Is there a way that I can count the total data that i have? example is that, I have a student table and in a student table there is a student_gender.
The thing is I want to count all the female gender that I have, and if possible i want to post it in a page thanks
You could use this - http://www.yiiframework.com/doc/api/1.1/CActiveRecord#countByAttributes-detail.
$countFemale = Student::model()->countByAttributes(array('student_gender' => 'female'));
This code assumes that Student is an Active Record class for your student db table.
