The examples in this article describe the CakePHP framework Model Function definition method. I share it with you for your reference, as follows:

In CakePHP, the MVC architecture is clear, but in actual projects, I found that many people still like to stack functions in the Controller, and doing so is also It's not a bad idea, but for a large project with millions of rows, this kind of violation of MVC thinking may temporarily bring convenience to the program structure, but in the long run, it is absolutely undesirable!

We should define certain functions commonly used in the system in the Model, especially pure data processing functions and data query functions:

For example, conditional query like the following in Blog:

/*
*
*  Blog 根据条件得到相应字段结果集
*
* @Param  array  conditions
*      array  fields
* @Return  array
*
*/
function getBlogsByCon($conditions = array(),$fields = null){
  return $this->find('all',array(
      'conditions'=>ife(count($conditions) > 0, am(array('`Blog`.`status` = 1'),$conditions), array('`Blog`.`status` = 1')),
      'fields'=>$fields,
      'order'=>'`Blog`.`created` DESC',
      'page'=>1,
      'recursive'=>0));
}
