Question

我正在使用phalcon-2.1.0。我只是为我的博客存档创建一个日历。我想从数据库中检索与日期匹配的数据。我的代码只检索一个帖子，这是我在db中的最后一篇文章。我不了解如何查询循环以检查日期相关数据。我需要检索与用户点击日期相关的帖子。

    foreach ($bloger as $blog) {
       $date = date('Y-m-d', strtotime($blog->datetime));

           $postedDays[] = $date;

    $this->view->setvar('dates', $postedDays);

public function archivesAction($date)
{
    $archs = Blogs::find(["datetime LIKE :key:","bind"=>["key"=>'%'.$date.'%']]);        
    $this->view->setvar('dates', $archs);
    $this->view->pick('blog/archive');
}

Answer 1

您的archivesAction会使用您未使用的参数$date。

您基本上是在查询所有博客并循环浏览它们。在循环时，您可以为$times，$dater和$timer分配值。在foreach结束后，这些值将包含您上次博客记录的日期。

$get = Blogs::find();

foreach($get as $d)
{
    $times = explode(' ', $d->datetime);
    $dater = $times[0];
    $timer = $times[1];
}

$archs = Blogs::find(["datetime LIKE :key:","bind"=>["key"=>'%'.$dater.'%']]);

您应该做的是从您的操作archivesAction($date)的参数中获取日期。用这一行替换上面的代码行：

// changed variable $dater to $date
$archs = Blogs::find(["datetime LIKE :key:", "bind" => ["key"=> '%' . $date . '%']]);

更新

要让您的月份始终输出2个字符，您可以执行此操作：

<?php prev_month = str_pad($prev_month, 2, '0', STR_PAD_LEFT); ?>
<a href="blog?month=<?php echo($prev_month.'&amp;year='.$prev_year);?>">&lsaquo;</a>

检查str_pad documentation以获取更多相关信息。

更新2

要仅突出显示数据库中包含帖子的日历日，您可以执行以下操作：

[控制器]

$blogs = Blogs::find();
$uniqueDays = [];

foreach ($blogs as $blog) {
   $date = date('Y-m-d', strtotime($blog->datetime));

   if (!in_array($date, $uniqueDays)) {
       $uniqueDays[] = $date;
   }
}

$this->view->setVar('databaseDates', $uniqueDays');

[图]

<?php
if (in_array($year.'-'.$month.'-'.$startdate, $databaseDates) {
   // date is found in the database
   // highlight date
}
