如何检查php中是否按下输入类型按钮？

Question

isset()函数可用于检查是否按下了输入类型提交,但有没有办法检查是否按下了输入类型按钮？在我的代码中,该按钮除了调用.Onclick()事件上的函数之外什么都不做,然后刷新页面并在php中创建一个数据库条目......我希望它只在按下按钮后才能进行输入...并且由于其他原因,我无法使用提交类型...以下是一些代码:

function send()
{
    var events = document.getElementById("event").value;
    location.href = "calm.php?day=" + xx + "&month=" + yy + "&year=" +
                    zz + "&events=" + events;
}

<input name="Button"
       type="button"
       id="submit"
       onclick="send(this.form)"
       value="Button" />

<?php
    session_start();
    include_once "connect_to_mysql.php";
    $day = $_GET['day'];
    $month = $_GET['month'];
    $year = $_GET['year'];
    $events = $_GET['events'];
    $userid = $_SESSION['id'];
    if (isset($_POST['button']))
    {
        $sql = mysql_query("INSERT INTO events (userid,month,day,year,events)
                            VALUES('$userid','$month','$day', '$year','$events')")
               or die (mysql_error());
    }
?>

Answer 1

isset($_POST['Button'])你错过了首都B.您需要将其与输入的name属性相匹配.
