I have two functions in my model as
class Jobseeker_model extends CI_Model
{
public function __construct()
{
parent::__construct();
$this->load->database();
}
public function result_getall($id)
{
$this->db->select('*');
$this->db->from('tbl_jobseeker');
$this->db->where('tbl_jobseeker.User_id',$id);
$this->db->join('tbl_work_exp', 'tbl_jobseeker.User_id = tbl_work_exp.User_id','left');
$query = $this->db->get();
return $query->row();
}
public function select($id)
{
$this->db->select('*');
$this->db->from('tbl_qualification');
$this->db->where('tbl_qualification.User_id',$id);
$query = $this->db->get();
return $query->result();
}
}
And in my controller I have a function as
public function display()
{
$id = $this->session->userdata('user_id');
$data['row'] = $this->jobseeker_model->result_getall($id);
$res['a'] = $this->jobseeker_model->select($id);
$this->load->view('jobseeker_display.php', $data,$res);
}
It is not possible to display the view page.. I could pass two variables into my view page.right?
You can pass your any number of variables/arrays using a single array.
In Controller:
public function display() {
$id = $this->session->userdata('user_id');
$data['var1'] = $this->jobseeker_model->result_getall($id);
$data['var2'] = $this->jobseeker_model->select($id);
$this->load->view('jobseeker_display.php', $data);
}
In View:
`$var1` and `$var2` will be available.
You can pass your two variable using single srray
public function display()
{
$id = $this->session->userdata('user_id');
$data['row'] = $this->jobseeker_model->result_getall($id);
$data['a'] = $this->jobseeker_model->select($id);
$this->load->view('jobseeker_display.php', $data);
}
Views
foreach($a as $data){
// your code
}
echo $row->column_name;
Try this
public function display()
{
$id = $this->session->userdata('user_id');
$data['row'] = $this->jobseeker_model->result_getall($id);
$data['a'] = $this->jobseeker_model->select($id);
$this->load->view('jobseeker_display.php', $data);
}

I am doing ajax scrolling pagination. Controller is like below
<?php
require APPPATH . '/controllers/user/Usercontroller.php';
class PaginationController extends Usercontroller{
public function __construct(){
parent::__construct();
$this->load->model("Usermodel","",true);
}
private $perPage = 5;
public function index(){
$tutorId=$this->session->userdata('cp_userid');
$categorycourses=$this->Usermodel->getcourses($tutorId);
$count = $categorycourses->num_rows();
$data['details']=$categorycourses;
$this->load->view("user/pagination_view",$data,true);
}
}
?>
$count variable contains 5 data, I want to send 3 for first page and remaining for second page. How to do this.
Try this...
Model:
function getcourses($tutorId, $limit = null) {
$this->db->select('*');
$this->db->from('courses');
$this->db->where("tutorId", $tutorId);
//$this->db->order_by("name", "asc");
if($limit!=''){
$this->db->limit($limit);
}
$query = $this->db->get();
$courses = array();
foreach ($query->result() as $row)
array_push($courses, $row);
return $courses;
}
Controller:
public function index(){
$tutorId = $this->session->userdata('cp_userid');
$limit = 3;
$categorycourses = $this->Usermodel->getcourses($tutorId, $limit);
//$categorycourses=$this->Usermodel->getcourses($tutorId);
$count = $categorycourses->num_rows();
$data['details'] = $categorycourses;
$this->load->view("user/pagination_view", $data, true);
}
I am new to code-igniter, and I am facing unknown issues in updation and deletion of rows in my database. My code for Controller is :
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Nhome extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->Model('N_model');
$data['r'] = $this->N_model->getdata();
$this->load->view('Homeview',$data);
}
public function edit()
{
$id = $this->input->get('id');
$this->load->Model('N_model');
$data['s'] = $this->N_model->editdata();
$this->load->view('Neditview',$data);
}
public function loadEdit()
{
$id = $this->input->get('id');
$this->load->view('Neditview');
}
public function insertdata()
{
$eID = isset($_POST['Id'])?$_POST['Id']:'';
$arr['Name'] = $_POST['Name'];
$arr['Gender'] = $_POST['Gender'];
$arr['Email'] = $_POST['Email'];
$this->load->Model('N_model');
$res = $this->N_model->updatedata($arr , $eID);
if($res){
header('location:'.base_url()."index.php/Nhome/".$this->index());
}
}
public function delete(){
$this->load->Model('N_model');
$id = $this->input->get('Id');
$this->N_model->deletedata($id);
$this->index();
}
}
and my code for model is :
<?php
class N_Model extends CI_Model{
public $Id;
public $Name;
public $Gender;
public $Email;
public function __construct()
{
parent::__construct();
}
public function getdata()
{
$va = $this->db->get('newprac');
$res = $va->result();
return $res;
}
public function editdata($id)
{
$vr = $this->db->where('Id',$id);
return $vr;
}
public function updatedata($data , $id){
$this->db->where('newprac.Id',$id);
$res = $this->db->update('newprac', $data);
return $res;
}
public function deletedata($id)
{
$this->db->where('newprac.id',$id);
$this->db->delete('newprac');
if($this->db->affected_rows()>0)
{
return true;
}
else { return false; }
}
}
Change
$this->db->where('newprac.id',$id)
to
$this->db->where('id',$id);
Simplify your code to:
$this->db->where('id',$id)->update('newprac', $data);
Replace your controller by this code. Becuase I think you passing data as a post method so you should use post when you retrieve data.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Nhome extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->Model('N_model');
$data['r'] = $this->N_model->getdata();
$this->load->view('Homeview',$data);
}
public function edit()
{
$id = $this->input->post('id');
$this->load->Model('N_model');
$data['s'] = $this->N_model->editdata();
$this->load->view('Neditview',$data);
}
public function loadEdit()
{
$id = $this->input->post('id');
$this->load->view('Neditview');
}
public function insertdata()
{
$eID = isset($_POST['Id'])?$_POST['Id']:'';
$arr['Name'] = $_POST['Name'];
$arr['Gender'] = $_POST['Gender'];
$arr['Email'] = $_POST['Email'];
$this->load->Model('N_model');
$res = $this->N_model->updatedata($arr , $eID);
if($res){
header('location:'.base_url()."index.php/Nhome/".$this->index());
}
}
public function delete(){
$this->load->Model('N_model');
$id = $this->input->post('Id');
$this->N_model->deletedata($id);
$this->index();
}
}
Did you try to debug using Chrome debugger. You might get the exact error in debugger. I suggest you to try once let me know the error name.
I'm using Codeigniter with dynamic subdomains, but in each method of my controllers I need to get the account of the dynamic subdomain. I'm looking for a way to get the domain and add to the $data without to it every method like:
<?php
class Dashboard extends CI_Controller {
function index()
{
$subdomain_arr = explode('.', $_SERVER['HTTP_HOST'], 2);
$subdomain_name = $subdomain_arr[0];
$this->db->from('accounts')->where('subdomain', $subdomain_name);
$query = $this->db->get();
$account = $query->row();
$data['account_id'] = $account->id;
$data['account_name'] = $account->name;
$this->load->view('index', $data);
}
function clients()
{
$subdomain_arr = explode('.', $_SERVER['HTTP_HOST'], 2);
$subdomain_name = $subdomain_arr[0];
$this->db->from('accounts')->where('subdomain', $subdomain_name);
$query = $this->db->get();
$account = $query->row();
$data['account_id'] = $account->id;
$data['account_name'] = $account->name;
$this->load->view('clients', $data);
}
}
Do it once within a Class Constructor and then you can access the same variables from all of the other methods.
As per docs:
"Constructors are useful if you need to set some default values, or run a default process when your class is instantiated. Constructors can't return a value, but they can do some default work."
<?php
class Dashboard extends CI_Controller {
public $data = array();
public function __construct()
{
parent::__construct();
$subdomain_arr = explode('.', $_SERVER['HTTP_HOST'], 2);
$subdomain_name = $subdomain_arr[0];
$this->db->from('accounts')->where('subdomain', $subdomain_name);
$query = $this->db->get();
$account = $query->row();
$this->data['account_id'] = $account->id;
$this->data['account_name'] = $account->name;
}
public function index()
{
$data = $this->data; // contains your values from the constructor above
$data['title'] = "My Index"; // also use your $data array as normal
$this->load->view('index', $data);
}
public function clients()
{
$data = $this->data; // contains your values from the constructor above
$this->load->view('clients', $data);
}
}
NOTE: Even though CodeIgniter functions default to "public", it's best practice to declare them as such. See: Public functions vs Functions in CodeIgniter
This is my first time doing web programming. I want to make one variable that I can use on some functions, I use public $username; and public $password; and use $this->username and $this->password; but it didn't work. This is my code on controller;
public $can_log ;
public function home(){
$this->load->model("model_get");
$data["results"] = $can_log;
$this->load->view("content_home",$data);
}
public function login(){
$this->load->view("site_header");
$this->load->view("content_login");
$this->load->view("site_footer");
}
public function login_validation(){
$this->load->library('form_validation');
$this->load->view("site_header");
$this->load->view("site_nav");
$this->form_validation->set_rules('username','Username','required|trim|callback_validate_credentials');
$this->form_validation->set_rules('password','Password','required|trim');// use md5 if want to encrpyt this
if($this->form_validation->run()){
redirect('site/home');
} else {
$this->load->view('content_login');
}
}
public function validate_credentials(){
$this->load->model('model_get');
$username = $this->input->post('username');//"user";
$password = $this->input->post('password');//"password";
//I tried both but none of those work
$this->can_log = $this->model_get->can_log_in($username, $password);
if($this->can_log){
return true;
} else {
$this->form_validation->set_message('validate_credentials','Incorrect username/password.');
return false;
}
}
I also tried with public $username and public $password but still can't get it
on my model;
public function can_log_in($username, $password){
$query = $this->db->query("SELECT col1, col2 FROM table1 where id_login = '$username' and id_password = '$password'");
if($query->num_rows() > 0) {
$data = $query->result(); // fetches single row: $query->row();
return $data; //fetches single column: $data->col1;
}
}
so how can I get can_log - that contains col1 and col2 - to other function?
Maybe something like this?
public function with_parameter($parameter)
{
do something with $parameter
}
And then call the function
with_parameter($can_log);
I didn't understood the exact requirements, but try below code if it works for you.
Have followed some CI guidelines which you need to learn.
Controller:
class Controller_name extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model("model_get"); // load models in constructor
$this->can_log = "some value"; // is the way to define a variable
}
public function home()
{
$data["results"] = $this->can_log; // is the way to retrieve value
$this->load->view("content_home",$data);
}
public function validate_credentials()
{
$username = $this->input->post('username');
$password = $this->input->post('password');
$is_valid = $this->model_get->can_log_in($username, $password);
if($is_valid)
{
return true;
}
else
{
$this->form_validation->set_message('validate_credentials','Incorrect username/password.');
return false;
}
}
}
Model:
class Model_get extends CI_Model
{
public function can_log_in($username, $password)
{
$where_aray = array("id_login" => $username, "id_password" => $password);
$query = $this->db->get_where("table", $where_array);
if($query->num_rows() > 0)
return $query->row();
return false;
}
}
Can something like this be done? I want to pass a variable from a public function to my view.
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->variable;
$this->load->view('home_view', $home_data);
}
public function a_function() {
public $variable = "cool";
}
//EDIT//
This is what I m actually trying to accomplish and I m stuck.
get_two gets two items from a table. I want to add the two items to two variables and pass them to the view.
public function get_two() {
$get_results = $this->home_model->get_two_brands();
if($get_results != false){
$html = '';
foreach($get_results as $result){
$html .= '<li>'.$result->brand.'</li>';
}
$result = array('status' => 'ok', 'content' => $html);
header('Content-type: application/json');
echo json_encode($result);
exit();
}
}//public function get_two() {
Should I create two functions like this? But I don't know how to pass the $get_results array from get_two to the below functions. I tried public $get_results = $this->model ... etc but that didn't work.
public function result_one() {
return $resultOne = $get_results[0];
}
public function result_two() {
return $resultTwo = $get_results[1];
}
I'm not sure I've got the question correctly but what you're trying to achieve is something like this?
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->a_function();
$this->load->view('home_view', $home_data);
}
public function a_function() {
return $variable = "cool";
}
/** AFTER EDIT **/
Things get complicated (possibly because of my english comprehension).
you said
get_two gets two items from a table. I want to add the two items to two variables and pass them to the view.
So from the function get_two() you need to get and use the result in this way?
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->get_two(); // <- here?
$this->load->view('home_view', $home_data);
}
So you can try with:
public function get_two() {
$get_results = $this->home_model->get_two_brands();
if($get_results != false){
return $get_results;
}
}
and then
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->get_two();
$this->load->view('home_view', $home_data);
}
and inside you home_view :
<?php
foreach($home_data['cool'] as $result){
echo '<li>'.$result->brand.'</li>';
}
?>
/** AFTER NEW QUESTION **/
I need the ids of the two choices as two distinct variables
So change the index function this way:
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->get_two(); // <- maybe you don't need this anymore
list($result1, $result2) = $this->get_two();
$home_data['resultId1'] = $result1->id;
$home_data['resultId2'] = $result2->id;
$this->load->view('home_view', $home_data);
}
Now you're able to use $home_data['resultId1'] and $home_data['resultId1'] inside your view.
You can also define the variable in the constructor, this is one way .
CODE:
public function __construct(){
$this->variable = "cool";
}
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->variable;
$this->load->view('home_view', $home_data);
}
I don't know the codeigniter framework so this is why I asked for a part of your view but it looks pretty simple as I check in the doc. And the doc's are not bad there.
Check for Adding Dynamic Data to the View
public_function() should return something, for ex:
function public_function() {
return 'groovy';
}
Then call it in the controller:
public function index() {
$home_data['username'] = "myname";
$home_data['cool'] = $this->public_function();
$this->load->view('home_view', $home_data);
}
Then add to the view somewhere
<?php echo $home_data['cool'];?>
I assume it's wrapped in some class. So if you cannot return the value you need (for ex. function already returns something else) then do something like this:
class Someclass {
public $some_class_variable;
function public_function() {
$this->some_class_variable = 'groovy';
}
function index() {
$home_data['cool'] = $this->some_class_variable;
}
}
