Question

PHP/MySQL (CodeIgniter)

I would like to add new interest_keywords in the exist database value.

here is my code

$query = 'SELECT u_interest_keyword FROM '.T_USER_ACCOUNT.' WHERE u_id = "'.$u_id.'"';
$result = $this->db->query($query);

$result_keyword = $result.','.$personal_keyword;

$query = 'UPDATE '.T_USER_ACCOUNT.' SET u_interest_keyword = "'.$result_keyword.'" WHERE u_id = "'.$u_id.'"';
$this->db->query($query);

It just replaces a new keyword in the database.

Can you tell me why it doesn’t work?

Answer 1

$this->db->query returns object when read type queries are run.

So, you have to do something like this after $result = $this->db->query($query);

$result_row = $result->row();

Then Rectify this:

$result_keyword = $result_row->u_interest_keyword. ',' .$personal_keyword;
