如何使用PHP（和HTML）从SQLite中选择，插入，更新和删除数据

[英]How to SELECT, INSERT, UPDATE and DELETE data from SQLite with PHP (and HTML)

问题描述

我确实有一个SQLite Web Interface ，该SQLite Web Interface应该从SQLite表中进行SELECT，INSERT，UPDATE和DELETE数据。 不幸的是，似乎只有SELECT查询有效。 我无法插入，更新或删除。

sshTunnel.sqlite-> mydata 

CREATE TABLE "mydata" ("ID" INTEGER PRIMARY KEY  AUTOINCREMENT  NOT NULL , "SSH_USER" VARCHAR, "SSH_IP" VARCHAR, "SSH_PORT" VARCHAR, "SSH_PW" VARCHAR, "SSH_KEYFILE" VARCHAR, "TUNNEL_LOCAL_INTERFACE" VARCHAR, "TUNNEL_LOCAL_PORT" VARCHAR, "TUNNEL_REMOTE_IP" VARCHAR, "TUNNEL_REMOTE_PORT" VARCHAR, "DESCRIPTION" VARCHAR)

这是我的代码片段...

index.php 

<script>
$(document).ready(function()
{
    function fetch_data()
    {
        $.ajax({
            url:"select.php",
            method:"POST",
            success:function(data)
            {
                $('#live_data').html(data);
            }
        });
    }
    fetch_data();

    $(document).on('click', '#btn_add', function()
    {
        var SSH_USER = $('#SSH_USER').text();
        var SSH_IP = $('#SSH_IP').text();

            }
        });
    });

        var TUNNEL_REMOTE_PORT = $(this).data("id9");
        var DESCRIPTION = $(this).data("id10");

        if(confirm("Are you sure you want to edit this?"))
        {
            $.ajax({

                    fetch_data();
                }
            });
        }
    });

您确定脚本正在编译并正在运行吗？ 我在insert.php中发现引号的一种奇怪用法：您用单引号打开了字符串，并且它们使用双引号终止和连接了...与delete.php相同。

另外，请确保对要放入查询中的所有数据“加上”。 如果在单引号中输入任何内容，则所有查询都会失败，当然，安全性也很重要。
