I'm new at this and some help will be apprciated.
I'm building a sidebar in a CI-Boilerplate-Project which contains modules (widgets) that i got run with HMVC https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc.
In the sidebar i have a widget that display a friendslist with status online/offline.
The user has the ability to switch the widgets on/off in the managementsection.
In the Profileview:
<aside class="sidebox right">
<?php foreach ($boxes as $boxName => $boxSetting)
{
echo Modules::run($boxName, $boxSetting['box_visible']);
}
?>
</aside>
if box_visible == 1 the widget will be displayed.
Controller:
class Myfriends extends SM_Controller
{
function __construct()
{
parent::__construct();
}
public function index($visible = false)
{
$user = $this->session->userdata('user');
$myf = $this->widget_model->get_friends($user['user_id'], 5);
$data['friends'] = $myf;
if ($visible) $this->load->view('myfriends', $data);
}
}
View:
<html>
<head>
<meta http-equiv="refresh" content="5">
</head>
<body>
<div class="box friendsbox">
<div id="header"><h3><?=$boxTitle?></h3></div>
<div id="boxcontent">
<ul>
<?php foreach ($friends as $friend): ?>
<li>
<div id="thb_img">
<img src="<?=img_thumb($friend['file_path'], 50, 50) ?>" />
</div>
<div id="short_desc">
<a href="<?= site_url('widget_functions/show_user/' . $friend['uu_id']) ?>">
<?= ucfirst($friend['user_name']) . ' ' . ucfirst($friend['user_lastname']) . ' ' ?>
</a>
<?php if ($friend['is_online']): ?>
<span style="color: green">online</span>
<?php endif; ?>
</div>
</li>
<?php endforeach; ?>
</ul>
</div>
<div id="footer">ยป mehr</div>
</div>
</body>
</html>
Now, i need to update the friendslist every 1-2 min so i tryed to load the moduleview within an iframe:
<aside class="sidebox right">
<?php foreach ($boxes as $boxName => $boxSetting): ?>
<?php if ($boxName == 'myfriends' && $boxSetting['box_visible'] == 1) { ?>
<iframe src="<?php echo site_url('myfriends/index'); ?>" ></iframe>
<?php
}
else
{
echo Modules::run($boxName, $boxSetting['box_visible']);
}
?>
<?php endforeach; ?>
</aside>
BUT this dose not work! The place of the widget is emtpy.
Do you have any idea how to get that to work?
appreciate your help
I believe the main issue is with the way you initialize the index method. the index method is kinda tricky with parameters in Codeigniter. In my projects, the only way to get the vlues of arguments passed to the index parameters is by using the URI library method $this->uri->segment(n). In other words, I believe that the value of $visible is not properly passing to the index() body
Anyway, I think you should create another method in your MyFriends Class called render() for example, and call it instead of relaying on the index() method. now render() can play nicely with the $visible=false initialization trick.
Hope this helps

How do I check if my database has more than 9 entries, and if it has, I can advance to the next page.
Currently I have this code, but I don't know how to call that in my view:
Here in the controller I have already called the checklogin and see if it has more than 9 entries.
Controller:
function quizzes(){
$this->load->model('Quiz_Model');
$data['categorys'] = $this->Quiz_Model->SearchAllCategorys();
$this->load->view('headerLogged');
$this->load->view('quizzes', $data);
$this->load->view('footer');
}
function proses_quiz($id_category){
$this->load->view('headerLogged');
$checkquiz=$this->Quiz_Model->checkquiz($id_category);
if($checkquiz > 9){
redirect('User_Ctr/quiz/').$id_category;
}else{
$data['error_quiz']="MEH";
$this->load->view('quizzes', $data);
}
$this->load->view('footer');
}
And here it's just the code to make the count:
Model:
public function checkquiz($id_category){
$this->db->select('id_question, COUNT(id_question) as total');
$this->db->from('questions');
$this->db->where('id_category', $id_category);
$result = $this->db->get();
return $result->result();
}
View:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
?>
<div class="container">
<h1 class="my-4 text-center text-lg-left">Quizzes</h1>
<div class="row text-center text-lg-left">
<?php foreach($categorys as $cat): ?>
<div class="col-lg-3 col-md-4 col-xs-6" >
<a href="<?php echo 'quiz/'.$cat->id_category ?>" class="d-block mb-4 h-100" >
<img class="img-fluid img-thumbnail" src="<?php echo $cat->img_category ?>" alt="" style="height: 125px; width: 400px">
<?php
if(isset($error_quiz)){
echo $error_quiz;
}
?>
</a>
</div>
<?php endforeach ?>
</div>
</div>
I will answer you question generally.
If you want to call something in the view you have many options like you have the variable already calculated in advance and already passed it to view waiting for a call, or you can click on a link that maybe reload the current view with the new variable done, or you can use ajax to go get the variable from the controller without reloading.
So if the variable has fixed value that doesn't depend on your action, go with the first option or else chose one of the others.
On the Homepage I have called the content of Custpm Post Type with Ajax with this code
jQuery(document).ready(function($){
$.ajaxSetup({cache:false});
$(".sector_item a").click(function(){
var post_link = $(this).attr("href");
$(".sector_item_content").html("<div class='load' style='position:relative;margin-top:50px;padding-bottom:50px;'><img src='<?php bloginfo("template_url"); ?>/images/ajax-loader.gif'></div>");
$(".sector_item_content").load(post_link);
return false;
});
});
But In the single Page of this same Post Type I need to have another design with content so how I can detect the single page. I tried with Wordpess is_single() function but it doesnt work it displayed anyway in ajax.How Can I fix this?
Here is my single template.php
<?php if(is_singular('sector' )){
echo 'Single page' ;
}else{
while (have_posts() ) : the_post(); ?>
<div class="container single_page_inner">
<div class="row clearfix">
<div class="col-md-10 column" style="float:none;margin:auto;">
<div class="sector_single_title">
<?php the_title();?>
</div>
<div class="single_sector_contentmain"> <?php the_content();?></div>
<div class="single_sector_more">
<img src="<?php bloginfo(template_url);?>/images/single_secormoreline.png"/>
<div class="single_sector_button">
<span class="single_sec_leftline"></span>
<span class="single_sec_rightline"></span>

<?php endwhile; ?>
If you want to be able to do different things when your single.php files is loaded from Ajax, you need to tell it somehow when it is getting an Ajax request.
One approach would be to add a parameter to your call, like this:
var post_link = $(this).attr("href") + '?isajax=1';
Then in your single.php file, test for this parameter:
<?php if(!empty($_GET['isajax'])){
// This is Ajax - display in Ajax format
} else {
// This is not Ajax - display in standard single.php format
}
use this:
is_singular('YOUR_POST_TYPE' );

i have a right menu in my ci blog site that contains categories and no. of post that is subjected to change, has the following format,
Categories:
Science(24)
education(32)
....
....
the number is brackets is the total amount of post in that category.
my template file is here:
$this->load->view('includes/header');
$this->load->view($main_content);
$this->load->view('includes/footer');
And my right menu is in the footer file.
How could i achieve this?
you better have a main view divided into divs(header, main_content,footer,right_menu) always loaded and load each view in the appropriate div.
<html>
<body>
<div id="header">
<?php $this->load->view('header'); ?>
</div>
<div id="body">
<div id="top_menu">
<?php $this->load->view('top_menu'); ?>
</div>
<div id="main_content">
<?php $this->load->view('main_content'); ?>
</div>
</div>
<div id="footer">
<?php $this->load->view('footer'); ?>
</div>
</body>
</html>
You can also use this system for including header/footer etc:
<?php
/**
* /application/core/MY_Loader.php
*
*/
class MY_Loader extends CI_Loader {
public function template($template_name, $vars = array(), $return = FALSE)
{
$content = $this->view('templates/header', $vars, $return);
$content .= $this->view($template_name, $vars, $return);
$content .= $this->view('templates/footer', $vars, $return);
if ($return)
{
return $content;
}
}
}
Then, in your controller, this is all you have to do:
<?php
$this->load->template('body');

i'm in the middle of creating a website and i want to creat a dynamic dropdown menu.The problem is that when i load the entries from the database only the first entry is displayed correctly , the other entries in the menu are displayed as code. I'm using Xamp with PHP 5.3 and HeidiSql.This is my code :
<div id="1" class="mega solidblocktheme">
<div class="column">
<ul>
<li><a href="<?php include('../conect.php'); $result=mysql_query("SELECT * FROM tours");
while($data=mysql_fetch_row($result))
{ echo $data[2]; ?>"> <?php echo $data[1];
echo "</a></li>"; }
mysql_close($con);?>
</ul>
</div>
</div>
Your loop seems to be in the wrong place. Try something like this:
<ul>
<?php include('../conect.php');
$result=mysql_query("SELECT * FROM tours");
while($data=mysql_fetch_row($result))
{
echo '<li><a href="'.$data[2].'">'.$data[1];
echo "</a></li>";
}
mysql_close($con);?>
</ul>
You should not do it this way .
while($data=mysql_fetch_row($result))
{ echo $data[2]; ?>">
echo ""; }
For every loop , you are just adding content and close tags </a> and </li>
But you are not adding start tags for them .
What you can do is , first store your data result in a string
include('../conect.php');
$result=mysql_query("SELECT * FROM tours");
$data=mysql_fetch_row($result);
mysql_close($con);
$list = "";
foreach($data as $data_key) {
$list.= '<li> '.$data[1].' </li>';
}
So now you got your list
After that comes your HTML , just echo your built string
<div id="1" class="mega solidblocktheme">
<div class="column">
<ul>
<?php
echo $list;
?>
</ul>
</div>
</div>
I display a random post loop on a page. I'd like to put a "refresh" link to refresh the content of the loop via ajax.
Is this possible?
This is my loop:
<ul id="content-inner" class="thumb-grid clearfix">
<?php query_posts('posts_per_page=20&orderby=rand'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<li>
<a href="<?php the_permalink(); ?>">
<img src="<?php echo $my_image_url = get('thumbnail'); ?>" alt="" />
<span class="title"><?php the_title(); ?></span>
<span class="feat"><?php $articletags = strip_tags(get_the_tag_list('',', ',''));echo $articletags;?></span>
</a>
</li>
<?php endwhile;?>
<?php endif; ?>
<?php wp_reset_query(); ?>
</ul>
Thanks
Put the random post code in a div (if you haven't already), and refresh the contents of that div with JQuery...
Something like this should work (but I haven't had time to test)...
In the Head of your page reference JQuery, then use JQuery.Ready to load the first random post (for initial page load):
<head>
<script> /*...reference JQuery...*/ </script>
<script>
jQuery(document).ready(function($) {
$("#randomdiv").html("<?php getRandomPost() ?>");
});
</script>
</head>
<body>
....
<div id="randomdiv">[placeholder text]</div>
<a id="refresh" href="#">click</a>
<!-- Then for the REFRESH:
make sure this script occurs AFTER your div (above) -->
<script>
$(function() {
$("#refresh").click(function(evt) {
$("#randomdiv").html("<?php getRandomPost() ?>");
evt.preventDefault();
})
})
</script>
</body>
So put your entire loop code in a function called getRandomPost() (or something) and place it in your wordpress "functions.php" file..., then just call "$("#randomdiv").html("");" in the head of your page for initial load, then in the body as I've shown for the refresh...
