在MySQL中正確的POST日期到日期時間的方式

Question

我創建了一個向數據庫發送數據的表單，所有的字段都在工作，除了日期，我認爲它是與格式有關，但我不確定如何去處理它。

HTML

<dt>Date of Purchase</dt> 
     <dd> 
      <select id="date_of_purchase" name="entry[date_of_purchase]"> 
      <option value="">Month</option> 
      <option value="Jan">Jan</option> 
      <option value="Feb">Feb</option> 
      <option value="Mar">Mar</option> 
      </select> 
      <select id="date_of_purchase" name="entry[date_of_purchase]"> 
      <option value="">Day</option> 
      <option value="1">1</option> 
      <option value="2">2</option> 
      <option value="3">3</option> 
      <option value="4">4</option> 
      </select> 
      <select id="date_of_purchase" name="entry[date_of_purchase]"> 
      <option value="">Year</option> 
      <option value="2013">2013</option> 
      <option value="2014">2014</option> 
      <option value="2015">2015</option> 
      <option value="2016">2016</option> 
      </select> 
    </dd> 

PHP

$stmt = DB::query(Database::INSERT, 'INSERT INTO `registration` (`first_name`, `last_name`, `date_of_purchase`) VALUES (:first_name, :last_name, :date_of_purchase)');     

$stmt->param(':first_name', $post['first_name']); 
$stmt->param(':last_name', $post['last_name']); 
$stmt->param(':date_of_purchase', $post['date_of_purchase']); 

Answer 1

你應該領域

<dt>Date of Purchase</dt> 
     <dd> 
      <select id="month_of_purchase" name="month_of_purchase"> 
      <option value="">Month</option> 
      <option value="Jan">Jan</option> 
      <option value="Feb">Feb</option> 
      <option value="Mar">Mar</option> 
      </select> 
      <select id="day_of_purchase" name="day_of_purchase"> 
      <option value="">Day</option> 
      <option value="1">1</option> 
      <option value="2">2</option> 
      <option value="3">3</option> 
      <option value="4">4</option> 
      </select> 
      <select id="year_of_purchase" name="year_of_purchase"> 
      <option value="">Year</option> 
      <option value="2013">2013</option> 
      <option value="2014">2014</option> 
      <option value="2015">2015</option> 
      <option value="2016">2016</option> 
      </select> 
    </dd> 

使用不同的名稱，然後構造日期

$stmt->param(':date_of_purchase', sprintf("%d-%d-%d", $post['day_of_purchase'], $post['month_of_purchase'], $post['year_of_purchase'])); 

（我假設$信息[ 'year_of_purchase']是一樣的$ _ POST [ 'year_of_purchase']）

更改您的代碼是這樣的：

HTML

<dt>Date of Purchase</dt> 
     <dd> 
      <select id="date_of_purchase" name="entry[month]"> 
      <option value="">Month</option> 
      <option value="Jan">Jan</option> 
      <option value="Feb">Feb</option> 
      <option value="Mar">Mar</option> 
      </select> 
      <select id="date_of_purchase" name="entry[day]"> 
      <option value="">Day</option> 
      <option value="1">1</option> 
      <option value="2">2</option> 
      <option value="3">3</option> 
      <option value="4">4</option> 
      </select> 
      <select id="date_of_purchase" name="entry[year]"> 
      <option value="">Year</option> 
      <option value="2013">2013</option> 
      <option value="2014">2014</option> 
      <option value="2015">2015</option> 
      <option value="2016">2016</option> 
      </select> 
    </dd> 

PHP

$stmt = DB::query(Database::INSERT, 'INSERT INTO `registration` (`first_name`, `last_name`, `date_of_purchase`) VALUES (:first_name, :last_name, :date_of_purchase)');     

$stmt->param(':first_name', $post['first_name']); 
$stmt->param(':last_name', $post['last_name']); 
$stmt->param(':date_of_purchase', $post['month'] . $post['day'] . $post['year']); // Just an example, I am pretty sure this won't work, change it according to your database 

Answer 3

其中一種方法可能是：

//in PHP 
//first : convert and valid the INPUT 
try{ 
    $date = DateTime.CreateFromFormat("d-m-Y",$post["day"]."-".$post["month"]."-".$post['year']); 
    //then you will convert it to MySQL format : 
    $stmt = DB::query(Database::INSERT, 'INSERT INTO `registration` (`first_name`, `last_name`, `date_of_purchase`) VALUES (:first_name, :last_name, :date_of_purchase)');     

    $stmt->param(':first_name', $post['first_name']); 
    $stmt->param(':last_name', $post['last_name']); 
    $stmt->param(':date_of_purchase', $date->format("Y-m-d h:i:s"); 
}catch(Exception $e){ 
    //here re-ask the date because it is false 
}
