php pdo 代码从 table 到 select 日期并在 selected 日期添加 +1 个月

Question

table 姓名 - receipt_entry

列名称 - 开始日期

我需要 select 从 receipt_entry table 开始日期并在 select 日期中添加 + 1 个月并显示在另一个日期文本框中。

对于EX -

开始日期 = 23-02-2015 然后在日期文本框中显示 23-03-2015。

此函数适用于列表框的 selected 事件更改...

除了这个日期文本框之外，我的代码中的所有东西都在工作..没有得到正确的日期....这个在我的文本框中显示错误的日期..

Answer 1

您需要告诉您要添加多少个月，php默认情况下不知道

    $generateddate = date("d-m-Y", strtotime($startingdate . " + 1 MONTHS"));

Answer 2

$generateddate = date("d-m-Y", strtotime("$startingdate + 1 MONTH"));

Answer 3

需要添加月数...您要添加多少个月。

 <?php
    require_once('includes/config.php');
    $q = $_GET['q'];
    $city = $database->getRows("SELECT * FROM receipt_entry WHERE coupon = :coupon", array(':coupon'=>"$q"));  
    $info = array();
    foreach($city as $row)
    {    
        $startingdate = $row['startingdate'];   
        $generateddate = date("d-m-Y", strtotime($startingdate . " +" . " 1MONTHS"));   
        //$generateddate = date("d-m-Y", strtotime($startingdate) . " + MONTHS");

        $cWeb[] = $row['customer_name'];
        $receipt = $row['receipt_no'];
        $book = $row['book_no'];
        $booking = $row['bookingdate'];      
        $info[] = array('web' => $cWeb,'rec' =>$receipt,'book' =>$book,'booking' =>$booking,'date' =>$generateddate );
    }
    echo json_encode($info);
    ?>
