我想在Carousel Slider中添加一些图像。

我从管理面板发布了图像和标题，并将其保存到数据库。当我从数据库中提取数据时，结果是：请参见我添加了图像。没有图片显示。 enter image description here

<?php
    $veriler = $db->query("SELECT * FROM haberlerekle",PDO::FETCH_ASSOC)->fetchAll();
?>

我认为，代码需要。

Answer 1

左上角（https://i.stack.imgur.com/7UgIN.jpg）的符号表示“链接断开”。这意味着该路径未指向文件。或者您可能需要绝对/相对路径（HTML showing broken image）

确保您尝试粘贴到src属性中的图像的路径确实存在。

U可以通过粘贴

的内容来尝试

$ row [“ haberekle_konu”]

URL后面的

。如果图像未出现，则路径不正确。

最终，我找到了我想要的代码。我找到了youtube。下面的代码和youtube链接。

    <?php
    $veriler = $db->query("SELECT * FROM haberlerekle ORDER BY haberekle_id DESC LIMIT 12",PDO::FETCH_ASSOC)->fetchAll();

    ?>
