Apa yang harus dilakukan saat upload web aplikasi pada Server dengan menggunakan CodeIgniter (CI)

Dalam membuat sebuah sistem informasi dibutuhkan skill dan logika yang mumpuni. Setidaknya memahami dalam setiap masalah yang ada seperti dalam aplikasi berbasis web dengan CodeIgniter. Pernahkah anda memiliki hasil tampilan seperti ini:

A PHP Error was encountered

Severity: Warning

Lalu bagaimana cara mengatasi masalah ini,

Bagaimana cara untuk membedakan CodeIgneter atau CI di locahost dan server atau hosting,

Jika ada masalah seperi di atas, maka lakukan perubahan Config pada Folder Application/config/config.php.
Jika menggunakan localhost, maka cari dan gunakan kode berikut:

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

Jika menggunakan server atau hosting, maka cari dan gunakan kode berikut:

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

Masih banyak masalah lainnya. Seperti

A PHP Error was encountered

A PHP Error was encountered

Backtrace:

Pemecahan masalahnya adalah sebagai berikut:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller
{
 function __construct()
 {
     parent::__construct();
     setlocale(LC_TIME, "");
.................................................
         ini_set('max_execution_time', 0); 
         ini_set('memory_limit','2048M');
 }

Kode ini ditambahkan pada Controller yang ingin diberikan tambahan waktu upload file
         ini_set('max_execution_time', 0);
        ini_set('memory_limit','2048M');


Kesalahan lain:


Warning: Declaration of ActiveRecord\DateTime::setTime($hour, $minute, $second = NULL) should be compatible with DateTime::setTime($hour, $minute, $second = NULL, $microseconds = NULL) in F:\xampp7\htdocs\project\vendor\php-activerecord\php-activerecord\lib\DateTime.php on line 139

Pemecahan masalah:
ganti file dengan https://github.com/jpfuentes2/php-activerecord/blob/master/lib/DateTime.php
hilangkan  implements DateTimeInterface pada baris 36 yaitu:
class DateTime extends \DateTime

set_userdata codeigniter not working

Codeigniter $this->session->set_userdata() not working

In CodeIgniter 3.x if you just upgraded to PHP version 7.x, go to system/libraries/Session/session.php at line 281 and replace or give comment for this line "//":

ini_set('session.name', $params['cookie_name']); 

change it with:

ini_set('session.id', $params['cookie_name']);

how to enable error log in codeigniter

/application/config/config.php

$config['log_threshold'] = 1
