Hello guys, I am newbie in codeigniter and I am developing a simple site using this framework. Well I am trying to use num_rows to get all records in an array but still no luck.

here's my codes:

Code:

$query_array = $this->db->query('SELECT STATEMENT');
    die($query_array->num_rows());

Is it correct? Is there any simpliest way to achieve this?

Thanks much!

num_rows will just get the number of rows affected not the value it contains

use

Code:

$query_array->result_array();

instead of

Code:

$query_array->num_rows()

to get the desired output you want.

your suggestion did not work.. when I tried

Code:

$query_array = $this->db->query("SQL HERE");
   die($query_array->result_array());

it only displays "Array" word..

Thanks anyway

to test if it really get the values use

Code:

print_r($query_array->result_array());

Yes, lots of records.. My code using num_rows is same as it showed in codeigniter documentation.

The documentation says like this:

Code:

$query = $this->db->query('SELECT * FROM my_table');
   echo $query->num_rows();

and here's my code:

Code:

$query_array = $this->db->query('SELECT STATEMENT');
  die($query_array->num_rows());

do u know what's wrong with my code?

Thanks

try echoing $query->num_rows() and then die() right after.

BTW: num_rows() will be an integer that tells the number of rows your query returned. It's not the actual results.

of course the data will not display because you did not specify the fields that you want to display:
try to display it all using foreach loop

Code:

$query = $this->db->query('SELECT * FROM my_table');

foreach ($query->result_array() as $row)
{
   echo $row['fieldname'];
}
