class extend trouble.

[Domcsore]

Hey there, I have 3 files.

 

my index.php

global_reg.php

template.config.php

 

this is what i have:

 

index.php -

<?php 
include_once('classes/global_reg.php');
$global_conf = new globalconf;

/** LOAD ENGINES **/
$global_conf->engineload("template.conf.php");
$global_conf->echome();

?>

 

Then global_reg.php (I wont display it all) -

<?php
class globalconf{
/** DEFINE VARIABLES **/
public $loadengine;


public function engineload($classfile){
	$this->loadengine = array(
							  "class"=>"classes/subclasses/"
							  );
	include_once($this->loadengine['class'].$classfile);
}
}
?>

 

and template.config.php

<?php
class template extends globalconf{

public function echome(){
	echo "Me";
}
}
?>

 

but im getting the error:

 

Fatal error: Call to undefined method globalconf::echome() in index.php on line 7

I don't think you're looking at extend in the right way.  It doesn't extend your current class.  It specifies that one class (template) is the child of a parent class (globalconf).  Your parent class doesn't have access to members defined in the child.  So globalconf doesn't magically get the  echome method you define in template.

my OOP isn't great but I believe you need to create a template object in order to call echome. you can't just include it in your engineload.

 

plus inheritance only goes the other way. i don't think a globalconf object could call a template function unless you casted it? where as a template object would inherit all the globalconf member functions because it extends globalconf.

I think

 

$global_conf = new globalconf;

 

should be

 

$global_conf = new template;

 

You are creating an instance of template (which extends from globalconf). Thus by having an instance of template, you should have access to globalconf's public methods and properties.
