PHP UPLOAD CLASS

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

 30000, "application/pdf" => 4000 );
 // %year% for year, %month% for month, %day% for day, or just write exact path.
 var $path ='alper/%year%/%month%/%day%';
 // false don't give a new name, true give a new name.
 var $new_name = FALSE;
 var $path_right = '0777';
 var $error = "";
 var $is_error = FALSE;
 public function control_file($file) {
 if (!array_key_exists ( $file ['type'], $this->file_types )) {
 $this->error='this type is not allowed';
 $this->is_error = TRUE;
 }
 else {
 if ($file ['size'] > $this->file_types [$file ['type']]) {
 $this->error="file is too big";
 $this->is_error = TRUE;
 }
 }
 }

 public function upload($file,$path="",$new_name="") {
 $this->control_file($file);
 if ($this->is_error) {
 echo $this->error;
 }
 else {
 $ext = substr(basename($file['name']), strrpos(basename($file['name']), '.') + 1);
 //giving name start
 if($this->new_name)
 $filename = time().".".$ext;
 else
 $filename = basename($file['name']);
 //giving name finish

 // Replace path with real value start
 $path_keys = array('%year%','%month%','%day%');
 $replace_keys = array(date("Y"),date("m"),date("d"));
 for($i=0;$i<=2;$i++) {
 $this->path =str_replace($path_keys[$i], $replace_keys[$i], $this->path);
 }
 $umask = umask(0);
 if(!is_dir($this->path)) {

 if(!@mkdir($this->path,0777,true)) {
 $this->error="can not create a folder";
 $this->is_error = TRUE;
 }

 }
 if(!@move_uploaded_file($file['tmp_name'], $this->path.'/'.$filename)) {
 $this->error="can not upload file";
 $this->is_error = TRUE;
 }
 umask($umask);
 }
 }
}

How to get page url with php

ALonon — Thu, 04 Mar 2010 00:30:23 +0000

I needed a function to get (learn) url with php.
Here are the codes.

function curPageURL() {
$pageURL = ‘http’;
if ($_SERVER["HTTPS"] == “on”) {$pageURL .= “s”;}
$pageURL .= “://”;
if ($_SERVER["SERVER_PORT"] != “80″) {
$pageURL .= $_SERVER["SERVER_NAME"].”:”.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
?>

To use this function write

Unlimited Subcategory with Adjacency List Model

ALonon — Sun, 01 Feb 2009 16:38:52 +0000

I found two model two make to make category system with unlimited category one oft them is Tree traversal, and other is Adjacency list model.

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.

Codeigniter

ALonon — Fri, 30 Jan 2009 21:20:14 +0000

While i was talking to mehmet ,he mentioned about php frameworks. I heard somethings about them but not realy knew what they do.

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

mysql_insert_id

ALonon — Sun, 25 Jan 2009 22:34:14 +0000

mysql_insert_id() is a very usefull function..

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

Difference between include and require

ALonon — Sun, 09 Nov 2008 12:04:20 +0000

Difference between include and require: if you use include and there is not page that you include , you get a warning. Otherwise if you use require instead of include you will get a fatal error.
