I have a view and it is responding fine for the filters I give. However when I run this multiple times in a for loop in my module, I get the same response for whichever filter I apply.
I searched the web and found code to turn off view caching. I have also disabled views data caching from structure->views->settings->advanced. But that is not working.
Below is the example code:
foreach ($term_ids as $term_id) {
$view2 = test_generate_view($view_name, $display_handler, $page, $count, $term_id);
echo "<pre>";
print_r($view2);
}
function test_generate_view($view_name, $display_handler, $page, $count, $term_id = null) {
$view = views_get_view($view_name, TRUE);
$view->set_display($display_handler);
if (!empty($term_id)) {
$term_item = $view->get_item($display_handler, 'filter', 'field_ref_issue_target_id');
$term_item['value']['value'] = $term_id;
$view->set_item($display_handler, 'filter', 'field_ref_issue_target_id', $term_item);
}
$view->init_pager();
$view->pager['items_per_page'] = $count;
$view->pager['use_pager'] = true;
$view->display_handler->options['use_pager'] = true;
$view->set_items_per_page($count);
$view->pager['current_page'] = $page;
$view->is_cacheable = FALSE;
$view->pre_execute();
$view->execute();
return $view;
}
If I don't run them in a loop and try separately for every term-id its working fine. But if I run them in a loop like above, the output is same for any term-id.
The code doesn't look so bad and because the filter changes, the caching should deliver a different result even if turned on. Because the code is working without the loop, maybe you should look into that. is $term_ids really an array of integer values or an array of term objects? If so, the function call would fall back to default which is null for term_ids and would not add a filter.
By the way: You should have a look at contextual filters which you can use really easily.

I managed to fix a problem but I dont understand why it worked and it seems glitchy, so I wonder if someone could explain me. I wanted to get articles from my article models and retrieve that in angular, and I had a hard time getting the subkeys with "featured_images" from octobercms. I found a workaround, like this, in my laravel controller:
public function test()
{
$result = Article::take(4)->get();
$listarr = array();
foreach($result as $article) {
$listarr[] = $article;
foreach($article->featured_images as $image) {
}
}
return response()->json($listarr);
}
But if I remove the foreach($article->featured_images as $image) { } section I dont get the "featured_images" with $listarr. And just using $result doesnt give me those keys if i return response()->json($result);
This is how i want it: http://pastebin.com/MJvnbrrn
But not like this, without "featured_images": http://pastebin.com/1Xa3n9fD
And i get it how i want it if i do that forreach both on $result as $article and only if i then use foreach($article->featured_images as $image) { }. I think I am confused and that there is a more elegant way to this but multidimentional arrays is hard for me.
The foreach call is loading the relationship and therefore including it in the subsequent JSON data. The following call will preload the relationship, using eager loading, and should include it in the same way.
Article::with('featured_images')->take(4)->get();
Alternatively you can use "lazy eager loading"
$result = Article::take(4)->get();
$result->load('featured_images');
I am using solarium to implement a solr search. I need to index my files into solr. I am using the following code to do so.
require('init.php');
use Solarium\Plugin\BufferedAdd\Event\Events;
use Solarium\Plugin\BufferedAdd\Event\PreFlush as PreFlushEvent;
use Solarium\Plugin\BufferedAdd\Event\PostCommit as PostCommitEvent;
/////////////////This function adds the knowledge maps to solr//////////////////////////////
$results_index = query(" select indexed_id from update_solr WHERE table_name='knowledgemaps'");
$results = query(" select m_id,k_id, m_title, m_des from knowledgemaps WHERE k_id>{$results_index[0]['indexed_id']}");
$client = new Solarium\Client($config);
$buffer = $client->getPlugin('bufferedadd');
$buffer->setBufferSize(10);
for($i=0;$i<count($results);$i++) {
// also register an event hook to display what is happening
$client->getEventDispatcher()->addListener(
Events::PRE_FLUSH,
function (PreFlushEvent $event) {
echo 'Flushing buffer (' . count($event->getBuffer()) . 'docs)<br/>';
}
);
// Create a document
$doc = array();
$doc["map_id"]=$results[$i]["m_id"];
$doc["user_id"]=$results[$i]["k_id"];
$doc["map_title"]=$results[$i]["m_title"];
if(isset($results[$i]["m_des"])&&is_null($results[$i]["m_des"])){
$doc["map_des"]=$results[$i]["m_des"];
}
$buffer->createDocument($doc);
}
$buffer->flush();
When I execute the code i do not get any errors. It give the number of flushes documents as correct. But no data is getting indexed in solr.
Is there some additional code required to index the information
You need probably still need to commit the changes, you can do this by replacing the last flush call with commit.
I've two controllers one is "Upload" which deals with images uploads and other is "Page" whid deals with the creation of pages of CMS now if in my "Upload" controller I load both the models i.e 'image_m' which deals with image upload and "page_m" which deals with the pages creation I've highlighted the relevant code my problem is if I access the variables in the view
$this->data['images'] = $this->image_m->get(); sent by this I can access in foreach loop as "$images->image_title, $images->image_path" etc
But the variable sent by this line ***$this->data['get_with_images'] = $this->page_m->get_no_parents();*** as $get_with_images->page_name, $get_with_images->page_id etc produces given error
A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: upload/index.php
Line Number: 20
what is the difference between these two access levels one for $image & other for $get_with_images because I can only access its values as $get_with_images
class Upload extends Admin_Controller {
public function __construct() {
parent::__construct();
***$this->load->model('image_m');
$this->load->model('page_m');***
}
public function index($id = NULL) {
//var_dump($this->data['images'] = $this->image_m->get_with_images());
//$this->data['images'] = $this->image_m->get_with_images();
***$this->data['images'] = $this->image_m->get();***
$this->data['subview'] = 'admin/upload/index';
if ($id) {
$this->data['image'] = $this->image_m->get($id);
count($this->data['image']) || $this->data['errors'][] = 'Page Could not be found';
}
$id == NULL || $this->data['image'] = $this->image_m->get($id);
/*this calls the page_m model function to load all the pages from pages table*/
***$this->data['get_with_images'] = $this->page_m->get_no_parents();***
You are not posting all your code so its hard to tell but is it because you used $this-> in the controller, but you haven't done the same thing in the view?
In this case i would recommend not using $this-> because its not necessary. Also its much better to check for errors etc when you call the model so do something like
if ( ! $data['images'] = $this->image_m->get($id) ) {
// Failure -- show an appropriate view for not getting any images
// am showing $data in case you have other values that are getting passed
$this->load->view( 'sadview', $data ); }
else {
// Success -- show a view to display images
$this->load->view( 'awesomeview', $data ); }
so we are saying if nothing came back - the ! is a negative - then show the failure view. Else $data['images'] came back, and it will be passed to the view. note i have not had to use $this-> for anything and it won't be needed in the view.
Would also suggest using separate methods - have one method to show all images and a separate method like returnimage($id) to show an image based on a specific validated $id.
====== Edit
You can access as many models as you want and pass that data to the View. You have a different issue - the problem is that you are waiting until the View to find out - and then it makes it more difficult to figure out what is wrong.
Look at this page and make sure you understand the differences between query results
http://ellislab.com/codeigniter/user-guide/database/results.html
When you have problems like this the first thing to do is make a simple view, and echo out directly from the model method that is giving you problems. Its probably something very simple but you are having to look through so much code that its difficult to discover.
The next thing is that for every method you write, you need to ask yourself 'what if it doesn't return anything?' and then deal with those conditions as part of your code. Always validate any input coming in to your methods (even links) and always have fallbacks for any method connecting to a database.
On your view do a var_dump($get_with_images) The error being given is that you are trying to use/access $get_with_images as an object but it is not an object.
or better yet on your controller do a
echo '<pre>';
var_dump($this->page_m->get_no_parents());
exit();
maybe your model is not returning anything or is returning something but the data is not an object , maybe an array of object that you still need to loop through in some cases.
I want to list the posts of a given user. It work but paginate is not accurate.
My code is the following
public function index($userid = null) {
if ($this->Post->exists($userid)) {
$this->set('posts',$this->Post->find('all',array('conditions'=>array('user_id'=>$userid))),
$this->paginate());
} else
{
$this->Post->recursive = 0;
$this->set('posts', $this->paginate());
}
The result give the correct list --> 3 posts, but the paginator display page number 1 and 2
Can you help me?
Thank you
Refer to the documentation
The code in the question is quite confused.
find
The find method only has two parameters:
find(string $type = 'first', array $params = array())
The third parameter (the result of calling paginate) isn't used and will be ignored - but it will setup the view variables for the pagination helper, based on the conditions used in the paginate call - there are no conditions being used.
It is not possible to paginate the result of a find call - to do so restructure the code to call paginate instead of find.
paginate
The paginate method is just a proxy for the paginator component - it can be used in several ways, this one (controller code example):
$this->paginate($conditions)
Is the most appropriate usage for the case in the question i.e. the complete action code should be similar to:
public function index($userId = null) {
$conditions = array();
if ($userId) {
$conditions['Post.user_id'] = $userId;
}
$this->set('posts',$this->paginate($conditions));
}
Note that logically, if a user id is requested that doesn't exist the response should be nothing - not everything.
I'm quite sure that conditions for paginate do now work that way.
If you want to set conditions for paginations you should do it as follows:
$this->paginate = array('conditions' => array('Post.user_id' => $userid)));
$this->set('posts', $this->paginate());
And yes, the result stored in $posts ( in view ) will be proper as you assigned proper find result to it, meanwhile you've paginated post model without any conditions whatsoever.
First off, you're checking to see if the post exists but using the $userid. Are you trying to see "if the user exists, get the posts for that user, or else get posts for ALL users"? As you have it right now, say you have the $userid = 159, but the max Post.id in your database is 28, then the condition is not being met because it is checking to see whether or not there is a Post with the id = 159 that exists, which it doesn't.
Second, your conditions are wrong. You are performing a find and then a paginate which are two separate queries. The conditions are being implemented on the find query but not the paginate but you are only displaying the find results.
public function index($userid = null) {
// setting recursive outside of if statement makes it applicable either way
$this->Post->recursive = 0;
// check if user exists
if ($this->Post->User->exists($userid)) {
// get posts for user
$this->set('posts', $this->paginate('Post', array('Post.user_id' => $userid));
}
else{
// get all posts
$this->set('posts', $this->paginate('Post'));
}
} // end index function
Please help, this is my first plugin I'm writing and I'm completely lost. I'm trying to write and update information in a table in a joomla database using my custom giveBadge() function. The functions receives two different variables, the first variable is the $userID and the second one is the digit 300 which I pass at the bottom of the class using giveBadge(300). At the same comparing the $userID in the Joomla database to ensure that the number 300 is given to the current user logged in the Joomla site.
Thanks in advance.
<?php
defined('JPATH_BASE') or die;
class plgUserBadge extends JPlugin
{
public function onUserLogin () {
$user =& JFactory::getUser();
$userID =& user->userID;
return $userID;
}
public function giveBadge ($userID, &$badgeID) {
// Get a db connection.
$db = JFactory::getDbo();
// Create a new query object.
$query = $db->getQuery(true);
// Fields to update.
$fields = array(
'profile_value=\'Updating custom message for user 1001.\'',
'ordering=2');
// Conditions for which records should be updated.
$conditions = array(
'user_id='.$userID,
'profile_key=\'custom.message\'');
$query->update($db->quoteName('#__user_badges'))->set($fields)->where($conditions);
$db->setQuery($query);
try {
$result = $db->query();
} catch (Exception $e) {
// Catch the error.
}es = array(1001, $db->quote('custom.message'), $db->quote('Inserting a record using insert()'), 1);
}
}
giveBadge(300); //attaches to $badgeID
?>
Here is not going well with your code:
You can drop the assign by reference in all your code (&) - you really don't need it, in 99% of the cases.
Use an IDE (for example Eclipse with PDT). At the top of your code you have & user->userID; Any IDE will spot your error and also other things in your code.
Study existing plugins to understand how they work. Here is also the documentation on plugins.
The method onUserLogin() will automatically be called by Joomla when the specific event is triggered (when your plugin is activated). Check with a die("My plugin was called") to see if your plugin is really called
inside onUserLogin() you do all your business logic. You are not supposed to return something, just return true. Right now your method does absolutely nothing. But you can call $this->giveBadge() to move the logic to another method.
