How do I do in CI ?

Are you referring to the Active Record class? If so, you can pass in FALSE as the second parameter to $this->db->select() to prevent it from escaping the select statement.

Sorry, I am not able to solve the problem. Can you kindly explain with an example ?

I want to count a specific id, but display all the records pertaining to some condition.


Thanks in advance

Please paste what you have so far, so I can hopefully give you an example that will work.

f you execute the sql immediately after the query you should be able to return the total number of found rows even while a limit/offset is present

Code:

SELECT FOUND_ROWS() AS `FoundRows`;

then just access it like any other value from the database

Why would you issue another request to the database server and wait for a response when mysql_num_rows() does the same thing? or num_rows() within CodeIgniter's ActiveRecord library.

To the OP:

Code:

function get_all() {
  $this->db->select('title, filename, COUNT(*) AS total', FALSE);
  $query = $this->db->get('files');
  if ($query->num_rows() > 0) {
    return $result;
  }
  return FALSE;

Code:

$files = $this->model->get_all();
echo $files->total;

because like I said if you put a limit on the sql the count(*) will be a count of the resultset not of the possible number of results

EDIT:
I just tested it on MySQL server and yes the count(*) tagged onto the end of the query works just as well and returns number of records that match the where clause but not impeded by the limit

If you put a limit on the SQL, num_rows() is still going to return the same thing as FOUND_ROWS().
