I have write a some codeigniter code, when I click button add a data, and the table will ajax reload, not reload the page. How to modify my code? Thanks
This is my controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Big_category extends CI_Controller {
function __construct() {
...
}
function index() {
if($this->session->userdata('logged_in')) {
$this->page(0);
} else {
show_404('page');
}
}
function page($page) {
....
$data['pagelist']=$this->pagination->create_links();
$data["main_content"] = "big_category_view";
$this->load->view('template', $data);
}
This is my model
class Big_category_model extends CI_Model
{
...
function get_big_category($limit, $start)
{
$this->db->limit($limit, $start);
$query = $this->db->get_where('category1', array('c1_status' => 1)); //SELECT * FROM category1
return json_encode($query->result());
}
This is my view
...
<? $data = json_decode($all_big_category); ?>
<? foreach($data as $key => $value): ?>
<tr class="modify_tr">
<td><?=($key+1)?></td>
<td id="td_id_<?=$value->c1_id?>" class="modify_td">
<span id="c1_id_<?=$value->c1_id?>"><?=$value->c1_name?></span>
<form class="form-search td_id_<?=$value->c1_id?>">
<input type="text" name="input_c1_id" id="input_c1_id_<?=$value->c1_id?>">
<button class="btn modify" id="button_c1_id_<?=$value->c1_id?>" c1-id="<?=$value->c1_id?>" type="button"><i class="icon-edit"></i></button></td>
</form>
<td><button class="btn btn-danger"><i class="icon-remove-sign"></i></button></td>
</tr>
<? endforeach ?>
</table>
<?=$pagelist?>
...
Here is a simple technique of how you can achieve this.
Layout(Template)
<html>
<body>
<div><!--other stuff here--></div>
<div id = 'form_id'>
<?php echo $content?>
</div>
</body>
</html>
Controller
function index()
{
if($this->input->is_ajax_request()){
//load form here
$this->load->view('form');
}else{
//this will load the form for the first time
//pass third parameter as TRUE so it will returned as string
//assigned to index content which will be displayed in layout
$data['content'] = $this->load->view('form',$data , TRUE);
//load template here
$this->load->view('template', $data);
}
}
JQuery
$.ajax({
type : 'POST',
url : '<?php echo site_url('controllername/index')?>',
data : '' // query string
success : function(formagain){
$('#form_id').html(formagain);
//this will replace the content of div with new form
}
});

Controller:
public function latestnews()
{
$data['news'] = $this->New_model->getById($id);
$this->load->view('news',$data);
}
Model:
public function getById($id)
{
return $this->db->get_where($this->_table, ["new_id" => $id])->row();
}
View:
<?php
if (isset($news) and $news) {
foreach($news as $new) {
?>
<div class="col-sm-12">
<div class="section">
<img src="<?php echo site_url('uploads/'.$new->image); ?>" />
</div>
<p><?php echo $new->description;?> </p>
</div>
<?php
}
}
?>
How and where to define the variable id?
While clicking a dynamic image,it should be opened in another page containing details but instead showing Undefined variable: id
In the latestnews() function you have no $id defined.
Try to call the latestnews() function with the right $id parameter.
you can write function like this,
function latestnews($id)
{
Controller:
function single_news($id) { // This $id variable comes from URL Ex: example.com/single_news/15. So $id = 15
$this->data['news_data'] = $this->new_model->getNewsByID($id);
$this->load->view('single-news', $this->data); // Create New View file named single-news.php
}
Model:
function getNewsByID($id) {
$this->db->where('id', $id);
$q = $this->db->get('news');
if($q->num_rows() > 0) {
return $q->row();
}
return false;
}
View: (Single News Page)
<div>
<img src="<?php echo site_url('uploads/'.$news_data->image); ?>" />
</div>
I am creating a sample image test where in I want to display all of the images in a database table in CodeIgniter. The question is, how will I able to display the values of the database table using CodeIgniter?
Here is the code of my model:
<?php
class Image_model extends CI_Model{
/*Sample test function for the image dropdown list*/
public function getImages()
{
$query = $this->db->select('main_image_url'));
$this->db->get('product_master');
return $query->result();
}
/*End sample test function*/
}
?>
Here is the code of my controller:
<?php
if(! defined('BASEPATH')) exit('No direct script access allowed');
class Sample_image_dropdown extends MX_Controller{
public function __construct()
{
parent::__construct();
}
public function index()
{
$data['main_view'] = 'sample_view/image_dropdown_view';
$this->load->view('sample_view/image_dropdown_view', $data);
}
public function display_all_images()
{
$this->load->model('sample_model/image_model');
$data['images'] = $this->image_model->getImages();
$data['main_view'] = "sample_view/image_dropdown_view";
$this->load->view('sample_view/image_dropdown_view', $data);
}
}
?>
Here is the code of my view:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div>
<select name="" id="">
<option value="all">All Image</option>
<option value="with-image">With Image</option>
<option value="no-image">Without Image</option>
</select>
<input type="submit" value="Search">
</div>
<?php if (isset($images)):?>
<?php foreach ($images as $image):?>
<table>
<tr>
<td>
<th>
Images
</th>
</td>
</tr>
<tr>
<td>
<img src="<?php echo "$image->main_image_url";?>">
</td>
</tr>
</table>
<?php endforeach; ?>
<?php endif; ?>
</body>
</html>
You made a mistake in your model and in the controller, I mentioned the changes please note down and try,
Model File
class Image_model extends CI_Model{
/*Sample test function for the image dropdown list*/
public function getImages()
{
$query = $this->db->select('main_image_url');
$this->db->from('product_master');
$query = $this->db->get();
return $query->result();
}
/*End sample test function*/
}
Controller File,
public function __construct()
{
parent::__construct();
}
public function index()
{
$data['main_view'] = 'sample_view/image_dropdown_view';
$this->display_all_images();
}
public function display_all_images()
{
$this->load->model('sample_model/image_model');
$data['images'] = $this->image_model->getImages();
$data['main_view'] = "sample_view/image_dropdown_view";
$this->load->view('sample_view/image_dropdown_view', $data);
}
I assume you are storing images in directory at the time of uploading at
uploads/abc.png
then you can get data from db (which you are already doing)
and in view :
<img src="echo dir_path./$image->main_image_url;" />
or if you are storing whole path in DB then :
<img src="echo $image->main_image_url;" />
So I'm in the middle of creating an E-Commerce site for a class. On my Profile page I'm planning to display various info stored in the db. Right now I'm only messing with the user photo. I have a function in the model that gets the Users photo from the column 'Image_Path' in DB 'users'. My problem is that for each profile view it shows the same photo. I think its return the whole array of pictures and maybe just sets it as the first one?
here is the model
<?php
class Profile_Model extends CI_Model
{
public function __construct()
{
$this->load->database();
}
// public function get_profile_picture()
// {
//
// $query = $this->db->get('users');
// return $query -> result();
// }
public function get_single_profile($id){
//get whole table
$this->db->select('Username');
$this->db->select('Image_Path');
$this->db->from('users');
$this->db->where('User_ID', $id);
$query = $this->db->get();
return $query->result();
}//end get_single_profile
//for uploading profile pics
public function set_profile_pic(){
}
}//CLASS
?>
The Controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Profile extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
$this->load->library('session'); //needed to use global session variables
$this->load->helper('language');
$this->load->model('Profile/Profile_Model');
}
public function index()
{
if($this->session->userdata('logged_in'))
{
$data['profilepicture'] = $this->Profile_Model->get_single_profile();
$this->load->view('Profile/Profile', $data);
}// echo session variable logged_in
else{
redirect( base_url().'Login'); //redirect to user profile view after verification)
}
}//END Index
public function logout(){
$this->session->sess_destroy();
redirect(base_url(). 'Login');
}//END LOGOUT
public function display_profile_pic(){
$data['profilepicture'] = $this->Profile_Model->get_profile_picture();
$this->load->view('Product/Product', $data);
}
}//END CLASS
The View
<!DOCTYPE html>
<html>

First, try changing the select portion of your query. It should be like:
$this->db->select('Image_Path, Username');
if it still not working, try to echo your last query in get_single_profile()
echo $this->db->last_query();
exit;
Changed my Model function to:
public function get_single_profile($id){
//get whole table
$this->db->select('Image_Path');
$this->db->from('users');
$this->db->where('Username', $id);
$query = $this->db->get();
echo $this->db->last_query();
return $query->result();
}//end get_single_profile
And My Controller Index To:
public function index()
{
if($this->session->userdata('logged_in'))
{
$data['profilepicture'] = $this->Profile_Model->get_single_profile($this->session->userdata('logged_in') );
$this->load->view('Profile/Profile', $data);
}// echo session variable logged_in
else{
redirect( base_url().'Login'); //redirect to user profile view after verification)
}
}//END Index
in the model I changed the Username from the table and set it to $id, In the controller I used a previously defined session variable to set $id to the session...I think
I need to reload a content of my Yii widget via AJAX every XX seconds.
This is my widget code:
class UserOnlineWidget extends CWidget
{
public function init(){
}
public function run(){
$userOnline=User::getOnlineUser();
$this->render("userOnLineWidget", array('userOnline'=>$userOnline));
}
}
And this is the view userOnLineWidget.php:
<div class="userOnline">
<h5>User Online</h5>
<ul>
<?php
foreach($userOnline as $user) {
?>
<li>
<ul>
<li><?php echo CHtml::link($user['username'], array('/site/view/'.$user['id'])); ?></li>
<li><?php echo ($user['online'] != null)? 'online' : 'offline'; ?></li>
</ul>
</li>
<?php
}
?>
</ul>
</div>
How can I do this ? I use Yii 1.1.
Here a small example. I hope this help you. Widget which show time from server every second.
//SiteController
public function actionTest()
{
$this->render('my_view'); //just rendering view
}
public function actionContent()
{
$this->widget('time'); //return html of widget. use for ajax
}
//my_view.php
<script src="<?php echo $this->assetsBase ?>/js/jquery-1.10.2.js"></script>
<script type="text/javascript">
$(document).ready(function() {
setInterval(function() {
$.get('/site/content', {}, function(data) {
$('#widget').html(data);
});
}, 1000); //update widget content every second
});
</script>
<div id="widget">
<?php $this->widget('time'); // render widget ?>
</div>
//widget
class Time extends CWidget
{
public function init(){
}
public function run(){
$date = new DateTime();
$this->render("test", array('time'=>$date->format('H:i:s')));
}
}
//view for widget test.php
<p><?= $time ?></p>
I am a newbee to CodeIgniter and PHP. I am trying to insert data using a form and display it on the same view page using MVC pattern given by CodeIgniter. My View is:
<html>
<head>
<title>My Form</title>
</head>
<body>
<? echo form_open('books/input'); ?>
<? echo $id; ?>:
<? echo form_input('id'); ?>
</br>
<? echo $title; ?>:
<? echo form_input('title'); ?>
</br>
<? echo $body; ?>:
<? echo form_input('body'); ?>
</br>
<? echo form_submit('mysubmit','Submit!'); ?>
<? echo form_close(); ?>
</body>
</html>
and My Controller is:
<? class Books extends Controller{
function Books(){
parent::Controller();
}
function main(){
$this->load->model('books_model');
$data = $this->books_model->general();
//$this->load->view('books_main',$data);
}
function input(){
$this->load->helper('form');
$this->load->model('books_model');
$data = $this->books_model->general();
$this->load->view('books_input',$data);
}
} ?>
and My model is just returning the data entered by the user as:
<? class books_model extends Model{
function books_model(){
$this->load->helper('url');
}
function general(){
$data['id'] = 'id';
$data['title'] = 'title';
$data['body'] = 'body';
return $data;
}
} ?>
But when I try to access the form, it shows me an error quoting:
load->model('books_model'); $data = $this->books_model->general(); }
function input(){ $this->load->helper('form'); $this->load->model('books_model'); $data = $this->books_model->general();
$this->load->view('books_input',$data); } } ?>
404 Page Not Found
though I am accessing it with the same URL: localhost/CodeIgniter/index.php/books/input
How can I access this form and insert data successfully?
Every Class name should start with capital letter
like
class Books_model extends Model
and do type like this
$this->load->model('Books_model');
this could be the issue that you are getting "404 page not found".
