Question

我正在尝试制作一个动态标签，使用php和bootstrap根据您选择的类别显示项目，但它会在同一页面中返回整个项目...

这是我的代码

我不确定问题出在哪里！我正在上一个礼貌的课程，老师告诉我使用bootstrap3，但是我不想再次重写我的代码！在添加PHP之前，选项卡运行良好！我不知道问题出在哪里，但结果是我将所有项目都放在一个页面中，并且无法使用选项卡在它们之间切换！它们都显示在一个页面中，第一个页面！

Answer 1

在这个地方可能您有一个错误

Database::disconnect();
echo '</div>';
}

您需要像这样将结尾div移到右花括号}之外

Database::disconnect();
}
echo '</div>';

使用PHP和Bootstrap的动态标签在一页中显示所有项目
