How do query with a OR and AND operator in CI? - php

Question

I try to make query in Codeigniter via Active Records:
if (isset($data['where']['and'])) {
$this->db->where($data['where']['and']);
}
if (isset($data['where']['or'])) {
$this->db->or_where_in('idSpec', $data['where']['or']);
}
I want to get:
WHERE name = 1 AND (idSpec = 2 OR idSpec = 3 OR idSpec = 4);
But now I get:
WHERE name = 1 OR idSpec = 2 OR idSpec = 3 OR idSpec = 4;

Answer 1

Use below code.
if (isset($data['where']['and'])) {
$this->db->where($data['where']['and']);
}
if (isset($data['where']['or'])) {
$this->db->where("(idSpec = 2 OR idSpec = 3 OR idSpec = 4;)", NULL, FALSE);
}

I assume your $data['where']['or'] contains some ids.
This may help you.
if (isset($data['where']['or']))
{
$or_conditions='(idSpec ='.implode(' OR idSpec = ',$data['where']['or']).')';
$this->db->where($or_conditions);//if this produce error use bellow one
//$this->db->where($or_conditions,'',false);
}

This is the basic method to select data from database I'm using well for a long time..
/**
* Le wild function to make a life better.
* Doing abrakadabra
*
* #param $table
* #param bool $selector
* #param string $order
* #param bool $start
* #param bool $limit
* #param $return
*
* #return mixed
*/
public function _getCustomTableData($table, $selector = FALSE, $order = 'id DESC', $start = FALSE, $limit = FALSE, $return = FALSE, $group_by = FALSE)
{
$query = $return ? $this->db->select($return) : $this->db->select('*');
if ( $selector ) {
if ( isset($selector['mixed_selection']) && $selector['mixed_selection'] == TRUE ) {
$query = $this->db->where($selector['mixed_selection']);
} else {
foreach ( $selector as $select_array ):
$query = $this->db->where($select_array);
endforeach;
}
}
if ( $group_by ) {
$query = $this->db->group_by($group_by);
}
$query = $this->db->order_by($order);
if ( $start && $limit ) {
$query = $this->db->limit($limit, $start);
}
if ( ! $start && $limit ) {
$query = $this->db->limit($limit);
}
// proceed
$query = $this->db->get($table);
if ( $limit == TRUE && $limit == 1 ) {
$query = $query->row_array();
if ( $return ) {
return $query[$return];
} else {
return $query;
}
} else {
$query = $query->result_array();
return $query;
}
}
and query looks like:
$this->_getCustomTableData('table', array(array('selector' => '1', 'time >=' => time())), 'id DESC', FALSE, 1, 'id');
it's like:
SELECT 'id' FROM `table` WHERE `selector` = 1 AND `time` >= 1472582... ORDER BY id DESC LIMIT 1
or you can use "mixed selection"
$this->_getCustomTableData('table', array('mixed_selection' => 'selector = 1 AND time >= 1472582...'), 'id DESC', FALSE, 1, 'id');
and the result will be the same. I have wrote this method when I was beginner with CI and it helped me a lot :)
