如何把 htmlform表单提交到数据库

如何把 htmlform表单提交到数据库,第1张

1:首先要使用PHP的超全局变量 $_GET 和 $_POST 用于收集表单数据(form-data)

2:然后使用INSERT INTO 语句用于向数据库表中插入新记录。

很明显是字符集的问题,你数据库的字符集跟你插入时设置的字符集不匹配。

要么在config中连接数据库字段中进行设置

<appSettings>

<add key="Connection" value="Server=127.0.0.1User ID=rootPassword=Database=数据库CharSet=gb2312"/>

</appSettings>

要么在程序中指定

MySQLCommand mCommand = new MySQLCommand("set names gb2312", Connection)

$(function () {

//定义一个全局变量i,用来标识添加了几行

var row = 0

var strValue = ""

//将一行添加到table中去

$('#btnInsert').click(function () {

row++

//字符串拼接tr一行中的内容

var tr = "<tr>"

for (var i = 0i <3i++) {

tr += "<td><input id='" + row + "text'" + i + "+' type='text' value=" + row +""+ i + " /></td>"

$("#tab").append(tr)

})

//删除添加的行,先判断checkbox是否选中,然后删除

$('#btnDelete').click(function () {

$("input[name=ckb]:checked").each(function () { $(this).parent().parent().remove()})

//将i遍历,判断是否存有值,如果有将数据插入数据库
