似乎无法从我的 php 本地主机删除或添加到数据库

Question

我正在与其他人一起构建部分网站，但是当我想删除选中的项目时，会出现错误 “未找到 在服务器上找不到请求的 URL。如果您手动输入 URL，请检查拼写并重试。”

网址是http://127.0.0.1:8080/delete

这是我的脚本：

我尝试更改删除路线，但故障排除失败。

Answer 1

我认为您没有传递路线的 id。如果您使用 url_for()，您可以使用 jinja 将 id 字段传递给您的 python deleteMovement 函数。

<form method ="POST" action="{{ url_for('deleteMovement', id=items.id) }}">
    <button type = submit class="btn btn-danger">Delete</button>
</form>

如果 items.id 为 1，它将创建一个类似 http://127.0.0.1:8080/delete/1 的 url。
