I'm new to CI but I know CakePHP pretty well. I've searched the documentation of CI and haven't found this.
In CakePHP the fields "created" and "modified" were automatically populated by the "save" function. Does CI have two fields like that? Or can he automatically populate something?
EDIT:
Ok.. I've extended the CI_Model class and now, is there a function such as beforeSave (from cake)? And shouldn't I rather extend the DB class (I use db->set and db->insert);
Is this ok?
<?php
class spj_Model extends CI_Model {
var $table;
function __construct() {
parent::__construct();
}
function insert($data) {
$this->load->helper('date');
$data['created'] = date('Y-m-d H:i:s',now());
$data['modified'] = date('Y-m-d H:i:s',now());
return $this->db->insert($this->table,$data);
}
function update($data,$where=array()) {
$this->load->helper('date');
$data['modified'] = date('Y-m-d H:i:s',now());
return $this->db->ubdate($this->table,$data, $where);
}
}

I am new on cakephp. I have done all the required steps but still having trouble in saving data in database with cakephp
code of adduser function from Articlecontroller.php:
public function adduser()
{
$user = $this->Users->newEntity();
if ($this->request->is('post')) {
$user = $this->Users->patchEntity($user, $this->request->getData());
// Hardcoding the user_id is temporary, and will be removed later
// when we build authentication out.
$user->user_id = 1;
if ($this->Users->save($user)) {
$this->Flash->success(__('Your article has been saved.'));
return $this->redirect(['action' => 'index']);
}
$this->Flash->error(__('Unable to add your article.'));
}
$this->set('article', $user);
}
code of UserTable model:
<?php
// src/Model/Table/ArticlesTable.php
namespace App\Model\Table;
use Cake\ORM\Table;
class UsersTable extends Table
{
public function initialize(array $config)
{
$this->addBehavior('Timestamp');
}
}
Data Base Table onto my locahost:
I think you forgot to load User model in controller. It should be fixed adding this line in function adduser() before first line. It should look like this.
public function adduser()
{
$this->loadModel('Users');
$user = $this->Users->newEntity();
...
Cakephp documentation.
https://book.cakephp.org/3.0/en/controllers.html#loading-additional-models
Well, you need to have a CakePHP application that is using the plugin. You need to add $this->loadComponent('Auth'); to your AppControllers initialize() method and configure it properly.
I highly recommend you to do the complete blog tutorial of the official CakePHP documentation or you won't have much fun with any plugin or anything else in the framework. It covers setting up Auth as well.
As other have started, when not in the controller related to the table you're accessing, you need to load the model and its related entities.
The current way of retrieving a table is through the table registry, as shown below:
use Cake\ORM\TableRegistry;
// Now $articles is an instance of our ArticlesTable class. This is how CakePHP 4 prefers it.
$articles = TableRegistry::getTableLocator()->get('Articles');
// Prior to 3.6.0
$articles = TableRegistry::get('Articles');
So for your public method, it should look like this:
public function adduser()
{
$usersTable = TableRegistry::getTableLocator()->get('Users');
$user = $usersTable->newEntity();
if ($this->request->is('post')) {
...code for handling post...
}
}
The CakePHP 3.x (and beyond) documentation regarding ORM outlines this well. While $this->loadModel('Articles') work, a quick search through the docs shows it is not frequently referred to neither in ORM section nor in examples.
I am using cakephp 2.0.4 (Doing Changes in existing project)
My controller function is..
class PagesController extends AppController {
public function getlocations($string = ''){
$this->autoRender = false;
$aResult = array(0=>'Florida', 1=>'London');
echo json_encode($aResult);
}
}
And also I have try $this->autoLayout = $this->autoRender = false;
When I am calling this action directly in browser mysite/app/pages/getlocations it will give following error
View file "/home/mysite/public_html/testing/app/View/Pages/g.ctp" is missing.
Create a /View/Ajax/json.ctp view:
<?php
if(!empty($data)) echo json_encode($data);
Then in the action:
$this->set('data', array(0=>'Florida', 1=>'London'));
$this->layout = false;
$this->render('/Ajax/json');
You could also make it work following the Cake way.
First you have to add the following code to your routes file:
Router::parseExtensions('json');
Next, in the controller add the 'RequestHandler' to your components array and serialize your result in your getlocations function:
public $components = array('RequestHandler');
public function getlocations($string = ''){
$this->set('aResult', array(0=>'Florida', 1=>'London'));
$this->set('_serialize', 'aResult');
}
Finally, you can see the results in your browser mysite/app/pages/getlocations.json
Doing this way CakePHP will add the application/json headers automatically.

I am trying to modify FormHelper's behaviour to meet my application requirements. I would like to use native FormHelper but for all input I need to add some short message providing help to the user and describing the particular field.
My idea is to create my own helper and pass a help message as an argument. This function will modify form's inputDefaults setting and call a native FormHelper input function.
For example:
class MsgFormHelper extends AppHelper {
public function input($name, $message, $options) {
$this->_View->Form->_inputDefaults['after'] .= '<div>'.$message.'</div>';
return $this->_View->Form->input($name, $options);
}
}
But this solution notices this error:
Notice (8): Indirect modification of overloaded property
FormHelper::$_inputDefaults has no effect...
Is there some way how to modify "after" value in form's inputDefaults setting?
I probably found a solution (it works but I am not sure it doesn't violate some CakePHP's principles). Thanks for your opinions.
class MsgFormHelper extends AppHelper {
public function __construct(View $view, $settings = array()) {
parent::__construct($view, $settings);
}
public function input($name, $message, $options) {
$add_message = true;
if (isset($options['after'])) {
$options['after'] = trim($options['after']);
$add_message = empty($options['after']);
}
if ($add_message) {
$options['after'] = '<div class="input-help">' . $message . '</div>' . $this->_View->Form->_inputDefaults['after'];
}
return $this->_View->Form->input($name, $options);
}
}
You should be extending the FormHelper itself not AppHelper. Then in your controller use the aliasing feature so that you still use $this->Form->input() in your views but it would actually refer to your custom helper.
public $helpers = array('Form' => array('className' => 'MsgForm'))
I cannot set title_for_layout in the PagesController that comes by default with CakePHP 1.3.
I am using the following code in the display function:
$this->set('title_for_layout','some title');
What am I doing wrong?
In your controller, the corresponding value is $this->pageTitle.
UPDATE
Oops, as noted in the comments, this is the 1.2 solution. 1.3 possibilities (after doing some research) include:
Ensuring that $title_for_layout is being echoed in the layout
Placing the $this->set() code in the view rather than in the controller
If you'd like to mimic the behavior of cake 1.2, you can do the following:
In your app_controller, create the following method:
in app/app_controller.php (you may need to create this file if you haven't already)
public $pageTitle;
public function beforeRender() {
$this->set('title_for_layout', $this->pageTitle);
}
Then in any of your action methods, you may then use the pageTitle as you would in 1.2.
public function index() {
$this->pageTitle = 'Some Title';
}
The beforeRender() method will be called after your controllers have finished processing, but prior to the layout being rendered, thus allowing you to set variables for the layout.
In the action method, try this:
function index()
{
$this->pageTitle= 'Your Title';
}
Just thought I'd add to any new people finding this solution, you can do $this->set('title', $title); in CakePHP 1.3 inside the controller and the title will be rendered automatically.
You can use :
$this->assign('title', 'Some title');
and in ctp :
<title><?= $this->fetch('title'); ?></title>
It work in CakePHP 3.0
For CakePHP 3.x,
you can follow the advice here
Essentially,
Inside UsersController.php:
$this->set('title', 'Login');
Inside src/Template/Layouts/default.ctp
above the $this->fetch('title');
write:
if (isset($title)) {
$this->assign('title', $title);
}
Use beforeRender() instead. Put the following in AppController:
class AppController extends Controller {
var $content;
function beforeRender() {
$this->set('content',$this->content);
}
}
And in the controller, you can just do:
function index() {
$this->content['title'] = '123'; }
That'll do the trick.
