registration page with php and mysql not working - php

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"; ?>

How to check if the email has already been used

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");
}
}
}
?>

Any help would be appreciated!
You're setting the validation error to the $email_err variable, but you're not doing anything with that variable after that.
But more importantly, the filter_var() call will never be hit. You have it in the block that checks for any of $name $mail $gender $messsage are empty. So the only way to get your code to do an email validation would be if someone entered an email address, but left gender blank.
You need to move the filter_var() call out of that block:
if(empty($name) || empty($mail) || empty($gender)|| empty($message)) {
if(empty($name)){
echo'<div class="error">*Dear User fill the Name field properly</div>';
}
if(empty($mail)){
echo'<div class="error">*Dear User fill the Email field properly</div>';
}
if(empty($gender)){
echo'<div class="error">*Dear User please select your gender</div>';
}
if(empty($message)){
echo'<div class="error">*Dear User please Leave your Message</div>';
}
}
elseif(!filter_var($mail, FILTER_VALIDATE_EMAIL)){
echo'<div class="error">*valid Email is required</div>';
}
else {
$query = mysql_query("INSERT INTO users(`name`, `mail`, `gender`, `message`) VALUES('".$name."','".$mail."','".$gender."','".$message."')");
if($query) {
echo '<div class="success">Congratulations You Are Registered Successfully</div>';
echo 'View Records';
}
else {
echo 'not';
}
}
When I write validation code such as this I try to avoid using conditionals that check so many things at once. Instead, validate each input in turn and abort if that is not valid; returning an error to the user at that point. Then you could move all of this validation to a single sub-routine. In this routine, if any validation checks fail - it returns immediately with an error. Only if your sub-routine makes it to the end would a user be created. And it prevents one from checking a variable $mail and then later validating it after it's already passed your truth check.

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.

}
}
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

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.

Using mysql_query in PHP to show the user name is not working

I am currently trying to create a registration form, and I have the form itself working and people can create user's in my database, but when they sign up and it redirects them to the admin.php.
The name they used to create an account doesn't show up, down by row user name. It should say "Welcome, user_name, you are now logged in!"
I just can't get the name to show up but everything else works!

$_SESSION['user_id'] = $_COOKIE['user_id'];
$_SESSION['is_admin'] = $_COOKIE['is_admin'];
}
if( $_SESSION['logged_in'] != true ){
//not logged in! send them back to the form]
header('location:login.php');
}
//extract the data for the logged in user, so we can use it on all page
$user_id = $_SESSION['name'];
$query_user = "SELECT * FROM users
WHERE name = $user_id
LIMIT 1";
$result_user = mysql_query($query_user);
$row_user = mysql_fetch_array($result_user);
//this going to be a handy variable to have throughout all pages
$user_id = $row_user['user_id'];

What do I need to fix?
You should check what the error is:
if (!$result_user) {
die('MySQL Error: '.mysql_error());
}
Call session_start() at the top of each of your pages.
And ensure session's values are returned correctly:
print_r($_SESSION);
In admin.php, this query is failing:
$query_user = "SELECT * FROM users WHERE name = $user_id LIMIT 1";
Maybe $user_id is empty, or it needs to be quoted ('$user_id').
In any case you should be checking the result of the query to make sure it was successful:
$user_id = $_SESSION['name'];
$query_user = "SELECT * FROM users
WHERE name = $user_id
LIMIT 1";
$result_user = mysql_query($query_user);
if (!$result_user) {
die('Query failed: ' . mysql_error());
}
mysql_query() only returns a resource result on success. On failure, it returns (bool)FALSE which cannot be passed to any mysql_fetch_* functions.
The same is the case for the error in login.php.
You don't seem to be showing the code that runs upon login, my guess is you are not assigning the right variables to the session.
