我在codeigniter中写了注册表。它将信息提交给数据库，但它不显示验证错误，错误消息和成功消息。但是当我写console.log(response);时，它会在控制台中显示这些消息。问题出在哪儿？
以下是我的观点：
<div id="messages"></div>
<?php $attributes = array('class' => 'rex-forms', 'name' => 'registrationform', 'id' => 'registrationform'); ?>
<?= form_open_multipart('user/register', $attributes); ?>
<div class="form-group">
<input name="username" type="text" class="form-control" placeholder="Имя пользователя">
</div>
<div class="form-group">
<input name="mail" type="email" class="form-control" placeholder="Электронный адрес">
</div>
<div class="form-group">
<input name="password" type="password" class="form-control" placeholder="Пароль">
</div>
<div class="form-group">
<input name="password2" type="password" class="form-control" placeholder="Повторный ввод пароля">
</div>
</div>
<div class="modal-footer">
<button type="submit" name="submitforreg" class="rex-bottom-medium rex-btn-icon btnsubmitforreg">
<span class="rex-btn-text">регистрация</span>
<span class="rex-btn-text-icon"><i class="fa fa-arrow-circle-o-right"></i></span>
</button>
</div>
</form>
这是我的控制器：
$validator = array('success' => false, 'messages' => array());
$validate_data = array(
array(
'field' => 'username',
'label' => 'Username',
'rules' => 'trim|required|alpha_dash|min_length[3]|max_length[30]|is_unique[instructors.instructors_slug]xss_clean'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'trim|required|md5|min_length[3]'
),
array(
'field' => 'password2',
'label' => 'Confirm Password',
'rules' => 'trim|required|md5|matches[password]'
),
array(
'field' => 'mail',
'label' => 'email',
'rules' => 'trim|required|valid_email|is_unique[instructors.mail]'
)
);
$this->form_validation->set_rules($validate_data);
$this->form_validation->set_message('is_unique', 'The {field} already exists');
$this->form_validation->set_error_delimiters('<p class="text-danger">', '</p>');
if ($this->form_validation->run() == FALSE)
{
// fails
$validator['success'] = false;
foreach ($_POST as $key => $value) {
$validator['messages'][$key] = form_error($key);
}
} else {
//insert the user registration details into database
$data = array(
'instructors_slug' => $this->input->post('username'),
'mail' => $to_email,
'password' => $this->input->post('password')
);
// insert form data into database
if ($this->user_model->insertUser($data)) {
if ($this->user_model->sendEmail($to_email)) {
// successfully sent mail
echo '<div class="alert alert-success text-center">You are Successfully Registered! Please confirm the mail sent to your Email-ID!!!</div>';
}
else
{
// error
echo '<div class="alert alert-danger text-center">'.$to_email.' gondermir '.$this->email->print_debugger().'</div>';
}
}
else
{
// error
echo '<div class="alert alert-danger text-center">daxil elemir</div>';
redirect('user/register');
}
}
echo json_encode($validator);
这是我的register.js ajax文件：
$(document).ready(function() {
$("#registrationform").unbind('submit').bind('submit', function() {
var form = $(this);
$.ajax({
url: form.attr('action'),
type: form.attr('method'),
data: form.serialize(),
dataType: 'json',
success:function(response) {
console.log(response);
if(response.success == true) {
$("#messages").html(response.messages);
$("#registrationform")[0].reset();
$(".text-danger").remove();
$(".form-group").removeClass('has-error').removeClass('has-success');
}
else {
$.each(response.messages, function(index, value) {
var element = $("#"+index);
$(element)
.closest('.form-group')
.removeClass('has-error')
.removeClass('has-success')
.addClass(value.length > 0 ? 'has-error' : 'has-success')
.find('.text-danger').remove();
$(element).after(value);
});
}
} // /success
}); // /ajax
return false;
});
});

在您的代码中，您没有在每个字段中添加ID。您需要添加id，如下所述。
<?php $attributes = array('class' => 'rex-forms', 'name' => 'registrationform', 'id' => 'registrationform'); ?>
<?= form_open_multipart('user/register', $attributes); ?>
<div class="form-group">
<input name="username" id="username" type="text" class="form-control" placeholder="Имя пользователя">
</div>
<div class="form-group">
<input name="mail" id="mail" type="email" class="form-control" placeholder="Электронный адрес">
</div>
<div class="form-group">
<input name="password" id="password" type="password" class="form-control" placeholder="Пароль">
</div>
<div class="form-group">
<input name="password2" id="password2" type="password" class="form-control" placeholder="Повторный ввод пароля">
</div>
</div>
<div class="modal-footer">
<button type="submit" name="submitforreg" class="rex-bottom-medium rex-btn-icon btnsubmitforreg">
<span class="rex-btn-text">регистрация</span>
<span class="rex-btn-text-icon"><i class="fa fa-arrow-circle-o-right"></i></span>
</button>
</div>
</form>
另外在你的ajax成功功能中你可以查看下面给出的状态。
从if(response.success == true){到if(response.success){
如果不起作用，请告诉我。

你应该从这个答案中得到这个想法。
用于从ajax获取验证错误。
这是发送示例电子邮件以进行验证的Ajax脚本：
$.ajax({
type: 'POST',
url: URL,
data: {
email: email
},
success: function(data) {
// Your error message
// Now you can show that anywhere you want inside the view.
}
});
现在我Setting Rules Using an Array
我已使用form_validation.php
email_verification' => array(
array(
'field' => 'email',
'label' => 'Email',
'rules' => 'required|max_length[100]|valid_email|is_unique[your_table.email_column_name]',
'errors' => array(
'required' => 'Email is required.',
'valid_email' => 'Plese Enter Valid Email',
'is_unique' => 'That Email is already taken. Try Again With New Email.'
)
)
)
这是控制器：
public function check_email_validation(){
$emial = $this->input->post();
$this->form_validation->set_error_delimiters('<span class="error">', '</div>');
//Now Chaeck for valid email here
if (($this->form_validation->run('email_verification') == FALSE)){
// sending error message to the view.
echo form_error('email');
} else {
unset($_POST);
echo '<span style="color:green;" id="emailIsValid">Email Is Valid</span>';
}
//echo "<span style='color:green;'>Email Is Valid</span>";
}
