Several buttons to print off different sections of code

在我的项目中，我需要能够打印出信件，其中包括关于租用公交车的信息。我没有太多经验，所以我所做的就是把非常简单的字母放在网页上，然后我的想法是能够为每个字母都有一个打印按钮，并打印出我想要打印的内容。我想我已经做了所有的事情，但我无法让打印工作，这个按钮似乎是一个毫无意义的按钮。我的JavaScript编码很差，所以我不太确定如何解决这个问题。如有任何帮助，我们将不胜感激。我从如何使用php下载/打印页面的特定部分中获得了很多想法，但我有这个特定的问题，所以仅仅看它对我没有特别的帮助

<?php
include "connection.php";
$id = 0;
$result = mysql_query("SELECT cost, date, time, pickuplocation, destination,    numberofpeople, endtime, hireid, payment FROM hire WHERE information='letter'");
while ($row = mysql_fetch_array($result)) {
    $id = $id + 1;
    echo "<div id=" . $id . ">";
    echo "The Hurst and Hassocks Community Bus Association <br> 
            Invoice <BR> <BR>
            Thank you for hiring with the Association. <BR>
            The total cost for the hire is: &pound;" . $cost = $row['cost'] . "<BR><BR>
            Your details for the hire: <BR>
            Date: " . $date = $row['date'] . " <BR>
            Time: " . $time = $row['time'] . " <br>
            Pick up location: " . $pickuplocation = $row['pickuplocation'] . " <br>

            Hire ID: " . $hireid = $row['hireid'] . " <br><br>";
    if (($payment = $row['payment']) == "cheque") {
        echo "In order to pay for your hire and therefore confirm it, please address your     cheque to The Hurst and Hassocks Community Bus Association and include the total cost. Put your cheque in an envelope and send to the following address:  <BR><BR>";
    }
    if (($payment = $row['payment']) == "transfer") {
        echo "In order to pay for your hire and therefore confirm it, you will need to make an online bank transfer to The Hurst and Hassocks Community Bus Association. You will need to enter the Account Number and Sort Code when making the transfer. <BR>
            Account Number:  <BR>
            Sort Code: <BR><br>";
    }
    echo "We will need to receive payment at least 3 days before the date of the hire in order to confirm details with you. If payment is not received by then, the hire will be cancelled.

    echo "</div>";
    echo "<input type='button' value='Print' onclick='printPage(" . $id . ");'></input>";
    echo $id;
    echo "<br>--------------------------------------------------------------<br><br>";
}
?>
<script>
    function printPage('<?php $id; ?>') {
        var html='<html>';
        html+= document.getElementById(id).innerHTML;
        html+='</html>';
        var printWin = window.open('','','left=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status =0');
        printWin.document.write(html);
        printWin.document.close();
        printWin.focus();
        printWin.print();
        printWin.close();
    }
</script>

您需要更改：

function printPage('<?php $id; ?>') {

收件人：

function printPage(id) {

试试看？
