/*** loop over the results ***/
$chklogin_val = $result->rowCount();

Answer 1

Shouldn't your query be:

SELECT services.id, services.title, services.link, services.link_open, add_services.aid, add_services.tittle
FROM   services
LEFT JOIN add_services ON  AND services.g1 = add_services.g1 AND 
WHERE services.status='A' and add_services.type='E' and services.g1 = 'G1'

Answer 2

You can use this query....

SELECT services.id, services.title, services.link, services.link_open, add_services.aid, add_services.tittle FROM services LEFT JOIN add_services ON services.g1 = add_services.g1 where services.status='A' and add_services.type='E'
