I want to compress the image by 60%. My code is given bellow. I have uploaded an image of 627Kb. The code block is executed but not compressing. Is there any error in my code?

Thanks in advance.

PHP Code:

$this->load->library('image_lib');
if($this->upload->data('file_size') > 300){
    $config['image_library']    = 'gd2';
    $config['source_image']     = $this->upload->data('full_path');

Hello, i'm trying to make a simple test using 'HTTP Feature testing' as described in Documentation. But, after hours of trying I couldn't achieve it.

This is my implementation class:

PHP Code:

<?php

namespace App\Controllers;

//use App\Libraries\Traits\ExtendedController;
use CodeIgniter\Controller;

class Home extends Controller
{
   // use ExtendedController;

        return view('welcome_message');
    }

}

PHP Code:

<?php
namespace Tests;

use CodeIgniter\Test\FeatureTestCase;

class TestHome extends FeatureTestCase
{

    public function setUp()
    {
        parent::setUp();

Rewriting query in query builder

≪ Previous: In Dropdown href not taking method in controller

Hi there,

I'm pretty new to Codeigniter. I have trouble with Mysql query converting to CI query builder.

So, original query is this:

PHP Code:

$query = $this->db->query('SELECT' .
' p_pedestal.*,' .
' dev.dev_name AS device,' .
' p_port.title AS port,' .
' UNIX_TIMESTAMP(p_pedestal.created) AS created_t,' .
' UNIX_TIMESTAMP(p_pedestal.updated) AS updated_t' .
' FROM p_pedestal' .
' LEFT JOIN p_port' .
' ON p_pedestal.port_id = p_port.id' .
($this->system->isOwner()?
' JOIN p_port_user_rel ON (p_port_user_rel.username = "' .
strtolower($_SESSION['user']['username']) .
'") AND p_port_user_rel.port_id = p_pedestal.port_id' : ''
) .
' INNER JOIN dev' .
' ON p_pedestal.dev_id = dev.dev_id' .
' ORDER BY p_pedestal.formatted_address ASC '
); 

It works fine, all is good.

Now, I tried rewriting it and it just never works, I have no idea why.
This is what I got so far:

PHP Code:

$query = $this->db
->select('p_pedestal.*,
dev.dev_name AS device,
p_port.title AS port,
UNIX_TIMESTAMP(p_pedestal.created) AS created_t,
UNIX_TIMESTAMP(p_pedestal.updated) AS updated_t'
)
->from('p_pedestal')
->join('p_port', 'p_pedestal.port_id = p_port.id', 'left')
->join('p_port_user_rel', 'p_port_user_rel.username =' . strtolower($_SESSION['user']['username']) )
->where('p_port_user_rel.port_id', 'p_pedestal.port_id')
->join('dev', 'p_pedestal.dev_id = dev.dev_id', 'inner')
->order_by('p_pedestal.formatted_address')
->get(); 

And second part of my question is- how would you go about $this->system->isOwner()?
Would you put it in if statement, run one query or run another one with additional Join?

Thanks in advance Smile

Hi,
I am building a website using CI for a customer.

2. Users can create blog posts
3. Users can create announcements
4. Users can create categories

≪ Previous: CMS Admin Dashboard Example

I am trying to install CI on a new Linux laptop. I modified index.php to point at the CI directory at /Home/codeigniter/CodeIgniter-3.1.10/system, but when I type localhost in the browser I am getting

"Your system folder path does not appear to be set correctly. Please open the following file and correct this: index.php"

I modified index.php to be:

*---------------------------------------------------------------
* SYSTEM DIRECTORY NAME
*---------------------------------------------------------------
*
* This variable must contain the name of your "system" directory.
* Set the path if it is not in the same directory as this file.
*/
$system_path = '/Home/codeigniter/CodeIgniter-3.1.10/system';

/*

what is wrong? Do I need to also update the application_folder path?

The way I moved over from the Windows PC is that I copied my application directory which is c:/xampp/htdocs/sub_crud. It contains application, system, etc. Does this mean that I didn't need to do a reinstall of CI? Could I have just pointed $system_path at /var/www/html/sub_crud/system on the Linux PC?

Session Issues

≫ Next: For Cpanel, it works perfectly, however, it fail in plesk server.

≪ Previous: set sql variable before main query

So I'm having a strange issue with sessions on one of my websites. Before getting into too much detail, I have two websites using the same CI version (3.1.10) configured exactly the same and both are also using PHP 7.2. Sessions are working perfectly fine on one, but not on the other. Upon using the browser debug tools, I see that on the site that is not working, the session is showing the full array instead of the session ID. The extent of the differences between both websites are the HTML, CSS, Domain, and DB credentials (shared VPS, same PHP INI, same DB version). Both domains use SSL.

Here is my session configuration in config.php:

$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

In browser debug under storage (firefox) working website shows:

ci_session: "f89h3983hf89h389fh3" (ID isn't real, just wanted to show you what I see).

And website that has the issue shows:

ci_session: array 0 : "blah" 1 : "blah: 2 : "blah" (all the way up to...) 22 : "blah"

Funny part is that if I swap the DB configuration from the non-working site over to the working site and post information, it works without issue, which is what I've been doing to circumvent the issue in the interim.

I turned on logging and there were no errors. Figured I'd just suck it up and ask for help because at this point I'm just spinning my wheels. Let me know if there is anything else I can provide that might shed some light on the issue.

I have gone through the ArrayHelper file and found only one function.

There are multiple functions which we use in our development, which we wish to have in core helpers

Can we suggest those as well to be a part of core functionality instead of custom?

This might help all developers to get the one-stop solution

Suggested functions can be,

array_sort_by_column
array_remove_empty_elements
array_search_by_key
array_search_by_value
array_change_key_case_recursive

Hello to all of you as premise I say I'm very basic with Codeigniter

this is Ci 3.1.10

I suspect my issue is matter of a wrong configuration in some file Confused

This Codeigniter pagination with ajax is running localhost on xampp

Here it is the code of this really simple experiment,

mean a short tutorial
just matter of db creation
one controller using the codeigniter pagination library
and one view with jquery ajax at bottom

Well

the codeigniter folder has been renamed ci-pag
it is in

Code:

http://localhost/ci-pag

and pointing to there I have the standard welcome controller with CI welcome message

I have created the test db as in the tutorial using the provided query and filled in some data

briefly copied and pasted the provided controller and view with obviously the same names

configured codeigniter as ususal (for my xampp experiments) mean
- created .htaccess
- added the rewrite stuff for index.php removal
- changed the config.php to remove the index.php and set the base path to http://localhost/ci-pag/

THE ISSUE
when I point to

Code:

http://localhost/ci-pag/post

it does show only the header of the page but for the rest nothing Sad

you can see the screenshot here No table just header

Hi, I've just upgraded Ion Auth for my app, but am unable to create a new user anymore with the register function without a password.

In my original implementation, admin create the users, and users receive an email activation link upon being created. Clicking the link sends the user to a set password page, where upon completion ion_auth->activate is called.

Is there some way around this? I mean I could create a long random string for the password argument, but it seems a bit hacky.

How to manage large database without stalling or slowing the application?

≪ Previous: bug for multi insert for single mysql query

Hi,

I need some advice or help on how I can manage/optimize my large recordset in our database without stalling or making the application slow.

Currently, our database has over 100,000+ records and I have a query that simply fetch unique values for my filter (for export report):

PHP Code:

protected $options = array();

public function fetch_filter_options()
{
    if (empty($this->options))
    {
        $res = $this->db
                ->select('t.*')
                ->select('NULLIF(CONCAT(`u`.`firstname`, " ", `u`.`lastname`), "") AS `initiator_name`')
                ->from('casetracker as t')
                ->join('users as u', 'u.uid = t.initiator', 'left outer')
                ->get()
                ->result();

        // Initialize
        $options = [
            'weeknumber'        => [],
            'teamleader'        => [],
            'solver'        => [],
            'initiator_name'    => [],
            'numtimesedited'    => []
        ];

        foreach ($que as $res)
        {
            foreach ($options as $key => $array)
            {
                if ( ! array_key_exists($res->{$key}, array_keys($options[$key])))
                {
                    $options[$key][$res->{$key}] = $res->{$key};
                }
            }
        }

        $this->options = $options;
    }
    
    return $this->options;
} 

(I alter the code because it contains sensitive information, sorry)

When I tried to fetch 100,000+ rows, I get the "Fatal error: Allowed memory size".
Some suggest to use unbuffered queries. But I use Query Builder. I don't know how to do that.
Or maybe I should re-structure my code?

Thank you.
