codeigniter activerecord where clause issue with own clauses manually

Question

I'm not sure it's right or wrong but I want to use below where clauses. I'm following Codeigniter manual (chapter Active Record Class , section $this->db->where(); , point 4) Custom string ).

1. $condition = uid = '4' AND id = '1';
2. My Controller

$fields = "id";
$condition = "";
if($condition) { 
  $condition.=" AND ";
}
if($json_decoded->userId) { 
  if($condition) { 
    $condition.=" AND ";
  }
  $condition.=" uid = '".$json_decoded->userId."'";
}
if($json_decoded->listId) { 
  if($condition) { 
    $condition.=" AND ";
  }
  $condition.=" id = '".$json_decoded->listId."'";
}
 $checkExist = $this->mdl_details->getDetailByIdandUid($fields,$condition);

3. My Models function

$this->db->select($fields);

$this->db->from(TBL_DETAILS);

if(!empty($condition)) { 
  $this->db->where($condition);
}

$query = $this->db->get()->row();
echo $this->db->last_query(); die;
return $query;

It shows me error as bellow

Error Number: 1054

Unknown column ' uid = '4' AND id = '1'' in 'where clause'

SELECT `id` FROM (`guide`) WHERE ` uid = '4' AND id = '1'

How can I get rid of this backtick (`) character in the query?

Answer 1

Pass 'FALSE' as third parameter in $this->db->where(), then codeigniter will not add backticks.

$this->db->where('MATCH (field) AGAINST ("value")', NULL, FALSE);

In your case

$this->db->where($condition, NULL, FALSE);
