I have the following functions :
class Pharmacy extends MY_Controller {
function __construct() {
parent::__construct();
}
function index() {
$data['pack'] = $this->package();
$data['name'] = $this->getName();
$data['title'] = $this->title();
$data['name'] = $this->getName();
$data['tests'] = $this->get_tests();
$data['patient_bio'] = $this->patient_bio();
$data['procedure_name'] = $this->getProcedure();
//Pass the contents of pharmacy view to the template view.
$data1['contents'] = 'pharmacy';
$finaldata = array_merge($data, $data1);
$this->base_params($finaldata);
}
function base_params($data) {
//Load the base template for the function.
$this->output->cache(3000);
$data['title'] = 'Pharmacy';
$this->load->view('template', $data);
}
}
I want to cache the foloowing view template but when I pass the $this->output->cache(3000); it caches the whole webpage instead of caching only the template view. How can I cache only the template view ?

I am working on a blog application in Codeigniter 3.1.8.
I have a model with "static" data like the website's title, the contact email address, etc:
class Static_model extends CI_Model {
public function get_static_data() {
$data['site_title'] = "My Blog";
$data['tagline'] = "A simple blog application made with Codeigniter 3";
$data['company_name'] = "My Company";
$data['company_email'] = "company#domain.com";
return $data;
}
}
In my Posts Controller, I have tried to flow the DRY principle this way:
class Posts extends CI_Controller {
public function __construct()
{
parent::__construct();
// Load static data
$this->load->model('Static_model');
$data = $this->Static_model->get_static_data();
// Load Header
$this->load->view('partials/header', $data);
}
public function index()
{
$this->load->model('Posts_model');
$data['posts'] = $this->Posts_model->get_posts();
$this->load->view('posts', $data);
$this->load->view('partials/footer');
}
public function post($id)
{
$this->load->model('Posts_model');
$data['post'] = $this->Posts_model->get_post($id);
if (!empty($data['post'])) {
// Overwrite the default tagline with the post title
$data['tagline'] = $data['post']->title;
} else {
$data['tagline'] = "Page not found";
show_404();
}
$this->load->view('post', $data);
$this->load->view('partials/footer');
}
}
See details of how I came about writing the code above in this topic.
The problem with the above code is that the line $data['tagline'] = $data['post']->title; does no longer overwrite the static tagline $data['tagline'] = "A simple blog application made with Codeigniter 3"; with the post title. It did overwrite it when the controller look like this:
class Posts extends CI_Controller {
public function index()
{
$this->load->model('Static_model');
$data = $this->Static_model->get_static_data();
$this->load->model('Posts_model');
$data['posts'] = $this->Posts_model->get_posts();
$this->load->view('partials/header', $data);
$this->load->view('posts');
$this->load->view('partials/footer');
}
public function post($id) {
$this->load->model('Static_model');
$data = $this->Static_model->get_static_data();
$this->load->model('Posts_model');
$data['post'] = $this->Posts_model->get_post($id);
// Overwrite the default tagline with the post title
$data['tagline'] = $data['post']->title;
$this->load->view('partials/header', $data);
$this->load->view('post');
$this->load->view('partials/footer');
}
}
Bot this old version of it is goes against the DRY principle.
How can I do the desired overwrite without breaking the "DRY commandment"?
You can simply create a new property:
$this->_data or $this->staticData instead of $data
You will then be able to access/update the object property within your class.
static variable cannot be accessed outside the existing method/function
That's why when you try to update $data['tagline'] with new value, this will work but only withing your public function post($id)
http://php.net/manual/en/language.variables.scope.php
Example:
$data = $this->Static_model->get_static_data();
to
$this->data = $this->Static_model->get_static_data();
Then
$this->data['post'] = $this->Posts_model->get_post($id);
$this->data['tagline'] = $this->data['post']->title;
EDITED
Assign global variable in your model.
class Static_model extends CI_Model {
public $taglinge= "A simple blog application made with Codeigniter 3";
public function get_static_data() {
$data['site_title'] = "My Blog";
$data['tagline'] = $this->tagline;
$data['company_name'] = "My Company";
$data['company_email'] = "company#domain.com";
return $data;
}
}
In your controller:
public function post($id)
{
$this->load->model('Posts_model');
$data['post'] = $this->Posts_model->get_post($id);
if (!empty($data['post'])) {
// Overwrite the default tagline with the post title
$this->Static_model->tagline = $data['post']->title;
} else {
$data['tagline'] = "Page not found";
show_404();
}
$this->load->view('post', $data);
$this->load->view('partials/footer');
}
I'm trying to load a specific page within a controller. I followed the Codeigniter tutorial and the main pages work but the individual page (loaded with view) doesn't load according to the given slug.
blog.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Blog extends CI_Controller {
/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/index
* - or -
* http://example.com/index.php/Index/index
* - or -
*/
function __construct()
{
parent::__construct();
$this->load->model('blog_model');
$this->load->helper('url_helper');
}
public function index()
{
$data['post'] = $this->blog_model->get_posts();
$data['title'] = 'Blog archive';
$this->load->view('header', $data);
$this->load->view('blog', $data);
$this->load->view('footer', $data);
}
public function view($slug = NULL)
{
$data['post'] = $this->blog_model->get_posts($slug);
if (empty($data['post']))
{
show_404();
}
$data['title'] = $data['post']['title'];
$this->load->view('header', $data);
$this->load->view('post', $data);
$this->load->view('footer', $data);
}
}
blog_model.php
<?php
class Blog_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_posts($slug = FALSE)
{
if ($slug === FALSE)
{
$this->db->select('*');
$this->db->from('blog_posts');
$this->db->join('category', 'category.id = blog_posts.category_id');
$this->db->join('author', 'author.id = blog_posts.author_id');
$query = $this->db->get();
return $query->result_array();
}
$this->db->select('*');
// $this->db->from('blog_posts');
$this->db->join('category', 'category.id = blog_posts.category_id');
$this->db->join('author', 'author.id = blog_posts.author_id');
// $this->db->where('slug', $slug);
$query = $this->db->get_where('blog_posts', array('slug' => $slug));
return $query->row_array();
}
}
As you can see I tried a few combinations because I'm not sure it's retrieving the table in get_posts when slug is not false.
try like this
call url_helper helper in __construct like following
$this->load->helper('url');
Now, update the routes.php like following
If your URL like
http://www.example.com/blog/view/slug
Your ruote should be like this
$route['blog/view/(:any)'] = 'blog/view/$1';
If your URL like
http://www.example.com/view/slug
Your ruote should be like this
$route['view/(:any)'] = 'blog/view/$1';
And, your get_posts model function repeating queries, use it simply like below
public function get_posts($slug = FALSE){
$this->db->select('*');
$this->db->from('blog_posts');
$this->db->join('category', 'category.id = blog_posts.category_id');
$this->db->join('author', 'author.id = blog_posts.author_id');
if($slug){
$this->db->where(compact('slug'));
}
$query = $this->db->get();
return ($query->num_rows() > 1) ? $query->result_array() : $query->row_array();
}
In the end I solved it by modifying the routes:
At first I had:
$route['default_controller'] = 'Index';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['blog'] = 'blog';
$route['blog/(:any)'] = 'blog/$1';
So I changed it to:
$route['default_controller'] = 'Index';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['blog'] = 'blog';
$route['blog/(:any)'] = 'blog/view/$1';
And changed the method name in blog.php from blog to view. "view" looks more standard than "blog" so I left it that way. In 'blog/view/$1' represents the controller, view the method and of course $1 is the first param. Actually if I try Blog/view/hello-world it works too.

Hope you can have help me

I dont see any routes nor URLs that point to your Admin_Controller . If a user types http://.../admin/page Codeigniter will try to look for a controller named Admin not Admin_controller unless you have routes set up.
Also, you have this route: $route[':any'] = "page/index/$1"; This route will take any URL given and redirect the user to the Page controller (which you have not provided any code on). I would get rid of it, or what is its function?
What you need to decide is whether your admin URL should be this: http://www.my_site.com/admin/page
or this: http://www.my_site.com/admin_controller/page
Personally I would choose the first one since it looks cleaner. Which then means you have to decide whether your controller should stay named as Admin_Controller or just Admin. I would chose Admin so that you dont have to deal with routes.
The final result should be this:
Your admin URL: http://www.my_site.com/admin/page
Your Controller: application/controllers/Admin.php
class Admin extends MY_Controller {
public function __construct() {
//... your code here
}
public function page() {
//... your code here
}
}
You don't seem to have
function index()
in your admin controller.
I am building my comment module and trying to get the active records to display on view. Seems simple however I have a lot going on and using a separate model and controller then what the view is being generated from.
So I have a profile page ( where I'm trying to get the results to display )
Controller:
public function profile()
{
$this->load->helper('url'); //Include this line
$this->load->helper('date');
$this->load->library('session');
$this->load->library('form_validation');
$session_id = $this->session->userdata('id'); //Ensure that this session is valid
//TRYING TO MAKE A VARIABLE WITHT THE $_GET VALUE
$user_get = $this->uri->segment(3); // Modify this line
// LOAD THE CORRECT USER
$this->load->model('account_model');
$user = $this->account_model->user($user_get); //(suggestion) you want to pass the id here to filter your record
$data['user'] = $user;
$data['session_id'] = $session_id;
if($user_get != $user['id'] || !$user_get)
{
$data['main_content'] = 'account/notfound';
$this->load->view('includes/templates/profile_template', $data);
}
else
{
if($user_get == $session_id) //Modify this line also
{
$data['profile_icon'] = 'edit';
}
else
{
$data['profile_icon'] = 'profile';
}
$sharpie = $this->sharpie($user);
$data['sharpie'] = $sharpie;
$data['main_content'] = 'account/profile';
$this->load->view('includes/templates/profile_template', $data);
}
}
Now I have a new controller for my comments I'm trying to display:
public function airwave() {
$this->load->helper('date');
$this->load->library('session');
$airwave_get = $this->uri->segment(3);
$this->load->model('community_model');
$airwave = $this->coummunity_model->airwave($airwave_get);
$data['airwave'] = $airwave;
$data['main_content'] = 'account/profile';
$this->load->view('includes/templates/main_page_template', $data);
}
with this model:
public function airwave($id=null)
{
if(is_null($id)) {
$session = $this->session->userdata('is_logged_in');
$commenter_id = $this->session->userdata('id');
}else{
$commenter_id = intval($id);
}
$query = $this->db->query("SELECT * FROM airwaves_comments WHERE from_id=$commenter_id");
if($query->num_rows()==1)
{
$data = $query->result_array();
return $data[0];
//above returns the single row you need to the controller as an array.
//to the $data['user'] variable.
}
}
and trying to display it on this view ( which is generated by the profile function )
<div class="profile_airwave_comment_text">
<?php echo $airwave['comment'];?>
</div>
I just can't seem to get it to pass the array variable I've created properly to that view?
thanks in advance.
The first glaring thing I see wrong is in you model's airwave function:
if($query->num_rows()==1)
{
$data = $query->result_array();
return $data[0];
You are assuming that there will only be one result in your query, so if there are more or less than one, your $data array will bever be set.
Also, even then you are only returning the first element in the array. I am not seeing anywhere in your question that you want to return only one.
Finally, in your view, if you now return the full array, and not only one element, you will have to do a foreach statement.
EDIT: please see suggested solution.
In your model, don't worry about the check for the amount of data in the result array. This will come later. Simply do:
return $query->result_array();
Now, keep your controller as is, but adapt your view:
<div class="profile_airwave_comment_text">
<?php
if (isset($airwave) && is_array($airwave) && !empty($airwave))
{
foreach ($airwave as $wave)
{
echo $wave['comment'];
}
}
else
{
echo 'No comments found...';
}
?>
</div>
This should work, and if not, at least let you know that no comments were fond, and thus check your database.
HTH!
If your using HMVC, simply call the module from inside the profile view, ie:
echo Modules::run('comments/profileComments', $user->id);
Else:
You would need to create a new method in the loader class, to load in the controller seperate from routing.
If your really after a quick fix until you come up with a better alternative, you could(depending if both controllers live in the same directory) just include the 'comments' controller in your 'profile' controller and try something like this:
{Cons: CI Pagination wont work!}
application/controllers/profile.php
include 'Comments' . EXT;
class Profile extends CI_Controller{
public function __construct ()
{
parent::__construct () ;
}
public function index( $user_id ){
$commentsPartialView = call_user_func_array(array(new Comments(), "getProfileComments"), array($user_id));
return $this->load->view($this->template, array(
'view' => 'profiles/_index',
'comments' => $commentsPartialView
));
}
}
-
application/controllers/Comments.php
class Comments extends CI_Controller{
public function __construct ()
{
parent::__construct () ;
}
public function getProfileComments( $user_id ){
$user_comments = ''; //pull from DB
//set third param to TRUE for partial view, without main template
return $this->load->view('comments/show', array(
'user_comments' => $user_comments
), TRUE);
}
}
In my CI project, I would like to use a full dynamic page control. So, I’ve two controller methods, which load the php files. The model control’s queries are based on url segments. All page output generated automatically in the views php file depending on url and results of database, except index.php file.
Is this a right way?
Controller
public function index()
{
$data['title'] = "Index";
$data['nav'] = $this->content_model->get_index_nav(); //TODO
$this->load->view('templates/header', $data);
$this->load->view('templates/nav', $data);
$this->load->view('templates/nav_pict', $data);
$this->load->view('pages/aktualis', $data);
$this->load->view('templates/footer', $data);
}
public function view($page)
{
$page = 'content';
$this->load->helper('text');
$this->load->helper('url');
$page = lcfirst(convert_accented_characters(urldecode($page)));
if ( ! file_exists('application/views/pages/'.$page.'.php'))
{
show_404();
}
$data['title'] = ucfirst($page); // Capitalize the first letter
$data['nav'] = $this->content_model->get_nav();
$data['content'] = $this->content_model->get_content();
if(empty($data['content']))
{
show_404();
}
$this->load->view('templates/header', $data);
$this->load->view('templates/nav', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}
Model (Each menu has a content in database. When create a new submenu you must be add content)
public function get_content()
{
$this->db->select('content.*, mainmenu.label');
$this->db->from('content');
$this->db->join('mainmenu', 'mainmenu.id = content.katId', 'left');
$this->db->where('mainmenu.label', mysql_escape_string(urldecode(end($this->uri->segments))));
$query = $this->db->get();
return $query->result_array();
}
Routing
$route['404_override'] = '';
$route['/:any/(:any)'] = 'pages/view/$1';
$route['(:any)'] = 'pages/view/$1';
$route['Index'] = 'pages/index';
$route['default_controller'] = 'pages/index';
You're using CodeIgniter just fine, there's no need for any structure modification.
