Properties

You can choose type of file to be uploaded.
For every type of file to be uploaded, you can choose biggest size of file which is allowed.
Day, month and year choices are assigned as folder.( day/month/year or year/day depends on your wish.)

Usage

1- Write type of file and the biggest size of file as byte format to $file_types variable.For example, for jpep type “image/jpeg” => 30000. For more mime type, you can visit:

http://www.w3schools.com/media/media_mimeref.asp

2- Write the file to be uploaded to $path variable. For year “%year%”    is used, for month  “ %month% ” for day %day% are also used.As a example, your file name is af and for archiving the file monthly,                 “af %month%” is used.

3- To rename your file, choice of $new_name must be true otherwise choice must be changed as false.

4- $path_right is used for new file to be created.

5- Include “af_fileupload_class.php” file to the file to be used.

6- Create a new class, $a= new af_upload();

7- Send received file to upload function,

$a->upload ($_FILES ['uploadedfile']);

af_fileupload_class.php

find this in php.ini

and change with

error_reporting = E_ALL & ~E_NOTICE

than restart apache.

I will use adjacency list model  because it is more understandable than tree traversal. In tree traversal model , insterting and editing categories is unclear , also this model is for bigger database.  However, i advice you to look  up Tree traversal’s logic, i liked it .

Let’s start with creating database;

CREATE TABLE IF NOT EXISTS `category` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(128) NOT NULL,
  `top_id` int(11) NOT NULL,
  PRIMARY KEY  (`id`),
  KEY `id` (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=5 ;

--
-- Tablo döküm verisi `category`
--

INSERT INTO `category` (`id`, `name`, `top_id`) VALUES
(1, 'Computer', 0),
(2, 'Laptop', 1),
(3, 'Asus', 2),
(4, 'Phones', 0);

We want to make sth like this:

-Computer

— PCS

——Laptop

———Asus

-Phone

We use functions that call itself named recursive functions.

class CATEGORY
{
function cat($cat_id, $space= 1, $x ='') // cat id, space to add "_" degree of categoreis times, list of categories
{
$sql = mysql_query("SELECT * FROM category WHERE top_id='$cat_id'");

while($select = mysql_fetch_assoc($sql))
{

$this->x = $this->x.str_repeat('_', $space).$select['name'].'-';  // making a list with all categories names. we add "_" to in front of category name. It adds degree of category times. For example asus deggre is 2 therefore it will be __asus, pda's degree is one therefore it will be _pda

$this->x = $this->cat($select['id'], ($space+1), $this->x);  // function calls itself, with this, it finds subcategory of a category.
}
return $this->x; // This is list of all categories. Each category is separating with "-", be careful this is not an array , this is a string
}

function get_cat($cat_id)
{
$list = $this->cat($cat_tid);
$arr = explode('-', $list); // making array with categories
unset($arr[count($arr-1]);// deleting last element of array, because it is a blank
return $arr // return a array;

}

}

To use it

$example = new CATEGORY;
$get_array_categories = $exapmle ->get_cat(0);
print_r($get_array_categories);

I wrote this to show you how you can make a category system with unlimited subcategory. If my codes don’t woking fine, please
inform.

After some research i found codeigniter. Codeignter is an open source php framework. You can use it to make faster, easier web applications. Also it has rich php library. To understand how it works , you can watch video tutorial of Codeigniter from here

This code gets all information from your database table named category

$data['query'] = $this->db->get('category');

To get last 2 data i used only this code:

$data['query'] = $this->db->get('category',2);

Codeigniter makes up a form for your database tables to instert your data, you don’t have to write any mysql, and html code

i hope you like it

what does it do ?

it returns id generated from previous insert query.

Could you give some example ?

mysql_query("insert into product (name) values(aflower)");
if you want to print id of "aflower" you can use mysql_insert_id
echo mysql_insert_id();

!: to use mysql_insert_id your cloumn should be an auto_increment cloumn

A. Setting up mysql password is one of the essential tasks. root user is MySQL admin account. Please note that Linux / UNIX login root account for your operating system and MySQL root are different. They are separate and nothing to do with each other (indeed some admin removes root account and setup admin as mysql super user).
mysqladmin command to change root password

If you have never set a root password for MySQL, the server does not require a password at all for connecting as root. To setup root password for first time, use mysqladmin command at shell prompt as follows:

$ mysqladmin -u root password NEWPASSWORD

However, if you want to change (or update) a root password, then you need to use following command

$ mysqladmin -u root -p oldpassword newpass

Enter password:
Change MySQL password for other user

To change a normal user password you need to type (let us assume you would like to change password for vivek):

$ mysqladmin -u vivek -p oldpassword newpass

Changing MySQL root user password using mysql sql command

This is another method. MySQL stores username and passwords in user table inside MySQL database. You can directly update password using the following method to update or change password for user vivek:

1) Login to mysql server, type following command at shell prompt:

$ mysql -u root -p

2) Use mysql database (type command at mysql> prompt):

mysql> use mysql;

3) Change password for user vivek:

mysql> update user set password=PASSWORD(“NEWPASSWORD”) where User=’vivek’;

4) Reload privileges:

mysql> flush privileges;
mysql> quit

This method you need to use while using PHP or Perl scripting.

until know , it’s about changing password
how you can reset your mysql pass ?

To be able to modify the existing root password, you must firstly be connected to it. If you know the root password and just want to reinitialize it, you can skip this part. In the case that you don’t have the root password then follow the steps below.
It s is possible to bypass the authentication process and to access MySQL:

Stop the MySQL server.

#/etc/init.d/mysql stop

Restart MySQL, disabling network communication and skipping the authentication procedure.

#mysqld –skip-grant-tables –skip-networking &

Reinitializing the password:

Get connected to the system database (mysql) of MySQL:

# mysql mysql -u root

Type in the following command and reset your password

UPDATE user SET password=PASSWORD(‘newpassword’) WHERE user=”root”;

If you didn’t go through the first step, to validate the changes simply type:

FLUSH PRIVILEGES;

If you started MySQL manually(bypassing the authentication process), the server must be restarted:

#/etc/init.d/mysql restart
