Changing column names

[mlukac89]

Recently i had issue when i was using renaming columns using AS using joined tables because some tables have same column names.
I was getting error undefined index: novi_naziv and search on column header and search input was not working.

$columns = array(
            array('db' => 'c.naziv AS novi_naziv', 'dt' => 1, 'field' => 'novi_naziv')
);

Using same name in fields was causing that i had same output in 2 columns in datatables, so i needed to use AS to change column name for joined tables, this is example for this scenario, you can see on image below also

$columns = array(
            array('db' => 'a.naziv', 'dt' => 1, 'field' => 'naziv'),
            array('db' => 'c.naziv', 'dt' => 2, 'field' => 'naziv')
);

FIX for this, at least it works for me

if (strpos($column['db'], 'AS') !== FALSE) {
    $column['db'] = explode('AS', $column['db'])[0];
}

those changes was made in those functions in SSP class

function order()
function filter()

Actually, that renaming support already exist

You can achieve that by defining the as key in the column array.

Like this

$columns = array(
            array('db' => 'c.naziv', 'dt' => 1, 'field' => 'novi_naziv', 'as' => 'novi_naziv')
);

Well, i reverted back changes to original state of yours class then used AS from yours example.
When try to search in search box then i get error, here is query output and error

SELECT SQL_CALC_FOUND_ROWS b.naziv, b.registarska_oznaka, a.stanje_brojila, a.datum_servisa, a.iznos_racuna, a.slika_racuna, c.naziv AS serviser, a.redovan_servis, a.napomena, a.opis, a.sljedeci_servis_km, a.id 
        FROM servisi_vozila AS a 
        LEFT JOIN vozila AS b ON (b.id = a.id_vozila) 
        LEFT JOIN tvrtke AS c ON (c.id = a.serviser) 
        ORDER BY c.naziv AS serviser ASC LIMIT 0, 10 // note this one is that makes issue "AS serviser"

and when clicked on column to sort then i get this error

SELECT SQL_CALC_FOUND_ROWS b.naziv, b.registarska_oznaka, a.stanje_brojila, a.datum_servisa, a.iznos_racuna, a.slika_racuna, c.naziv AS serviser, a.redovan_servis, a.napomena, a.opis, a.sljedeci_servis_km, a.id 
        FROM servisi_vozila AS a 
        LEFT JOIN vozila AS b ON (b.id = a.id_vozila)

here is how this is produced

public function get_vehicle_service_by_id($vehicle_id)
	{
        $primaryKey = 'id';

        $joinQuery = "FROM {$this->table} AS a LEFT JOIN vozila AS b ON (b.id = a.id_vozila) LEFT JOIN tvrtke AS c ON (c.id = a.serviser)";
        $where = "a.id_vozila = {$vehicle_id}";
        
        $columns = array(
            array(
                'db' => 'a.datum_servisa', 
                'dt' => 0, 
                'field' => 'datum_servisa',
                'formatter' => function($d, $row) {
                    return date('d.m.Y', strtotime($d));
                }
            ),
            array('db' => 'a.iznos_racuna', 'dt' => 1, 'field' => 'iznos_racuna'),
            array(
                'db' => 'a.slika_racuna',
                'dt' => 2,
                'field' => 'slika_racuna',
                'formatter' => function($d, $row) {
                    return $d != null ? '<a href="'.$d.'" target="_blank" rel="noopener noreferrer">Pogledaj račun</a>' : '';
                }
            ),
            array('db' => 'c.naziv', 'dt' => 3, 'field' => 'serviser', 'as' => 'serviser'),
            array(
                'db' => 'a.redovan_servis', 
                'dt' => 4, 
                'field' => 'redovan_servis',
                'formatter' => function($d, $row) {
                    return $d == 1 ? 'Da' : 'Ne';
                }
            ),
            array('db' => 'a.napomena', 'dt' => 5, 'field' => 'napomena'),
            array('db' => 'a.opis', 'dt' => 6, 'field' => 'opis'),
            array('db' => 'a.sljedeci_servis_km', 'dt' => 7, 'field' => 'sljedeci_servis_km'),
            array(
                'db' => 'a.id', 
                'dt' => 8, 
                'field' => 'id',
                'formatter' => function($d, $row) {
                    return '<a href="javascript:void(0);" title="Uredi" onclick="edit_service('.$d.')"><i class="fa fa-pencil icon text-warning"></i></a>&nbsp;&nbsp;&nbsp;&nbsp;
            <a href="javascript:void(0)" title="Izbriši" onclick="delete_service('.$d.')"><i class="fa fa-trash icon text-danger"></i></a>';
                }
             )
        );

        $sql_details = array(
            'user' => $this->db->username,
            'pass' => $this->db->password,
            'db'   => $this->db->database,
            'host' => $this->db->hostname,
            'charset' => 'utf8'
        );
                 
        echo json_encode(
            SSP::simple( $_POST, $sql_details, $this->table, $primaryKey, $columns, $joinQuery, $where)
        );
	}

EDIT:
if i use mine fix in code all is working on both ways

array('db' => 'c.naziv', 'dt' => 3, 'field' => 'serviser', 'as' => 'serviser')

or this

array('db' => 'c.naziv AS serviser', 'dt' => 3, 'field' => 'serviser')
