Also:
- Add meta charset to the form page

or HTML5
<meta charset='utf-8'>

I am new to php and working on a hangman game. I have a home.php that takes you to the homepage and their is a login form that the user must submit a username and a password. If the username and password match with the one I have set, it will redirect to hangman.php. I want some advice if the way I have written the script is correct or not. Also, I am getting a 500 error after the user logs in. I don't know why. I will paste the code down below.
Update: I have added the code for hangman.php
home.php
<?php
// starting a new session
session_start();
if(isset($_POST['uname'], $_POST['psw'])){
$uname= "my_admin";
$psw = "password";
if($_POST['uname'] == $uname && $_POST['psw'] == $psw) {
$_SESSION["uname"] = "my_admin";
$_SESSION["psw"] = "password";
# array holds errors
$errors = array();
# validation starts here
if(empty($_POST['uname'])){
$errors['uname1'] = "Your name cannot be empty";
}
# check strlength
if(strlen($_POST['uname']) < 6){
$errors['uname2'] = "Must be longer than 6 characters";
}
# check username
if ($_POST['uname'] !== "my_admin"){
$errors['uname3'] = "You are not the admin";
}
if($_POST['uname'] == "my_admin" && $_POST['psw'] == "password"){

if(strlen($_POST['psw']) < 6){
$errors['psw2'] = "Must be longer than 6 characters";

if($_POST['psw'] !== "password"){
$errors['ps3'] = "AH AH AH thats not it";
}else{
header('Location:hangman.php');
exit();
}
if(count($errors) == 0){
# redirect to the game page

Oops, you don't close that else if, so your INSERT is always skipped.
The next problem
One part of the code that looks dodgy are these lines:
$datetime = date('Y-m-d G:i:s');
//...
$query = "INSERT INTO job (User_UserID,Problem_ProblemID,Status_StatusID,Room_RoomID,Description,Date_Time)
VALUES({$userid},{$problem},{$status},{$room},'{$text}',{$dateTime})";
^^^^^^^^^^^
Your $dateTime will be something like 2016-12-09 11:43:42, so the SQL statement will be:
INSERT INTO job (...) VALUES(..., 'This is my text', 2016-12-09 11:43:42)
This is a syntax error. Note that your $text field has quotes around it to keep it as a single element, but your date does not. Using '{$dateTime}' will fix this problem, although there is no guarantee that there is no other issue...
When the user submits a form, the PHP will check to see if the $post was empty, if so, it will set an $error_message variable; thus database INSERT query will not execute. I then attempt to show the error message further on in the code, however it will not display. I have been trying to figure this out for hours and I still cannot find the solution. The funny thing is, this used to work, however I must have implemented something in this file which is preventing the code to execute correctly.
Why is my error message not echoing to the screen (last few lines of code show attempt to echo the error_message)?

You probably have a typo on the input HTML field. You can use:
if (isset($_POST[$field])) {
on validate_presences() function to be sure that the value exists.
When you try to do trim($_POST[$field]); you assume, the field exists in the $_POST array - for visible it does not in this case. You could move the trim to has_presence()
function has_presence($value) {
return isset($value) && trim($value) !== "";
}
function validate_presences($required_fields) {
global $errors;
foreach($required_fields as $field) {
if (!has_presence($value)) {
$errors[$field] = fieldname_as_text($field) . " can't be blank";
}
}
}
Now when you will only have the trim if the variable exists.
Okay, marking the radio check button makes it work now. Thanks for all your inputs guys. It has helped me a great deal.
I have a problem with php & mysql, insert to database using utf-8.
first file:
addsite:
<?php
include 'header.php';
if(isset($data)) {
foreach($_POST as $key => $value) {
$posts[$key] = filter($value);
}
if(isset($posts['type'])){
if($posts['url'] == "http://" || $posts['url'] == ""){
$error = "Add your page link!";
}else if($posts['title'] == ""){
$error = "Add your page title!";
}else if(!preg_match("/\bhttp\b/i", $posts['url'])){
$error = "URL must contain http://";
}else if(!preg_match('|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i', $posts['url'])){
$error = "Please do not use special characters in the url.<";
}else{
include "plugins/" . $posts['type'] . "/addsite.php";
}
}
