在将发送电子邮件功能包含到 Controller 后，我没有得到响应，但代码完美地发送电子邮件，唯一的问题是没有得到响应。如果我删除发送电子邮件的代码，那么在这种情况下， Controller 的响应很好，但是当我包含电子邮件功能时，我不会在 jquery View 代码上收到响应。
我发布了我的 Controller 代码和电子邮件功能代码，还发布了我的 jQuery，以便您可以查看它。
Controller 代码: /*****创建新客户********/
public function createcustomer()
{
$this->form_validation->set_rules("firstname", "First Name", "required");
$this->form_validation->set_rules("lastname", "Last Name", "required");
$this->form_validation->set_rules("email", "Email", "required|is_unique[gab_users.email]|trim|xss_clean");
$this->form_validation->set_rules('password', 'Password', 'required|min_length[5]|matches[confirmpassword]|md5');
$this->form_validation->set_rules('confirmpassword', 'Password Confirmation', 'required|min_length[5]');
if($this->form_validation->run() === FALSE)
{
die("fail");
}
else
{
$activation_code = sha1(uniqid($this->input->post('email'),'true'));
$data = array("firstname"=>$this->input->post('firstname'), "lastname"=>$this->input->post('lastname'), "email"=>$this->input->post('email'), "password"=>$this->input->post('password'), "ip"=>$this->input->post('ip'), "activation_code"=>$activation_code, "created_on"=>now(), "active"=>1, "group"=>2);
$verifyCreate = $this->index_model->set_user($data);
if($verifyCreate === "success")
{
if($this->sendEmail() === 'done')//If I remove this line and write only die('done'); its work perfectly. model is working fine data is saved in the database in both conditions. The big issue is response?
{die('done');}
}
else
{
die("invalid");
}
}
}
**/******Send Email********/**
public function sendEmail()
{
$this->load->library('email');
$this->email->set_newline("\r\n");
$this->email->from('email@gmail.com', 'Name');
$this->email->to('*****@gmail.com');
$this->email->subject(' My mail through codeigniter from localhost ');
$this->email->message('Hello World…');
if (!$this->email->send()) {
die(show_error($this->email->print_debugger()));
}
else {
die("done"); //I have also check it by return same thing is happened
}
}
我在 View 端编写的 Jquery 代码:
<script>$().ready(function() {
$("#regForm").validate({
rules:
{
firstname: "required",
lastname: "required",
email:
{
required: true,
email: true
},
password:
{
required: true,
minlength: 5
},
confirmpassword:
{
required: true,
minlength: 5,
equalTo: "#password"
}
},
messages:
{
firstname: "First Name Required",
lastname: "Last Name required",
email: "Please enter a valid email address",
password:
{
required: "Please provide a password",
minlength: "Your password must be at least 5 characters long"
},
confirmpassword:
{
required: "Please provide a password confirmation",
minlength: "Your password must be at least 5 characters long",
equalTo: "Please enter the same password as above"
}
},
submitHandler: function(form)
{alert('customer register');
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>createcustomer",
data: $(form).serialize(),
timeout: 3000,
success: function(data) {
alert(data);
if(data == 'done')
{
$.blockUI({ css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
} });
setTimeout($.unblockUI, 2000);
$('#successreg').show().delay(7000).fadeOut();
window.setTimeout(function(){
window.location.href = "<?php echo base_url(); ?>customer";
}, 7000);
}
else if(data == 'invalid')
{
$.blockUI({ css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
} });
setTimeout($.unblockUI, 2000);
$('#regerrormsg').show().delay(7000).fadeOut();
window.setTimeout(function(){
window.location.href = "<?php echo base_url(); ?>customer";
}, 7000);
}
else
{
$.blockUI({ css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
} });
setTimeout($.unblockUI, 2000);
$('#regerrormsg').show().delay(7000).fadeOut();
window.setTimeout(function(){
window.location.href = "<?php echo base_url(); ?>customer";
}, 7000);
}
}
});
return false;
}
});
}); </script>
请告知为什么我在使用 sendEmail 函数后，在发送电子邮件并将数据保存到数据库时没有收到 Controller 的响应，但没有收到响应，因此无法向用户显示确认消息。
最佳答案
编辑:请注意以下所有内容也都是好东西，但您的实际问题是如何从 sendMail() 函数返回。 Die 是错误的，因为它会杀死脚本(线索就在名称中)，因此它不会继续允许调用脚本响应。更改为:
....
if (!$this->email->send()) {
die(show_error($this->email->print_debugger()));
}
else {
return "done";
}
对于 http 响应来说，Die 并不是一个好的做法，因为它可能被解释为一个损坏的页面。为什么不返回 jQuery 喜欢的东西，例如 json 字符串。例如:
header('Content-Type: application/json');
if($verifyCreate === "success")
{
if($this->sendEmail() === 'done'){
echo json_encode(array('status'=>'success'));
return;
}
}
else
{
echo json_encode(array('status'=>'fail'));
return;
}
然后在你的 jQuery 中
//redacted
success: function(data) {
if(data.status==='success'){
//do some success stuff
}
else if(data.status==='fail'){
//do some fail stuff
}else{
//do some unexpected stuff
}
}
您可能还需要在 $.ajax 对象中设置 contentType:json。
