<?php

function __construct()

// Call the Model constructor
parent::__construct();
}
function getAll()
{
$q=$this->db->get('test'); // query where 'test' is table name.
if($q->num_rows()>0)
{
foreach ($q->result() as $row)
{
$data[]=$row;
}
return $data;
}
}
}
?>
$records already holds your data so this should work:
foreach($records as $row){
echo $row->title;
}
You do not need to use result() in your view,because in your model you already did.
Just try this:
<?php
foreach($records as $row):
echo $row->title;
endforeach;
?>

I call the index() method of the collaborating controller, it automatically inserts 6 records into the database, and the action of logging into the database is not in the cadastrarquestao() method of the class, and not in the index method . I'm using a template library.
Controller Colaborador:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Colaborador extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->helper('url');
$this->load->helper('funcoes_helper');
$this->load->helper('file');
$this->load->helper('cookie');
$this->load->library('session');
$this->load->library('controle_acesso');
$this->load->model('resumoapp_model', 'resumo');
$this->load->model('homeapp_model', 'homeapp');
$this->load->model('simulado_model', 'simulado');
$this->controle_acesso->acesso();
$this->output->enable_profiler(TRUE);
}
public function index() {
$dados['teste'] = 1;
$this->template->load("template/template_app",'app/enviar-questao', $dados);
}
public function logout() {
session_unset();
redirect ('/entrar');
}
public function cadastrarquestao() {
$this->simulado->envioquestao(1);
$dados['mensagem'] = "dados cadastrados com sucesso!";
$this->template->load("template/template_app",'app/enviar-questao', $dados);
}
public function materia() {
}
}
part of the code
public function envioquestao($dados) {
$data = [
'Id_usuario' => $this->session->userdata('id_usuario'),
];
$this->db->insert('teste',$data);
}
librarie Template:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Template {
var $template_data = array();
function set($name, $value)
{
$this->template_data[$name] = $value;
}
function load($template = '', $view = '' , $view_data = array(), $return = FALSE)
{
$this->CI =& get_instance();
$this->set('contents', $this->CI->load->view($view, $view_data, TRUE));
return $this->CI->load->view($template, $this->template_data, $return);
}
}
View template:
<html lang="pt-br">
<?php
$this->load->view('app/header');
?>
<body>
<div class="wrapper">
<?php
$this->load->view('app/topo');
?>
<?php
$this->load->view('app/menu');
?>
<?php echo $contents ?>
<footer class="footer-container"><span>© </span></footer>
</div>
<?php
$this->load->view('app/footer');
?>
</body>
</html>
the correct one would be to insert it in the database after clicking on 'register' which is in the cadastrarquestao() method

I am new in ci. In controller i.e. Test.php I am defining $stream='agriculture' and pass $stream variable to top_agriculture_exams model. Now, when I am fetching data on header.php file it show me a Message: Undefine variable: $exam I don't know why. So, how can I fix it ?please help me.
Thank You
Please check my below code. This will help you.
<ul class="list">
<?php
if ($exam !== NULL):
foreach ($exam as $row):
echo "<li><a href='#'>" . $row['exam_name'] . "</a></li>";
endforeach;
endif;
?>
</ul>
Also cna you please put this code in View and share result.
<?php
var_dump($exam);
?>
Also check your model code below.
<?php
class Fetch_data extends CI_Model
{
function __construct()
{
parent::__construct();
}
public function top_agriculture_exams($stream)
{
$this->db->select('exam_name');
$this->db->from('all_exams_details');
$this->db->where('exam_name',$stream);
$this->db->order_by('exam_name');
$this->db->limit('10');
$query = $this->db->get();
$result = $query->result_array();
return $result;
}
}
instead of accessing it using the element array try accessing it using object.
change below code in your Fetch_data.php file.
//$result = $query->result_array();
$result = $query->result();
and access it by object in your header.php. here's an example below.
<ul class="list">
<?php foreach($exam as $row): ?>
<?= "<li><a href='#'>" . $row->exam_name . "</a></li>" ?>
<?php endforeach;
</ul>
where exam_name is equal to the column in your database.

anyone please help me to retrieve the db data and how to view it in html table.is the coding i given is correct or not if not can you please say how i have to give. in order to view it in html table.
Controller
class edit_content extends CI_Controller {
function edit_content()
{
parent::__construct();
$this->load->model('editcontent_model');
$this->load->helper('url');
$this->load->library('acl');
$this->data = $this->editcontent_model->get_contents();
}
}
View
<table>
<tr>
<th>Content</th>
</tr>
<?php foreach($this->data as $r): ?>
<tr>
<tr><?php echo $r['content']; ?>
</tr>
<?php endforeach; ?>
<table>
Model
class editcontent_model extends CI_Model {
var $CI;
function editcontent_model(){
parent::__construct();
}
function get_contents() {
$this->db->select('content');
$this->db->from('contents');
$query = $this->db->get();
return $result = $query->result();
$this->load->view('edit_content/edit_content', $result);
}
}
Try this:
<?php
#mycontroller
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class edit_content extends CI_Controller {
public function __construct(){
parent::__construct();
}
function edit_content()
{
$data = array();
$this->load->model('editcontent_model');
$this->load->helper('url');
$this->load->library('acl');
$data['result'] = $this->editcontent_model->get_contents();
$this->load->view('edit_content/edit_content', $data);
}
}
?>
<!-- myview -->
<table>
<tr>
<th>Content</th>
</tr>
<?php foreach($result as $r): ?>
<tr><?php echo $r->content; ?>
</tr>
<?php endforeach; ?>
</table>
<?php
#mymodel
class editcontent_model extends CI_Model{
function get_contents() {
$this->db->select('content');
$this->db->from('contents');
$query = $this->db->get();
return $result = $query->result();
}
}
Put this in the end of your edit_content function in your controller
$this->load->view('edit_content/edit_content', $result);
Loading of the view should be done in the controller. From what I see, your model have returned the result so the last line is not executed.
Do this in your edit_content function
$result=$this->editcontent_model->get_contents();
$this->load->view('edit_content/edit_content', $result);
and in your view, access the content like:
<?php foreach($result as $result): ?>
<tr>
<tr><?php echo $result[0]->content; ?>
</tr>
<?php endforeach; ?>
You have to do this beacuse the $result is an associative array not a simple one.
Hope this helped you.
I am using CI for my web-site. While programming CMS for the same I faced no problem but when I am programming the same for user-end I am getting error as:
"404 Page Not Found
The page you requested was not found."
What am i doing wrong?? Any help/suggestions is warmly welcome.Thank you.
In Controller(model.phpl):
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Model extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('user_model');
$this->load->model('common');
$this->load->model('home_model');
$this->load->model('page_model');
}
function _remap($method , $params = array())
{
$this->menu = $this->common->createMenuArr();
$this->index();
}
function index()
{
$data['sliderArr'] = $this->user_model->sliders();
$this->load->view('index', $data);
}
}
In Model(user_model.php):
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class User_model extends CI_Model{
function __construct()
{
parent::__construct();
//$this->load->database();
}
function sliders()
{
$query = $this->db->query("SELECT slider FROM tbl_sliders ORDER BY slider_id DESC")->result_array();
return $query;
}
}
and finally in view(index.php):
<div id="slideContainer">
<div id="slideShim">
<?php
if(!empty($sliderArr))
{
foreach($sliderArr as $slider)
{ ?>
<img src="<?php echo base_url();?>images/sliders/<?php echo $slider['slider'];?>"
<?php }
}
?>
</div>
</div>
Go to Application -> Config -> Routes.
And Set $route['default_controller'] = "index"; //whatever your controller name is on which you want your application to route by default
Hope this helps.
