How to get the success message in the same page after submitting the form?

I'm trying to display a success and error message in the same page. What do i need to change?
The form is to send the data to the database and then show a success message in the same page, then redirect to another page. I've tried changing the ID value in the form and the java script, i still get the same results, the data is sent to the database, it redirects to another page, but it doesn't show the success message before redirecting.
Controller:
public function register_ajax() {
//form validation rules
$this->form_validation->set_rules('org_name', 'Organisation Name',
'trim|required');
$this->form_validation->set_rules('email', 'Email',
'trim|required|valid_email|is_unique[new_church.email]',
array('is_unique' => "This email address is already registered
with this application.")
);
$this->form_validation->set_rules('password', 'Your Password',
'trim');
$this->form_validation->set_rules('c_password', 'Confirm Password',
'trim|required|matches[password]',
array(
'matches' => 'Password does not match'
)
);
if ($this->form_validation->run()) {
$this->registration_model->update_church(); //insert the data
into db
echo 1;
redirect(site_url('registration/payment'));
} else {
echo validation_errors();
}
}
Model:
public function update_church() {
$org_name = ucwords($this->input->post('org_name', TRUE));
$email = $this->input->post('email', TRUE);
$password = ucfirst($this->input->post('password', TRUE));
$c_password = ucfirst($this->input->post('c_password', TRUE));
$data = array (
'org_name' => $org_name,
'email' => $email,
'password' => $password,
'c_password' => $c_password,
);
$this->db->insert('new_church', $data);
//email admins
//$this->notify_admins($name, $email, $subject, $message);
}
JavaScript:
//Registration
$('#registration_form').submit(function(e) {
e.preventDefault();
var form_data = $(this).serialize();
$.ajax({
url: base_url + 'registration',
type: 'POST',
data: form_data,
success: function(msg) {
if (msg == 1) {
$('#status_msg').html('<div class="alert alert-success
text-center"> Success.</div>').fadeIn( 'fast' );
$('#registration_form')[0].reset(); //reset form fields
} else {
$('#status_msg').html('<div class="alert alert-danger
text-center">' + msg + '</div>').fadeIn( 'fast' ).delay(
30000 ).fadeOut( 'slow' );
}
}
});
});

I expect a success message to appear before redirecting to another page

what happened to your code is when your try to run the form validation it get always true because you set a condition where not executing if the result is true or false.
if ($this->form_validation->run() == TRUE) { //you should change it to this
$this->registration_model->update_church();
$data['success'] = 1;
} else { //if the form validation run false it will display the error.
$data['error'] = validation_errors();
}
echo json_encode($data);
And if you are going to send back a message to your AJAX code you should encode it first using JSON.
To display it.. do this.
if (msg.success == 1) {
$('#status_msg').html('<div class="alert alert-success
text-center"> Success.</div>');
$('#registration_form')[0].reset(); //reset form fields
setTimeout(function(){
window.location.replace("<?php echo base_url('registration/payment') ?>");
}, 3000); //set it to your time
} else if(msg.error){
$('#status_msg').html('<div class="alert alert-danger
text-center">' + msg.error + '</div>').fadeIn( 'fast' ).delay(
30000 ).fadeOut( 'slow' );
}
Hope that helps.Let me know the result.

Remove this line:
redirect(site_url('registration/payment'));
And in your ajax success function add this:
if (response == "1") {
// todo set timeout maybe and show a success message then redirect.
window.location.href = siteUrl+"registration/payment";
}
And just make sure to define siteUrl in your js file:
const siteUrl = "http://localhost/";

Ajax not refreshing contact form (PHP and Bootstrap 4)

I have this exact code on another website and it works flawlessly but for some reason on this website it won't work. It sends the email but it refreshes the page and forwards it to a contact.php with a message.
I have read through everything I could find. I have gone over the code and nothing is different. I even changed the html button type from submit to button. Nothing is working. The last thing I tried was to copy and paste the code from the working website to this site, and still it refreshes the page.
The ajax codes is being loaded after the jquery.

my javascript files are in the following order:

After echoing your json encoded array, it is important that you exit() the script else you won't end up with a proper JSON string on the client side;.

Bootstrap Alert Message not working

First - Im not an expert in PHP, but just know how to make some basic changes within contact form using PHP.
On this contact form when I filled in the required textfields and hit the submit button it redirects to the contact.php with a Contact form successfully submitted. Thank you, I will get back to you soon! message instead of displaying the message inside the <div class="messages"></div> on request-interpreter.html

You are echoing it (printing it) instead of returning the response, change it like this in your Contact.php
if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) &&
strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
$encoded = json_encode($responseArray);
header('Content-Type: application/json');
return $encoded;
}
// else just display the message
else {
return $responseArray['message'];
}

Custom AJAX form not working async

I have a contact from that uses PHP mailer that I have integrated into my Wordpress blog. The script sends emails no problem - the issue is that it does not work async so once the form is submitted I am taken to another page with the following text on it: {"message":"Your message was successfully submitted from PHP."}. The script works as expected when used outside of wordpress - I have no idea whats going on.

PHP, jQuery, Ajax, send HTML input fields with attachment field code not working

I am trying to send an email with an optional attachment when a button is clicked and display the results above the form fields. I have put together the following code, but it is not working (nothing happens when I click the submit button; would like to create a fiddle but JSFiddle does not accept PHP code):
Here is the HTML:
<div id="contactSubmitResult"></div>
<div id="contactSubmitResult"></div>
<div id="contactForm">
<div class="col1">
<label for="form_firstname">Firstname <span class="required">*</span></label>
<input type="text" id="form_firstname" name="form_firstname" value="" required />
</div>
<div class="col2">
<label for="form_lastname">Lastname <span class="required">*</span></label>

One problem: you forgot to put a html tag to
matchContactSubmitResult = "#contactSubmitResult";
add
<div id="contactSubmitResult"></div>
Here is snippet. I take the liberty to provide an alternative to success: function(){}, instead I used .done() and .fail() to provide in network or other problems. See here: jQuery.ajax() (I can't test your php code, but your jquery code works)
$(document).ready(function() {
matchFormFields = "#contactForm input[required], #contactForm textarea[required]";
matchContactSubmitResult = "#contactSubmitResult";
errorColor = 'red';
$("#form_send").click(function() {
var formIsValid = true;
// loop through each field and change border color to red for invalid fields
$(matchFormFields).each(function() {
$(this).css('border-color', '');
// check whether field is empty
if(!$.trim($(this).val())) {
$(this).css('border-color', errorColor);
formIsValid = false;
}
// check whether email is valid
var email_reg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
if($(this).attr("type") == "email" && !email_reg.test($.trim($(this).val()))) {
$(this).css('border-color', errorColor);
formIsValid = false;
}
});
// submit data to server if form field contents are valid

I've updated my code. There are no errors with the PHP code but when I
try to attach an attachment nothing happens. – John Sonderson
if so i think the problem is here.haven't tested but, this might help :)
var myfile=$('input[name=form_attachment]').val();
//apend the file
post_data.append('form_attachment', myfile);
