<?php
if(isset($_POST['submit']))
{
    $fname = $_POST['fname'];
    $lname = $_POST['lname'];
    $age = $_POST['age'];
    $sex = $_POST['sex'];
    $address = $_POST['address'];
    $city = $_POST['city'];
    $zip = $_POST['zip'];
    $grade = $_POST['grade'];
    $email = $_POST['email'];
    $file = fopen("schooldetails.txt","a") or die("file not open");
    $s = $fname.",".$lname.$age.$sex.$address.$city.$zip.$grade.$email."\n";
    fputs($file,$s) or die ("cannot write data");
    fclose($file);

解决方案

您的 POST 数据可能不包含 POST[submit']，请尝试更改

if(isset($_POST['submit']))

至

if(isset($_POST))
