私のプロジェクトでは、バスの雇用に関する情報を含む手紙を印刷できる必要があります。私はあまり経験がないので、非常に単純な文字をWebページに配置し、各文字に印刷ボタンを設定して、印刷したいものを印刷できるようにすることを考えました。私はすべてをやったと思いますが、印刷を機能させることができません。ボタンは無意味なボタンのようです。私のJavaScriptコーディングは貧弱なので、この問題を解決する方法がよくわかりません。どんな助けでもありがたいです。PHPを使用してページの特定の部分をダウンロード/印刷する方法から多くのアイデアを取り入れましたが、この特定の問題があるため、それを見るだけでは特に役に立ちません。

<?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>

変更する必要があります：

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

に：

function printPage(id) {

それを試してみませんか？
