I want to display data on the controller
public function __construct() {
parent:: __construct();
if(!isset($_SESSION)){
session_start();
}
if (!$_SESSION['logged_in']) {
redirect('auth/login');
}
$managemenu = new Managemenu();
$get_data = $managemenu->index($_SESSION['admin_level'],$GLOBALS['PAGE_DISTRIK']);
if(empty($get_data['validPage'])){
redirect('auth/login');
}
$this->getdata = $get_data;
$this->load->model('Model_distrik');
}
public function index()
{
$data['page'] = 'v_distrik';
$data['title'] = 'List Distrik';
$data['menu'] = $this->getdata['menu'];
$data['distrik'] = $this->Model_distrik->getDataDistrik();
echo "<pre>";
print_r ($data['distrik']);
echo "</pre>";
die();
$this->load->view('main',$data);
}
I've tried a number of times but the results are like
this error message: undefined property: district :: $ model_district
class Model_distrik extends CI_Model {
public function getDataDistrik(){
$this->db->select('*');
$this->db->from('distrik');
$this->db->where("Deleted", 0);
$query = $this->db->get()->result_array();
return $query;
}
}

I have a site built with CakePHP, default it doesn't allow subdomain embed on iframe.
I configured Frame Option on nginx/conf.d and now my homepage can be embedded in an iframe of a subdomain.
However, another post cannot be embedded on a subdomain's iframe. (exp: http://example.net/postabc will not display). I tried to change options on Header security middleware(please read below).
Is there anywhere I need to change the configuration to so all my posts can be displayed?
<?php
namespace Cake\Http\Middleware;
use InvalidArgumentException;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
class SecurityHeadersMiddleware
{
protected $headers = [];
public function noSniff()
{
$this->headers['x-content-type-options'] = 'nosniff';
return $this;
}
public function noOpen()
{
$this->headers['x-download-options'] = 'noopen';
return $this;
}
public function setReferrerPolicy($policy = 'same-origin')
{
$available = [
'no-referrer', 'no-referrer-when-downgrade', 'origin',

'unsafe-url'
];
$this->checkValues($policy, $available);
$this->headers['referrer-policy'] = $policy;
return $this;
}
public function setXFrameOptions($option = 'allow-from', $url = 'http://subdomain.example.net')
{
$this->checkValues($option, ['deny', 'sameorigin', 'allow-from']);
if ($option === 'allow-from') {
if (empty($url)) {
throw new InvalidArgumentException('The 2nd arg $url can not be empty when `allow-from` is used');
}
$option .= ' ' . $url;
}
$this->headers['x-frame-options'] = $option;
return $this;
}
public function setXssProtection($mode = 'block')
{
$mode = (string)$mode;
if ($mode === 'block') {
$mode = '1; mode=block';
}
$this->checkValues($mode, ['1', '0', '1; mode=block']);
$this->headers['x-xss-protection'] = $mode;
return $this;
}
public function setCrossDomainPolicy($policy = 'all')
{
$this->checkValues($policy, ['all', 'none', 'master-only', 'by-content-type', 'by-ftp-filename']);
$this->headers['x-permitted-cross-domain-policies'] = $policy;
return $this;
}
protected function checkValues($value, array $allowed)
{
if (!in_array($value, $allowed)) {
throw new InvalidArgumentException(sprintf(
'Invalid arg `%s`, use one of these: %s',
$value,
implode(', ', $allowed)
));
}
}
public function __invoke(ServerRequestInterface $request, ResponseInterface $response, $next)
{
$response = $next($request, $response);
foreach ($this->headers as $header => $value) {
$response = $response->withHeader($header, $value);
}
return $response;
}
}
This is the code
My Controller file
public function view_resume($id)
{
$this->load->model('ORB_Model');
$data['get_masterData'] = $this->ORB_Model->get_masterData($id);
}
My Model file:
public function get_educationData($id)
{
return $this->db->get_where('edu_tb',['edu_id'=>$id],2)->result_array();
}
My View File:
<?php
print_r($get_educationData);
die;
// output array()
foreach ($get_educationData as $key){
?>
value="<?php echo $key->['edu_name']; ?>"
<?php
}
?>
Now when i print_r my $get_educationData it will give empty array() only.
my data is not coming from model.
in my view file nothing shown there.
Your controller should be like this :
You have to call get_educationData method also in your controller like this :
public function view_resume($id)
{
$this->load->model('ORB_Model');
$data['get_masterData'] = $this->ORB_Model->get_masterData($id);
$data['get_educationData'] = $this->ORB_Model->get_educationData($id);
/* load view here like this */
$this->load->view('your_view' ,$data);
}
Your model get_educationData should be like this :
public function get_educationData($id)
{
if ( ! empty($id))
{
$query = $this->db->get_where('edu_tb', array('edu_id' => $id));
}
else
{
$query = $this->db->get('edu_tb');
}
if ($query->num_rows() > 0)
{
return $query->result_array();
}
}
Your view should be like this :
Instead of object notation use array since your return data is in array form
<?php
//print_r($get_masterData);
//print_r($get_educationData);
if ( ! empty($get_educationData))
{
foreach ($get_educationData as $item)
{
echo $item['edu_name'];
}
}
?>
I really need to know this issue to finish my work.
Here I'll give a example envolving model and controller.
I want to pass $final_name from controller to beforeSave() of my model
public function admin_add() {
if($this->request->is('post')) {
if($this->data['Client']['file']['tmp_name'] != '') {
// Upload block
$tmp_file = $this->data['Client']['file']['tmp_name'];
$file = new File($tmp_file);
if($file->mime() == "image/jpeg" or "image/png") {
$ext = explode('.', $this->data['Client']['file']['name']);
$name = md5($this->data['Client']['file']['name']);
$file->copy(IMG_DIR . 'portfolio\\' . $name . '.' . end($ext));
$final_name = $name . "." . end($ext); // File name with extension
}
// If save
if($this->Client->save($this->request->data)) {
$this->Session->setFlash('Client cadastrado com sucesso!', 'admin_flash');
}
}
}
}
In my client model
public function beforeSave($options = array()) {
if($this->data['Client']['file']['name'] != null) {
$this->data['Client']['file'] = $final_name;
}
return parent::beforeSave($options);
}
In Controller
$this->request->data['Client']['final_name'] = $name . "." . end($ext);
In Model
public function beforeSave($options = array()) {
if($this->data['Client']['file']['name'] != null) {
$this->data['Client']['file'] = $this->data['Client']['final_name'];
}
return parent::beforeSave($options);
}
Update for CakePHP3
Pass variable from controller to table beforeSave, afterSave ?
// Examples
// In Controller
$this->Article->save($data, ['passVariable' => 'passedData']);
// in Table
public function beforeSave(Event $event, EntityInterface $entity, ArrayObject $options)
{
if (isset($options['passVariable'])) {
// implement your code
}
}
Read more: https://api.cakephp.org/3.8/class-Cake.ORM.Table.html#_save
But good place to modify data before save like asked in question are:
https://book.cakephp.org/3.0/en/orm/saving-data.html#before-marshal or
https://book.cakephp.org/3.0/en/orm/entities.html#accessors-mutators
I'm trying to use Session component in custom component (CakePHP 2.3) but when I call Session component functions I get: Fatal error: Call to a member function read() on a non-object in ...\app\Controller\Component\CartComponent.php on line 7
My CartComponent looks like that:
<?php
App::uses('Component', 'Controller');
class CartComponent extends Component {
public $components = array('Session');
function hasItems() {
$cart = $this->Session->read('Cart');
return $cart != null && count($cart) > 0;
}
}
?>
And I use it in controller:
<?php
class OrdersController extends AppController {
public $name = 'Orders';
public $components = array('Cart', 'Email');
function beforeFilter() {
parent::beforeFilter();
if ($this->Cart->hasItems()) {
$this->Auth->allow('add_item', 'remove_item', 'cart');
} else {
$this->Auth->allow('add_item', 'remove_item', 'cart', 'make');
}
}
}
?>
For using session inside the custom component I tried with
public $components = array('Session');
and then called it by using
$this->Session->read('Cart');
but I cant able to use it and I start to use
CakeSession::read('Cart')
Now it works Hope it will used for you note I used in cake php version > 2
If you want to use Session in your Component Use-
$test = CakeSession::read('user');
print_r($test);
You should use as bellow
class YourComponent extends Component {
public function initialize(Controller $controller){
$this->controller = $controller;
if (!isset($this->controller->presetVars)) {
$this->controller->presetVars = true;
}
$model = $this->controller->modelClass;
if (!empty($settings['model'])) {
$model = $settings['model'];
}
if ($this->controller->presetVars === true) {
// auto-set the presetVars based on search definitions in model
$this->controller->presetVars = array();
$filterArgs = array();
if (!empty($this->controller->$model->filterArgs)) {
$filterArgs = $this->controller->$model->filterArgs;
}
foreach ($filterArgs as $key => $arg) {
if ($args = $this->_parseFromModel($arg, $key)) {
$this->controller->presetVars[] = $args;
}
}
}
foreach ($this->controller->presetVars as $key => $field) {
if ($field === true) {
if (isset($this->controller->$model->filterArgs[$key])) {
$field = $this->_parseFromModel($this->controller->$model->filterArgs[$key], $key);
} else {
$field = array('type' => 'value');
}
}
if (!isset($field['field'])) {
$field['field'] = $key;
}
$this->controller->presetVars[$key] = $field;
}
/* now you can use Component existing in your Component :) */
public function sayHello(){
$this->controller->Session->setFlash(__('Hello you'));
}
}
I'm searching for a better PDO db connection which I could use in the different classes I have. For example my current code is like this:
core.php
//Connecting to Database
try {
$db = new PDO("mysql:host=localhost;dbname=mydb", "project", "project123");
}
catch(PDOException $e) {
echo $e->getMessage();
}
class Core {
protected $db;
public function __construct(PDO $db) {
$this->db = $db;
}
function redirectTo($page,$mode = 'response',$message = '') {
if($message != '') {
header('Location: '.SITEURL.'/'.$page.'?'.$mode.'='.urlencode($message));
} else {
header('Location: '.SITEURL.'/'.$page);
}
exit();
}
}
And apart from this I have 2 more class: wall.php and ticker.php
class Wall {
protected $db;
public function __construct(PDO $db) {
$this->db = $db;
}
function addComment($uid, $fid, $comment) {
$time = time();
$ip = $_SERVER['REMOTE_ADDR'];
$query = $this->db->prepare('INSERT INTO wall_comments (comment, uid_fk, msg_id_fk, ip, created) VALUES (:comment, :uid, :fid, :ip, :time)');
$query->execute(array(':comment' => $comment, ':uid' => $uid, ':fid' => $fid, ':ip' => $ip, ':time' => $time));
$nofity_msg = "User commented on the post";
$setTicker = Ticker::addTicker($uid,$nofity_msg,'comment');
if($setTicker) {
Core::redirectTo('wall/view-'.$fid.'/','error','Oops, You have already posted it!');
} else {
Core::redirectTo('wall/view-'.$fid.'/','error','Oops, Error Occured');
}
}
}
and ticker.php is:
class Ticker {
protected $db;
public function __construct(PDO $db) {
$this->db = $db;
}
function addTicker($uid,$msg,$type) {
$time = time();
$query = $this->db->prepare('INSERT INTO tickers (uid_fk, message, type, created) VALUES (:uid, :message, :type, :time)');
try {
$query->execute(array(':uid' => $uid, ':message' => $msg, ':type' => $type, ':time' => $time));
return $this->db->lastInsertId();
}
catch(PDOException $e) {
return 0;
}
}
}
Now my problem is that I need to call for the function addComment() and inside that function there is a further call for the function addTicker() present in the class Ticker. This is causing a Db connection problem as there is already an db instance created in the previous class or so.. I can't figure out how to sort this out.
This is the code I'm using in the main index file:
$core = new Core($db);
$ticker = new Ticker($db);
$wall = new Wall($db);
$wall->addComment($uid, $fid, $add_comment); // This statement is not working.. :(
My intention is to have a common main DB connection and further use that connection in other classes. Is there any better way to do it..?
there is already an db instance created in the previous class
this is actually single instance, but copied into 2 variables.
This is causing a Db connection problem
Can you please be a bit more certain about such a problem? What particular problem you have?
