Question

我想在我的网站上使用php添加两个mysql变量。我想采用“日期”并添加“条款”（这是一组天数：30,60,90）来生成“Due_Date”。

Home.php

  $query = mysql_query("select * from Book1");
    $query = mysql_query("SELECT id, rep, Date, Name, P_O, ADDDATE(Date, Terms) AS Due_Date, Terms, GREATEST(DATEDIFF(NOW(), Due_Date), 0) AS Aging, Open_Balance from Book1");

?>

<div id="wrapper">

    <!-- Sidebar -->
    <div id="sidebar-wrapper">
        <ul class="sidebar-nav">
            <li class="sidebar-brand">

因此，必须根据设定的条款确定到期日，因此30 = 30days =发票结束后的1个月。所以date = 10/23/2015 terms = 30 Due_Date将= 11/23/2015，然后根据新计算的due_date确定老化。

addInvoice.php

//escape user inputs for security
$rep = mysqli_real_escape_string($link, $_POST['rep']);
$date = mysqli_real_escape_string($link, $_POST['Date']);
$name = mysqli_real_escape_string($link, $_POST['name']);
$P_O = mysqli_real_escape_string($link, $_POST['P_O']);
$due_date = mysqli_real_escape_string($link, $_POST['Due_Date']);
$terms = mysqli_real_escape_string($link, $_POST['terms']);
$aging = mysqli_real_escape_string($link, $_POST['aging']);
$open_balance = mysqli_real_escape_string($link, $_POST['open_balance']);

//attempt insert query execution
$sql = "INSERT INTO Book1 (Rep, Date, Name, P_O, Due_Date, Terms, Aging, Open_Balance)
VALUES ('$rep', '$date', '$name', '$P_O', 'ADDDATE(Date, Terms) AS $due_date', '$terms', 'GREATEST(DATEDIFF(NOW(), Due_Date), 0) AS $aging', '$open_balance')";
if(mysqli_query($link, $sql)){
    header("location: Home.php");
} else {
    echo "ERROR: Could not execute $sql." .mysqli_error($link);
}

//close connection
mysqli_close($link);

现在的问题是，当我添加新发票时，它将完美地计算到期日，但现在它不会计算老化。有什么帮助吗？

Answer 1

SELECT id,
       rep,
       Date,
       Name,
       P_O,
       ADDDATE(Date, Terms) AS DueDate,
       Terms,
       GREATEST(DATEDIFF(NOW(), ADDDATE(Date, Terms)), 0) AS Aging,
       Open_Balance
from   Book1

Answer 2

检查您是否正在寻找：

echo "<td>". date('m/d/Y', strtotime($row['Date'] .' +'. $row['Terms'] .' days')) ."</td>";

Answer 3

function calculate_postpone_due_date($billingcycle)
{
switch($billingcycle)
{
    case "Monthly":         $months = 1; break;
    case "Quarterly":       $months = 3; break;
    case "Semi-Annually":   $months = 6; break;
    case "Annually":        $months = 12; break;
    case "Biennially":      $months = 24; break;
    case "Triennially":     $months = 36; break;
    default:                $months = 0; break;
}


if ($months == 0)
    return FALSE;    

$today = date('Y-m-d');
$next_due_date = strtotime($today.' + '.$months.' Months');
return date('Y-m-d', $next_due_date);

}

Answer 4

试试这个，

$NewDate = date('Y-m-d', strtotime($day . " $terms"));
echo $NewDate;

将两个MySql变量一起添加，使用php
