Okay, im having a go at building a class and am trying to make some vars which would be accessed like $page->title

so i have like this:

PHP Code:

class page {
 var $pgtitle;
 
 var $title         = setting('main_title', 'style_template');
 var $meta_robots   = setting('meta_robots', 'style_template');
 var $meta_keywords = setting('meta_keywords', 'style_template');
 var $meta_desc     = setting('meta_desc', 'style_template');
 var $footer_txt1   = setting('footer_txt1', 'style_template'); 


but im getting this error:

Parse error: syntax error, unexpected '(', expecting ',' or ';' in /home/ukcalm/public_html/includes/class/page.class.inc.php on line 7

Whats wrong?

I don't think its legal to pass a function when declaring vars. You can assign the values to the vars in the class constructor

class page {
var $pgtitle;
var $title;
var $meta_robots;
var $meta_keywords;
var $meta_desc;
var $footer_txt1;

function page() {
$this->title = setting('main_title', 'style_template');
. . .

oky so if i do that would i then be able to use them within the template like $page->title correct?

Dan

If the object is assigned to the var $page outside of the class, you can use it like that.

okay this is what i have so far in my class:

PHP Code:


class page 
{
 var $pgtitle;
 var $title;
 var $meta_robots;
 var $meta_author;
 var $meta_keywords;
 var $meta_desc;
 var $footer_txt1;
 var $footer_txt2;
 
 function vars()
 {
 $this->title         = setting('main_title', 'style_template');
 $this->meta_robots   = setting('meta_robots', 'style_template');
 $this->meta_author   = setting('meta_author', 'style_template');
 $this->meta_keywords = setting('meta_keywords', 'style_template');
 $this->meta_desc     = setting('meta_desc', 'style_template');
 $this->footer_txt1   = setting('footer_txt1', 'style_template');
 $this->footer_txt2   = setting('footer_txt2', 'style_template');
 }
 
 
 function last_update()
 {
  $last_update = setting('last_update', 'site_info');
   $last_update = strtotime($last_update);
   return date('d/m/Y H:i', $last_update); //Date time format can become a setting.
 } 


now the last_update func works,

but when i try to use $page->title it now showing anything (same for all of them)

what am i doing wrong?

Dan, 2 things...

First:
Use php5 declaration, if you can.
You can use the keywords "public", "private" and "protected".
The php4 declaration, like you used, default to "public" in php5.

Public means that the property/function is accessible from the outside of the object.
Private means the property/function is accessible only in the object.
Protected means that the property/function is accessible only from the object or from an object who's extended the parent object.

PHP Code:

class clTest{
  public $title;
  private $content;

  public function __construct($title,$content){
    $this->title=$title;
    $this->content=$content;
  }
} 


and in PHP4:

PHP Code:

class clTest{
  var $title;
  var $content;

  function clTest($title,$content){
    $this->title=$title;
    $this->content=$content;
  }
} 


the __construct function is the constructor in PHP5. In PHP4, it's a function that have the same name as the class. in this case, it would be a function clTest($title,$content);

Second:
When the constructor have parameters, you can get them when you create an object of your class

PHP Code:

var $obj=new clTest('This is the title','This is the content'); 


Okay sorry but you lost me after the public/private thing.

Think of my like a gold fish. (at the moment im still banging my head at the glass because i can see a reflection of food which is behind me...)

okay i didnt know that var was for php, will change now.

but whats the other thing im confused now :s

i dont see why its not working, im using a mysql db class i have as a basis :s

Dan, is the function setting() declared as a function outside the scope of the class? If not, you will need to build it, or if the setting() is declared inside your class, it will nedd to be accessed by $this->setting()

the setting() func is declared outside the class, and i know that it works because it works within the last_update function, which at present is the only part which works...

So as far as i know the setting() is not the prob. just syntax and a moron (me)
