[RESOLVED] Classes Tutorial

maximuss

Hi, im going through a tutorial from this site http://www.phpbuilder.com/columns/rod19990601.php3?page=1

I have this code so far that i copied from it:

<?php


class Style {

var $text;
var $alink;
var $vlink;
var $link;
var $bgcol;
var $face;
var $size;
var $align;
var $valign;

function Style ($text="#000000",$alink="#AA00AA",
$vlink="#AA00AA",$link="#3333FF",
$bgcol="#999999",$face="Book Antiqua",$size=3,$align="CENTER",$valign="TOP") {

$this->text=$text;
$this->alink=$alink;
$this->vlink=$vlink;
$this->link=$link;
$this->bgcol=$bgcol;
$this->face=$face;
$this->size=$size;
$this->align=$align;
$this->valign=$valign;

}

function Body() {

    PRINT "<BODY BGCOLOR=\"$this->bgcol\" ".
            "TEXT=\"$this->text\" ".
            "LINK=\"$this->link\" VLINK=\"$this->vlink\" ".
            "ALINK=\"$this->alink\"><FONT ".
            "FACE=\"$this->face\" SIZE=$this->size>\n";

}

function TextOut($message="&nbsp") {

    PRINT "<FONT FACE=\"$this->face\" ".
            "SIZE=$this->size COLOR=\"$this-> ".
            "text\">$message</FONT>\n";

}

}

$Theader= new Style;
$Theader->Set('text','#0000FF');
$Theader->Set('bgcol','#000000');

$Tbody=new Style;
$Tbody->Set('bgcol','#AAAAAA');
$Tbody->Set('size',2);


$Basic = new Style;
$Basic->Body(); 

$Basic->TextOut('This is my test message');
$Tbody->TextOut(' -- kinda neat, huh?');



?>

When i ran this i got an error saying "Fatal error: Call to undefined method Style::Set() in C:\wamp\www\classes.php on line 53"

Line 53 is the $Theader->Set('text','#0000FF'); line.

Can anyone help please?

Thanks.

The Set method doesnt not exist.

you will need to add a function for it;


function Set($var,$val){

$this->$var = $val;


}

Or since there are no private methods or anything (since it looks like a PHP4 example and you cant) you can also just do this


$Theader->text = '#0000FF';

// instead of 
$Theader->Set('text','#0000FF');

Hold Up!

I have another error now 🙁

it says: Catchable fatal error: Object of class Style could not be converted to string in C:\wamp\www\classes.php on line 45

Line 45 is the "SIZE=$this->size COLOR=\"$this-> ". line.

Does anyone know what the problem is now? :queasy:

Thanks.

SIZE=$this->size COLOR=\"$this-> ". line.

not sure what you are trying to do there. but you have a $this-> without anything at the end, ie. size like earlier in the line
