Hello World !

I would like the background to get automatically adapted to the screen resolution.

So, here is what I did, but I get an erro message, let me show you :

First I wanna get the User Screen through a Cookie (I definitively don't want it to get by the GET method) :

Code:
&lt;?php

if(isset($_COOKIE["users_w"])){

 $screen_w = $_COOKIE["users_w"];

 $screen_h = $_COOKIE["users_h"];

}else //means cookie is not found set it using Javascript

{

?&gt;

[removed]

writeCookie();

 // Ma première fonction Javascript !

function writeCookie(){

 var today = new Date(); // On rentre d'abord la date de création du cookie

 the_date.setTime(the_date.getTime()+60000); // On rentre ensuite la date de péremption du cookie

 var the_cookie_date = the_date.toGMTString(); // On l'adapte à GMT ?

 var the_cookie1 = "users_w="+ screen.width; //On enregistre le width dans cookie1

 var the_cookie2 = "users_h="+ screen.height; //On enregistre le height dans cookie2

 var the_cookie1 = the_cookie1 + ";expires=" + the_cookie_date; // ON rajoute les dates de peremption

 var the_cookie2 = the_cookie2 + ";expires=" + the_cookie_date;

 //commandes pour enregistrer le cookie chez l'utilisateur dans un petit tableau

 [removed]=the_cookie1 

 [removed]=the_cookie2

 // Et on dit ou il va 

 location = '&lt;?php base_url();?&gt;';

}

&lt;/script&gt;

&lt;?php

}

echo "Your screen resolution is set at ". $screen_w."xxx".$screen_h; // Just to be sure

?&gt;

Forget about the French comments, useless Smile

Then, I get my pic and load the librairy I found there :

Librairy : http://ellislab.com/forums/viewthread/178095/

Then I get my image in a variable

Code:
$Pic="Paris.jpg";

That I want to give to the function right after, so I get :

Code:
&lt;?php 

//Dans cette partie nous nous occupons de la selection du fond d'écran selon la ville et l'heure

 $Pic="Paris";

 $this->load->library('Images');

 $this->images->resize(base_url().assets/images/background/.$Pic.".jpg" , base_url().assets/images/background/.$Pic."Resized.jpg" , $width, $height);   

?&gt;

So considering the Directions for the Image Manip librairy, we should have something la this :

Code:
$this->images->resize('full_path on image', 'path of new image', '120','90'));

All this code is here in order to get a resized image background so that right after this code I have

Code:
&lt;body background=" &lt;?php echo base_url();?&gt;assets/images/background/&lt;?php $Pic ?&gt;Resized.jpg" &gt;

And you will find this code in the header of my website.
Just before the logo get printed.

That what I think I did ... I'm not sure about the images paths, does base_url().assets/images/background/.$Pic.".jpg" work ?
Well definitively not, I don't know how to do something like this.
So I tried first with static paths like assets/images/background/Paris.jpg for each of the url (No need to rewrite it here .. well let's do it :

Code:
$Pic="Paris";

 $this->load->library('Images');

 $this->images->resize(localhost/codeIgniter/assets/images/background/Paris.jpg , localhost/codeIgniter/assets/images/background/ParisResized.jpg , $width, $height);  

?&gt;

 &lt;body background=" localhost/codeIgniter/assets/images/background/ParisResized.jpg" &gt;

)

So now here is me problem :

Here is my error message I get when I try :

Quote:A PHP Error was encountered

Severity: Notice

Message: Undefined property: CI_Loader::$images

Filename: template/header.php

Line Number: 109

Fatal error: Call to a member function resize() on a non-object in D:\Programmes\wamp\www\codeIgniter\application\views\template\header..php on line 109

So line 109 is this one :

Code:
$this->images->resize(localhost/codeIgniter/assets/images/background/Paris.jpg , localhost/codeIgniter/assets/images/background/ParisResized.jpg , $width, $height);

Why isn't it considered as an object ?
