How can I make show the total number of members registered in Codeigniter?
I need model, controller, view codes.
I would appreciate if you help.
As you didn't give us more code and information though. I think you want to display the total number of users registered in your view, write this part of the code where you want to count the number.
<?php
$this->load->model('admindash_model');
$count_users = count($this->admindash_model->get());
print $count_users;
?>
I think this will going to help you. If you could understand and place
it properly.
Model:
public function get(){
$this->db->select('gorun');
$this->db->from('users');
$this->db->where('gorun', '0' );
return $this->db->count_all_results();
}
Controller:
public function admindash(){
$this->load->model("admindash_model");
$results = $this->admindash_model->get();
}

I have six models that I need to get in one instance in my controller. How can I do that?
I have my six models:
CommentaireCritique
CommentaireNews
CommentaireDossier
CommentaireEpisode
CommentaireSerie
CommentaireTrailer
They all have the same structure in my database, and I would like to show the latest comms on one single page. I don't know if it's possible to bind them in a single controller. I tried that, but it's not working.
public function index()
{
$comms = CommentaireCritique::all() && CommentaireNews::all()
&& CommentaireDossier::all() && CommentaireEpisode::all()
&& CommentaireSerie::all() && CommentaireTrailer::all()
->get();
return view('admin.commentaires.index', compact('comms'));
}
just after the namespace , before the class declaration
use yourAppNameSpace/modelName
There is no limits to the number of models you can instantiate in your controller as long as you declare them above correctly.I think what you need is way to merge the result of all the models if that is so, then you have to use the merge method, otherwise can you please clarify a little bit your question.
yes, you can retrieve them at one controller,
you're already halfway there, you should separate on different variable
public function index()
{
$comms = CommentaireCritique::all()
$news = CommentaireNews::all()
$dossier = CommentaireDossier::all()
$episodes = CommentaireEpisode::all()
$series = CommentaireSerie::all()
$trailers = CommentaireTrailer::all()
return view('admin.commentaires.index', compact('comms','news','dossier','episodes','series','trailers'));
}
if you want put them in one variable, you can use collection docs
All of the results from all() function returns laravel collections. So use concat() function to concatenate all those into one collection
public function index()
{
$coms = CommentaireCritique::all()
->concat(CommentaireNews::all())
->concat(CommentaireDossier::all())
->concat(CommentaireEpisode::all())
->concat(CommentaireSerie::all())
->concat(CommentaireTrailer::all());
return view('admin.commentaires.index', compact('comms'));
}
Controller
public function category($id = '') {
$offset=..;
$var = $this->pm->get_items_by_category($id,$offset,$start_row);
}
But in my view I have :
<li>Mobile</li>
I think I know what you are trying to say but it's not very clear.
Your link needs to pass the limit and offset as well as the id. So do something like this
<li>Mobile</li>
Then in your controller set up your function like this.
public function category($limit, $offset, $id){
}
If you give more info I can give better answer.
isn't this the right method to get Name of logged in customer?
<?php echo Mage::helper('customer')->getCustomer()->getName(); ?>
I have a website with live chat functionality. Yesterday I have been asked to pass email address and the name of the logged into the user into the Javascript Tracking variable code placed in the head section of the website. So that the operators could see who is on the website and whom are they talking to without any need to ask about their information.
So I passed the information from Magento into the Javascript code but now I see this very strange thing happening. For example,
If I am logged in with credentials Name = John Email =
john12#yahoo.com
Then This name and email variable values are changing with the change of pages. For example if I click on any product page the variable values which I am passing changes to some other user's information.
Name becomes Ricky Email becomes ricky23#gmail.com
this variable values are kept on changing back to john and from john to something else with the change of pages. So operator does not have any idea whom are they talking because the values are kept on changing. Also, user ricky or who ever it changes to also exist in the database. so it is picking up random person from the database.
This is what i did to pass the code to javascript. Please let me know if that is not the right code to pass the information. Please check the php code I am using to fetch information from Magento. Roughly, I receive incorrect value once in 5 times. Please provide some assistance. Thanks in advance.
<?php
$customer = Mage::getSingleton('customer/session')->getCustomer();
$email = $customer->getEmail();
$firstname = $customer->getFirstname();
$lastname= $customer->getLastname();
$name = $firstname . ' ' . $lastname;
?>
<script type="text/javascript">
if (typeof(lpMTagConfig) == "undefined"){ lpMTagConfig = {};}
if (typeof(lpMTagConfig.visitorVar) == "undefined"){ lpMTagConfig.visitorVar = [];}
lpMTagConfig.visitorVar[lpMTagConfig.visitorVar.length] = 'Email=<?php echo $email; ?>';
lpMTagConfig.visitorVar[lpMTagConfig.visitorVar.length] = 'Name=<?php echo $name; ?>';
</script>
I'm also attaching a snap shot
I'd be interested to hear how you're adding this code to the page? Is it in it's own block, or are you adding it to footer.phtml, or similar? If your adding to an existing block be sure to check the block caching settings of that template.
To confirm the caching hypothesis I'd ask the following:
Do you get the same name, all the time, on the same page? When you refresh the page, do you get the same name and email in the Javascript?
Does the problem persist with caching disabled?
This doesn't sound like a singleton problem at all. Each execution of the PHP script is isolated from the others, serving one page request. There's no chance of another customer's object moving between invokations of the script.
It is a matter of understanding the singleton pattern. If you call your code twice:
$customer_1 = Mage::helper('customer')->getCustomer()->getName();
$customer_2 = Mage::helper('customer')->getCustomer()->getName();
you get two different instances of the object. But... if one of them has already implemented a singleton pattern in its constructor or has implemented a singleton getInstance then both objects will actually point to the same thing.
Looking at the customer/helper/Data.php code you can see the function
public function getCustomer()
{
if (empty($this->_customer)) {
$this->_customer = Mage::getSingleton('customer/session')->getCustomer();
}
return $this->_customer;
}
That means that in one of the cases singleton is already implemented/called and in other one - not as the property is already set.
The correct way to work with quote/customer/cart in order to get always the correct data is always to use the singleton pattern.
So using this:
$customer = Mage::getSingleton('customer/session')->getCustomer();
always guarantee that you get the correct customer in that session. And as may be you know singleton pattern is based on registry pattern in app/Mage.php:
public static function getSingleton($modelClass='', array $arguments=array())
{
$registryKey = '_singleton/'.$modelClass;
if (!self::registry($registryKey)) {
self::register($registryKey, self::getModel($modelClass, $arguments));
}
return self::registry($registryKey);
}
and looking at app/Mage.php:
public static function register($key, $value, $graceful = false)
{
if (isset(self::$_registry[$key])) {
if ($graceful) {
return;
}
self::throwException('Mage registry key "'.$key.'" already exists');
}
self::$_registry[$key] = $value;
}
...
public static function registry($key)
{
if (isset(self::$_registry[$key])) {
return self::$_registry[$key];
}
return null;
}
you can see that Magento checks is it is already set. If so, Magento will either throw an Exception, which is the default behavior or return null.
Hope this will help you to understand the issue you face.
I have sorted this out. I have moved the code from footer.phtml to head.phtml and it's working fine now.Values are not changing anymore. If anyone know the logic behind please post and I will change my answer. So far this is working.
I'm trying to write a Magento (CE 1.4) extension to export order data once an order has been paid for. I’ve set up an observer that hooks in to the sales_order_invoice_save_after event, and that is working properly - my function gets executed when an invoice is generated. But I’m having trouble getting information about the order, such as the shipping address, billing address, items ordered, order total, etc.
This is my attempt:
class Lightbulb_Blastramp_Model_Observer {
public function sendOrderToBlastramp(Varien_Event_Observer $observer) {
$invoice = $observer->getEvent()->getInvoice();
$order = $invoice->getOrder();
$shipping_address = $order->getShippingAddress();
$billing_address = $order->getBillingAddress();
$items = $invoice->getAllItems();
$total = $invoice->getGrandTotal();
return $this;
}
}
I tried doing a print_r on all those variables, and ended up getting a lot of data back. Could someone point me in the right direction of getting the shipping address of an order?
Thanks!
Many Magento objects are based on Varien_Object, which has a method called getData() to get just the usually interesting data of the object (excluding the tons of other, but mostly useless data).
With your code you could either go for all the data at once:
$shipping_address = $order->getShippingAddress();
var_dump($shipping_address->getData());
or directly for specific single properties like this:
$shipping_address = $order->getShippingAddress();
var_dump(
$shipping_address->getFirstname(),
$shipping_address->getLastname(),
$shipping_address->getCity()
);
To understand how this works, I'd recommend to make yourself more familiar with the Varien_Object and read a bit about PHPs magic methods, like __call(), __get() and __set().
Try print_r($shipping_address->toArray());
I have a table of data from a database that I want to display on various pages of my website. Ideally, i would like to just have an include or something that will go off and get the data, and return the html table. The html and data will be identical everytime I need to use this.
I wanted to know the best way of doing this
Thanks
EDIT
If this helps, something similar to a Django "inclusion" custom tag...for any django developers reading
you need to pass the variable $data to the view method.
This is your code:
function load_my_view(){
$this->load->model('my_table');
$data['my_results'] = $this->my_table->my_data();
$this->load->view('my_view');
}
Please change it to this in order to load the $data into the view:
function load_my_view(){
$this->load->model('my_table');
$data['my_results'] = $this->my_table->my_data();
$this->load->view('my_view',$data);
}
You should use a function in a model to fetch the data you need. Your controller calls the model function and sends the returned information to a view. You don't need to use traditional php includes with Codeigniter. I recommend a review of the user guide. It's very good and will tell you all the basic stuff you need to know to develop with CI. But to get you started, you watn to use Models, Views, and Controllers. Your url will tell CI what controller and function inside that controller to run. If your url is
http://www.example.com/my_controller/load_my_view
Then CI will do what is inside the load_my_view function in the my_controller controller. function load_my_view in turn instantiates a model "my_table" and runs a database query, returns information that the controller sends to the view. A basic example follows:
Your model
class my_table extends CI_Model{
function my_data(){
$this->db->select('column_1,column_2,column_3');
$this->db->from('my_table');
$query = $this->db->get();
if($query->num_rows()>0){
$result = $query->result();
}
else{
$result = false;
}
return $result;
}
}
Your controller
class my_controller extends CI_Controller{
function load_my_view(){
$this->load->model('my_table');
$data['my_results'] = $this->my_table->my_data();
$this->load->view('my_view');
}
}
Your View
<ul id = "my_db_results">
<?php foreach($my_results as $result):?>
<li><?php echo $result->column_1." : ".$result->column_2." ( ".$result->column_3." )";?></li>
<?php endforeach;?>
</ul>
It looks like a good oportunity to use cache: http://codeigniter.com/user_guide/libraries/caching.html
Ok, so here is one thing that worked for me, but its definitely not perfect.
I created a view in which made a call to the model getting the data then put the data into a table. This way, I only have to include this view to put the table anywhere.
I understand this completely ruins the point of having a MVC framework, but hopefully it demonstrates what I want to do...and it works
