    input.value = "text"+i;

    input.size = 10;

    t1.push(input);

    removeButton.onclick = function(e) {

        this.parentNode.parentNode.removeChild(this.parentNode);
        return(false);

    };

    div.appendChild(removeButton);

这是一个正在运行的代码......我想知道什么代码可以将每个文本框的值放到mysql数据库中 mybe使用这个：

$sql = "UPDATE `sampledb` SET  `text1` =  'anyvaluethatuserinputs' && `text2` =  'anyvaluethatuserinputs' && `text3` =  'anyvaluethatuserinputs'";

但是如何...

Answer 1

在generate.php中添加此行。您将能够在字符串中获取文本框的值以及文本框的ID。

<?php

$sql = "UPDATE `sampledb` SET  ";


if(isset ($_GET))
{

    foreach ($_GET as $key => $value) 
        $sql .= "$key = '$value'  , ";

}

$sql= substr_replace ($sql , '', strlen($sql) -2 , 1);
echo $sql;

    //here establish the connection and pass the $sql as the query

?>

输入框值将保存到mysql数据库
