我遇到的问题是我有两种形式。student_register.php 和 student_verify.php 因此，当用户填写注册表并提交时，表单会发布到 student_verify.php，但会忽略 student_register.php 上的所有 php 脚本。它忽略了我放下的所有验证约束。看下面（它确实连接到 MySQL）
我有一个名为 student_register.php 的表单，其中包括以下代码：
<?php
include_once("scripts/global2.php");
mysql_connect("mysql.cms.gre.ac.uk","****","****") or die("Could not connect to server");
mysql_select_db("mdb_mj046") or die("Could not select database");
$message = '';
if(isset($_POST['username'])) {
$username = $_POST['username'];
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$dob = $_POST['dob'];
$gender = $_POST['gender'];
$addline1 = $_POST['addline1'];
$addline2 = $_POST['addline2'];
$city = $_POST['city'];
$postcode = $_POST['postcode'];
$phone = $_POST['phone'];
$mobile = $_POST['mobile'];
$email = $_POST['email'];
$pass1 = $_POST['pass1'];
$pass2 = $_POST['pass2'];
$college_id = $_POST['college_id'];
//error handeling
//If all the fields have been inserted
if ( (!$username) || (!$fname) || (!$lname) || (!$dob) || (!$gender) || (!$addline1) || (!$addline2) || (!$city) || (!$postcode) ||(!$phone) || (!$mobile) || (!$email) || (!$pass1) || (!$pass2) || (!$college_id) ) {
$message = 'Please insert all fields in the form below!';
}else{
//Checking if the password matches
if($pass1 != $pass2){
$message = 'Your password fields do not match!';
}else{
//securing the data, if passwords do match
$username = preg_replace("#[^0-9a-z]#i","",$username);
$fname = preg_replace("#[^0-9a-z]#i","",$fname);
$lname = preg_replace("#[^0-9a-z]#i","",$lname);
$dob = preg_replace("#[^0-9a-z]#i","",$dob);
$gender = preg_replace("#[^0-9a-z]#i","",$gender);
$addline1 = preg_replace("#[^0-9a-z]#i","",$addline1);
$addline2 = preg_replace("#[^0-9a-z]#i","",$addline2);
$city = preg_replace("#[^0-9a-z]#i","",$city);
$postcode = preg_replace("#[^0-9a-z]#i","",$postcode);
$phone = preg_replace("#[^0-9a-z]#i","",$phone);
$mobile = preg_replace("#[^0-9a-z]#i","",$mobile);
//Encrypts the password
$pass1 = sha1($pass1);
//Gets rid of any unwanted characters
$email = mysql_real_escape_string($email);
//Check for Dublicates-USERNAME
$user_query = mysql_query("SELECT username FROM students WHERE username='$username' LIMIT 1") or die ("Could not check username");
$count_username = mysql_num_rows($user_query);
//Check for Dublicates-EMAIL
$email_query = mysql_query("SELECT email FROM students WHERE email='$email' LIMIT 1") or die ("Could not check username");
$count_email = mysql_num_rows($email_query);
if($count_username > 0){
$message = 'Your username is already in use';
}else if($count_email > 0){
$message = 'Your email is already in use!';
}else{
///Insert the members into the DB
$query=mysql_query("INSERT INTO students (username, fname, lname, dob, gender, addline1, addline2, city, postcode, phone, mobile, email, password, activationKey, active, college_id) VALUES ('$username','$fname', '$lname','$dob', '$gender', '$addline1','$addline2', '$city','$postcode','$phone','$mobile', '$email','$password', '$activationKey', '','$college_id' )") or die ("Could not insert your information");
$student_id = mysql_insert_id();
$message = 'You have now been registered!';
//insert the members
}
}
}
}

问题是，student_register.php 中的所有 PHP 代码都没有运行，它不检查错误或什么都不检查，它只是发布到 student_verify.php，这意味着插入的代码没有运行。这就是我的 student_verify.php 的样子：
<?php

我不明白为什么它无法验证 student_register.php 上的数据，谁能帮助我，亲切的问候
