array for multiple where_in condition in codeigniter [duplicate] - php

Question

This question already has an answer here:
Codeigniter model with multiple update conditions using manual where statement
(1 answer)
Closed 5 years ago.
$this->db->where('column_field1',$value1);
$this->db->where('column_field2',$value2);
For above two query we can write a single query as:
$arr = array('column_field1'=>'value1', 'columne_field2'=>'value2');
function select($arr){
.. .. ..
... .. . ..
$this->db->where($arr);
}
is there any solution for the where_in query:
function($value1, $value2){
$this->db->where_in('column_field1',$value1);
$this->db->where_in('column_field2',$value2);
}
as I have tried but didn't work:
arr = array('column_field1'=>$arr,'column_field2'=>arr2);
function select_in($arr)
{
$this->db->select('*');
$this->db->from('table');
$this->db->where_in($arr);
$query = $this->db->get();
return $query;
}
I want to combine the where_in condition so that i can store multiple column_field and array for it.
$this->db->where_in($arr);
where $arr contains pair of column_filed and array_of_value:
$arr = $array('column_field'=>$arr_of_value);

Answer 1

function select_in($arr)
{
$this->db->select('*');
$this->db->from('table');
$this->db->where($arr); // change here
$query = $this->db->get();
return $query;
}
If you want multiple where In then you need to write it twice....It's not possible in single statement.
$this->db->where_in('field1',$cond1);
$this->db->where_in('field2' , $cond2);
Note: Where_in is similar to where id IN (1,2,3...)but in your case you are doing multiple where condition.

Answer 2

Creating custom method is a reasonable solution for this, you can either extend database's active record class or write custom function which takes array and call where_in like below
function multiple_where_in($array){
foreach($array as $key => $data){
$this->db->where_in($key, $data);
}
}
And call like below
function select_in($arr)
{
$this->db->select('*');
$this->db->from('your_table');
$this->multiple_where_in($arr); // call local function created above
$query = $this->db->get();
return $query;
}
// create array like below, fieldname and field_values inside array
$arr = array(
'column_field1'=>array('value1','value2'),
'columne_field2'=>array('value2','value3')
);
// call your select method
$this->select_in($arr);

Answer 3

You can try this solution for your problem.
$this->db->select('*');
$this->db->from('table');
if(!empty($cond1) && !empty($cond2)){
$this->db->where("field1 IN (".$cond1.") AND field2 IN (".$cond2.") ",null,false);
}
$query = $this->db->get();
return $query;
I hope this will helps you. Thanks!
