CodeIgniter with PostgreSQL and PgBouncer in Transaction mode

Previously we used PostgreSQL 9 with PgBouncer in session mode, and with that was able to easily create a new record and get the last ID with db->insert_id('table', 'pk_column').

But the use of the Session mode of PgBouncer proved to be extremely problematic for us, with several operations per second, the Pool easily reached the capacity of connections, so we switched to PostgreSQL 12 with PgBouncer in Transaction mode.

One problem that has begun to occur with this mode is that using operations that require being in the same session does not work, not allowing to use CURRVAL, which is used by insert_id(), 

Example of Insert created by CodeIgniter 3:

Code:

INSERT INTO "table" ("column") VALUES ('ABC');
SELECT pg_get_serial_sequence('table', 'tableid') AS seq;
SELECT CURRVAL('public.table_tableid_seq') AS ins_id;

This code will trigger the error:

Quote:currval has not yet been defined this session

Is there any configuration that must be done in CodeIgniter to work with PgBouncer in transaction mode?

Hi all! I thought I posted about this one when I released the initial version, but I can't find the thread so maybe I forgot to? Either way, if you've never heard of Tatter\Files then you're in luck: it's better than ever!

Tatter\Files: File Uploads and Management
https://github.com/tattersoftware/codeigniter4-files

"Files" is a self-contained file management suite, with its own routes, model, controller, and view. Install via Composer, update your database, and voila! instant file management.
But it's better! The whole thing is modular and very configurable/extendable. Don't want just anyone to upload? No problem, adjust permissions for every CRUD action and route. Want to embed files in en existing page? No problem, requests respond to AJAX or you may load the view directly. See the README for all the things you could possibly configure.

A significant motivating factor for this version was to take advantage of the underlying packages and their powerful improvements: Tatter\Handlers, Tatter\Exports, and Tatter\Thumbnails. All these modules have been refactored to eliminate extra steps (like unnecessary migrations), apply full static analysis and unit tests, and fix a slew of bugs.

"Files" is better than ever, but there are bound to be bugs and missing features. I welcome your feedback here, or on the GitHub repo.

---

Quick Start:

1. Install with Composer: > composer require tatter/files
2. Migrate the database: > php spark migrate -all
3. Seed the database: > php spark dbeed "Tatter\Files\Database\Seeds\FileSeeder"
4. Start managing files: https://example.com/files

By default Files configures the "/files/" route and is set up in a loose dropbox mode where anyone can upload files and view existing versions. Permissions can be applied directly to the model with a simple chmod-style "mode" (e.g. 755), via controller filters, or with a whole authentication suite (like Myth:Auth).
The MVC portion of the module uses its Config file to adjust behavior, which you can copy into App and change as needed. Controllers/Files.php contains a number of helper methods that make it easy to extend, so your own "app/Controllers/Widgets.php" can extend "Tatter\Files\Controllers\Files" to make easy lists of widget files.

Override page cache functionality

Hi,

I would like to use the page cache with 

Code:

$this->cachePage(600);

However, it should never use the cache is the user is logged in on site. I can check this with 

Code:

if ($session->logged_in)

But it the page is already cached, it won't run any logic. So I don't know how to do a check before the cache is fetched. My first thought was to override the function cache in Common.php, but I don't think that would be enough?

Now I'm trying to override system/Cache/Handlers/FileHandler.php in get() and getItem(). It doesn't seem to work though. I followed the this guide: https://codeigniter.com/user_guide/exten...asses.html

Could be that the cache is not automatically run and I cannot override it this way.

Would it be possible to write my own cache handler?

I also tried emptying the cache on all requests when logged in, but it affects all users of course, and if multiple visitors are on site at the same times it get's messy.

Any ideas for me, on how to do conditional caching? It's ok if it does cache the page as long as the cached page is not returned when logged in.

Thanks

Hi everyone, I'm new with codeigniter. I have this problem. I have a western table with data and a view that shows everything. Procedural php code use when I wanted to generate an art director page I put the link followed by? :

director? id_regista = $ id_regista

then I went to the landing page and filled in the select with the recovery in GET. But here on codeigniter it doesn't work! I've tried several model-like things:

SOLUTION A:

Details VIEW:

                  echo "<h5><a href='index.php/western/regista/$id_regista/'>.$row->regia</a></h5>";

Details MODEL:

function regista()

  {

    $id_regista= $this->uri->segment(3);
    $query  = $this->db->select('*')
      ->from('western')
      ->where('id_regista', '$id_regista') // Condition
      ->get();
    return $query->result();
  }


___________________________________________________________________________________________________________

OR SOLUTION B

VIEW:    echo "<h5><a href='index.php/western/regista?id_regista=$id_regista'>.$row->regia</a></h5>";

Model:

  function regista1()

  {

    echo $this->input->get('$id_regista');

    $query = $this->db->query("SELECT * FROM western where 'id_regista' = '$id_regista'");

    if ($query->num_rows() == 0) {

      show_error('empty db!');
    } else {

      return $query->result();
    }
  }

but both solutions do not dynamically generate the corresponding director for me starting from the home director link.

How do I retrieve the parameter and fill the query to build the page since

    $id_regista = $_GET['id_regista'];

put in model don't work?

For either solution A or B use in the Western controller

    function regista()
        {
 

                $this->load->model('western_model');
                $data['result'] = $this->western_model->regista();
                $this->load->view('regista_view', $data);
        }


and I also bothered to insert in the index

$this->load->helper('url');

thanks in advance on some helpful tips to solve, I have tried everything but I can't solve the parameter capture problem either using GET or segment

I am trying to build a json representation of an array. My array is 

$request = array();
$request["registration.applicationId"] = $applicationID;
$requestJ = json_encode($request);  //convert the array into json

when I run this $requestJ becomes $requestJ = {"registration.applicationId":"32688330-1630-4e0d-a4de-8ae45c3ca527"}

but the documentation for the package I am using shows this as valid

Code:

{
  "registration": {
    "applicationId": "10000000-0000-0002-0000-000000000001",

Notice how the package's demo has a registration section while mine has registration.applicationId? How do I get json_encode to create a json like the sample?

I inherited a codeigniter website, and upgraded codeigniter. Figured out the controller files have to start with capital letters, and I got most of the routes and views working again. Except for the Admin portion of the site. The routes for this portion is not in the routes.php file, but in a different file. And the controllers is in a sub directory called admin, which I renamed to Admin. So even though there is for example an entry:

PHP Code:

$route['admin'] = 'admin/admin/index' 


When I go to /admin I get 404, and logs show:

Code:

404 Page Not Found: Admin/admin

I've even tried putting eg

PHP Code:

$route['admin/login'] = "admin/admin/login"; 


in the routes.php file, but I still see in the logs

Code:

404 Page Not Found: Admin/admin

even though:

Code:

$ grep admin config/routes.php
route['admin/login'] = "admin/admin/login";
$ grep login controllers/Admin/Admin.php
    public function login()

How can I troubleshoot these 404 errors in order to properly load the routes in the sub folder?

Hi Team,

If I apply any rule to CI4 Validation that returns string instead of boolean, that rule is skipped. No effect on data output / formatting.

Like this.

PHP Code:

$validation->setRules([
    'username' => 'trim|required',
    'password' => 'required|min_length[10]'
]); 


PHP Code:

$request->getPostGet('username'); // Username is not trimmed. 


This used to be working fine in CI3. How can I attain the same in CI4?

I was thinking of perhaps some kind of simple CMS for small businesses to make a website with pages like homepage, map, menu prices, contact etc... but perhaps this is a bit complex just to showcase the framework. Another idea would be a simple forum, but perhaps someone would have a better idea for a simple project.
I've had a course module and then practical training experience working with the Microsoft's ASP.NET MVC with C#. That was ok, but I'm a Linux guy and have coded (badly) with php as a hobby for some years. I would much rather further my knowledge of php and MVC design architecture which I really liked using with ASP.NET. My front end skills are also up to scratch.

Hi guys ,

I'm lost at this so I want an opinion if it's doable  :

I was asked to see if I can create an online version of a report we now do in excel. The report is quite big
around 50 pages  more or less . It has 10 Main Parts , each part may have up to 20  Sub Parts and
each subpart  contains questions the user fills in by selecting check boxes , one is yes no
and one is 3 different choices (H. M L as High,Medium, Low) and two additional check-boxes.
I'm thinking that the best was to have a single page with all the Main Parts in place and have
a (button ?) to open each additional Sub Part and it's relevant questions with a save/add function.
The thing is I haven't seen any real life example on how (or if it is possible) to do such a workflow
with codeigniter. I have seen similar work with two tables with Datatables plugin  and ajax with php
for example but nothing that uses plain codigniter framework, most examples use a simple view for data.
So the question is this  something  beyond the capabilities of codeigniter and I should turn into
something else to accomplish it or this is something I could do with the framework as is?

Thanks.
