How to check if the email has already been used - php

I am made a form validation using PHP. If the error happens, the error msg will show around each input column. I would like to check if the email is used or not. So, I used error code to define if input email addr is used, then showing the error message for "The email has been used". However, the result becomes whatever I input, it only shows "The email has been used". Could some help me for this issue? Thanks!
<?php
require_once('./conn.php');
$errorMsgs = array('nickname'=>'', 'email'=>'', 'password'=>'');
if(isset($_POST['submit'])) {
if(empty($_POST['nickname'])) {
$errorMsgs['nickname'] = "Please enter your nickname";
}
$email = $_POST['email'];
$password = $_POST['password'];
// checking the email is valid or empty
if(empty($_POST['email'])) {
$errorMsgs['email'] = "Please enter your email";
} else {
if(!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$errorMsgs['email'] = "Please enter a valid email";
}
}
$errorCode = $conn->errno;
if($errorCode === 1062) {
$errorMsgs['email'] = "The email has been used";
}
// checking the password is valid or empty
if(empty($_POST['password'])) {
$errorMsgs['password'] = "Please enter your password";
} else {
if(!preg_match('/\w{8,}/', $password)) {
$errorMsgs['password'] = "Please enter at least 8 characters";
}
}
if(!array_filter($errorMsgs)) {
$sql = sprintf("INSERT INTO member (nickname, email, password) values ('%s', '%s', '%s')", $_POST['nickname'], $_POST['email'],$_POST['password']);
$result = $conn->query($sql);
if($result) {
header("Location: index.php");
}
}
}
?>

You have to check if the email exists in your user table.
something like this.
<?php
require_once('./conn.php');
$errorMsgs = array('nickname'=>'', 'email'=>'', 'password'=>'');
if(isset($_POST['submit'])) {
if(empty($_POST['nickname'])) {
$errorMsgs['nickname'] = "Please enter your nickname";
}
$email = $_POST['email'];
$password = $_POST['password'];
// checking the email is valid or empty
if(empty($_POST['email'])) {
$errorMsgs['email'] = "Please enter your email";
} else {
if(!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$errorMsgs['email'] = "Please enter a valid email";
}
else{
//you should use sql parameter binding
$email = $_POST['email'];
$checkDuplicate= $conn->query("SELECT email FROM user_table where email = '$email'");
if(!empty($checkDuplicate)) {
$errorMsgs['email'] = "The email has been used";
}
}
}
// checking the password is valid or empty
if(empty($_POST['password'])) {
$errorMsgs['password'] = "Please enter your password";
} else {
if(!preg_match('/\w{8,}/', $password)) {
$errorMsgs['password'] = "Please enter at least 8 characters";
}
}
if(empty($errorMsgs)) { //you need to check if there's any error
$sql = sprintf("INSERT INTO member (nickname, email, password) values ('%s', '%s', '%s')", $_POST['nickname'], $_POST['email'],$_POST['password']);
$result = $conn->query($sql);
if($result) {
header("Location: index.php");
}
}
}
?>

everytime i put in my email but not my username and password it says i need to put all three in even when one is already in
why is this happening and how do I fix it?
I thought about priorities but I don't know how or what to do that...
the rest of the code on the page is as follows
Please don't say anything about having the password as plain text.
Here is my test mysql.
My Test MYSQL
Here is my test website.
My Test Website
Here's your original code when run through a formatter. You should notice, as people have pointed out, it is indented like crazy and has a lot of nesting. You are also querying the database on each request, even if the data is invalid.
$username = $_POST['username'];
$password = $_POST['password'];
$email = $_POST['email'];
$valid = "You need to have a valid Email Address";
$sql = "SELECT * FROM accounts WHERE username=? and password=? and email=? LIMIT 1";
$stmtselect = $db->prepare($sql);
$result = $stmtselect->execute([$username, $password, $email]);
if (stripos($password, '')) {
echo 'You need to enter a Password';
} else {
if (stripos($username, '')) {
echo 'You need to enter a Username';
} else {
if (stripos($email, '')) {
echo 'You need to enter a Email Address';
} else {
if (!stripos($email, '#')) {
echo $valid;
} else {
if (!stripos($email, '.')) {
echo $valid;
} else {
if (!stripos($email, 'com')) {
echo $valid;
} else {
if ($result) {
$user = $stmtselect->fetch(PDO::FETCH_ASSOC);
if ($stmtselect->rowCount() > 0) {
$_SESSION['accounts'] = $user;
echo 'You have signed in successfully!';
} else {
echo 'Incorrect Username or Password or Email';
}
} else {
echo 'There were errors while connecting to database.';
}
}
}
}
}
}
}
Instead, here's a quick attempt at cleaning it up. The major changes are the switch to empty() checks, the usage of elseif, a better email address validator and moving the query to the final else clause.
$username = $_POST['username'];
$password = $_POST['password'];
$email = $_POST['email'];
if (empty($password)) {
echo 'You need to enter a Password';
} elseif (empty($username)) {
echo 'You need to enter a Username';
} elseif (empty($email)) {
echo 'You need to enter a Email Address';
} elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "You need to have a valid Email Address";
} else {
$sql = "SELECT * FROM accounts WHERE username=? and password=? and email=? LIMIT 1";
$stmtselect = $db->prepare($sql);
$result = $stmtselect->execute([$username, $password, $email]);
$user = $stmtselect->fetch(PDO::FETCH_ASSOC);
if ($stmtselect->rowCount() > 0) {
$_SESSION['accounts'] = $user;
echo 'You have signed in successfully!';
} else {
echo 'Incorrect Username or Password or Email';
}
}
EDIT
If your intention is to show multiple error messages and not just stop at the first one (as your original code does), then you can use multiple if blocks. Most people would collect the error messages in an array but I'll leave that up to you.
$isValid = true;
if (empty($password)) {
echo 'You need to enter a Password';
$isValid = false;
}
if (empty($username)) {
echo 'You need to enter a Username';
$isValid = false;
}
if (empty($email)) {
echo 'You need to enter a Email Address';
$isValid = false;
}elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "You need to have a valid Email Address";
$isValid = false;
}
if ($isValid) {
$sql = "SELECT * FROM accounts WHERE username=? and password=? and email=? LIMIT 1";
$stmtselect = $db->prepare($sql);
$result = $stmtselect->execute([$username, $password, $email]);
$user = $stmtselect->fetch(PDO::FETCH_ASSOC);
if ($stmtselect->rowCount() > 0) {
$_SESSION['accounts'] = $user;
echo 'You have signed in successfully!';
} else {
echo 'Incorrect Username or Password or Email';
}
}
EDIT
If you don't provide a method on the <form> it defaults to GET. Your code is expecting it to be POST, however. Change the form to <form method="post">.
EDIT
I'm not going to use any of your HTML and instead I'm going to just make a very simple form that POSTs to itself. This is a very common first task you learn when programming in any web language. This page, by itself, ignoring your database, styling and JS logic should work 100% by itself. Once you've proven that you can start enhancing it with sessions and then maybe AJAX. But start simple.
The form doesn't include normal settings like required or optimal types on fields intentionally because I'm just trying to keep it as simple as possible.
I did add in the errors array which removes the need for $isValid because we can now check to see if the error has anything inside of it.
Please try this code all by itself, and once you get how it works, then start modifying it, potentially asking new questions here if you really need to.
<?php
$errors = false;
$email = '';
$username = '';
$password = '';
if ('POST' === $_SERVER['REQUEST_METHOD']) {
$email = $_POST['email'];
$username = $_POST['username'];
$password = $_POST['password'];
$errors = [];
if (empty($password)) {
$errors[] = 'You need to enter a Password';
}
if (empty($username)) {
$errors[] = 'You need to enter a Username';
}
if (empty($email)) {
$errors[] = 'You need to enter a Email Address';
} elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$errors[] = "You need to have a valid Email Address";
}
}
if ($errors) {
echo '<pre>';
echo implode(PHP_EOL, $errors);
echo '</pre>';
}
?>
<form method="post">
<label>Email <input type="text" name="email" value="<?php echo htmlspecialchars($email); ?>"/></label><br/>

How to make login system with password_verify to work?

I am working on PHP/MYSQL register/login system for like a week and iam truly having issue with php password_hash and password_verify function...The register worked and the login with password_verify keeps failing and i do not understand why..Could somebody help out? i really am desperate.
Login part..what i am trying to achieve 1-its check if email is empty or not and if is valid email..2--its check if password is empty or not. 3-if both $email and $password are ok..it makes connection to db.. then a-it checks if the email exists in table users, if not it requires to register..b-if the user exists in db, then it verify if the $password is same as passsword in db...if it is valid password..it echoes "valid"..and if not valid password..it echoes "invalide email/password"...that is what i am trying to achieve...
Here i am posting the full code:

password(varchar, 255)

Tested the same scripts here and it worked.
I've received as answer "valide password / email", so this conditional statement "(password_verify($password, $result['password']))" returned true (line 51 within login.php).
Do you receive any error message or warning?

Echo in php is not showing up on the web page after form is submitted

I am using foundation 5 and php for this web page.
When I go to the web page and fill in all the spaces and press create account, none of the echos are showing up on the web page. The page just refreshes and just makes a new page like if I just reloaded the page. No text shows up and none of the function are working.

Your form has action='register.php' as its destination. When you do this, by pressing the Submit button, the page will jump to register.php before giving your error checking code any chance to fire.
I recommend you use
action='<?php echo $_SERVER['PHP_SELF']; ?>'
so that your Submit button keeps you on the same page, then when your error checking process passes, use:
header('Location: register.php');
Either that, or pass each of your POST variables to register.php where the error checking is carried out.
In this solution I have altered your code considerably but I use this logic all the time on my sites. I'll explain the code under it.
NOTE:
I did review your processing but did not test... Judging from the initial comments you are getting outdated information regarding programming. your mysql query code is outdated and depreciated and you should be making use of parameterised queries as pointed out in the comments by #Dave below this answer.
I suggest you go to youtube and search for pdo tutorials to learn modern methods of querying mysql. The provided code shows how to process forms through jQuery and a processing php file.

There are no form tags... the form processing is handled on register.php which is stored in a hidden input <input type="hidden" name="processRegistrationURL" value="register.php">
I have added id to each form and the submit button.
register.php
$getuser = $_POST['user'];
$getemail = $_POST['email'];
$getpass = $_POST['pass'];
$getconfirmpass = $_POST['confirmpass'];
if ($getuser) {
if ($getemail) {
if ($getpass){
if ($getconfirmpass) {
if ($getpass === $getconfirmpass) {
if (!filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
require ("connect.php");
$query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
$numrows = mysql_num_rows($query);
if ($numrows == 0) {
$query = mysql_query("SELECT * FROM users WHERE email='$getemail'");
$numrows = mysql_num_rows($query);
if ($numrows == 0) {
$password = md5(md5("kjfiufj".$getpass."Fj56fj"));
$date = date("F d, Y");
$code = md5(rand());
mysql_query("INSERT INTO users VALUES (
'', '$getuser', '$password', '$getemail', '0', '$code', '$date'
)");
$query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
$numrows = mysql_num_rows($query);
if ($numrows == 1) {
$site = "http://localhost/Projects/project";
$webmaster = "donotreply#askmanproducts.com";
$headers = "From: $webmaster";
$subject = "Activate Your Account";
$message = "Thanks For Registering. Click The Link Below To Activate Your Account.\n";
$message .= "$site/activate.php?user=$getuser&code=$code\n";
$message .= "You Must Activate Your Account To Login.";
if (mail($getemail, $subject, $message, $headers)) {
echo "You have been registered. You must activate your account from the activation link sent to <b>$getemail</b>";
$getuser = "";
$getemail = "";
}
else {
echo "2|An error has occurred. You activation email was not sent. Please refresh this page and try again. If this issue persists please contact administration.";
}
}
else {
echo "2|An error has occurred. Your account was not created. Please refresh this page and try again. If this issue persists please contact administration.";
}
}
else {
echo "1|There is already a user with that email.";
}
}
else {
echo "1|There is already a user with that username.";
}
mysql_close();
}
else {
echo "1|You must enter a valid email address to register.";
}
}
else {
echo "1|Your password do not match.";
}
}
else {
echo "1|You must confirm your password to register.";
}
}
else {
echo "1|You must enter your password to register.";
}
}
else {
echo "1|You must enter your email to register.";
}
}
else {
echo "1|You must enter your username to register.";
}
else {
echo "2|WHATEVER YOU WANT TO RENDER IN #showRegistrationResults";
}
When the button is clicked it fires the jQuery which in turn passes the form submission to register.php
You will notice in each echo there is a 1 or a 2 with a pipe. echo "1|You must enter your password to register.php"; The echo will return to the jQuery as data.
The jQuery then splits the data at the pipe (|). If result[0] == 1 the jQuery fires an alert leaving the form intact for corrections to be made. If result[0] == 2 the jQuery will replace the content of #showRegistrationResults which wraps the form (it will replace the form) with the data returned through the echo.
Review the echos on register.php. The first two replace the form as an error in processing has occurred. All other return an alert message.
You can toggle these as desired.
Improve your password security
You can improve your password security with the following code:
$hash_key = trim(file_get_contents('PATH-TO/key.dat'));
$password = hash_hmac('sha512', $getpass, $hash_key);
key.dat simply contains a key: for example: 72093OT7Yw6g0925T9Ly07G6y7WhI2v5
Hope this helps

registration page with php and mysql not working

Trying to create a registration page that adds new users to a database with php, i can't seem to get the information to add to the database, it is most likely something stupid that I have doing wrong or have missed out in my code.
Here is my code
<?php
session_start();

The If conditions you have written is always retrun false.
To Resolve this Please set the name attribute of submit button to formsubmitted like as follows
<input id="register_submit" name= "formsubmitted" type="submit" value="Sign up" />
Since the formsubmitted is not present inside the form the values is not set for $_POST['formsubmitted'], So the If part of your if statement is never executed.
Here is a similar script I often use, feel free to alter it at your discretion.
<?
if ($_POST['submit']){
$username = $_POST['username'];
$password = md5($_POST['password']);
$confirm = $_POST['confirm'];
$email = $_POST['email'];
if (!$username || !$password || !$confirm || !$email){
$response = "Please fill in all the boxes";
}else{
$check = mysql_num_rows(mysql_query("SELECT * FROM users WHERE username='$username'"));
if ($check != 0){
$response = "Username taken, Please choose an alternative";
}else{
$check = mysql_num_rows(mysql_query("SELECT * FROM users WHERE email='$email'"));
if ($check != 0){
$response = "This Email has already been registered";
}else{
mysql_query("INSERT INTO `users` (`id`, `username`, `password`, `email`) VALUES ('', '$username', '$password', '$email');");
$response = "Account Created";
}
}
}
}
echo "$response"; ?>

Register.php redirected to a blank page

I am trying to create a registration page in PHP with MYSQL . My index.php page has a form which I have to fill in , and upon registration , it is supposed to show the status of registration , whether it is successful or not , and whether confirmation link is being sent to the email. However , when I click register , it redirects to register.php where nothings is being shown - all i see is a blank page no matter what info i key in. Furthermore , upon checking my table (user) in database (users) , I realized that no data is being input. My database connection is correct since I have verified it and i suspect that the error is in register.php . can anyone take a look at it and guide me on what I might be doing wrong? Thanks in advance.
