PHP/OOP 帮助 - 逻辑和设计问题

Question

我正在兜圈子，试图找出如何最好地做到这一点，我认为这应该不会太难，但我正在这样做！在我的站点中，每次成员提供一些数据时，我都会将其存储在该成员的条目中。这个想法是，每月连续提交数据的成员将在某个阶段获得奖励。但是有一些参数：在上次访问后 21 天内返回站点的成员不会将其视为新条目，而只是在与前一个条目相同的条目期间再次提交。同样，如果会员在最后一个条目日期后超过 49 天返回网站，则条目​​编号将不是连续的，而是将增加 2，显示条目之间的中断。这就是我想出的方法，以便区分在正确时间范围内填写数据的成员 - 希望这一切都有意义！

对于我的代码/设计问题，谁能帮我在这里改进我​​的代码以及如何最好地添加时间框架检查？这是我的模型，我正在尝试管理条目，以便它返回正确的条目（即一个新条目 - 将最后一个增加一或两个，或者当前期间已经存在的条目） .

任何指针将不胜感激！

//example call from a controller after successful form submission - $this->entry is then passed around for use within that session
$this->entry = $this->pet->update_entry('pet/profile/2');


public function update_entry($stage = NULL)
{
    //get last number entered for this pet
    $last_entry = $this->last_entry();

    //if part one, pet profile is calling the update (passing the next stage as a param)
    if ($stage === 'pet/profile/2')
    {
        //only at this stage do we ever create a new entry
        $entry = ORM::factory('data_entry');

        //if no previous sessions, start from 1
        if ($last_entry === FALSE)
            $num = 1; 
        //here we need to check the time period elapsed since the last submission, still to be ironed out   
        //for now just increment each time, but this may change 
        else
            $num = $last_entry->number + 1;

        //save the rest of the data for a new entry
        $entry->number = $num;
        $entry->initiated = time();
        $entry->updated = time();
        $entry->last_category_reached = $stage;
        $entry->pet_id = $this->id;
        $entry->save();
    }
    elseif ($stage !== NULL)
    {
        //echo $stage; correctly prints out stage
        //this must be a continuation of a form, not the beginning of a new one
        //timeframe checks to be added here
        //just update the stage reached and save
        $last_entry->last_category_reached = $stage;
        $last_entry->updated = time();
        $last_entry->save();
        //assign to $entry for return
        $entry = $last_entry;
    }

    return $entry;
}

/**
 * 
 * Returns the the last data entry session
 */
public function last_entry()
{
        return $this
                    ->limit(1)
                    ->data_entries
                    ->current();

为什么不编写一个使用时间戳计算时差的函数。

然后，您将简单地比较差异并相应地执行正确的功能。

所以...

 <?php
        class time_checker{
         function difference($last_entry){

        $now = time();
        $difference = $now - $last_entry;

        return difference;

        }

    }

    //Let's use the class just before the entry is stored

    $day = 24 * 60 * 60; //Number of seconds in a day because we are using timestamps
    $last_entry = get_last_entry($user_id);// Have a function that gets the last entry
    $time_check = new time_checker;
    $time_since_last_entry = $time_check->difference($last_entry);

    $period_1 = 21 * $day; //21 day period
    $period_2 = 49 * $day; //49 day period
    if($time_since_last_entry < $period_1 ){

    //This is what we'll do if there have been less than 21 days since last entry


    }

    if($time_since_last_entry > $period_2 ){

    //This is what we'll do if there have been more than 49 days since last entry


    }


    ?>
