Cannot search based on multiple id in find query in Cakephp 3 - php

Question

I have two tables category and product. I want to get details of product whose id are passed in conditions array of find query. The problem is when i pass condition as an array, it returns
Cannot convert value to integer
Secondly, if i debug it by passing only one id it returns category record, but it should return product record. Please help to solve my issue.
My code is as follows:
public function display()
{
$ids = array(1,2,3,4,5);
$c_List = $this->Products->Categories->find('all',array('conditions'=>array('Categories.category_id'=>$ids)));
$data = $c_List->toArray();
debug($data);
die();
}
Model - ProductsTable.php
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('products');
$this->setDisplayField('product_id');
$this->setPrimaryKey('product_id');
$this->belongsTo('Products', [
'foreignKey' => 'product_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Categories', [
'foreignKey' => 'category_id',
'joinType' => 'INNER'
]);
}
Model - CategoriesTable.php
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('categories');
$this->setDisplayField('category_id');
$this->setPrimaryKey('category_id');
$this->belongsTo('Categories', [
'foreignKey' => 'category_id',
'joinType' => 'INNER'
]);
}

Answer 1

When you are finding the records based on an array of ids, use IN in the condition clause.
public function display()
{
$ids = array(1,2,3,4,5);
$c_List = $this->Products->Categories->find('all',array('conditions'=>array('Categories.category_id IN'=>$ids)));
$data = $c_List->hydrate(false)->toArray();
pr($data);
die();
}
