以下是我网站上register.php的代码 . 此代码允许用户注册我的网站，在点击提交按钮时创建用户名，电子邮件，密码等的MySQL条目 . 该按钮名为“reg”并使用$ _POST . 单击提交按钮后，php将运行多个if语句，以确保用户输入的信息有效且不存在 . 如果用户存在，或者在提交中出错，则设置php变量$ errormessage并且应该将其回显 . 现在，我的SUBMIT按钮不会像被按下一样 . 没有错误消息，没有插入SQL行，没有 .
<?php
if( $_POST['reg']){
/* Make sure values are correct and valid */
$getuser = $_POST['user'];
$getemail = $_POST['email'];
$getpass = $_POST['password'];
$getrepass = $_POST['retypepassword'];
/* Check to see if username entererd */
if($getuser){
/* Check to see if email entererd */
if($getemail){
/* Check to see if password entererd */
if($getpass){
/* Check to see if retyped password entererd */
if($getrepass){
/* Check to see if passwords are the EXACT same */
if($getpass === $getrepass){
/* Check to see if VALID email is entered */
if( (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, ".")) ){
/* Email is valid mysql query */
require ("./connect.php");
$query = mysql_query("SELECT * FROM users WHERE username ='$getuser'");
$numrows = mysql_num_rows($query); /* Is mysql returns zero, user doesnot exist. */
/*check if email exists */
if($numrows == 0) {
$query = mysql_query("SELECT * FROM users WHERE email ='$getemail'");
$numrows = mysql_num_rows($query);

$date = date("F d, Y");
$code = md5(rand());

我认为你混合按钮's type attribute, ie it'不是按钮而是提交
所以，我猜你有一个正常的文本输入字段，但你的CSS欺骗你的眼睛 . 尝试写入:)
要通过按钮提交表单，您可以使用：
