set_cookie() doesn't work with redirect()

≪ Previous: Upgrade CI2x to CI3 (USA ONLY)

Hello,
This is my code:

PHP Code:

namespace App\Controllers;
use CodeIgniter\Controller;

class Home extends Controller
{
    public function __construct()
  {
    helper(['cookie']);
  }
    public function page1()
    {
        set_cookie('test', 'testvalue-'.time(), time() + 86400);
        return redirect()->to('page2');
    }
    public function page2()
    {
        echo get_cookie('test');
    }
} 

Redirect is working but there is no 'test' cookie on page2. Please help.

≪ Previous: set_cookie() doesn't work with redirect()

Hi,
I have created a BaseController extending CI Controller :

Code:

<?php namespace App\Controllers;

class BaseController extends \CodeIgniter\Controller

{

    protected $env_data;

    protected $env_user;

    function __construct()

    {

        $this::init();

    }

    function init() {

        $this->env_data = ['init'=>'yes'];

        $this->env_user = [];

        if(empty($this->env_user)) {

            return redirect()->to('/login');

        }

    }

}

I then created controller Home2 :

Code:

<?php namespace App\Controllers;

class Home2 extends BaseController

{

    public function __construct()

    {

        parent::init();

    }

    public function index()

    {

        print_r($this->env_data);

        //return redirect()->to('/login');

        return view('welcome_message', $this->env_data);

    }

}

Calling Home2 displays array $this->env_data containing "init"=>'yes'. The redirection does not work.

Can someone confirm this is the expected result?

Why is redirection not working in BaseController?

Thanks in advance!

Session/Redis question

December 6, 2018, 2:34 pm

≫ Next: use try catch in index.php file

≪ Previous: Redirect

If I'm using redis for sessions and I store some session data in variables for 'user' (active user data) and 'business' (active business) and then I get those session variables with:

$session->get('user');
$session->get('business');

Is that making two calls for the redis server?

Am I better off doing:

$data = $session->get();

$data['user'];
$data['business'];

Is that one call?

I'm running my application on the Google Cloud. I'm obviously trying to reduce calls to the redis server and can't see those calls like database calls in the debug bar. That would be sweet if I could... but not necessary if I knew what is happening.

Bonus question, the session docs mention data will be stored in $_SESSION superglobal. Is that true for redis?

Thanks in advance!

{0} is not a valid rule.

For additional question, can someone give simpler example how to send parameters to the function? I don't get the 'require_with' example.

Pagination links

≫ Next: Where to create model, view, controller folders for my projects

≪ Previous: Custom Validation doesn't work?

I'm having a little trouble with pagination links, I'm building a jobsite and on the front end when viewing jobs the pagination works fine with no problem.

In admin I have a similar method that lists jobseekers, it is here that I'm having the trouble, the pagination links appear on this page and when I click the links the results appear to be changing correctly, i.e the next set of 12, but the actual pagination link doesn't change.

the url ends with, /admin/jobseekers

when I click the first pagination link the url goes to /admin/jobseekers/12

Then I click the next pagination link and I get /admin/jobseekers/24 and so on as it increments by 12 each time, the results are also correctly serving each set of 12.

So I have discovered that the pagination itself is working but the problem is with the actual pagination links:

So when the page loads the pagination links are like:

<ul class="pagination">
<li class="page-item"></li><li class="page-item active"><span class="page-link">1</span></li>
<li class="page-item"><a href="http://codeigniter.local/admin/jobseekers/12" class="page-link" data-ci-pagination-page="2">2</a></li>

etc etc

Now the error happens when I click '2'

The link structure isn't changing, number one should become a hyperlink and number two should be just a span, but for some reason it does not change, it's like the links are stuck in the same format with number one being a span and all the others after it are links.

I've been trying to figure this out for days and just cannot get to the bottom of it, I'm sure this must be something simple that I am overlooking but I just cannot pin point where the cause is.

Like I said I have a job list method that works fine and I have tried to mirror the code but still the links will not change, could anybody please advise? Does somebody with more experience recognise this issue and might know what it is?

Creating widgets containing links to pages

December 7, 2018, 5:34 am

≫ Next: form_open adds index.php to path

≪ Previous: PHP 7.3.0 Released

I've made an open-source blogging application and I need some help with it. The application supports not only posts, but pages too.

I also uploaded an instance of the application, with dummy content, on my server. Click on HERE to see it.

The concrete problem: in the footer of the site I display some pages (not posts). The way I display them is unsatisfactory for me, because it implicates hardcodeing:

Code:

<div class="col-sm-6 col-md-3">

      <h3>Legal</h3>

       <ul class="list-unstyled">

       <?php foreach ($pages as $page): ?>

        <li><a href="<?php echo base_url('pages/page/') . $page->id; ?>"><?php echo $page->title; ?></a></li>

       <?php endforeach; ?>

      </ul>

   </div>

This allows me to display the pages in only one "box". Maybe I would find a solution that lacks... elegance (it would involve some if statements) to display two pages in each box.

Perhaps widgets (like WordPress has) would be a good idea. Widgets in which I could drag-and-drop (links to) pages and other entities. I have not found any tutorials on making widgets in Codeigniter.

I don't now if CI has helpers or any other features to support widget creation. I am a beginner (intermediate at best) PHP developer so I don't know where to start creating this feature. Please help. Come with the best approaches.

form_open adds index.php to path

≪ Previous: Creating widgets containing links to pages

Hi,
Using form_open('your/path') adds the index.php to the absolute path in the final HTML while using base_url('your/path') does not.
Posting form data is not working when I use .htaccess to remove index.php from the path AND index.php is part of the absolute path.
I suggest removing index.php from all CI generated path in the future so all functions will output a path like base_url for consistency.

If you have the same problem as I had not being able to post form data using form_open() you can use the following code instead:
<form action="<?= base_url('your/path')?>" method="post" accept-charset="utf-8">

I use the following code in .htaccess to remove index.php and redirect:

#1) redirect the client from "/index.php/foo/bar" to "/foo/bar"
RewriteCond %{THE_REQUEST} /index\.php/(.+)\sHTTP [NC]
RewriteRule ^ /%1 [NE,L,R]
#2)internally map "/foo/bar" to "/index.php/foo/bar"
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [L]

If in Controller I do this:

Code:

$this->load->model('mymodel');

//...do some stuff with mymodel...

//calling the view

$vars['somedata'] = 'mydata';

$this->load->view('someview', $vars);

Inside the View someview.php you can do this

Code:

$this->mymodel->someMethod();

Isn't this a security threat? Huh

The View should only be able:

to see the data passed by the Controller
and to load others Views

but the View should NOT be allowed to call directly methods of any model.

Alpha.4 coming Dec 15th

December 8, 2018, 11:10 pm

≫ Next: is this migration bug?

≪ Previous: Once the model is loaded by the controller all model methods are exposed to view

We are providing a heads up for the next alpha release, planned for Sat Dec 15th.

It will contain a minor backwards compatibility break, in order to align the path constants and folder names used in CodeIgniter 4:

- The *application* folder gets renamed *app* (matching *APPPATH*)
- The *BASEPATH* constant gets renamed *SYSTEMPATH* (matching the *system* folder)
- The remaining folders and constants remain the same
- The source code has been modified to accommodate these

There will be a few changes for you to make when upgrading to this release:
- rename your *application* folder to *app*, if you download the framework or use an app installer
- global replace "application/" with "app/"
- global replace "BASEPATH" with "SYSTEMPATH"
- there may be similar adjustments to other parts of your code, depending on how much you have customized things

Once the dust has settled, paths will be set in a limited number of places:
- spark & system/bootstrap.php; the path constants are set in these, the two intended entry points.
- app/Config/Paths.php - this class defies properties istead of constants, so that you might apply rules to determine their setting.

Our goals are two fold:
- Have stable & consistent path & folder naming, as we move forward
- Make it easier to handle developer preferences, if they want a different folder structure

The pull request that makes this happen is #1579, in case you wish to test the change yourself.
Please let us know your thoughts & concerns.

CodeIgniter 4 installation shall not require composer

≫ Next: Codeigniter framework not loading the page

≪ Previous: Cart Class Issue

IMHO one of the main thing that makes CodeIgniter attractive to the developer that approaches for the first time an MVC framework, and what makes it different from big frameworks (like Sinfony and Laravel) is the CodeIgniter extremely simple installation process that do not require to install, learn and use another tool like Composer.

I don't know if you still remember when you installed CodeIgniter for the first time, I was in hurry and I didn't have time to waste playing with another tool (Composer), hence I decided to give CodeIgniter 3 a try because it was the only framework comparable (by widespread user base, and online support/tutorials, etc.) to Laravel/Symfony, but CodeIgniter did not require me to waste time learning another tool.

Hence, I think CodeIgniter 4 installation shall not require Composer to be used at all.

What do you think about this?
