I want to retrive count of datas from one table and some datas from another table , also i want to know how to display these in a single foreach loop.
Model
public function counter(){
$this->db->where('package_id', $id);
$this->db->from('gt_package');
$cnt = $this->db->count_all_results();
}
Controller
public function package_category_listing()
{
$data['records'] = $this->gt_package_model->counter();
$query = $this->db->get("gt_package_category");
$data['records'] = $query->result();
$this->load->view('admin/package/package_category_listing',$data );
}
View part :
<?php foreach ($records as $r) { ?>
<div class="col-sm-6 col-md-3 col-xs-12">
<div class="bg-purple">
<h4 class="text-white">
<?php echo $r->category_name; ?>

As per your question to pass the data model to controller code bellow
Model:
public function counter()
{
$this->db->where('package_id', $id);
$this->db->from('gt_package');
$query = $this->db->get('gt_package');
$cnt = $query->num_rows();
return $cnt;
}
Controller:
public function package_category_listing()
{
$data['records'] = $this->gt_package_model->counter();
$query = $this->db->get("gt_package_category");
$data['records'] = $query->result();
$this->load->view('admin/package/package_category_listing',$data );
if($res){
$data['result'] = $res;
$this->load->view('manage_accounts_view', $data);
} else {
echo "Fail";
}
print_r($data['result']);
}
I am having a blog page where the blogs are inserted from admin panel and blog title will be inserted into new column as separated by " - " if there are spaces between the page titles.For example if the page title is " welcome to something " then in the database it is will be inserted into two columns. In once column it will be inserted as same and in other column it will be inserted as welcome-to-something.
when clicking on readmore button i need to display in url as (www.example.com/blob/article/welcome-to-something) in this format i need to display the url.

$data['mainpage'] = "blog";
$this->load->view('templates/template',$data);
}
public function article()
{
$this->load->model('blogs_model');
$data['records2']= $this->blogs_model->getblogsdata($this->uri->segment(3));
$data['mainpage']='blogs';
$this->load->view('templates/templatess',$data);

Can someone please tell me why I am getting the error.
It will be like this
$data['query'] = $api->get_todo();
$this->load->view('dashboard/inc/header_main_view', $data);
You did not passed variable to view right way.$query is not available at your view.CI converts array or object keys as variable which is sent from controller.See Adding Dynamic Data to the View From the doc.
You need to fix your controller like this
$data['query'] = $api->get_todo();
$this->load->view('dashboard/inc/header_main_view', $data);
//your view will get all key of $data as variable.
//your view will get $query from above code
i've been debbuging it many times based on my knowledge, i am new to codeigniter, any solution idea would be much appreciated... ty
here's my code
MODEL:
function userdisplay_info($id){
$result = $this->db->query("SELECT uid FROM user WHERE userIdentificationNumber LIKE '$id'");
//if($result->num_rows() > 0){
$info_data = $result->result();
$row = $info_data[0];
$result->free_result();
}

function r_book(){
$data = array();

Rewrite your model function as
function userdisplay_info($id){
$this->db->select('uid');
$this->db->like('userIdentificationNumber', $id);
$query = $this->db->get('user');
return $query->result_array();
}
I want to edit some data after a POST in CodeIgniter.
The problem is when I make an edit I want to show a message that tells me the edit is done. I tried to do the following, but no message is displayed. Why?
Controller
function edit($id = 0) {
$this->load->model('Event_Model');
if ($id > 0) {
$this->data['eventinfo'] = $this->Event_Model->getInfo($id);
}
$this->data['pagetitle'] = "Edit";
$this->data['formID'] = $this->uri->segment(2)."-".$this->uri->segment(3);
$this->template->build('admin/events/add',$this->data);
}
function do_edit() {
$this->load->model('Event_Model');
$id = $this->input->post('hID');
$data = array(
'ev_text' => $this->input->post('ev_text'),
'ev_pic' => $this->input->post('ev_pic'),
);
$this->Event_Model->update($id, $data);
$this->data['success'] = "Done";
$this->data['errors'] = $this->errors;
$this->template->build('admin/events/add',$this->data);
}
Model
function update($id, $data) {
$this->db->where('ev_id', $id);
$this->db->update('events', $data);
}
View (where I want the message)
<?php
if (isset($success)) { ?>
<div class="alert alert-success normal-alert" style="display: block;">
<p><span class="ico-text ico-alert-success" ></span><?= $success; ?></p>
</div>
<?php
}
if (isset($errors)) { ?>
<div class="alert alert-error normal-alert" style="display: block;">
<div>
<span class="ico-text ico-alert-error"></span>
<?php if (count($errors) > 0) { ?>
<ul>
<?php
foreach ($errors as $error) {
echo "<li>$error</li>";
}
?>
</ul>
<?php } ?>
<div class="clear"></div>
</div>
</div>
<?php } ?>
and the second error, update data with picture not work, its get me error in dubg that call me the $_FILES['choose-file']['name'] not define
Try This:
Controller
function do_edit() {
$this->load->model('Event_Model');
$id = $this->input->post('hID');
$data = array(
'ev_text' => $this->input->post('ev_text'),
'ev_pic' => $this->input->post('ev_pic'),
);
$result = $this->Event_Model->update($id, $data);
if($result) {
$this->data['success'] = "Done";
$this->template->build('admin/events/add',$this->data);
}
$this->data['errors'] = $this->errors;
$this->template->build('admin/events/add',$this->data);
}
Model:
function update($id, $data) {
$this->db->where('ev_id', $id);
$this->db->update('events', $data);
return $this->db->affected_rows();
}
