Ajax not refreshing - php

I am trying to setup a register box to create new account. I am trying to load the html form through ajax and passing data to a php file.
I want to make the div which is containing the form to reload every time when the "register" button is hit to get the result from the php script and display it out. However, my code seems not working properly (The ajax handling div will not load the form ). Below are my codes:
Register.php:
<?php
session_start();
$email = $_POST['email'];
$email = mysql_real_escape_string($email);
$pwd = $_POST['pwd'];
$repwd = $_POST['repwd'];
$lname = $_POST['lname'];
$fname = $_POST['fname'];
$isValidEmail = 1;
if (substr_count($email, '#') != 1){
$isValidEmail = 0;
}
if($pwd != $repwd){ //check if password and re-entered passwords are the same
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Password and Re-entered Password are different.';
} else if( strlen($pwd) < 6 || strlen($pwd) > 64 ) { //check if password is 6 - 64 characters
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Password must be 6 - 64 characters.';
} else if( strlen($email) > 255) { //check if the email is too long
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Email exceeded maximum length.';
} else if ($isValidEmail != 1){
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Invalid Email.';
} else if (ctype_space($lname) || ctype_space($fname)){
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Please enter your name.';
} else {
if ($mysqli = new mysqli("localhost", "root", "", "my_db")){
$stmt = $mysqli->prepare("SELECT email FROM users WHERE email = ?");
$stmt->bind_param('s',$email);
$stmt->execute();
$stmt->bind_result($result);
$stmt->fetch();
$stmt->close();
if ($result == $email) { //check if the input email exists in the database, duplicated user
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Email '.$email.' is already used.';
} else {
$hash = hash('sha256', $pwd);
function createSalt()
{
$string = md5(uniqid(rand(), true));
return substr($string, 0, 3);
}
$salt = createSalt();
$hash = hash('sha256', $salt . $hash);
$stmt = $mysqli->prepare("INSERT INTO users ( email, lastName, firstName, password, salt )
VALUES ( ? , ?, ?, ? ,? )");
$stmt->bind_param('sssss', $email, $lname, $fname, $hash, $salt);
if ($stmt->execute()){
$_SESSION['message'] = 'Registered.';
} else {
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Database query error occured.';
}
$stmt->close();
}
} else {
$_SESSION['error'] = 1;
$_SESSION['message'] = 'Error connecting to the database.';
}
}
header("Location: Home.php");
$mysqli->close();
?>
ajax.js:
$(document).ready(function() {
$('#submit_register').click(function(){
$('#register_form').submit( function(){
$.ajax({
type: 'POST',
url : 'Register.php',
data: $('#register_form').serialize(),
success: function () {
var myURL = "Register_form.php#register_div";
$('#ajaxHandle').load(myURL);
return false;
},
});
});
});

<input id="submit_register" type="submit" value="Register" /><br>
</div>
</form>
</div>
</div>
</body>
</html>
I am doing something wrong? Any advice will be appreciated. Thank you very much!

I think I figured it out. I have put the refreshing jquery code in the wrong place. It worked when I put it within the .submit scope:
$(document).ready(function() {
$('#submit_register').click(function(){
$('#register_form').submit( function(){
$.post(
'Register.php',
$(this).serialize()
);
var myURL = "Register_form.php#register_div";
$('#ajaxHandle').load(myURL);
return false;
});
});
});

Login form validation using php and ajax

I have a login form that has two inputs email and password. If a user enters incorrect credentials, I have to show them the error. I have done form validation in PHP, so I need to send data from the form and get a response message without refreshing the page. I'm new to ajax, so I don't know how to do it
login.php
<form action="register.php" method="POST" autocomplete="off">
<h1 class="card-title display-4 mt-4 mb-5 text-center">Login</h1>
<div class="form-group">
<input type="email" class="form-control" id="email" placeholder="Email" name="email" />
<div class="email-status"></div>
</div>
<div class="form-group">
<input type="password" class="form-control" id="password" placeholder="Password" name="password" />
<div class="password-status"></div>
</div>
<p class="card-text text-center">Forgot your password?</p>
<span class="d-flex justify-content-center">
<button type="submit" class="btn btn-primary mb-4 w-50" style="border-radius: 20px;" name="login_btn" id="login_btn">Login</button>
</span>
<div class="success"></div>
</form>
<script>
$(document).ready(function() {
$("#login_btn").click(function() {
var email = $("#email").val();
var password = $("#password").val();
$.ajax({
url: 'register.php',
type: 'post',
data: {
email: email,
password: password
},
success: function(response) {
var emailstatus = "";
var passwordstatus = "";
var success = "";
if (response == 1) {
emailstatus = "required";
$(".email-status").text(emailstatus);
} else if (response == 2) {
emailstatus = "invalid";
$(".email-status").text(emailstatus);
} else if (response == 3) {
emailstatus = "match";
$(".email-status").text(emailstatus);
} else if (response == 4) {
passwordstatus = "required";
$(".password-status").text(passwordstatus);
} else if (response == 5) {
passwordstatus = "match";
$(".password-status").text(passwordstatus);
} else {
success = "sometihg went wrong";
$(".success").text(success);
}
}
});
});
});
</script>
register.php for form validation
if (isset($_POST['login_btn'])) {
$email = mysqli_real_escape_string($conn, $_POST['email']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
$new_password = md5($password);
$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '$email' OR password = '$new_password' LIMIT 1");
$row = mysqli_fetch_assoc($result);
//EMAIL
if (empty($email)) {
$email_status = "Email is required";
echo 1;
} elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$email_status = "Enter valid Email ID";
echo 2;
} elseif ($row['email'] != $email) {
$email_status = "Email doesn't exist";
echo 3;
}
//PASSWORD
elseif (empty($password)) {
$password_status = "Password is required";
echo 4;
} elseif ($row['password'] != $new_password) {
$password_status = "Password doesn't match";
echo 5;
} else {
$query = "SELECT * FROM users WHERE email = '$email' AND password = '$new_password'";
$results = mysqli_query($conn, $query);
if (mysqli_num_rows($results) == 1) {
$rows = mysqli_fetch_array($results);
$_SESSION['username'] = $rows['username'];
$_SESSION['success'] = "You are now logged in";
if (isset($_SESSION['login_redirect'])) {
header("Location: " . $_SESSION["login_redirect"]);
unset($_SESSION["login_redirect"]);
} else if (isset($_SESSION['url'])) {
$url = $_SESSION['url'];
header("Location: $url");
} else {
header("Location: homepage.php");
}
exit;
} else {
$success = "Something went wrong";
echo 6;
}
}
}
If I run the above code, the page gets refresh and I'm not getting any response or validation messages
You have to prevent auto form submit. add an Id or a class to your form element and add this code
Inside of document ready
$("#form-id").submit(function(e){
e.preventDefault();
});
And in form element add an Id
<form action="register.php" id='form-id' method="POST" autocomplete="off">
Replace your data object of ajax as follows and your current code will work:
data: {
email: email,
password: password,
login_btn: true
}
You are checking isset of login_btn value which was not pass through the ajax.

ajax - Error with execution of php script and data validation - how to solve?

I made a Signup form for my website. Then, I created PHP script which validates and insert user data into the database and it works perfectly. Then, I tried to make AJAX validation which will apply styles on the HTML elements and show error messages if an error occurs. I followed some tutorials, read answers and solutions from Stack Overflow, but for some reason, it doesn't work. When I click Submit button, nothing happens.
This is my code:
HTML
<form id="signupForm" action="./includes/signup.script.php" method="POST">
<div id="emptyFields" class="inputErrorMessage">
<p>You must fill all fields!</p>
</div>
<div class="form-group">
<label for="formGroupExampleInput">First name</label>
<input id="firstName" type="text" name="firstName" class="form-control formFieldBO">
<div id="firstNameChar" class="inputErrorMessage">
<p>First name must contain letters only.</p>
</div>
<div id="firstNameLength" class="inputErrorMessage">
<p>First name must contain at least 2 characters.</p>
</div>
</div>
<div class="form-group">
<label for="formGroupExampleInput">Last name</label>
<input id="lastName" type="text" name="lastName" class="form-control formFieldBO">
<div id="lastNameChar" class="inputErrorMessage">
<p>Last name must contain letters only.</p>
</div>
<div id="lastNameLenght" class="inputErrorMessage">
<p>Last name must contain at least 2 characters.</p>
</div>
</div>
<div class="form-group">
<label for="formGroupExampleInput">E-mail</label>
<input id="email" type="email" name="email" class="form-control formFieldBO">
<div id="emailValid" class="inputErrorMessage">
<p>Please, enter e-mail in valid form.</p>
</div>
</div>
<div class="form-group">
<label for="formGroupExampleInput">Password</label>
<input id="password" type="password" name="password" class="form-control formFieldBO">
<div id="passwordChar" class="inputErrorMessage">
<p>Password must contain at least 6 characters.</p>
</div>
</div>
<div class="form-group">
<label for="formGroupExampleInput">Confirm Password</label>
<input id="confirmPassword" type="password" name="confirmPassword" class="form-control formFieldBO">
<div id="passwordConfirm" class="inputErrorMessage">
<p>Confirmed password does not match.</p>
</div>
</div>
<div class="form-group">
<label for="formGroupExampleInput">Country</label>
<select id="inputState" name="country" class="form-control formFieldBO">
<option value="" disabled selected>Select country</option>
<option value="AFG">Afghanistan</option>
</select>
<div id="countryChoose" class="inputErrorMessage">

Put all the JQuery validation codes under this function .
Change button type="submit" to input type="submit" .
Let's see if this can solve your problems .

Using JQuery AJAX to submit a form to PHP, return data is empty

When I run this code below, the "data" returned is an empty string "[]". (At least viewed through the Chrome Console Viewer)
If I comment out the "event.preventDefault();" line in the JS I get a page reload, as expected, and a JSON string with results that passes JSONLint. I know the PHP is working as I am getting new inserts into the mySQL database and the return values make sense.
Everything seems to run correctly even with "data" is returned empty... (i.e. I am getting the console.log of FIRST first and SECOND second followed by the empty string.) I just can't get the returned "data" values in the JS context.
I'm kinda new to web development, not to programming... but does anyone spot a rookie mistake? I have read over about 12 similar questions and tried many things, but nothing is helping...
Thanks in advance.

$('form').submit(function(event) {

The PHP code checks whether $_POST['submit'] is set before doing anything with the form data, but you never set that in formData. Try:
var formData = {
'firstName': $('input[name=firstName]').val(),
'lastName': $('input[name=lastName]').val(),
'email': $('input[name=email]').val(),
'password': $('input[name=password]').val(),
'submit': 'on'
};

PDO Register and Login Password Matching

Okay.. so to start off I only have Php 5.3 so I can't use bcrypt, I am not familiar with salt but an completely willing to do it if someone can help me out. I also would like to know if this script is bad or good for sql injections. My biggest problems is when I use something like crypt and try to get my passwords to match, it won't. I've been working on this for days and can't seem to find the right solution to my problem. the code is not done yet, but its able to run. I'm just doing this on wamp so i dunno if thats a problem? but i cant imagine it is.

I REALLLLLYY need to get it so it is secure for my server on launch and can login a user safely.
With PHP version 5.3 you can and should use BCrypt.
For PHP version 5.5 and higher it is recommended to use the new password functions password_hash() and password_verify():
// Hash a new password for storing in the database.
// The function automatically generates a cryptographically safe salt.
$hashToStoreInDb = password_hash($password, PASSWORD_BCRYPT);
// Check if the hash of the entered login password, matches the stored hash.
// The salt and the cost factor will be extracted from $existingHashFromDb.
$isPasswordCorrect = password_verify($password, $existingHashFromDb);
For PHP version 5.3.7 and higher there exists a compatibility pack, so you can use the functions above in exactly the same way.
For PHP versions earlier than 5.3.7 you could use the compatibility pack and change the crypt parameter from "$2y$%02d$" to "$2a$%02d$", this generates a BCrypt hash as well. It is the best you can do with older versions, the hashes will be compatible when you update to a newer PHP version.
When you want to verify the password, you cannot do this in the SQL statement directly. In a first step you have to get the stored password-hash from the database (with the username), then you can use this hash in the function password_verify(). The password_verify() function needs to extract the salt from the stored hash.
