morning,
I would like to multiple update data to data base using explode expression
here my controller :
$id = explode(' ',$this->post('id'));
$respond = $this->model->update($id,$data);
my model :
public function update($id=null,$data=null)
{
$this->db->where('id', $id);
$this->db->update($this->table, $data);
return true;
}
When your ID get multple data that time try this...
public function update($id=null,$data=null)
{
for($i=0;$i<count($id);$i++) {
$this->db->where('id', $id[$i]);
$this->db->update($this->table, $data);
}
return true;
}

Morning guys,
I would like to update multiple row using explode function and where in for code igniter, but the problem is, all rows all updated.
here is my controller :
$ids = explode(',', $this->post('id'));
$this->chatmod->update(array('id'=>$ids),$data);
my model :
public function update($ids=null,$data=null)
{
$this->db->where_in($ids);
$this->db->update($this->table, $data);
return true;
}
For updating using column id you need to pass the column name in the where_in function like $this->db->where_in("id",$idarray);
For your code Try the below code:
public function update($ids=null,$data=null)
{
$this->db->where_in('id',$ids);////Pass the column name of the database as first argument.
$this->db->update($this->table, $data);
return true;
}
The where_in query should be supplied with target column, like :
$ids = explode(',', $this->post('id'));
$this->chatmod->update($ids,$data);
public function update($ids=null,$data=null)
{
$this->db->where_in('id', $ids);
$this->db->update($this->table, $data);
return true;
}
It's been several days since I've been blocking to persist items from an order into session to database.
I stock articles in session in an array and I do not know how to persist the array. I try to convert the array into an object, I can not. This is my service:
public function addArticle($id)
{
$sessionCart = $this->session;
$article = $this->doctrine->getRepository('AppBundle:Article')->find($id);
$cart = $sessionCart->get('cart');
$cart[] = $article;
$sessionCart->set('cart', $cart);
// use later for delivery
$sessionCart->get('commande');
return $sessionCart;
}
public function panier()
{
$articles = $this->session->get('cart');
return $articles;
}
public function delivery(Request $request)
{
$commande = new Commande();
$articles = $this->session->get('cart');
$form = $this->form->create(CommandeType::class, $commande);
if ($request->isMethod('POST') && $form->handleRequest($request)->isValid())
{
$data = $form->getData();
$this->session->set('commande', $data);
$response = new RedirectResponse('payment');
$response->send();
}
return [$form, $articles];
}
public function payment(Request $request)
{
$articles = $this->session->get('cart');
$commande = $this->session->get('commande');
if ($request->isMethod('POST')) {
$em = $this->doctrine;
$em->persist($articles);
$em->persist($commande);
$em->flush();
}
return[$articles, $commande];
}
Error : "EntityManager#persist() expects parameter 1 to be an entity object, array given."
The order is persisted but not the items.
Thanks
I can't understand these two lines
$cart = $sessionCart->get('cart');
$cart[] = $article;
$sessionCart->set('cart', $cart);
$cart is an array and should be an entity isn't it ?
The persist is waiting for an entity,
maybe you can persist in a foreach loop:
foreach($articles as $article){
$em->persist($article);
}
or use a doctrineCollection instead of an array
Im trying to save specific field from a record into a session, for my user-role. The problem here is i cannot take any other field except nama.
controller/verify_login
public function index(){
$this->load->model('verify_login_model');
$username = $this->input->post('username');
$password = $this->input->post('password');
$result = $this->verify_login_model->verify($username, $password);
if($result == $username) {
$name = $this->verify_login_model->getinfo($username);
$this->session->set_userdata('logged_in', TRUE);
$this->session->set_userdata('username', $username);
$this->session->set_userdata('name', $name);
$this->load->view('home_view');
} else {
redirect('login');
}
model/verify_login_model
function verify($username, $password){
$this->db->select('username', 'password');
$this->db->from('tb_user');
$this->db->where('username', $username);
$this->db->where('password', MD5($password));
$this->db->limit(1);
$query = $this->db->get();
if($query->num_rows()==1) {
return $username;
} else {
return false;
}
}
function getinfo($username) {
$this->db->select('nama', 'username');
$this->db->from('tb_userInfo');
$this->db->where('username', $username);
$this->db->limit(1);
$query = $this->db->get();
if($query->num_rows()==1) {
$result = $query->row();
return $result->nama;
} else {
return false;
}
}
view
<?php echo $this->session->userdata['name']?>
the var_dump($result) : object(stdClass)#22 (1) { ["nama"]=> string(4) "test" }
if i change the return $result->nama; to $result->username; i get error : Undefined property: stdClass::$username even tho im sure 200% there's username field in the table, and tried the query directly.
There's an error in your select statement, it must be
$this->db->select('nama,username');
You are separating each column, and that's not correct, all of the columns go in one string, that's why it tells you its undefined since the only column you are sending is nama and you're sending username as the second parameter for the select.

I have a specific task to connect CakePHP web application to a remote restful server . I create a datasource, read method works great, but the api after save data return an array of processed data.
Looking for a way to return the data array and use in controller.
My Controller code
public function admin_generate()
{
$data = $this->request->data;
$data['path'] = 'special/generate';
$this->Tool->create();
if($this->Tool->save($data)){
// handle response ????
}
$this->set('data',$data);
$this->set('_serialize','data');
}
In datasource file
public function create(Model $model, $fields = null, $values = null)
{
$data = array_combine($fields, $values);
$api = $this->config['api_path'].$data['path'].'?auth_key='.$this->config['auth_key'];
$json = $this->Http->post($api, $data);
$response = json_decode($json, true);
if (is_null($response)) {
$error = json_last_error();
throw new CakeException($error);
}
return $response; // ??????
}
Can someone show me the correct way to use the api response data in the controller?
I found a solution, a few minutes after a post question. This can help one of you.
datasource
....
if (is_null($response)) {
$error = json_last_error();
throw new CakeException($error);
}
// SOLUTION
$model -> code = $response['code'];
$model -> key = $response['key'];
$model -> code_id = $response['code_id'];
return true;
.....
in controller
.....
if($this->Tool->save($data)){
unset($data['path']);
$data['code'] = $this->Tool->code;
$data['key'] = $this->Tool->key;
$data['code_id'] = $this->Tool->code_id;
}
.....
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?
