = null, $col = 'name', $order = 'asc', $just_count = false)
{
$this->db->select('id, name, published', FALSE);
$data = parent::list_items($limit, $offset, $col, $order);
return $data;
}
function form_fields($values = array(), $related = array())
{
$fields = parent::form_fields($values, $related);
return $fields;
}
}
class Product_category_model extends Base_module_record {
}
So it is very simple I discovered. I added this in the form fields function:
// Makes the has many drag and drop sortable.
$fields['products']['sorting'] = TRUE;
$fields['products']['after_html'] = "<div style=\"clear:both;font-style:italic\">NOTE: you can sort selected product to your choosing by clicking on the product and then dragging it into the desired placement in the list</div>";
With lumen, I have the problem that this is always 1, also when I go to /artikel?page=2:
LengthAwarePaginator::resolveCurrentPage();
the complete code:
<?php namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Support\Collection;
class ArtikelController extends Controller {
public function index()
{
$dir = '../resources/views/artikel/';
$files = array_diff(scandir($dir), array('..', '.'));
$artikel = array();
foreach($files as $k => $v)
{
$id = substr($v,0,1);
$artikel[$id]['id'] = $id;
$artikel[$id]['name'] = substr($v,0,strpos($v,'.blade.php'));
}
//Get current page form url e.g. &page=6
$currentPage = LengthAwarePaginator::resolveCurrentPage();
#dd($currentPage);
//Create a new Laravel collection from the array data
$collection = new Collection($artikel);
//Define how many items we want to be visible in each page
$perPage = 2;
//Slice the collection to get the items to display in current page
$currentPageResults = $collection->slice($currentPage * $perPage, $perPage)->sortByDesc('id')->all();
//Create our paginator and pass it to the view
$paginatedResults = new LengthAwarePaginator($currentPageResults, count($collection), $perPage);
$paginatedResults->setPath('artikel');
return view('artikel', ['artikel' => $paginatedResults]);
}
I can't find the mistake. What could be the reason? (I have also updated to "laravel/lumen-framework": "5.1.*")
You can use this simple way to get your current page:
$currentPage = (int) app('request')->get('page', $default = '0');
I would like to have joomla automatically re-index all the articles that are in a certain category (and subcategory) without indexing the rest. I am not looking for a cron job. I want joomla to do this when I hit the indexing button.
In other words, all the articles that are not in that particular category or its child subcategories should not be indexed and thus not show up in the search results.
EDIT (more info): This is for a specific site where I know the category id(s). I should probably also add that it is a bilingual site, the search module is appearing and indexing twice on the same page for each language. I.e. it indexes and appears on the English 'blog' page and the German 'blog' page.
Is this possible or do I need to manually delete the indexed files I don't want to show up?
EDIT: The discover tool is not working, here is the xml file to try and find out why.

I added the whole thing, just search for "where" to find the part that I changed. Everything else I did not touch.
Oh I think you are looking at the xml not the php.
// Check if we can use the supplied SQL query.
$query = $query instanceof JDatabaseQuery ? $query : $db->getQuery(true)
->select('a.id, a.title, a.alias, a.introtext AS summary, a.fulltext AS body')
->select('a.state, a.catid, a.created AS start_date, a.created_by')
->select('a.created_by_alias, a.modified, a.modified_by, a.attribs AS params')
->select('a.metakey, a.metadesc, a.metadata, a.language, a.access, a.version, a.ordering')
->select('a.publish_up AS publish_start_date, a.publish_down AS publish_end_date')
->select('c.title AS category, c.published AS cat_state, c.access AS cat_access');
If you want to exclude category 7 add
$query->where('a.catid <> 7');
after the last select.
Update ... or if you only want catgory 7
$query->where('a.catid = 7');
or if you only want category 7 and its children you would use IN ( comma separated list ).
Update
so this is what i'm getting for the generated query
SELECT a.id, a.title, a.alias, a.introtext AS summary, a.fulltext AS body,a.state, a.catid, a.created AS start_date, a.created_by,a.created_by_alias, a.modified, a.modified_by, a.attribs AS params,a.metakey, a.metadesc, a.metadata, a.language, a.access, a.version, a.ordering,a.publish_up AS publish_start_date, a.publish_down AS publish_end_date,c.title AS category, c.published AS cat_state, c.access AS cat_access, CASE WHEN CHAR_LENGTH(a.alias) != 0 THEN CONCAT_WS(':', a.id, a.alias) ELSE a.id END as slug, CASE WHEN CHAR_LENGTH(c.alias) != 0 THEN CONCAT_WS(':', c.id, c.alias) ELSE c.id END as catslug,u.name AS author
FROM a1pbr_content AS a
LEFT JOIN a1pbr_categories AS c ON c.id = a.catid
LEFT JOIN a1pbr_users AS u ON u.id = a.created_by
WHERE a.catid = 31
And that does give me just articles with catid of 31.
WHen you are indexing are you using the index button or doing it on save?
I am just playing around with the microFramework Slim + Twig template Engine. But actually passing an array in render method.
SomeOne help me to solve the error.
running in my local environment using XAMPP
Below is my code in index.php
<?php
/* Require and initialize Slim and Twig */
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
require 'Views/Twig/lib/Twig/Autoloader.php';
Twig_Autoloader::register();
$app = new \Slim\Slim(array(
'view' => new \Slim\Extras\Views\Twig(),
'templates.path' => './Templates'
));
/* Application routes */
$app->get('/', function () use($app) {
$pageTitle = 'hello world';
$body = 'sup world';
$app->render('index.php',array('title' => $pageTitle, 'body' => $body));
});
/* Run the application */
$app->run();
and below is the error am getting
Slim Application Error
The application could not run because of the following error:

Your resolution is an overhead. Better way is to pass $this->all(), which will return an array of set's key-value data, as an argument for $template->render() method.
public function render($template)
{
$env = $this->getEnvironment();
$template = $env->loadTemplate($template);
return $template->render($this->all());
}
Before April $this->data was an array but now it is a Set so that's why your problem occurred.
Unfortunately i have to answer my question.
I have just did a little hack in the Twig.php(in slim extras) and introduced a new function called ObjectToArray and now it works
function objectToArray( $object ) {
$array=array();
foreach($object as $member=>$data)
{
$array[$member]=$data;
}
return $array;
}
so my custom Twig.php files looks something like this

$array[$member]=$data;
}
return $array;
}
}
I think it should work without the above modification.
If you do have find any better solution , let me know
This will solve the problem!
function objectToArray($object){
if (!is_object($object) && !is_array($object)) {
return $object;
}
if (is_object($object)) {
$object = get_object_vars($object);
}
return array_map('objectToArray', $object);
}
I have a form build from the kohana framework which should send an email.
when I press the "send" button, everything seems to work fine...no error messages...but no email turns up!
If I can´t see anything in firebug..where can I look?
the application logs state
"error: Missing i18n entry contact.captcha.valid for language en_US"
but I don´t know how to get to the bottom of the problem..any help welcome..
yours,
Rob
Ill try and find out which version im using.....the application is the latest version of Ushahidi (2.2.1) www.ushahidi.com

From the little details provided I think your site uses the I18n library from Kohana for internationalization of the site. The other option is your site use Kohana messages for showing form errors.
The Validation class uses the __() function internally when generation validation errors. I think you don't have a message for key valid specified in APPPATH/messages/contact/captcha.php.
You should try to investigate more on how the form is processed and whether some validation errors are being generated. There might be an error in the captcha validation and despite it seem there is no error, there might be and just the error message could not be shown.

My problem has been solved!
My Email server was not set up properly. I resolved the postfix issue and now the comments form is working as it should,
thanks to all who answered,
