I posted part of the below code to another question for a problem I had,and found the solution.I can register,login and logout from my android device,which is good. However,now I am getting something strange. I added an extra functionality,so as to validate that both $user_pass and $confirm password variables are equal(comparing strings). However I always get a json message "Passwords don't match" from this.
if($userPass!==$confirmPass){
$don = array('result' =>"fail","message"=>"Passwords don't match");
}
The whole code is the following.
<?php
session_start();
require "init.php";
header('Content-type: application/json');
$email = $_POST['email'];
$user_name = $_POST['user_name'];
$user_pass = $_POST['user_pass'];
$passwordEncrypted = sha1($user_pass);
$confirmPass = $_POST['confirm_pass'];
$confPasswordEncrypted = sha1($confirmPass);
$msg = "Congratulations. You are now registered to the most amazing app ever!";
if(!filter_var($email, FILTER_VALIDATE_EMAIL)){
$don = array('result' =>"fail","message"=>"Please enter a valid email");
}
if($email && $user_name && $user_pass && $confirmPass && filter_var($email, FILTER_VALIDATE_EMAIL)){
$sql_query = "select * from user_info WHERE email ='".mysqli_real_escape_string($con, $email)."' or user_name
='".mysqli_real_escape_string($con, $user_name)."'";
$result = mysqli_query($con, $sql_query);
$results = mysqli_num_rows($result);
if ($results){
$don = array('result' =>"fail","message"=>"Email or username exists.");
}else{
$sql_query = "insert into user_info values('$email','$user_name','$passwordEncrypted','$confPasswordEncrypted');";
if(mysqli_query($con,$sql_query)){
$don = array('result' =>"success","message"=>"Successfully registered!Well done");
//mail($email,"Well done",$msg);
$_SESSION['email']=$row['email'];
}
}
} if(!$email){
$don = array('result' =>"fail","message"=>"Please enter your email");
}else if(!$user_name){
$don = array('result' =>"fail","message"=>"Please enter your username");
}else if(!$user_pass){
$don = array('result' =>"fail","message"=>"Please enter a password");
//The last if statement causes the problem.
}else if($userPass!==$confirmPass){
$don = array('result' =>"fail","message"=>"Passwords don't match");
}
echo json_encode($don);
?>
