On this site I found a lot of cool examples of PHP OOP.
Maybe you know where to find complete examples?
Guest books, registration forms, blog...
When I look at the full model is much easier to understand OOP PHP.
As different classes interacting with each other, exchange data
How to use the generic class for sending data to the database
Thanks
Following is the sample code:
class.php

* Create variables for credentials to MySQL database
* The variables have been declared as private. This
* means that they will only be available with the
* Database class
*/
private $db_host = "localhost"; // Change as required
private $db_user = "root"; // Change as required
private $db_pass = ""; // Change as required
private $db_name = ""; // Change as required
/*
* Extra variables that are required by other function such as boolean con variable
*/
private $con = false; // Check to see if the connection is active
private $result = array(); // Any results from a query will be stored here
// Function to make connection to database
public function connect(){
if(!$this->con){
$myconn = #mysql_connect($this->db_host,$this->db_user,$this->db_pass); // mysql_connect() with variables defined at the start of Database class
if($myconn){
$seldb = #mysql_select_db($this->db_name,$myconn); // Credentials have been pass through mysql_connect() now select the database
if($seldb){

i really enjoyed this book when i was getting rolling with php

i have this database which contains tables one for questions and the other for answers and i need to use php to update the question and answers but when i do query to select the question and answers i get four questions and four answers or one question and one answer here's my tables structure

Well the problem is in your while cycles. The code is not very clean, but you are printing for every question 4 times the same answer (last found in your mysql database) and not all the answers. Can you try this, I am not sure if there is not a typo because I can not run the code.

I have implemented a functioning login and registration into a website template, but i am stuck on how to update other users details within the database using a form style basis?
For example is changing what group their in for the permissions, then a mod being able to give a 24 hour time out for chat/comments to standard users and so on.
Below is a very basic what i am talking about which iv done using the existing code just a different form, and its getting the username thats entered there that needs to be the 'id' for which row is edited?
I realise my code doesnt have what's needed but if anyone could point me in the right direction id much appreciate it.
<?php
require 'core/init.php';
include 'includes/overall/header.php';
if(!$user->hasPermission('admin')) {
Redirect::to ('index.php');
}
if(Input::exists()) {
if(Token::check(Input::get('token'))) {
$validate = new Validate();
$validation = $validate->check($_POST, array(
'username' => array(
'required' => true)
));
if($validation->passed()) {
try {
$user->update(array(
'grouptest' => Input::get('group')
));
} catch(Exception $e) {
die($e->getMessage());
}
Session::flash('home', 'Your Name has been updated succssfully!.');
Redirect::to('useraccount.php');
} else {
foreach($validate->errors() as $error) {
echo $error, '<br>';
}
}
}
}
?>
<form method="post" action="">
<label for="username">Change user:</label>
<input type="text" name="username" id="username" value=""/>
<label for="group"> to group:</label>
<select name="group" id="group">
<option value="1">Standard user</option>
<option value="2">Moderator</option>
<option value="3">Administrator</option>
</select>
<input type="submit" value="Update">
</form>
i sorted it thanks. here is the whole rewrite of the code just for this.
It is basic but made it on its own.
<?php
error_reporting(E_ALL);
require 'connect.php';
require 'security.php';
$records =array();
if(!empty($_POST)){

$perms = trim($_POST['perms']);
if(!empty($username) && !empty($perms)){
$update = $db->query("UPDATE users2 SET perms = '$perms' WHERE username = '$username'");
if($update){
echo 'success';
header('location: updatedb.php');
die();
} else {
echo 'failed';
}
}
}
}
if($results = $db->query("SELECT * FROM users2")){
if($results->num_rows){
while($row = $results->fetch_object()){
$records[] = $row;

$results->free();

When I was trying to delete first row of this table, it won't delete, rather it shows me error that kindly put details in text box which I have used while Adding New Category.
IMAGE : https://dl.dropboxusercontent.com/u/88831139/1.jpg
Except Row 1, query works on each row. If I click delete for ID 2, 3 or 4, all works fine, except for Row 1. It does not work with ID=1.
Kindly do suggest me what to do.
NOTE: I have used session to keep the values in variables.
I am not deleting row i just update the status of that to keep it in record here is Code :
to ADD CATEGORY :
if(isset($_POST['category']))
{ $cat = $_POST['category'];
$validate_category = "SELECT * FROM Category WHERE CategoryName ='$cat'";
$result = mysql_query($validate_category);
$count = mysql_num_rows($result);
if(empty($cat))
{
session_start();
$msg = 'kindly Put Details completely';
$_SESSION['status'] = $msg;
$_SESSION['color'] = 'red';
header("location:../category.php");
}
else if($count==1)
{
session_start();
$msg = 'Category Already Exist !!! Kindly Choose any Other Category';
$_SESSION['status'] = $msg;
$_SESSION['color'] = 'red';
header("location:../category.php");
}
else{
$query = "INSERT INTO Category(CategoryName) values ('$cat')";
mysql_query($query);
session_start();
$msg = 'New Category has been Created';
$_SESSION['status'] = $msg;
$_SESSION['color'] = 'green';

You could use AJAX for it. I see you use jQuery, so a simple get or post-request should do the trick.
Here: jQuery .get you will find some examples on how to do this. After the item has been added to the database you can use jQuery to add it to your select-box.
The app.php is getting the post value from another page. And that value used for query purposes. That post value is used to edit multiple values in app.php. I post again the multiple values to edit.php to update the records that shows in app.php. What I want is when I back into app.php using <meta http-equiv="refresh" content="0;app.php" /> or <script type="text/javascript">window.history.go(-1);</script> the value in app.php should get the new or the updated value from edit.php. I'm not good using sessions. Help please?
app.php
$mysqli = new mysqli("localhost", "root", "", "app");
ob_start();
session_start()
<form name="myform" method="post" action="edit.php"/>
if (isset($_POST['submit'])) {
//unset the session value
$_SESSION['content'] = '';
$drop = $_POST['drop_1'];
$tier_two = $_POST['tier_two'];
$where = "WHERE a.app_cn='$drop' AND a.app_plan_no='$tier_two'";
$result1 = $mysqli->query(" query ");
<table>
while ($row = $result1->fetch_assoc()) {
<td><input name="checkbox[]" type="checkbox" id="checkbox[]" value="' . $row['id'] . '"'.($row['pr'] == ""?"disabled ":"").' style="cursor:pointer;" class="checkbox"></td>
}
</table>
$sPageContent = ob_get_clean();
$_SESSION['content'] = $sPageContent;
echo $_SESSION['content'];
} else {
if (isset($_SESSION['content'])) {
echo $_SESSION['content'];
}
}
</form>
Edit.php
<?php
$mysqli = new mysqli("localhost", "root", "", "app");

$counter=$_POST['counter'];
$pr=$_POST['pr'];
$pr_qty=$_POST['pr_qty'];
$N = count($counter);
for($i=0; $i < $N; $i++)
{
$result = $mysqli->query("UPDATE purchase_request SET pr='$pr[$i]', total_quantity='$pr_qty[$i]' where counter='$counter[$i]'");
}
echo'<meta http-equiv="refresh" content="0;app.php" />';
}
?>
<form class="form-horizontal" action="" method="post">

$id=$_POST['checkbox'];
$N = count($id);

$result1 = $mysqli->query("
