Question

我已经尝试了一切，但是......选框显示在两行中，但我希望它在一行上。

这是我的代码：

<?php
    $con=mysqli_connect("localhost","Protected","Protected","Protected");// Check connection
    if (mysqli_connect_errno()) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }
    $result = mysqli_query($con,"SELECT * FROM questions");
    while($row = mysqli_fetch_array($result)) {
        echo "<style>";
        echo "marquee { white-space: pre; }";
        echo "</style>";
        echo "<marquee>";
        echo '<span class="name">' . '&#8226;' . "<b>Naam:</b> " . $row['naam'] . "<b> Vraag:</b> " .       $row['vraag'] . "</span>". "</marquee>";
    }
    mysqli_close($con);
?>

有人知道我的代码中的问题吗？

Answer 1

您的代码必须像这样

<?php
    $con=mysqli_connect("localhost","Protected","Protected","Protected");// Check connection
    if (mysqli_connect_errno()) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }
    $result = mysqli_query($con,"SELECT * FROM questions");
    echo "<style>";
    echo "marquee { white-space: pre; }";
    echo "</style>";
    echo "<marquee>";
    while($row = mysqli_fetch_array($result)) {


        echo '<span class="name">' . '&#8226;' . "<b>Naam:</b> " . $row['naam'] . "<b> Vraag:</b> " .       $row['vraag'] . "</span>";
    }
    echo "</marquee>";
    mysqli_close($con);
?>

Answer 2

将此代码放在while循环的一边，Reason显示两次原因，您从查询返回两行

echo "<style>";
       echo "marquee { white-space: pre; }";
       echo "</style>";

       echo "<marquee>";

while循环后的最后一行echo "</marquee>";，以及循环上面的其余行

Marquee显示在两行而不是一行 - HTML＆amp; CSS
