Hi everybody. Really been enjoying using this class. I'm sure I'll have questions from time to time but this time I thought I'd share a slight modification I made.
I needed to find a way to count records that matched a certain criteria. SELECT COUNT...WHERE... sort of thing.
$this->users->where('email',$email_str)->count(); would have worked perfectly well but I have this paranoid feeling that as soon as you start chaining where's to your query your controller begins to look a bit like a model.
I wanted something a bit more controller friendly so I created a dynamic function similar to the find_by_fieldname function, called find_count_by_fieldname so now my call ends up looking like $this->users->find_count_by_email($email_str); Not a whole lot different I know, but somehow it just sits a bit better with me having something like that in the controller.
Anyway here are the changes I made. I was using a ChromeIce's development version.
Code:
function __call ($method, $args)
{
$watch = array(
'find_by_',
'find_all_by_',
'join_',
'find_count_by_',
'count_',
'sum_',
'average_',
'concatenate_',
'find_related_',
'fetch_related_'
);
[.....]
and just below the _find_by function I added
Code:
/**
* _find_count_by
*
* Count records in table where condition is met.
*
* There are some special search terms that you can use for particular searches:
* IS_NULL to find null or empty fields NOT_NULL to find fields that aren't
* empty or null
*
*
* @access private
* @param string
* @param array
* @return object
*/
function _find_count_by ($field, $args)
{
$field = $this->_table . '.' . $field;
switch ( $args[0] )
{
case IS_NULL:
$this->where($field . IS_NULL);
break;
case NOT_NULL:
$this->where($field . NOT_NULL);
break;
default:
$this->where($field, $args[0]);
}
return $this->count(null,( isset($args[1]) ) ? $args[1] : null, ( isset($args[2]) ) ? $args[2] : null );
}
