[normal class, abstract class, interface, polymorphism...]

hi there

 

im am making a php validation class with sub classes that extend it, eg, mobile, suburb, credit_card, ect

 

so, the idea is you can call

 

$validation = new Validation('mobile');
$valid = $validation->validate($number);

$validation->type('suburb');
$valid2 = $validation->validate($suburb);

now my idea for doing this is having

 

class Validation {
    private $v_type = null;

    function __construct($type) {
        $this->type($type);
    }

    public function type($type) {
        $this->v_type = new $type();
    }

    public function validate($info) {
        return $this->v_type->validate($info);
    }
}

as a very basic example

 

but is there a better way of doing this?

[6014359000000928 % 8 = 7...]

hi there,

 

 

well here is what i am doing:

 

 

 

$flybuys: 6014359000000928

$check: 8

$total = (array_sum($odds))+$evens;
    $total = str_split($total);
    $check = 10 - $total[1];
    echo $flybuys.' % '.$check.': '.$flybuys % $check.'<br />';
    $res = $flybuys % $check;
    echo 'res: '.$res;

 

 

and the output is:

6014359000000928 % 8: 7

res: 7

yet if i do:

echo 6014359000000928 % 8;

i get: 0;, which is correct

so where is the 7 coming from?

[if statements - are these the same]

My last comment still stands. its really not worth my time reading or posting in this thread.

 

and in a whole is entirely unhelpful :|

 

 

[if statements - are these the same]

here is a set of if statements that i am trying to optimize

 

These type of micro optimizations are generally a waste of time.

 

maybe so, but i am doing optimization on the entire code, so i might as well.

[if statements - are these the same]

so basically here is a set of if statements that i am trying to optimize, can you please tell me if there are any differences in processing between them

 

 

if($id!="0"    && $status!=""           && $msg_body=="")
if($id != 0    && !empty($status)    && empty($msg_body))

 

 

AND

 

 

 

if($message_type == 0    && $msg_link_id != "0"   && $status==""         && $msg_body!="")
if($message_type == 0    && $msg_link_id != 0     && empty($status)    && !empty($msg_body))

 

 

AND

 

 

if($message_type == 0    && $msg_link_id=="0"    && $status==""         && $msg_body!="")
if($message_type == 0    && $msg_link_id == 0    && empty($status)    && !empty($msg_body))

[format mysql datetime with php]

just normal date time i.e 2010-07-01 22:42:21

[format mysql datetime with php]

thorpe do you ever sleep?

 

haha but yeah, i thought about doing that,

 

except this table has over 300 columns (not designed nor can be changed by me) and so the query is is select * ...

 

 

while($row = mysql_fetch-assoc...)

{

foreach($row as $k => $v )

  $$k = $v;

 

 

so i cant really do it in the query

 

 

cheers.

 

 

came across using strtotime on it before using date

[format mysql datetime with php]

hi there,

 

 

how should i go about formatting a mysql datetime with php?

 

 

i have tried Date('jS M Y', $qry['msg_add_date']) but i simply get 1st Jan 1970

[simple xml, differences]

bump

[simple xml, differences]

hi guys

 

so, can anyone tell me why i end up with different results with each of these

<product_display_price> </product_display_price> = 
[product_display_price] => SimpleXMLElement Object
               (
                   [0] =>
               )

 

 

<product_display_price>Ham $5.00</product_display_price> = 
[product_display_price] => Ham $5.00

 

 

<product_display_price/> = 
[product_display_price] => SimpleXMLElement Object
               (
               )

 

all i did was

 

$xml = simplexml_load_string($this->xml_data);

 

        echo '<pre>';

        print_r($xml->xpath('/menu/products_list/product'));

        die('</pre>');

 

so, why does an empty element give me an empty object

^ expected

 

a element with a string in it give me a string

^expected

 

yet a element with a " " string gives me an object with a " " string in it

^not expected

 

i would have expected it to act as either a string or an empty element

[edit previous variable]

damn,

 

i think ill rather rewrite the app than use that on every include...

 

thanks anyway

[edit previous variable]

see one way i could do it is to call

 

$content = ob_get_contents();

ob_end_clean();

//replace stuff here

echo $content;

 

which would work fine, as i could just put ob_start before the echo $content;

 

but is there a tidier way to do this?

 

 

 

so the entire thing to replace would actually be

 

 

$content = ob_get_contents();
$headers = array();
    if ( !headers_sent() ) 
      $headers = apache_response_headers();
ob_end_clean();
//replace stuff here
ob_start();
if ( !empty( $headers ) )
    foreach ( $headers as $name => $value )
        header( "$name: $value" );
echo $content;

   

 

 

[edit previous variable]

then what would you suggest for when you have a default page layout

 

 

i.e

 

 

<html>
<head>
<!--stylsheets here -->
<!--javascript here -->
</head>
<body>
<!--header div -->
<!-- menu div -->
<?php include($_GET['page.php']; ?>
<!-- footer div -->
</body>

 

 

and its not pratical for your site to include the header, footer, and menu divs from anther file

 

 

now in the the include file you want to change the site title,

and include another style sheet,

 

 

so my idea was to have a placeholder variable in the head which i could edit.

 

 

i am already calling ob_start() at the beginning of every every page so could i use that to edit it?

[edit previous variable]

Hi guys,

 

 

if i have a variable (lets call it $page for now)

and i echo it here (echo $page;)

and i include a page here

how in the included page can i edit the text that was echoed above?

[wierd output in links]

8D yeah just saw that,

 

so it means that the actual link that was being created was

<a href="messaging">

 

which explains it.

 

I think i kinda deserve anything you give me now lol.

[wierd output in links]

That is the code there

<a href="<?php $config->base['url_path']; ?>messaging">Messaging</a>

 

the config class is just an empty class with magic methods for get and set

 

so i define config things like so

 

 

$config = new Config();

 

 

//BASE SETTINGS

//------------------

$config->base = array();

$config->base['abs_path'] = $abs_path;

$config->base['url_path'] = 'http://localhost/buzzil/';

$config->base['temp_dir'] = 'tmp/';

$config->base['env']      = 'dev';

 

 

 

so the expected output from accessing any url with this code in the file

<a href="<?php $config->base['url_path']; ?>messaging">Messaging</a>

is

<a href="http://localhost/buzzil/messaging">Messaging</a>

 

 

but instead from a url such as

http://localhost/buzzil/templates/list/email

 

 

i get

<a href="http://localhost/buzzil/templates/list/messaging">Messaging</a>

 

and yes thorpe,

at midnight when i have had less than 3 hours sleep in the past 48 hours i do fail at spelling

[wierd output in links]

 

if i have this in a config file

$config->base['url_path'] = 'http://localhost/buzzil/';

 

 

and i have this

<a href="<?php $config->base['url_path']; ?>messaging">Messaging</a>

 

 

any idea when i am on a page iwth a url like

http://localhost/buzzil/templates/list/email

 

 

why instead of the expected output of

<a href="http://localhost/buzzil/messaging">Messaging</a>

am i getting

<a href="http://localhost/buzzil/templates/list/messaging">Messaging</a>

 

 

dont know if it will help but here is my htaccess file

 

 

Options +FollowSymlinks

 

 

RewriteEngine on

 

 

RewriteCond %{REQUEST_FILENAME} !-f

 

 

RewriteRule ^(.*)$ index.php?page=$1

[validate form submission source]

@Shadiadiph

We were looking at something like that, just wondering if there was an easier way, thanks

 

@5kyy8lu3:

The HTTP_REFERER can be spoofed so it is unreliable

[.htaccess /login = index.php?page=login]

Hi guys,

 

 

what do i write in my htaccess file so that when a user visits

 

 

mysite.com/login

it actually loads mysite.com/index.php?page=login

[php validate phone number]

[validate form submission source]

Hi guys,

 

 

I have a page which submits a form via ajax

the form submits to add a new user

users can only access this page if they are logged in,

 

 

so my question is how do we validate to make sure that the requests are coming only from that page?

 

 

we thought about validating via the request ip but if the form is submitted via ajax would that not just be the clients ip?

Hailwood

[how to access these]

ok, so you know the times when you feel really stupid?

 

yeah this is one of them,

 

i can get to them doing $this->config->database['name'];

 

the error had nothing to do with me trying to access them,

 

the error was because i was doing

$this->$link

by accident instead of

$this->link

[how to access these]

 

Current Status

[how to access these]

strange this is if i do this:

$this->link = $this->config->database['pass'];                             //line 45
        $this->$link = mysql_connect(                                          //line 46
                $this->config->database['host'],  //Database Host
                $this->config->database['user'],  //Database User
                $this->config->database['pass']); //Database Pass

 

 

i get

Fatal error: Cannot access empty property inC:\server\xampp\htdocs\buzzil2\classes\database.class.php on line 46so why dont i get this error on 45?

wondering if one of the values was not set properly i went through and changed 45 to user/host/pass/ in turn, but still no error

[how to access these]

dunno if it will help but this is how i store the info

//GET AN INSTANCE OF THE CONFIG CLASS
$config = Config::getInstance();

//DATABASE SETTINGS
//------------------
$config->database = array();
$config->database['host'] = 'localhost';
$config->database['user'] = 'root';
$config->database['pass'] = '';
$config->database['name'] = 'buzzil';

the config class has

    public static function getInstance() {
        if (self::$instance== null)
            self::$instance= new config();
        return self::$instance;
    }

    public function __set($k, $v) {$this->$k = $v;}
    public function __get($k) {return $this->$k;}
