Question

我正在尝试根据一小时显示一些内容。这小时来自DB作为字符串字段。如果当前时间与DB匹配或传递时间，则应显示某个内容，否则为默认内容

到目前为止我尝试了什么：

       $time    = strtotime($p_objetct->getHour());

      //we check if  this has already passed to 
      //retrieve corresponding content else we display default content
      if ($time >= date("h:i:sa")) {
            echo 'time to display new content !';
      }else{
            echo 'display content default';
      }

此代码效果不佳，因为您可以猜测，因为如果我想在20:00:00显示新内容，当前时间是08:00:00时，第1个条件为真。

我也试过了

$time      = strtotime(p_objetct->getHour());
$selection = floor((date('G',$time) / 2));
switch ($selection) {
case 0:
   echo 'time between 0-2!';
   break;
case 1:
   echo 'time between 2-4!';
   break;
case 2:
  echo 'time between 4-6!';
  break;
case 3:
  echo 'time between 6-8!';
  break;
case 4:
   echo 'time between 8-10!';
   break;
case 5:
   echo 'time between 10-12!';
   break;
case 6:
  echo 'time between 12-14!';
  break;
case 7:
  echo 'time between 14-16!';
  break;
case 8:
  echo 'time between 16-18!';
  break;
case 9:
  echo 'time between 18-20!';
  break;
case 10:
  echo 'time between 20-22!';
  break;
case 11:
  echo 'time between 22-24!';
  break;
}

但这不是一个好方法，因为我无法猜测在哪种情况下来自DB的时间将是......

欢迎任何想法！

修改：

我有2个内容（新的和默认的）。新内容应该从DB到00:00:00的时间显示，然后它应该是默认的

Answer 1

如果您只使用@app.route('/temperatuur', methods=['GET','POST',]) def temperatuur(): zipcode = request.form['zip'] r = requests.get('http://api.openweathermap.org/data/2.5/weather?zip='+zipcode+',be&APPID=84c7d83bae2f2396ebd3a4a48dfdd057') json_object = r.json() weer = json_object['weather',[1]] temp_k = int(json_object['main']['temp']) temp_c = (temp_k - 273) plaats = str(json_object['name']) return render_template('temperatuur.html', temperatuur=temp_c, plaats = plaats, weer = weer)方法获得24小时格式的小时，则可以将其与$p_objetct->getHour()进行比较。

如果你看完完全匹配，你可以使用：

date('H');

如果您需要它作为下限时间随意使用并更改此代码段：

<?php
$hourToCheck = $p_objetct->getHour();
$currentHour = date('H'); // As of PHP manual "H" returns the hour in 24h format

$contentToDisplay = "What ever you wanna display as default.";
if ($hourToCheck === $currentHour) {
    $contentToDisplay = "Your matching content.";
}

Answer 2

您可以尝试使用基于时间的名称设置变量，使用该名称匹配现有文件并使用php进行匹配。像这样：

<?php
    $time      = date('H',time());
    $name_of_content_to_require = false;
    switch ($time) {
    case 0:
       $name_of_content_to_require = '0-2';
       break;
    case 1:
       $name_of_content_to_require = '2-4';
       break;
    case 2:
      $name_of_content_to_require = '4-6';
      break;
    case 3:
      $name_of_content_to_require = '6-8';
      break;
    case 4:
       $name_of_content_to_require = '8-10';
       break;
    case 5:
       $name_of_content_to_require = '10-12';
       break;
    case 6:
      $name_of_content_to_require = '12-14';
      break;
    case 7:
      $name_of_content_to_require = '14-16';
      break;
    case 8:
      $name_of_content_to_require = '16-18';
      break;
    case 9:
      $name_of_content_to_require = '18-20';
      break;
    case 10:
      $name_of_content_to_require = '20-22';
      break;
    case 11:
      $name_of_content_to_require = '22-24';
      break;
    }
    if( $name_of_content_to_require ) {
      require_once __DIR__ . $name_of_content_to_require . '.php';
    } else {
      die('with some error, or throw an exception');
    }
