php - 从多个复选框和文本字段插入值

Question

我是 PHP 的初学者。我遇到了一个问题。我的想法是，我必须将 Actor 分配给选定的电影，并为每个 Actor 添加一个角色。我需要从列表中选择几个值，并通过文本字段为每个值添加描述。我的代码将所有检查的值添加到数据库中，但它使文本字段中的值变得困惑，检查的值与描述不匹配。我将非常感谢您的帮助! 我的代码: 形式:

<?php
$sqlquery = "SELECT artistId, firstname, lastname from $artists order by 2";
$result = mysqli_query($connect, $sqlquery);
if($result) {
    echo "<table class=\"addactor\">";
    echo "<tr>
        <td id=\"text\" colspan=\"2\"><h3>Assign an actor to the movie</h3></td>
    </tr>";
    while($sqlRow = mysqli_fetch_array($result, MYSQL_ASSOC)) {
        echo "<tr>";
        echo "<td>";
        echo "<input type=\"checkbox\" name=\"checkbox[]\" value=\"" . $sqlRow['artistId'] . "\"/> " . $sqlRow['firstname'] . " " . $sqlRow['lastname'] . "</td><td><input type=\"text\" name=\"textbox[]\"/></td>";
        echo "</tr>";

    }
    echo "<tr><td align=\"right\"><input type=\"submit\" name=\"submit\" id=\"submit\" value=\"Add\"></td><td><input type=\"reset\" name=\"reset\" id=\"reset\" value=\"Reset\"></td></tr></table>;";

}
print '</table>';

与数据库的连接位于另一个文件中，该文件包含在此处。

第二部分:

if($_POST) {
        $checkbox = $_POST['checkbox'];
        $txt = $_POST['textbox'];
        $len = sizeof($checkbox);
        for($i = 0; $i < $len; $i++) {
            $sqlqr = "INSERT INTO $role (artistId, movieCode, Description) VALUES ('" . $checkbox[$i] . "', '" . $_POST['moviecode'] . "', '" . $txt[$i] . "')";
            mysqli_query($connect, $sqlqr);
        }
        $query = "INSERT INTO $movies(movieCode, title, dateOfIssue,category, description, image) VALUES ('" . $_POST['moviecode'] . "', '" . $_POST['title'] . "', '" . $_POST['dateofissue'] . "','" . $_POST['category'] . "', '" . $_POST['desc'] . "', '" . $_POST['image1'] . "')";
        mysqli_query($connect, $query);
        if(mysqli_query($connect, $query) || mysqli_query($connect, $sqlqr)) {
            echo "<h4>1 record added</h4>";

        }
        else {
            die('Error: ' . mysqli_error($connect));
        }
        print '</form>';
    }

未选中的值不会提交，并且 checkbox 数量与 textbox 数量不同。 您应该为输入名称数组提供相同的键:

$i = 0;
while($sqlRow = mysqli_fetch_array($result, MYSQL_ASSOC)) {
    echo "<tr>";
    echo "<td>";
    echo "<input type=\"checkbox\" name=\"checkbox[".$i."]\" value=\"" . $sqlRow['artistId'] . "\"/> " . $sqlRow['firstname'] . " " . $sqlRow['lastname'] . "</td><td><input type=\"text\" name=\"textbox[".$i."]\"/></td>";
    echo "</tr>";
    $i++;
}

也使用此代码:

$checkbox = $_POST['checkbox'];
$txt = $_POST['textbox'];
foreach ($checkbox as $key => $value)
    $sqlqr = "INSERT INTO $role (artistId, movieCode, Description) VALUES ('" . $value . "', '" . $_POST['moviecode'] . "', '" . $txt[$key] . "')";
    mysqli_query($connect, $sqlqr);
}
