Question

我在网上发现了一些教程和一些免费代码，并试图制作这个投票页面，但投票没有提交，页面也没有被重定向。我做错了什么？我如何解决它？我试了几个小时，但我无法得到它。这是代码，但真实姓名替换为John Doe。

<?php
if($_POST['formSubmit'] == "Submit")
{
    $errorMessage = "";

    if(empty($_POST['varVote']))
    {
        $errorMessage .= "<li>error</li>";
    }


    $varVote = $_POST['varVote'];

    if(empty($errorMessage)) 
    {
        $fs = fopen("doe.csv","a");
        fwrite($fs,$varName . ", \n");
        fclose($fs);

        header("Location: thank.htm");
        exit;
    }
}
?>

Answer 1

你的if条件无法进入php块

if($_POST['formSubmit'] == "submit")

Answer 2

你错过了一些事情：

第1行

if($_POST && $_POST['formSubmit'] == "submit")

提交按钮值等于“提交”而不是“提交”

第18行

fwrite($fs,$varVote . ", \n");

第13行设置的变量名是“$ varVote”而不是“$ varName”

Answer 3

你在php代码中给出了错误的名字。

试试吧

<?php 
     if ($_POST['formSubmit'] == "submit" )
     {
         inner block;
         //ETC.........
     }
?>

我的php表单代码有什么问题？
