Ok, im trying to design a template system (very basic atm and please dont recomend any

as i am making my own).

Now i think ive done everything right but i am getting the following error:

Fatal error: Call to a member function on a non-object in C:\apache2triad\htdocs\cms\test.php on line 79

Now this is the following code i have:

skin/1/skin_test.php

Code:

class skin_test {

function some_text() {

echo <<<HTML
blah
HTML;

  }

}

now in test.php i have:

Code:

include("skin/1/skin_test.php");
$html 		= new skin_test;

I then go down a little (into a function) and i global $html and then i have:

Code:

	$html->some_text();

If anyone could point out what i am doing wrong, because i surly can't find it. Thank you very much.

Classes that don't have any member variables cannot have their functions called with the -> syntax. Instead, you have to use the scope resolution operator :: . So, for example, you'd call your function like this:

skin_test::someText();

*edit: Err, I confused member-less classes with uninstantiated classes. Whether a class has any members is irrelevant to being able to access its methods (unless the methods depend on there being certain vars). The scope resolution operator is for accessing methods in uninstantiated classes or parent classes.

ok well when i put that in i get the error:

Fatal error: Undefined class name 'skin_test' in C:\apache2triad\htdocs\cms\test.php on line 79

Try passing $html into the function and see if that works.

nah didnt work

edit* found out the problem, when i put:

include("skin/1/skin_test.php");
$html = new skin_test;

into the function it works, so i have to figure out how i was trying to do it before, if you have any suggestions please let me know.

Well, this works, so there is something else wrong.

PHP Code:


class skin_test {



function some_text() {

echo <<<HTML

blah

HTML;



}



}



$html = new skin_test;

$html->some_text();
