Question

我正在试图弄清楚如何最好地做到这一点，我不认为它应该太难，但我正是这样做的！在我的网站中，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，每个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天内返回网站的成员不会将此计入新条目，而只是与前一个条目相同的另一个提交。同样，如果成员在最后一个输入日期后超过49天返回到站点，则条目号将不会连续但将增加2，表示条目之间的中断。这就是我想出的，允许在正确的时间范围内填写数据的成员之间做出区分 - 希望这一切都有意义！

对于我的代码/设计问题，任何人都可以帮助我在这里改进我的代码以及如何最好地在时间框架中添加检查？这是我的模型，我试图管理条目，以便它返回正确的条目（即一个新的 - 由最后一个增加一个或两个，或者从当前时期增加一个）

任何指针都会非常感激！

//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，您只需比较差异并相应地执行正确的功能。

因此...

 <?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


    }


    ?>
