Group by Query help from multiple tables

Hello,

I need help in a query from multiple tables.

Here are the table names:-

products 
images (for product's images)
users

  1. I need the query to return result as 4 products per user but maximum 3 users.
  2. and calculate the total number of products per user.
As show in the picture:-
[Image: RcS8D3s.png]


Here is the query I have been trying:-

Code:
public function random_three_sellers(){
   $this->db->select(
     'p.id as p_id, p.slug as p_slug, p.title as p_title, p.user_id as p_uid, p.status as p_status,
     u.id as u_id, u.username as u_name, u.slug as u_slug, u.email_status as u_estatus, u.banned as u_ban,
     i.product_id as i_pid, i.image_small as i_ism
     ');
   $this->db->where('p.status', 1);
   $this->db->from('products p');
   $this->db->limit(12);
   $this->db->join('images i','i.product_id = p.id', 'left');
   $user_array = array('u.banned' => 0 , 'u.email_status' => 1);
   $this->db->where($user_array);
   $this->db->join('users u','u.id = p.user_id', 'left');
   $this->db->group_by('p_uid');
   $query = $this->db->get();
   // var_dump($query);
   // die();

   if ($query->num_rows() > 0) {
     return $query->result_array();
   }else{
     return false;
   }
 }
 
3. Is it possible to add total number of followers per user. This data is in another table named "followers" , the column is "following_id"

4. Finally, how to show them in the view's loop?

Please ask me if any more info is required for the solution.


Regards.

Automatic assignment of 0777 access permissions

You can use the module installer from the Yii framework to copy files and set access permissions to files and directories. It is well suited for this task, for it is an independent package that does not require the Yii framework, nor any other libraries.

Example of composer.json configuration:

PHP Code:
"require": {
    "yiisoft/yii2-composer": "^2.0" 
}, 
"scripts": {
    "post-create-project-cmd": [
        "yii\\composer\\Installer::postCreateProject"
    ]
}, 
"extra": {
    "yii\\composer\\Installer::postCreateProject": {
        "copyFiles": [
            {
               "environment/.env": ".env" 
            }
        ], 
        "setPermission": [
            {
                "writable/cache": "0777",
                "writable/debugbar": "0777",
                "writable/logs": "0777",
                "writable/session": "0777",

email send error

I developing a website, where in an admin page have a button which processing an email send (to admin).

This is the configuration:


PHP Code:
   $this->load->library('encrypt');
    $config = array(
        'protocol' => 'smtp', // 'mail', 'sendmail', or 'smtp'
        //'useragent' => 'CodeIgniter',
        'smtp_host' => 'smtp.mail.yahoo.com',
        'smtp_port' => 465,
        'smtp_user' => '****',
        'smtp_pass' => '****',
        'smtp_crypto' => 'ssl', //can be 'ssl' or 'tls' for example
        'mailtype' => 'html', //plaintext 'text' mails or 'html'
        'charset' => 'iso-8859-1',
        'wordwrap' => TRUE,
    );
    $this->load->library('email', $config); 

I try with different configurations:
  • gmail with SSL, with TLS, with different 'smtp_host' like with and without ssl://
  • different gmails with @gmail.com and with another one which is not @gmail.com
  • yahoo mail with ssl
  • different PHP versions like 5.6 and 7.1
  • enable less secure apps in gmail/yahoomail
And this is the function:

PHP Code:
 public function send_email(){
    $from = $this->config->item('smtp_user');
    $to = '****';

    $this->email->from($from);
    $this->email->to($to);
    $this->email->set_newline("\r\n");
    $this->email->subject('szerkesztési jog igénylése');
    $this->email->message(
      'Tisztelt adminisztrátor!\r\n
      \r\n
      Egy felhasználó szerkesztési jogot szeretne igényelni a Faipari szakszótárhoz\r\n
      Kérjük jelentkezz be, és bíráld el a szerkesztési jogát az igénylőnek'
    );

    if ($this->email->send()) {
      $this->session->set_flashdata('uzenet', 'Sikeres szerkesztési jog igénylés');
      redirect('pages/user', $data);
    } else {
      show_error($this->email->print_debugger());
    }
  } 
I got different error codes for different cases, but nothing made solution after few hours google search and reading threads.

Updating Model with a unique field?

Hi guys

Just working on an update in the model controller and have hit a snag.

I have setup one of the fields as unique, when I try an update, it always fails, unless that particular field has changed and is still unique.

Is there a way to temporarily turn off the unique check based on if it has changed or not? because I may not want to change that field.

Thanks

Greetings, 

I'm continuing some existing projects referencing images via Javascript files e.g.
var images=["<img src='/images/chicken.png'>","<img src='[b]/images/pig.png'>"][/b]
Is it possible to reference these directly from Javascript files located in the assets folder i.e. C:\xampp\htdocs\game\assets\images just for demo purposes, not best practice.

Where to place functions that work with database

Hi guys,

I'm sure this is a very remedial question, but I'm not quite sure what is best-practice here.

I have one model for each table in my database, and I have a controller that does a lot of calculations involving data from many tables.  I'd like to create a bunch of functions to make my code cleaner (and hopefully take some of the code out of the controller).

I thought to use helper functions, but I wasn't sure how to access database objects in the helper functions; since my "use" statements are in the controller.

Thanks,
Phil

POST input is empty if contains accented characters.

Hi there folks.

I'm trying to debug a CI app to a friend of mine. The issue is that $this->input->post('name'); is empty if a accented character is sent.
Eg.:

If I send the name as Testing, then the value of $this->input->post('name'); is also Testing.
But if I send the name as Accentuátion (or anything with special accent characters), the the value of $this->input->post('name'); is "" (empty).

Any clue of what might be causing this issue of how to fix it?

Help with domain xfer stuff

Hi all,

I'm building a website for a guy and currently we are hosting on an instance on Amazon Lightsail to keep costs down.

The client has purchased a couple domains and they are parked over on GoDaddy.   I'd like to transfer them to AWS both from a management standpoint but also have them point to our Lightsail instance.

I also would like to setup AWS Simple Email Service to work with the domain so our site can email out and we can receive inbound emails at our domain.com.   

Quite frankly I find the transfer process to Amazon to be a little over my head.  Wondering if there is someone that can lend a little help in getting this done.  I think the client is willing to pay a little but we are on a tight budget.

Please email me at:  markholbrook@fastmail.net

If you can help.

Mark
