Second join Codeigniter - codeigniter

My function in model looks like:
public function join($table, $select, $join, $on, $join2 = FALSE, $on2 = FALSE, $where = FALSE, $single = FALSE, $order = FALSE, $sort = FALSE, $limit = FALSE)
{
$this->db->select($select);
$this->db->from($table);
$this->db->join($join, $on);
if($join2 == TRUE)
{
$this->db->join($join2, $on2);
}
if($where == TRUE)
{
$this->db->where($where);
}
if($order == TRUE)
{
$this->db->order_by($order, $sort);
}
if($limit == TRUE)
{
$this->db->limit($limit, 0);
}
if($single == TRUE)
{
return $query->row();
}
$query = $this->db->get();
return $query->result();
}
My controller:
public function index()
{
$data['users'] = $this->users_m->get('users');
$join = "blog_list";
$on = "blog_list.id_p = users.id";
$join2 = "meeting_list";
$on2 = "meeting_list.id_p = users.id";
$data['join'] = $this->users_m->join('users', 'users.id, users.nickname, blog_list.cat2, meeting_list.id_m', $join, $on, $join2, $on2, FALSE, FALSE, 'nickname', 'desc');
$this->load->view('admin/users/index', $data);
}
And view:
<?php foreach($join as $row): ?>
<?php echo ($row->id); ?>
<?php echo ($row->nickname); ?>
<?php echo ($row->cat2); ?>
<?php echo ($row->id_m); ?>
<br>
And problem is with second join (when i use $join2), it means when i echo $row->id the id comes from table in $join2 instead from $table. When i use onle one join everything works when i specify in $select that id is from 'user'(users.id) but with second join it wont works. Any idea?

Try editting your select in this way that you select fields by name and then assign them to another name. So, par example:
public function index()
{
//Other code
$data['join'] = $this->users_m->join('users', 'users.id as uid, users.nickname, blog_list.cat2, meeting_list.id_m', $join, $on, $join2, $on2, FALSE, FALSE, 'nickname', 'desc');
//Other code
}
Now echo :
<?php echo ($row->uid); ?>

}
}
}
}
in this script i just didnt know where i can take this alerts and what a parameter can i use to add this alerts . like if num_rows = 1 , echo = blablabla
thanks you sir
you have to use flash data in code igniter or you can use ajax callback in success you can alert what you want and redirect to whatever you like.
Controller
$this->session->set_flashdata('error_message', 'Incorrect Username or Password ! Please try again.');
redirect(URL.'backend/login');
View
<?php
if ($this->session->flashdata('error_message'))
{
?>
<div class="alert alert-danger" style="color: #fff;">
<!-- <button class="close" data-close="alert"></button> -->
<span><?php echo $this->session->flashdata('error_message'); ?></span>
</div>
<?php
}
if ($this->session->flashdata('ok_message'))
{
?>
<div class="alert alert-success">
<!-- <button class="close" data-close="alert"></button> -->
<span><?php echo $this->session->flashdata('ok_message'); ?></span>
</div>
<?php
}
?>
try this.i hope it will help you.
else{
echo '<script language="javascript">';
echo 'alert("Record Updated Successfully")';
window.location.href = 'web';
echo '</script>';
}

Object of class error in Codeigniter with loading function in array

On my Welcome controller I have a function called content_top which loads function $this->$part[0]($setting_info); in this case $this->slideshow($setting_info); Then it should display that slideshow functions view in that data array.
When I have refreshed my page I get a error
A PHP Error was encountered

Question Is there any way to when I have a function in array to be able to make it display the view with out throwing error.
<?php
class Welcome extends CI_Controller {
public $data = array();
public function __construct() {
parent::__construct();
$this->load->model('design/model_layout');
$this->load->model('extension/model_module');
$this->load->model('design/model_banner');
$this->load->model('tool/model_image');
$this->load->library('image_lib');
}
public function index() {
$this->load->view('common/header');
$data['content_top'] = $this->content_top();
$this->load->view('common/welcome_message', $data);
$this->load->view('common/footer');
}
public function content_top() {
if ($this->uri->segment(1)) {
$route = $this->uri->segment(1) .'/'. $this->uri->segment(2);
} else {
$route = 'common/home';
}
$layout_id = $this->model_layout->get_layout($route);
$data['modules'] = array();
$modules = $this->model_layout->get_layout_modules($layout_id, 'content_top');
foreach ($modules as $module) {
$part = explode('.', $module['code']);
if (isset($part[1])) {
$setting_info = $this->model_module->get_module($part[1]);
if ($setting_info) {
$data['modules'][] = $this->$part[0]($setting_info);
}
}
}
return $this->load->view('common/content_top', $data);
}
public function slideshow($setting_info) {
static $module = 0;
$data['banners'] = array();
$results = $this->model_banner->get_banner($setting_info['banner_id']);
foreach ($results as $result) {
$data['banners'][] = array(
'banner_image' => $this->model_image->resize($result['banner_image'], $setting_info['width'], $setting_info['height'])
);
}
$data['module'] = $module++;
$data['resize_errors'] = $this->image_lib->display_errors();
return $this->load->view('module/slideshow', $data);
}
}
In the CI when you loading the view and printing as a string then need to pass the third parameter as 'TRUE'.
<?php echo $this->load->view('headers/menu', '', TRUE);?>
Solved
On the controller I had to change a couple things around
I also have had to use a template layout to minimize the views
But on content_top and sideshow function I had to use return and true
return $this->load->view('folder/name', $this->data, TRUE);
Controller
<?php

Proof Working
This happened to me when I did this:
$model = $this->load->model('user_model);
$data = [
'model' => $model
];
instead of this:
$this->load->model('user_model);
$model = $this->user_model->edit();
$data = [
'model' => $model
];
then when I echoed out the $model, it gave me the error. So I tried to print_r then it gave me a very long array until I realize my mistake. Hope it helps.
Just remove the echo on view page when you are using CI new versions.
<?php $this->load->view('headers/menu');?>

Codeigniter dropdown only retrieve last data from db

I use CI form with form_dropdown helper and tried to pull Mysql data into its options, from the below code, its only retrieve the last record from db into the option list?
please advise what is wrong with my code?
Model
public function getStates() {
$query = $this->db->get('states');
$return = array();
if($query->num_rows() > 0){
$return[''] = 'please select';
foreach($query->result_array() as $row){
$return[$row['state_id']] = $row['state_name'];
}
}
return $return;
}
Controller
$this->load->model('db_model');
$data['options'] = $this->db_model->getStates();
$this->load->view('create_new', $data);
View
$state = array(
'name' => 'state',
'id' => 'state',
//'value' => set_value('state', $state)
);
<?php echo form_label('State', $state['id']); ?>
<?php echo form_dropdown($state['name'], $options); ?>
<?php echo form_error($state['name']); ?>
<?php echo isset($errors[$state['name']])?$errors[$state['name']]:''; ?>
send full query result from the model to the view like this
Model
public function getStates() {
$query = $this->db->get('states');
return $query->result();
}
let the controller as it is and now you can populate states in dropdown like this:
View
<?php
foreach($options as $opt){
$options[$opt->state_id]=$opt->state_name;
}
echo form_dropdown($state['name'], $options);
?>
Try this:
function getStates() {
$return = array();
$query = $this->db->get('states')->result_array();
if( is_array( $query ) && count( $query ) > 0 ){
$return[''] = 'please select';
foreach($query as $row){
$return[$row['state_id']] = $row['state_name'];
}
}
return $return;
}

Codeigniter. Controller cannot receive session data

I set session successfully as output profiler show me session name and value.
But when I POST data controller cannot receive session data.
Library is loaded, $config['sess_expire_on_close'] = TRUE I've changed TRUE-FALSE without any success. Also tried rewrite code.
And another question I use two PC and on Linux machine I get error "Header already sent...", but on Win machine I don't receive this message. How to enable it on Win PC. Notices and warnings are enabled.
So ...
Controller kmgld:
function authorisation_user()
{
......
$data['set_cookie'] = "Surname";
......
$this->load->view('vheader', $data);
$this->load->view('vuser_kmgld');
$this->output->enable_profiler(TRUE); //show me only session name and value which I set
}
View:
if ($set_cookie!=NULL)
{
$this->session->set_userdata('surname',$set_cookie);
}
<!Doctype...>
<form action="<?php echo base_url()?>index.php/kmgld/update_kmgld" method="post" name="">
And again Controller kmgld
function update_kmgld()
{
...update DB
$test=$this->session->userdata('surname');
echo $test; //it is NULL
$this->output->enable_profiler(TRUE); // show me only now session id, ip, user agent
}
you have to set the userdata in the controller, the view isn't the proper place for it. so you probably would do something like this in your controller:
$surname = "Surname";
$this->session->set_userdata('surname',$surname);
$data['set_cookie'] = $surname;
...
$this->load->view('vheader', $data);
don't know if you autoload the session library. otherwise you have to load it in every function you need it.
remove session setting from view and do it in controller:
function authorisation_user()
{
$data['set_cookie'] = "Surname";
$this->session->set_userdata('surname',$set_cookie);
$this->load->view('vheader', $data);//are you sure here is where $data should go ?
$this->load->view('vuser_kmgld');//not $data here?
$this->output->enable_profiler(TRUE); //show me only session name and value which I set
