PHP - Static Issue

heres an example of the code i have
Code: [Select]
class someclass
{

public function run($parm)
{
system($parm);
}

public static function create($item1,$item2)
{
$this->run($item1 . $item2);
}

}

then i have a file that attempts to use the create method:
someclass::create($one,$two);

when interpreting, i get this error: "Using $this when not in object context in"

does anyone know how I can fix this? I think I understand why its wrong (the class hasn't really been set up) - I just dont know how to correct it. Is there a way I can access class functions without using $this ? additionally I tried making the run method static too, but that didnt seem to work.

I removed the last half of the file, but what makes the login($username, $password) function not static? I want to access it statically, but I am getting an error. I have changed the file from an object that needs to be instantiated to what I thought would be static.

Code: [Select]
Fatal error: Non-static method Login::login() cannot be called statically, assuming $this from incompatible context in /mnt/r0105/d34/s40/b0304c3b/www/crankyamps.com/include/uploads/pages/login.php on line 25
Line 25.
Code: [Select]
Login::login($username, $password);

I'm looking for some advice on the best way to achieve the following...

I'd like to change the way URLs are shown for our search results pages.

The website is a holiday rental website and currently the URLs look like this:

domain.co.uk/search?region=[value]&type=[value]&budget_low=[value]&budget_high=[value]&name=[value]&size=[value]

Ultimately I'd like them to look more like this:

domain.co.uk/region-value/type-value/budget_low-value/budget_high-value/name-value/size-value.

Any advice would be greatly appreciated.

I have a bunch of quasi-static values that must be available to the application.  Most of them are set based on settings in a configuration file.  Others are based on GET, COOKIE, or SESSION values, and utilize the database to get the actual values.  The values will never be written to or modified by the application, only read.   It seems to me that I could create some sort of superclass which includes static methods and properties, and I could access any value by something like superclass::get('some.value');  I could design the class so that the values are queried from the DB or obtained from a parsed file only the first time they are requested, and for future requests, retrieved from a static property.   That being said, I have been told from more than one person that I am just doing it "wrong".   Please let me know what is wrong about it.   Thank you

Is it ok to do this?
Code: [Select]
class Two {

 function anything() {
   classOne::anyMethod();
 }

}

I'm sure it is but this doesn't pose very well for if I wanted to swop out one class for another. I'd then have to make changes to the code (unless I were sure all classes were named the same).

--

What I want it for (and this may be another issue), is this:

I may need to create more than one database instance:
Code: [Select]
//Database exends mysqli
$db[1] = new Database(2);//database 2 used this time
$db[2] = new Database(5);//db5

I then always use Database::closeAll() at any point in my script to ensure all connections are closed. Of course $this->close wouldn't close all instances/connections, just the one I was working on.

I know I don;t have to close all connections, but I may as well, and there are other occasions where the first part of this question applies, so please don't just respond "no need to close".

Database::closeAll() is this:
Code: [Select]
public static function closeAll() {

//closes ALL active instances (not just this one)

global $db;

foreach($db as $v) {

$db[$v]->close(); unset($db[$v]);

}
        }

Hey guys, this is just a general question.

I read about late static binding and started developing with it on my local server but I noticed that hostgator still runs on 5.2..

Should I use late static binding? (im planning to code an open source CMS)

I finally got my kml to display through the static maps api thinking I could then display my map on the pdf I'm generating using mpdf.  But,  it is not displaying the image in the pdf.  It works fine on a blank test page.

$kmlMap = "<img src=\"http://maps.googleapis.com/maps/api/staticmap?zoom=15&size=500x300&maptype=hybrid&path=color:0xff0000ff|weight:3|$correctedCoords \" /><br />";

Any ideas on how I could make this work with mpdf?

Hello, my first post here.

I created a Validation class that depends entirely on static methods. It appears to be working well, but perhaps I misunderstood exactly the purpose and the consequences of using static methods.

My class essentially looks like this:


class Validate
{
static public $errors  = array();
static public $valid   = array();

static public function Name($name)
{
if ($name != '')
{
self::$valid['name'] = $name;
return true;
}
                                else
                                {
                self::$errors['name'] = 'Name is empty';
                return false;
                                 }
}
}


Does this create any chance whatsoever for a collision of data from multiple users? I am beginning to think it does, simply because from what I have recently learned about static methods, theyr'e essentially global variables because they are not instantiated. If that's the case, then it would seem possible that during times of heavy use, any application depending on this class would confuse submitted data.

Any thoughts?

Thanks in advance.

so my situation is something like this , i'm trying to fetch user details based on `id` that isset is getting, but some how the `variable that contains the $_GET value doesn't work` in query but when i put an static value to pdo query then it works and show the result. i have checked by doing `var_dump` of variable `$user` before query and it shows the correct value but not working in query. Below is the code i'm working with:

Ok, my php skills are such that I can customize an existing script to some extend, but I can't write one.

My problem is the following:
I'm using a php-based forum script in a friends website. I load the 'forum.php' script  in an iframe of a static page.

When a user gets a response to a post that he wrote on the forum, he receives a mail with a link which - if clicked - gets him to the response he got ie. http://someurl.com/forum.php?todo=viewtopic&tid=6#t2

The problem is now that if he clicks the link, the file of course doesn't open in the iframe of the static page (http://someurl.com/forum.html) where normally this forum.php file opens.

I guess I will have to make the static page also into a php-file and then use parts of the clicked url (forum.php?todo=viewtopic&tid=6#t2) and insert it into the iframe as the file to load ... would appreciate a lot if anyone can advice me how to do that!

Thanks in advance,
K.

Here i am not getting how to store it in that table. Actually all the 24 inputs are not mandatory. If user fills only 2 then also it should store it in the database table.    I tried to do like this

if(isset($_POST['save']))
{
$roll_no = 	$_POST['roll_no'];
$ins_amt1 = $_POST['installment1'];
$due_date1 = $_POST['due_date1'];
$ins_amt2 = $_POST['installment2'];
$due_date2 = $_POST['due_date2'];
$ins_amt3 = $_POST['installment3'];
$due_date3 = $_POST['due_date3'];

$msql = 'INSERT INTO installment (id, fee_id, student_id, amount, due_date, paid_date, status, rec_no) VALUES '.implode(', ', $items);

But it is taking only one data. Can somebody please suggest. The data has to be saved like this  saveddata.JPG   70.92KB   0 downloads   Somebody please help. Thank you  

Hello,

If I have an index file with:

date_default_timezone_set('GMT');
error_reporting(E_ALL | E_STRICT); 

abstract class A {
    abstract public static function YesIReallyMeanAbstractStatic();
}

class B extends A {
    public static function YesIReallyMeanAbstractStatic() {
    }
}


This will not error.

However if I have:


date_default_timezone_set('GMT');
error_reporting(E_ALL | E_STRICT); 

require('class_a_in_a_different_file.php'); // Or use __autoload() to do the same.

class B extends A {
    public static function YesIReallyMeanAbstractStatic() {
    }
}


This will throw the error:
"Static function A::YesIReallyMeanAbstractStatic() should not be abstract"

I know abstract statics are debatable...
but it makes no sense to me for it to be allowed in the first example but disallowed in other.

So I was wondering if this is a bug? Or is there something else going on here?

I assume the parser is evaluating the included file and then throwing the error which doesn't happen if both classes are in the same file as they can then be evaluated altogether.

I have 2 php files. I am unable to get B's global variable from A's static method:

A.php
Code: [Select]
class c_A
  { public static function f_A()
      { include_once( "B.php" ) ;
        print f_B() ;
      }
  }
c_A::f_A( ); // only prints "B : "

B.php
Code: [Select]
$gvs = "global variable from B" ;

function f_B()
  { return "B : " . $GLOBALS[ "gvs" ] ;
  }


any thoughts?


thanks,
Shannon

I have the following simple class:

Code: [Select]
class Settings {
  public static $mysql_datetime_format = "%c/%e/%Y %l:%i %p " . date("[T]");
}

And referencing like:

Code: [Select]
echo Settings::$mysql_datetime_format;

But, I am getting the error: Parse error: syntax error, unexpected '.', expecting ',' or ';'.

Why is this invalid?

Hi All,   I'm trying to return HTML page contains the Russian characters sent as POST variables and also static data as part of HTML result.   I'm not able to put it work together.   If I set windows-1251 - the static data displayed incorrectly. If I set UTF-8 - the dynamic (POST) data displayed incorrectly   Any thoughts?   Thank you very much in advance, Evgeny    Following is the simple HTML example and also Fiddler request example <?php
