Question

我有PHP代码我们可以调用此代码BLOCKONE：

$maker = "SELECT vidMaker FROM videoinformation";
if ($result = mysqli_query($con, $maker)) {
    while ($row = mysqli_fetch_row($result)) {
        $values = explode(',',$row[0]);
        foreach($values as $v)
        if (!empty($v)) {
           printf ("<img class=\"makerImg\" src=\"addVid/maker/%s.jpg\">", $v);
        }
    }
    mysqli_free_result($result);

}
else{
    echo"PM administrator with an error";
}

我有很多PHP代码：

    <!DOCTYPE html>
    <head>
    </head>

    <body>
    <?php>
    .
    .
    .
    .
    .
    .
    .
    .
    .
    .
    .
    .
    BLOCKONE
    .
    .
    .
    .
    .
    .
    .
    .
    .
    .
    .
    ?>
    </body>

</html>

问题是 BEFORE BLOCKONE所有mysqli查询都正常工作，我可以显示信息，图片等，但 AFTER BLOCKONE没有任何查询正在运行。

为什么我在这段代码中完全知道问题？因为如果删除它...完整的代码工作正常。而且我不太确定要解决它。

这是完整的代码：

<!DOCTYPE html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<?php include 'BSH.php' ?>
<link rel="stylesheet" type="text/css" href="CSS/ldvid.css">

        <!-- Setup video player-->
        <script type="text/javascript">

// here we get the incomming video id (videoinfo.php?id=123)
$video_id = $_GET['id'];

// build a database query to select the videoInformation

Answer 1

您假设获得多行，但您总是重写：

while ($row = mysqli_fetch_array($result)) {

在您的主循环中，您始终会重写$result和$row变量。

在while循环中，使用$result2和$row2。

PHP代码（mysqli）查询在特定代码之后无法正常工作
