This is my page. I have no idea what happened. It is so frustrating because it is so simple.
When I try to extract a value if my input fields give nothing. Even if I warn before AJAX, he does not write anything. I copied the input that was under mine, and it was exactly the same.
What's wrong?
registration.php:
<?php
if(isset($_POST["php_username"]) && isset($_POST["php_password"]) && isset($_POST["php_password2"]) && isset($_POST["php_email"])){
$error = "";
if(strlen($_POST["php_username"]) < 8){
$error = $error."Username has to be at least 8 characters.<br>";
}
if(strlen($_POST["php_password"]) < 8){
$error = $error."password has to be at least 8 characters.<br>";
}
if(strlen($_POST["php_username"]) > 16){
$error = $error."Username can't be more than 16 characters.<br>";
}
if(strlen($_POST["php_password"]) < 16){
$error = $error."Password can't be more than 16 characters.<br>";
}
if(strcmp($_POST["php_password"],$_POST["php_password2"])){
$error = $error."Password confirmation falied.<br>";
}
echo($error);
}else{
echo('
