I am getting all result zero (0) on database.
Try checking the affected_rows if it is >= 1
public function insert($table, $data){
$this->db->insert($table, $data);
return $this->db->affected_rows() >= 1 ? TRUE : FALSE;
}
Enable profiler in your controller.
eg:
$this->output->enable_profiler(TRUE);
See if your query is executed and if it's correct...

I'm currently creating API for multiple inputs using laravel. The data will be stored into two tables : Order and Detail_Order. One order can have many detail orders.
But now, the data only stored into Order table, and got an error: ErrorException: Invalid argument supplied for foreach() in file. Does anyone know how? Thank you.
Here's my code :
public function createDetail($total_passenger, $id_trip, $id_users, Request $request){
$trip = Trip::where(['id_trip' => $id_trip])->get();
$seat = $request->id_seat;
if(Detail_Order::where(['id_trip' => $id_trip, 'id_seat' => $seat])
->where('status', '!=', 5)
->exists()) {
return $this->error("Seat has been booked");
}else{
$order = new Order();
$order_select = Order::select('id_order');
$order_count = $order_select->count();
if ($order_count === 0) {
$order->id_order = 'P1';
}else{
$lastrow=$order_select->orderBy('created_at','desc')->first();
$lastrow_id = explode('P', $lastrow->id_order);
$new_id = $lastrow_id[1]+1;
$order->id_order = 'P'.$new_id;
}
$order->id_trip = $id_trip;
$order->id_users = $id_users;
$order->date_order = date('Y-m-d H:i:s');
$order->id_users_operator = 'O4';
$order->save();
foreach($request->passenger_name as $key => $value){
Detail_Order::create([
'id_trip' => $order->id_trip,
'id_seat' => $request->id_seat[$key],
'id_order' => $order->id_order,
'passenger_name' => $request->passenger_name[$key],
'gender' => $request->gender[$key],
'departure' => $request->departure[$key],
'destination' => $request->destination[$key],
'phone' => $request->phone[$key],
'status' => 1
]);
}
return response()->json([
'status' => true,
'message' => "Successfully saved data",
'data' => $order
]);
}
I am trying to insert $product, $pric and $user to database table cart. Following is the function that I have created in SiteController.php.
public function actionCartadd($id)
{
$product = Additem::find()
->select('product')
->where(['id' => $id])
->one();
$pric = Additem::find()
->select('price')
->where(['id' => $id])
->one();
$user = Yii::$app->user->identity->username;
$connection = Yii::$app->getDb();
$result = Yii::$app->db->createCommand()
->insert('cart', [
'product' => '$product',
'price' => '$pric',
'user' => '$user',
])->execute();
if ($result)
return $this->render('custstore');
}
However, this end up in error. Can anyone suggest any fix
Try this following code
$result = Yii::$app->db->createCommand()->insert('cart', [
'product' => $product->product,
'price' => $pric->price,
'user' => $user
])->execute();
Look at this fragment:
'product' => '$product',
'price' => '$pric',
'user' => '$user',
Use double quotes in values or just variables without quotes
Also, better way to fetch product and price:
$productItem = Additem::findOne($id);
if ($productItem instanceof Additem) {
$product = $productItem->product;
$pric = $productItem->price;
}
I have this problem: I need to get data from database and filter them. but then I need to use custom php function to filter those filtered results using data from it.
Clasic search function in ActiveDataProvider
public function search($params) {
$query = Passenger::find();
// add conditions that should always apply here
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
// I guess my function would go like here
Passenger::filterResultsEvenMore($dataProvider);
$this->load($params);
if (!$this->validate()) {
// uncomment the following line if you do not want to return any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([
'passenger_id' => $this->passenger_id,
// ...
'version' => $this->version,
'status' => $this->status,
]);
return $dataProvider;
}
So my question is how to work with results of dataProvider because if I vardump the variable it looks like this and no actual data there.
yii\data\ActiveDataProvider Object
(
[query] => common\models\PassengerQuery Object

[sql] =>

)
UPDATE
I need to use function like this for each record:
if (myFunction(table_column_1, table_column_2)) {
result_is_ok_return_it
} else {
do_not_return_this_record
}
Why do you don't add your additional filters to query object used in DataProvider?
You can parse your conditions to $query->andFilterWhere(). If you need custom function for it just modify $dataProvider->query object inside function. After execute query in data provider you can only filter results by manually filter array of models stored in $dataProvider->models
To get result use models property or getModels()
For example,
$dataProvider->models;
OR
$dataProvider->getModels();
I think I came across a solution, (looks like it is working)
http://www.yiiframework.com/doc-2.0/yii-data-basedataprovider.html#setModels()-detail
After I do all my usual search stuff as described in question at beginning, I would do something like this using setModels() function
class PassengerSearch extends Passenger
public $status; // virtual attribute not present in database table
public function rules()
{
return [
// ... some other rules
[['status'], 'safe'],
];
}
// ...
$filtered_models = [];
$filter_models = false; // if you only want to filter if there is some value
foreach ($dataProvider->models as $model) {
// if ($model->status == 1) // example
if (!empty($this->status) && $model->status == $this->status) { // better approach, using virtual attribute $status
$filter_models = true;
$filtered_models[] = $model;
}
}
if ($filter_models)
$dataProvider->setModels($filtered_models);
return $dataProvider;
}
In a controller I have the following code:
public function actionView($id)
{
$query = new Query;
$query->select('*')
->from('table_1 t1')
->innerJoin('table_2 t2', 't2.t1_id = t1.id')
->innerJoin('table_3 t3', 't2.t3_id = t3.id')
->innerJoin('table_4 t4', 't3.t4_id = t4.id')
->andWhere('t1.id = ' . $id);
$rows = $query->all();
return $this->render('view', [
'model' => $this->findModel($id),
'rows' => $rows,
]);
}
See the db schema: https://github.com/AntoninSlejska/yii-test/blob/master/example/sql/example-schema.png
In the view view.php are displayed data from tables_2-4, which are related to table_1:
foreach($rows as $row) {
echo $row['t2_field_1'];
echo $row['t2_field_2'];
...
}
See: Yii2 innerJoin()
and: http://www.yiiframework.com/doc-2.0/yii-db-query.html
It works, but I'm not sure, if it is the most correct Yii2's way.
I tried to define the relations in the model TableOne:
public function getTableTwoRecords()
{
return $this->hasMany(TableTwo::className(), ['t1_id' => 'id']);
}
public function getTableThreeRecords()
{
return $this->hasMany(TableThree::className(), ['id' => 't3_id'])
->via('tableTwoRecords');
}
public function getTableFourRecords()
{
return $this->hasMany(TableFour::className(), ['id' => 't4_id'])
->via('tableThreeRecords');
}
and then to join the records in the controller TableOneController:
$records = TableOne::find()
->innerJoinWith(['tableTwoRecords'])
->innerJoinWith(['tableThreeRecords'])
->innerJoinWith(['tableFourRecords'])
->all();
but it doesn't work. If I join only the first three tables, then it works. If I add the fourth table, then I receive the following error message: "Getting unknown property: frontend\models\TableOne::t3_id"
If I change the function getTableFourRecords() in this way:
public function getTableFourRecords()
{
return $this->hasOne(TableThree::className(), ['t4_id' => 'id']);
}
then I receive this error message: "SQLSTATE[42S22]: Column not found: 1054 Unknown column 'table_4.t4_id' in 'on clause'
The SQL being executed was: SELECT table_1.* FROM table_1 INNER JOIN table_2 ON table_1.id = table_2.t1_id INNER JOIN table_3 ON table_2.t3_id = table_3.id INNER JOIN table_4 ON table_1.id = table_4.t4_id"
You should have to define key value pair in the relation eg:
class Customer extends ActiveRecord
{
public function getOrders()
{
return $this->hasMany(Order::className(), ['customer_id' => 'id']); // Always KEY => VALUE pair this relation relate to hasMany relation
}
}
class Order extends ActiveRecord
{
public function getCustomer()
{
return $this->hasOne(Customer::className(), ['id' => 'customer_id']);
// Always KEY => VALUE pair this relation relate to hasOne relation
}
}
Now in your forth relation use:
public function getTableFourRecords()
{
return $this->hasOne(TableThree::className(), ['id' => 't4_id']);
}
You can read more on ActiveRecord here
Based on the answer of softark the simplest solution can look like this:
Model TableOne:
public function getTableTwoRecords()
{
return $this->hasMany(TableTwo::className(), ['t1_id' => 'id']);
}
Model TableTwo:
public function getTableThreeRecord()
{
return $this->hasOne(TableThree::className(), ['id' => 't3_id']);
}
Model TableThree:
public function getTableFourRecord()
{
return $this->hasOne(TableFour::className(), ['id' => 't4_id']);
}
Controller TableOneController:
public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),
]);
}
The view table-one/view.php:
foreach ($model->tableTwoRecords as $record) {
echo ' Table 2 >> ';
echo ' ID: ' . $record->id;
echo ' T1 ID: ' . $record->t1_id;
echo ' T3 ID: ' . $record->t3_id;
echo ' Table 3 >> ';
echo ' ID: ' . $record->tableThreeRecord->id;
echo ' T4 ID: ' . $record->tableThreeRecord->t4_id;
echo ' Table 4 >> ';
echo ' ID: ' . $record->tableThreeRecord->tableFourRecord->id;
echo ' <br>';
}
A solution based on the GridView is also possible.
Model TableTwo:
public function getTableOneRecord()
{
return $this->hasOne(TableOne::className(), ['id' => 't1_id']);
}
public function getTableThreeRecord()
{
return $this->hasOne(TableThree::className(), ['id' => 't3_id']);
}
public function getTableFourRecord()
{
return $this->hasOne(TableFour::className(), ['id' => 't4_id'])
->via('tableThreeRecord');
}
The function actionView in TableOneController, which was generated with Gii for the model TableTwo was edited:
use app\models\TableTwo;
use app\models\TableTwoSearch;
...
public function actionView($id)
{
$searchModel = new TableTwoSearch([
't1_id' => $id, // the data have to be filtered by the id of the displayed record
]);
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('view', [
'model' => $this->findModel($id),
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
and also the views/table-one/view.php:
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
'id',
't1_id',
'tableOneRecord.id',
't3_id',
'tableThreeRecord.id',
'tableThreeRecord.t4_id',
'tableFourRecord.id',
],
]);
See the code on Github.
I'm new to cakephp2 and mysql and need some help.
I want to get the data from yesterday and daybefore yesterday date from the same Model in cakephp2,
However the conditions will be different so I am trying to get the data by making two different methods that contains the find() with different conditions. ,however,I'ts not working. Here is the sample below ↓
This method getYesterday() will return the data as a array but I want to add a condition
that will check if the pageview count is not 0, how will I do that ?
public function getYesterday() {
$yes = array();
$dt = date('Y-m-d', strtotime('-1 day'));
// $dy = date('Y-m-d', strtotime('-2 day'));
$yesterday = $this->PvLog->find('all', array(
'fields' => array('dt', 'params', 'count(params) as yesterday_pv'),
'conditions' => array('dt' => "2014/09/26", 'is_crawler' => 0,'count(page_view)>'=>0),
'group' => array('params'),
'order' => array('count(params)' => 'DESC'),
));
foreach ($yesterday as $y) {
$yes[] = $y;
//$i++;
}
return $yes;
}
The function below will get the data from daybefore yesterday
public function getDBY() {
$dayyes = array();
$dt = date('Y-m-d', strtotime('-2 day'));
$daybefore = $this->PvLog->find('all', array(
'fields' => array('dt', 'params', 'count(params) as daybefore_pv'),
'conditions' => array('dt' => "{$dt}", 'is_crawler' => 0),
'group' => array('params'),
'order' => array('count(params)' => 'DESC'),
));
foreach ($daybefore as $dby) {
$dayyes[] = $dby;
//$i++;
}
return $dayyes;
}
The probelem is I'm not sure about this way, Is there a better solution that you can get the different result with different conditions in mysql cakephp2 ? The main thing I want to do Is to get the yesterdays data and daybefore yesterdays data from the same model but I'm not sure how I can do this, I've checked cakes documents but cant find the solution. Sorry for my broken English.
