Okay, I don't want to be rude, but all that code is a bit of a disaster. You're calling the on click function 3 different times, you're making ajax calls to the server on every form change and on submit. Then you're actually making two separate ajax calls for the actual submit function.
The code below is a lot more compact, only ever makes one ajax call and should work. I'll explain a bit before each code block
Your form add an id so that jQuery can use serialize in the ajax call
<form method="post" id="loginform" name="loginform" action="success.php">
<input type="email" class="homepage" name="user_email2" id="user_email2" placeholder="Email" maxlength="50" required />
<div class ="errormsg" id ="errormsg6"></div>
<input type="password" class="homepage" name="user_password2" id="user_password2" placeholder="Password" maxlength="20" required />
<div class ="errormsg" id ="errormsg7"></div>
<input type="submit" name="login" id="login" value="Submit">
<div class ="errormsglast" id ="errormsg8"></div>
</form>
validatelogin.php - This should only be one call to the server, do both functions in one, return the data as json rather than echoing single values, that way you get an object back that you can parse in your jQuery code.
<?php
if (session_status() == PHP_SESSION_NONE) {
session_start();
}
if(isset($_POST['user_email2'], $_POST['user_password2'] )) {
$user_password2 = $_POST['user_password2'];
$user_email2 = strtolower($_POST['user_email2']);
if($user_email2 != "example@example.com") {
$data['email_check'] = 'false';
} else {
$data['email_check'] = 'true';
}
$data = array;
if($user_email2!="example@example.com" && $user_password2!="12345678") {
$data['password_check'] = 'false';
} else {
$data['password_check'] = 'true';
}
}
print(json_encode($data));
jQuery - I am not really sure why you're calling all these functions on blur and the multiple on clicks. Just do it in the one on click, call validate email, if that passes you move on to validate password and if that passes it makes the ajax call to actually check the details against the server.
Also avoid variable names like item5, errormsg6, to another developer that means nothing, and it won't to you in 6 months either. And don't tell people which element was wrong, ie "Incorrect password" just for security, just tell them their login details are wrong.
$(document).ready(function() {
/* ----------------- Login Validations Global Variables ----------------- */
var user_email2 = "";
var user_emailajax2 = "";
var user_password2 = "";
var user_passwordajax2 = "";
var emailformat = new RegExp(/^[+a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,4}$/i);
/* ----------------- Define Validate Email */
var validate_email_login = function() {
var email = $("#user_email2").val().toLowerCase();
var errors = [];
if (email.length < 6 || email.length > 50) {
errors.push("Email : 6 - 50 Characters<br>");
}
if (!emailformat.test(email)) {
errors.push("Wrong Email Format");
}
if( errors.length > 0 ) {
$("#errormsg6").html(errors);
return false;
}
$("#errormsg6").html();
validate_password_login();
}
/* ----------------- Define Validate Password */
var validate_password_login = function() {
var item6 = $("#user_password2").val();
if (item6.length < 8 || item6.length > 20) {
$("#errormsg7").html("Password : 8-20 Characters");
return false;
}
$("#errormsg7").html("");
submitForm();
}
var submitForm = function() {
$.ajax({
type: 'POST',
url: 'validatelogin.php',
dataType: "json",
data: $("#loginform").serialize(),
success: function(msg) {
if(msg.email_check == 'true' && msg.password_check == 'true') {
//do whatever it is you want to do on correct login here
} else {
$("#errormsg6").html("Your login details are incorrect, please check and try again");
}
}
});
}
/* ----------------- Stop on Submit */
$("#login").on('click', function() {
errors = [];
if(validate_email_login() == true) {
alert("hi");
}
});
});
