Hello,

I have a question about codeigniter 3.x --> I am reading the description there are calender( ) and tablesorter( ).

I wonder why there are no manuals on how to use the function ?

http://www.codeigniter.com/user_guide/li....html#id22

Is it still under construction ?

When will it be launch ? Am I able to request new features if I need it ?

Has codeigniter 3.x be stable ? What version is underconstruction ? 3.x or 4.0 ?

Thanks in advance.

You are not reading the description carefully enough.
At the top of the Javascript library writeup that you mention, there is a prominent notice:

Important
This library is DEPRECATED and should not be used. It has always been with an ‘experimental’ status and is now no longer supported. Currently only kept for backwards compatibility.

The library will be removed in an upcoming version of CodeIgniter.

CodeIgniter 3.x *is* stable, currently up to version 3.0.6.
CodeIgniter 4.x is under development.

What about the calendering class: ?

http://www.codeigniter.com/user_guide/li...light=date

I try this:

views/blog_form.php

PHP Code:
<html>

<title>Blog Form</title>

<br>

<h1>BLOG FORM</h1>

<?php $this->load->helper('form'); ?> 
<?php $this->load->library('calendar');  ?>

<?php echo validation_errors(); ?>

<?php echo form_open('form'); ?>

<table>

<tr>
<td>Date  :</td>
<td><?php echo $this->calendar->generate();  ?></td>
</tr>

controllers/Blog.php

PHP Code:
<?php

class Blog extends CI_Controller {

        public function index()
        {
            
                $this->load->helper('form'); 
            
                //$this->load->helper(array('form', 'url'));
                $this->load->library('form_validation');

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

                $data['title'] = $this->blog_model->select_blog();
                $data['content'] = $this->blog_model->select_blog();
                $data['date'] = $this->blog_model->select_blog();
                
                $this->load->view('blog', $data);
                                            
                //$this->load->view('blog');
        
        }
        
        public function blog_form()
        {
                $this->load->view('blog_form');
                                
        }
}

?>

Yes? That is part of CI 3.x, and it is not deprecated.
Is that what you are wondering?

Ok thanks. Just one problem. I get this list of errors:

Try moving these into your controller:

PHP Code:
<?php $this->load->helper('form'); ?> 
<?php $this->load->library('calendar');  ?>

Calling the loader from your view is likely to cause some issues in many circumstances, so it's best to avoid doing so. The documentation of the calendar library specifically states (emphasis mine):

Quote:Like most other classes in CodeIgniter, the Calendar class is initialized in your controller using the $this->load->library function

views/blog.php

PHP Code:

<?php $this->load->helper('date'); ?>

<?php $blogs = $this->blog_model->select_blog();  ?>

<?php foreach ($blogs as $row) : ?>

    <b><?php echo $row->title; ?></b><br><br>
    <?php echo $row->content; ?><br><br><br>
    
<?php endforeach; ?>

</html>

I already place those 2 helper in controllers:

PHP Code:
<?php $this->load->helper('form'); ?> 
 <?php $this->load->library('calendar');  ?>

and still have the above error message.

They're not in the right place in your controller (the index() method is not called when displaying the view you're getting the error message on), and you need to remove the surrounding PHP tags from the method calls when you put them in the controller (since the opening PHP tag is at the top of the controller).

You have a lot of questions posted in the forum regarding the same form. You can't solve the issues independently, and changes you make in solving one issue can make other issues appear or disappear. It's also fairly obvious that you need to go through the overview and tutorial sections in the manual (or go back through it, if you have already).
