我有一个基本的注册表单,其中包含所有输入和php验证的jaquery验证,以检查现有的电子邮件地址。但是,如果我输入相同的电子邮件地址并多次提交,我就不会收到任何验证消息,并且电子邮件会存储在数据库中。我无法理解为什么会发生这种情况,我认为我的代码中没有任何错误。
以下是PHP验证:
public function register_post(){
$register = new Register();
$register->loadFromPost();
$valid_error = array();
if($register->is_value_exist('email', $register->email)){
$valid_error[] = 'email already taken';
}
$regexp = "/^[^0-9][A-z0-9_]+([.][A-z0-9_]+)*[@][A-z0-9_]+([.][A-z0-9_]+)*[.][A-z]{2,4}$/";
if (!preg_match($regexp, $register->email)) {
$valid_error[] = "not a valid email";
}
$var_array = array($register->first_name, $register->last_name);
$regexp = "/^[a-zA-Z]{2,16}+$/";
foreach($var_array as $var){
if (!preg_match($regexp, $var)) {
$valid_error[] = "not a valid input value for first name or last name";
}
}
if(count($valid_error) == 0)
{
$hash = Membership::hash($register->password);
$register->password = $hash['password'];
$register->hash = $hash['salt'];
}
$register->save();
$redirect_url = SITE_URL . "home/index";
redirect($redirect_url);
}

您的保存和重定向始终会被调用,因为它们不在您的IF条件下。改为:
if(count($valid_error) == 0)
{
$hash = Membership::hash($register->password);
$register->password = $hash['password'];
$register->hash = $hash['salt'];
$register->save();
$redirect_url = SITE_URL . "home/index";
redirect($redirect_url);
}
只有在没有验证错误时才会调用这三行。您还需要创建一种方法将valid_errors发送回用户,以便在他们不被重定向时,他们知道原因。
由于有人评论过它......至于电子邮件的正则表达式,请看一下:http://www.regular-expressions.info/email.html。你不允许+或%或。 - 等等。

您可以像我的代码一样尝试使用完全jquery
$(document).ready(function(){
//validation
$("form[name='your form name']").validate({
rules: {
uname:{
required:true,
alphabetsnspace:true,
minlength: 3,
},
email:{
required:true,
email:true,
},
},
psw: {
required: true,
minlength: 5,
maxlength: 25,
},
rpsw: {
equalTo: "#psw",
minlength: 5,
maxlength: 25,
}
},
messages: {
uname:{
required:"Please enter your user name",
minlength:"User name should be more then 3 characters",
alphabetsnspace:"Only alphabets and numbers are allowd",
},
email:"Please enter a valid email address",
},
//calling php
submitHandler: function(form) {
$.ajax({
url :"register.php",
type:"post",
dataType : 'html',
data:$('#registerform').serialize(),
success: function(data)
{
//any function
}
});
});
});

尝试此操作以进行多次插入验证
if(isset($email))
{
$checkdata=" SELECT email FROM users WHERE email='$email' ";
$query=mysqli_query($conn,$checkdata);
if(mysqli_num_rows($query)>0)
{
echo "email already taken";
exit;
}
else
{
//inset
}
